How are you printing out the date? If you're 1 second from midnight you may be in Saturday still depending on your date formatter. Also what calendar are you using?

Not printing out the date, just looking at the NSDate object's description in the debugger.

I've tried using the [NSCalendar currentCalendar] or also the Gregorian calendar and both give the same results. I've also tried setting the timezone to no avail.

I got angry and ended up doing this instead:

code:

// Change the day to the difference of today's weekday to sunday (which starts at 1, not zero)
[nowComponents setDay:(nowComponents.day - (nowComponents.weekday - 2))];
[nowComponents setHour:0];
[nowComponents setMinute:0];
[nowComponents setSecond:0];
        
NSDate *previousSunday = [calendar dateFromComponents:nowComponents];

Basically sets the day to the difference between the current work day and Sunday. Tried it on a bunch of dates, even handling going between years and months and it worked.

I have a problem with opening a UIDocument in a timely manner, and I think it�s because its asynchronous behavior is pushing the end of a busy queue. Here's the scenario:

1. At launch the app scans the Documents folder for all the user's documents.
2. For each one, a UIDocument is allocated, -readFromURL: is called, and is metadata is opened so that things like tags can be cached.
3. Each UIDocument is UIDocumentChangeCleared, and -closeWithCompletionHandler is called. This causes it to -dealloc.

Meanwhile, the app has already finished launching, and the user can select a new document to load. If they do this before all the above scanned documents have -dealloc called, there is a looooooong wait before it opens until all the -dealloc calls finish.

How can I track this down? I�ve tried every iteration of moving the scan to its own background thread, but the -openWithCompletionHandler call on the user-selected document always waits for the scan to finish.

I'm attempting to draw a string ( in this case a single character of a font that contains icons ) with an outline. Using this code

code:

      CGContextSetFillColorWithColor(cg, [[UIColor redColor] CGColor]);
      CGContextSetLineWidth(cg, 1);
      CGContextSetTextDrawingMode(cg, kCGTextStroke);
      [actualIconString drawInRect:textRc withFont:font lineBreakMode:UILineBreakModeClip alignment:UITextAlignmentCenter];
      
      CGContextSetFillColorWithColor(cg, [actualIconColor CGColor]);
      CGContextSetTextDrawingMode(cg, kCGTextFill);
      [actualIconString drawInRect:textRc withFont:font lineBreakMode:UILineBreakModeClip alignment:UITextAlignmentCenter];

I get an outline but it's not uniform

For whatever reason the outline doesn't appear at the left and bottom.Is there a better way to draw text with an outline that will give me a uniform stroke?

Edit: I know a stroke of 1 will only get me a 0.5 stroke outline since the stroke should be centered on the path. A stroke of 2 has a similar ununiformity

Try offsetting your drawing position by 0.5 pixels

Better, but still isn't uniform.

It ends up making it look like a bezel and not an outline, which is what I'm going for.

Why are you drawing the fill after the stroke? Seems reversed to me.

# ? Jan 13, 2015 19:25

Doc Block: Apr 15, 2003; Fun Shoe

Take into account the width of the stroke when drawing your fill. See what happens when you make the stroke width 2 and then offset your fill by +1 +1 or +0.5 +0.5.

Also, it might be strangeness resulting from it being done with text rendering. Try converting that particular glyph into a CGPath and then drawing that.

Since the stroke is centered on the geometry, if you draw the stroke after the fill it will encroach on the glyphs.

Looks like the CGPath approach is the best - I can get a perfectly uniform stroke outline. The only problem is I can't get the correct glyph from my symbol font. I don't know if the issue is related to the fact that the font starts at glyph 0xF100 but when I pass the single character string ( which works perfectly fine with [NSString drawInRect:] ) I get the wrong glyph. The code below gives me 0xF121 when I pass in 'B' ( 0x0042 ). Something's is probably wrong in my CoreText code - I was mainly doing Physics 101 units conversion to get from a NSString to a CGPathRef.

code:

      CTFontRef f = CTFontCreateWithName((CFStringRef)@"fontcustom",imageView.frame.size.height, nil)
      CFDictionaryRef dict = CFDictionaryCreate( NULL, NULL, NULL, 0, NULL, NULL ):
      CFAttributedStringRef attStr = CFAttributedStringCreate ( NULL, (CFStringRef) @"B", dict );
      CTLineRef line = CTLineCreateWithAttributedString( attStr ) ;
      CFArrayRef runArray = CTLineGetGlyphRuns(line);
      CTRunRef run = (CTRunRef)CFArrayGetValueAtIndex(runArray, 0);
      CFRange thisGlyphRange = CFRangeMake(0, 1);
      CGGlyph glyph;
      CGPoint position;
      CTRunGetGlyphs(run, thisGlyphRange, &glyph);
      CTRunGetPositions(run, thisGlyphRange, &position);
      CGPathRef path = CTFontCreatePathForGlyph(f, glyph, NULL);

Could someone give me a quick rundown on FMDB?
Is generally preferred to use than the standard sqllite libraries?

I've done some messing around with sqllite and I can create my DB in the 'documents' folder.
Is there anyway to transfer that database to my computer?

I think you can include a .sql or whatever file in your xcode project and have it be a part of the IOS app but that's a one way street, right?

I haven't actually used FMDB but from the many times I've looked at it, it's a handy but small wrapping of the SQLite library with a dispatch queue convenience. If it makes you more comfortable then go for it, if you don't think you need it then you're probably right.

You can plug your device into iTunes (cable or wifi if wifi syncing is enabled) to get data in and out of the documents folder. Otherwise you can attach it to an email, airdrop it, whatever you feel the need to do. Be aware of options like write-ahead logging that turn your database into a multi-file affair (i.e. use FMDB/SQLite API to move the database around if it's more than one file).

A decent Objective-C interface and distribution of sqlite3 for iOS and Mac OS. Has some highly-recommended queue classes to manage concurrency a little bit instead of you rolling your own to varying degrees of success or failure.

TheReverend posted:

The iOS system's version of SQLite has sane defaults (WAL, aka Write-Ahead Logging is default on iOS's system version of SQLite, whereas you need to set that by hand on standalone SQLite), but they are a bit dated. Recent SQLite versions are faster and you can do spiffy things like virtual database table plugins and full-text search. There's a ready-made CocoaPod to install it; it's quite easy to sub it in instead of using the system version. Using any of the non-default FMDB subspecs will also get you the standalone version. That said, if you have conventional needs and you're not trying to squeeze out every last bit of performance out of your database, you can just stick to the default iOS system SQLite library.

Don't do that lest you risk rejection from the App Store: SO link. Put it in the Caches directory: Apple docs. Unless your app is explicitly something which edits SQLite files, or you use SQLite as a file format for the data you actually care about saving.

AirDrop is one possible option: blog post.

You can include a pre-baked sqlite file, but you'll need to copy it to a directory your app's going to save the database in. I personally am using FMDBMigrationManager which seems to be mostly adequate. An alternative to copying the file is to create a new database, attach the old database to the new database (SO link), migrate the data, then close the old database. Do note that WAL databases aren't openable in read-only mode, though (PRAGMA journal_mode=DELETE is strongly advised for storing any read-only databases).

Well gently caress.
My thinking was that if a user's database got a hosed up they could send me the .sql file and I could see what went wrong/ try to fix.

Thanks though. I'm going to give FMDB a look.

Ah. Yeah you can definitely do that, but you'll have to do it in a way other than through keeping it in the Documents folder. Creating a file URL and sharing it to email would be a good way to do that. Of course, this is only possible if you don't crash on startup when trying to read your database.

Also, .sql is usually the file extension for text sql containing stuff like inserts and stuff to be inserted into databases. .sqlite is the file extension for the actual databases. Don't call your database files sql files and don't call your database files sql files.

Just a note (for the OP, I assume you know this Doctor), the system can and will delete the contents of your app's Caches directory while your app is not running. If you're genuinely caching replaceable data in your database then put it in Caches, otherwise you want the Application Support directory.

Ah yeah, sorry, quite right, I generally write stuff that consumes web APIs, and persistence isn't a strict requirement.

And a re-reminder that if you're not using the system sqlite3, you may have WAL disabled. I suggest enabling it (just need to run a pragma statement). Free speed, yo.

E: Actually, not free because you want to be able to send the file, but I don't really know the scope of your project so I don't know what's a good tradeoff for you.

Hey guys, I have an unusual question, and please forgive me if this isn't a good place to ask.. It's not a question specifically about code, however this seemed to be the best place to find someone who could answer my question. Here goes..
I want to propose to my girlfriend, and I want to do it in a unusual and specific way so I can actually surprise her (because she knows it's coming). This may sound like (or be) a dumb way to do it, but I before I resigned to the traditional method I wanted to at least explore a more memorable and unique approach.

My idea was to somehow replace her favorite iPhone game that she plays in the evening to unwind before bed (while her guard is down) with an app that has the same icon, but rather than loading the game, it would show her a series of 2 or 3 short messages that will basically be the set-up to me popping the question. These messages could advance one to the next with a time delay, but ideally with a button press or swipe so I know she doesn't miss it. It could also just be image files rather than text, I'm very photoshop savvy. That's really it. It would be extra cool if it were recording video from the front camera while this was happening to get her reaction but it's not absolutely crucial. I'm not sure how I'll get the phone away from her long enough to load it up and all that but I'll figure something out.

The problem is I haven't done any coding since the late 90's when I had a brief stint making a few lovely pong-esque games with Visual Basic (does that even exist still?). I don't have a lot of time either, maybe a month, so I don't know that I could learn how to pull it off in time with my day-job and all. So what I was really hoping to do was commission someone to do it. I just don't know how kosher that is to ask within SA. I pm'd one of the mods of sa-mart to ask him if that was ok for me to make a [buying] thread over there, because I know any transactions need to be contained to sa-mart, but I'm still awaiting a reply. It's an unusual request so I wanted to make sure it was within the rules. So I guess I'm asking where or how you guys think I should solicit such a service, be it sa-mart or some external place that does that kind of thing. OR, if it sounds like a simple enough thing to pull off that I could figure it out with a few tutorials despite my limited experience. I'd certainly be willing to try.

Any guidance you can offer would be much appreciated, and again forgive me if this is not appropriate in any way. I'll edit this all out if that's the case. Thanks!

Make a web page and save it as a Bookmark onto the home screen. I think you just need to set the favicon to whatever image you want, which would be the game's app icon?

Check out the Safari Web Content Guide, specifically the section where it talks about what it calls "Web Applications". It'll talk about how to set the home screen icon, the image that displays while it's loading, and how to hide the address bar and such. You'll probably need to run a lil web server on your computer and visit it on the iPhone in order for it to pick up all the icons and stuff, but that's easy to do (e.g. in Terminal, cd to the directory then run python -m SimpleHTTPServer). Set up a cache manifest (also discussed in the linked guide under "Storing Data on the Client") so it'll run without your toy web server running. You can probably snipe the other app's icon from its bundle somehow, and even its launch image if you want to keep up the ruse a few seconds longer. You can include video, do some JavaScript gesture stuff, whatever you need, it's just a webpage.

I think a month is plenty of time to bang this out. And great idea!

What is suggested by a crash log during an iOS app launch that mentions "[vm-pageshortage]" in the "reason" column for several processes? I'm on iOS 8.1.2 using an iPad 3,3. Once it started happening it was consistent when launching that app. I believe the app began launching, as the launch image disappeared and a spinner started animating, but something crashed shortly thereafter. A reboot fixed it and now I can launch the app just fine.

This isn't my app and I'm not trying to fix it or anything, I'm just curious about what might be happening behind the scenes.

The crash log isn't an app-specific one, it just lists all the processes running. Xcode lists "Process" as "Unknown" and "Type" as "Unknown" in the device logs sheet. And I dunno how relevant it is, but from the second section of the crash log:

That's a low memory log - the OS has run out of memory and had to kill a visible app to keep the system alive. When it does this, it logs out the memory usage of the system daemons and the app so you (and Apple) can see where memory was being used.

Showing up consistently while launching a specific app but then fixing itself on reboot might mean that some critical system process is using too much memory and isn't freeing it up when it's supposed to, so there's less memory available for the foreground app to use before the system runs out. That app in particular requires more than most, and it ends up going over the limit.

Clearly that's not supposed to happen.. Can you post the whole log?

Virtual memory page shortage -> couldn't allocate enough pages -> low on disk space (to page out to)? available address space? Definitely has something to do with too much memory being used or too litle being available, IMO.

Now I probably need to learn more about Views and View hierarchies but Isn't the hierarchy setup already since I added the views on loadView?
Shouldn't they be set when I try to set the constraints?

I have a feeling it's something simple that I'm messing up as I've looked at a few examples and they don't seem that different from mine. Maybe my constraint string is bad?

Here is implementation:

code:

@implementation ViewController
{
    GMSMapView *mapView_;
    GMSMarker *marker;
    UIToolbar *bar;
   
}

Here is LoadView:

code:

-(void) loadView
{
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                            longitude:151.20
                                                                 zoom:6];

    
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
    mapView_.myLocationEnabled  = YES;
    mapView_.mapType=kGMSTypeSatellite;
    mapView_.mapType=kGMSTypeHybrid;
    self.view = mapView_;
    

   
    bar=[[UIToolbar alloc] initWithFrame:CGRectMake(0,200, 500, 44) ];
    bar.translatesAutoresizingMaskIntoConstraints=NO;
    [self.view  addSubview:bar];
    
}

And here is ViewDidLoad

code:

- (void)viewDidLoad
{
     
    NSDictionary *viewsDictionary = @{@"bar":bar};
    NSArray *constraint_POS_V = [NSLayoutConstraint constraintsWithVisualFormat:@"V:[bar]-0-|"
                                                                        options:0
                                                                        metrics:nil
                                                                          views:viewsDictionary];
    
    NSArray *constraint_POS_H = [NSLayoutConstraint constraintsWithVisualFormat:@"H:|-0-[bar]-0-|"
                                                                        options:0
                                                                        metrics:nil
                                                                          views:viewsDictionary];
   
    [bar addConstraints:constraint_POS_H];
    [bar addConstraints:constraint_POS_V];
   

    NSLog(@"Finished ViewDidLoad....");
    

}

I'm just trying to get the bar to fit the bottom of the screen :3:

I think you need to add the constraints onto the mapview, not the bar. Add constraints onto the mentioned view that's topmost in the view hierarchy.

Your loadView doesn't seem to call [super loadView]. Call it at the top of your loadView.
