Thanks, that looks like it's worth checking out. The only problem there is that it requires iTunes to view the lectures, while I only have Android devices, and I don't like the idea of installing iTunes just to watch the lectures. Oh well.

I'd love to hear book recommendations too, it's usually easier for me to follow along with something printed than with a video or audio.

Me too but so far I haven't seen anything good book wise... It might exist, I just don't know of any.

Just install iTunes for windows in a VM. The actual videos are (IIRC) h264.

You kinda need a Mac (or at least OS X in a VM) for iOS dev.

I didn't bother watching most of the videos; the slides and homework assignments were enough most of the time.

I hosed up and accidentally deleted /usr/local/include on my Mavericks installation (don't ask how that happened please, it's shameful).

I seem to recall there being some system-default headers in there? What would be the most appropriate way to restore the file structure to the way apple intended it to be?

No.

Storm Sim has a dark theme (people use it to fall asleep; no one wants to be blinded). I am discovering that doing anything other than the default white is a huge pain in the rear end. I'm now up to fighting the popovers. My background tableview is black. The popover now has no border because it just wants to dim the background, which it can't do on a black background. Is there an easy way to add a border like every other view? Nope.

Have you run into this? If you use a navigation controller in a popover, there is a weird gradient that appears at the bottom of the popover the second time you pop it open. Here's the app I submitted to the Bug Reporter:

https://pantherfile.uwm.edu/kdschlei/public/GhostlyImage.zip

Of course, it's not noticeable if you use the default light background, and why would anyone not use the default? Everyone wants a bright white popover! EVERYONE!!!

I'm looking forward to that issue; currently I'm trying to figure out how I can get the popover not to blend into the background view.

My favorite iOS 7 WTF is if you present a UIDocumentInteractionController from a view controller that was presented modally (but only as UIModalPresentationPageSheet or UIModalPresentationFormSheet, the other non-sheet styles work just dandy).

It comes up fine, but when the document interaction controller is dismissed, it also tears off the view from the modal view controller that presented it. You just get left with the shadow view that was behind the modal, so the app is unusable beyond that point. The best thing I could come up with to work around was to temporarily dismiss the modal view controller but hang onto a reference, present the UIDocumentInteractionController from the modal's parent, and then re-present the modal upon dismissal.

They did nothing with the radar I filed three months ago, but at least it looks like it's been fixed in 7.1, thankfully.

Has anyone ever looked at the memory footprint of the various JSON deserializers? I've got some really oddly organized legacy documents that with RapidJSON just seem to balloon incredibly. (One JSON file ~100k in size that contains 1700 NSDictionary sub tree/values. If I was reading that correctly it was almost 6 megs in memory size. Though the more I think about it the more I doubt the number and will need to look at it closer.

I've always traded speed for anything else when it came to JSON but now that I'm using Mik Ash's future libraries I'm starting to think that I'd rather trade memory for anything else.

I spent about 3 hours today trying to hunt down a bug in my collection view logic. It didn't happen on the iOS7 sim, the iOS6 sim or the iOS6 device. It did happen on the iOS7 device. I was literally banging my head on my desk until I realised it was due a wacky thing that only happened when using a distribution profile to build for the iOS7 device. :doh:

LP0 ON FIRE: Jan 25, 2006; _{beep boop}

In iOS 6 I had drawing text as fills and strokes, so I could have outlined text, working fine. Still works in iOS 7, but it's deprecated.

code:

//draw fill on top of stroke
    CGContextSetRGBFillColor(context, 1.0, 1.0, 1.0, 1.0);
    CGContextSetTextDrawingMode(context, kCGTextFill);
    CGContextSaveGState(context);
    [text drawAtPoint:CGPointMake(2,0) withFont:font];

So I changed it to this:

code:

NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
	
NSDictionary *attributes = @{ NSFontAttributeName: font,
					      NSParagraphStyleAttributeName: paragraphStyle };

//draw fill on top of stroke
    CGContextSetRGBFillColor(context, 1.0, 1.0, 1.0, 1.0);
    CGContextSetTextDrawingMode(context, kCGTextFill);
    CGContextSaveGState(context);
    [text drawAtPoint:CGPointMake(2,0) withAttributes:attributes];

But now I don't see the filled text. What am I doing wrong here?

# ? Dec 12, 2013 20:38

dizzywhip: Dec 23, 2005

Not sure how those CG functions work, but my guess is that they don't apply when drawing text with attributes. The text color is determined by NSForegroundColorAttributeName, and the default is black. I'm guessing it's not showing up because you're drawing on a black background. Just add that attribute and get rid of the fill color / drawing mode CG functions and you should be good.

I'm a novice ObjC coder, so I apologise if I get the nomenclature wrong.

Does anyone have a decent tutorial of how to filter keys of a plist into an array? I'm looking to build a Table with the names of each item. Currently, each item has keys set up for name, summary, and image. So what I'm hoping to build an array with name1, name2, name3... etc.

I should add, the plist is an array that contains dictionaries.

Sorry if this is a rookie question. I will edit this post if I find what I'm needing.

I assume your plist is just an array of items, each item having the 3 key-value pairs?

NSArray *plistArray = [NSArray arrayWithContentsOfFile:file];

Now you can just do something like

code:

for (NSDictionary *dictionary in plistArray) {
    //do something here with [dictionary objectForKey:@"name"];
}

Thanks for that.

However, I just discovered it's an array with dictionaries for the various items. You can see the structure at the place I stole it from - http://www.raywenderlich.com/12444/objectively-speaking-a-crash-course-in-objective-c (search for 'Property Lists Rule!', and it should be below that).

Here's a screenshot of the Property List in my app (repeating for item 1, item 2, etc):

That tutorial also made use of NSBundle to load the plist, but I noticed that you can achieve that with NSArray directly?

EDIT - I misread your script. Apparently having dictionaries is fine for the code you've written?

Right, so the code I posted above would work. When I said "I assume your plist is just an array of items, each item having the 3 key-value pairs?" what I really meant was "I assume your plist is just an array of NSDictionary objects", since an NSDictionary is just a key-value association. The use of NSBundle is to find your .plist file inside the application bundle.

I think this code would accomplish what you want:

code:

NSString *file= [[NSBundle mainBundle] pathForResource:@"someFileName" ofType:@"plist"];
NSArray *plistArray = [NSArray arrayWithContentsOfFile:file];

for (NSDictionary *dictionary in plistArray) {
    NSLog(@"%@",[dictionary objectForKey:@"name");
}

That would just print each "name" item to the console. The for loop just takes your plistArray object and reads each item as an NSDictionary. If you had an array of some other object type, say NSString, you could do something similar: for (NSString *string in someArray) { ... }

Here's a quick tutorial on it: http://iosdevelopertips.com/objective-c/fast-enumeration-on-the-iphone.html
