Hog Obituary: Jun 11, 2006; start the day right

tarepanda posted:

You one or two people to make a project from scratch, come up with art/designs, implement it all, test it, implement changes, test it, implement changes, etc., and ship in less than six months? AND on a 3,000 budget?

3000 dollars at 10/hr would get you 300 hours of work... assuming eight-hour days, you're looking at about a month and a half of work. And that's at fast food rates.

Keep in mind that once you see things, you're probably going to want changes or perhaps you'll have new ideas or perhaps some things won't be feasible for whatever reasons.

Plus sounds and whatever else you might want for your game that people will have to make or come up with.

I've been doing a project for work on my lonesome, pulling 70-80-hour weeks... and we don't even have (many) custom graphics assets... and after three months, I have something I'm happy with calling a "beta" version. It's a pretty complex thing though. :x

I would bet the guy who quoted 6 months probably has a bunch of other projects in progress at the same time. Nobody (worthwhile) is going to do 6 months of dev work full time for $3k.

Very true.

$3k would account for around a week and a half of my time if we just straight divide my salary by the number of weeks in a year...

Is there a parent class for all (or most) UI items?

I want to reposition a lot of things on the screen programmatically (through frame and setTransform), so I was hoping to just stick them into an array and iterate through it. The problem is that I can't just use id for the current object since it doesn't have a frame...

The array would include UILabels, UITextFields, and UISteppers... which all have frame and setTransform.

Am I way off in left field here?

You can't use .frame on an id, but you can send it the frame message, which is what .frame does. So it should work.

If you're just setting a property then dot notation is fine. It's when people try to use dot notation for non-getter/setter methods that they've gone too far. Just so long as you understand that the compiler is just translating someObject.frame = whatever; into [someObject setFrame:whatever];.

Also, to the best of my knowledge, all the UI elements on iOS are descended from UIView.

DreadCthulhu: Sep 17, 2008; What the fuck is up, Denny's?!

Hey guys, what's the most kosher way of storing hundreds of rather tiny (5-30kB) pictures and audio files that might need to be displayed to the user at some point. Think of a language learning tool where you play a sound / display an image in addition to showing the text.

My gut feel is, for simplicity sake, to just store everything in the bundle and fetch it directly from disk on demand, although that likely adds a 2-5ms delay for both the audio file and the picture itself, which may or may not result is a nasty user experience. Has anybody tried this approach before and found the results to be good?

The other option is to dump the images/audio files into CoreData during the first app boot (downside is now you have the same data persisted twice on the device) but now you can use the trick where you warm the CoreData cache in a background thread and thus make the data available at memory-speeds. The downside is having to keep CD in sync with the bundle as the app evolves and the additional complexity of cache preparation.

Thoughts?

Okay, wow. Rotating a UIStepper is harder than I thought it would be.

First of all, if you just setTransform, it doesn't actually rotate the entire stepper, it rotates the contents of... the view (?) giving you a clipped stepper. If you turn off "clip subviews," it rotates the stepper properly, but the touch-sensitive areas aren't rotated (???).

Does anyone have experience with this? :x

Where are you getting your 2-5ms number? At 30fps that's 1/15th-1/6th of a frame and would be imperceptible to anyone. I suspect the actual amount of time it takes to load a 30KB resource from flash storage is much, much higher.

That point notwithstanding when I develop apps my rule of thumb is to do the simplest, most understandable thing first. If it results in a bad user experience I'll go and optimize where I need to. Balancing productivity and user experience is always the tradeoff as a developer, unless you have unlimited resources. If you still opt to front-load optimization I think Gordon Cole's method is the way to go. Figure out what assets you'll need to display during the sequence you're going to show the user and preload them. Core Data adds a decent amount of development overhead and it really feels like you're trying to fit a square peg into a round hole by using it to store binary assets that you already have on disk.

Can you customize the message/buttons that show up when your app is requesting permission to access something in the phone (contacts, etc.). I'd like to change the standard "YourApp is requesting permission to access blah". Currently using this code:

code:

ABAddressBookRef addressBook = ABAddressBookCreate();
    
    if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
            // First time access has been granted
            [self parseContacts:addressBook];
        });
    }
    else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
        // The user has previously given access
        [self parseContacts:addressBook];
    }
    else {
        // The user has previously denied access
        // Send an alert telling user to change privacy setting in settings app
        UIAlertView *alert = [[UIAlertView alloc] 
initWithTitle:@"Error" message:@"Please add to privacy settings" 
delegate:self cancelButtonTitle:nil otherButtonTitles:nil, nil];
        [alert show];

That's what I told my designer, but he insisted that he'd seen other apps do it. Maybe they had been doing their own sort of confirmations without using the real method for requesting permission.

Hughlander: May 11, 2005

It's too early in the morning for me to think, but I thought that one of the functions had an argument where you could add the 'reason' for the request. Obviously it's not ABAddressBookRequestAccessWithCompletion though.

Anyone know how to get the simulator to require privacy access? For some reason, there are no apps listed as being able to access contacts in the simulator, so I can't reset privacy settings. I even completely reset the simulator and settings, but the simulator still assumes I have access to everything.

You'll have to use a device. Only CoreLocation prompts work on the simulator.

You don't need to subclass UIBezierPath to do this; you can just add your wacky methods in a category on UIBezierPath. Then they'll be available on all instances of the class, not just instances of your subclass. (Unless your wacky methods also require you add instance variables. But you can work around that using associated objects.)

I suspect the senior developer wasn't saying "I'll do this over the course of six months for CDN$3K." Rather I think the senior developer's message was really "what you're asking for is about six months' work," implying "and not something you'll get for that pittance."

Six months of full-time work is a plenty realistic estimate for a real game created by an experienced developer.

Yeah I have both a personal (free) account and a paid company account and it just asks which I'd like to use when I log in. It's pretty good even though I wish it would just give me access to all the assets I have available to me at any given time. Oh well.

Also apparently Apple stopped recognizing a Sole Proprietorship as an actual corporation like a week before I decided to get a paid developer account (a few years ago) :suicide:

Speaking of ScrollViews, I need to make an EPG style component. It will only have a few channels vertically (less than 10, with most of those being sparsely populated rather than 24 hours of broadcast) but needs to scroll horizontally for a week into the future. What's the best way to do this? I guess I could either make a huge scroll view and pre-populate it with all 7 days worth of programmes (if that won't cause performance issues), or copy the TableView and make up a showEntryAtTime/dequeueReusableShowEntry design pattern, regenerating the entries as the user scrolls around.

I've also (for a separate purpose) been having trouble trying to work out which page index a pagingEnabled ScrollView will snap to when the user stops interacting with it. There's the scrollViewWillEndDragging:withVelocity:targetContentOffset: delegate function which seems perfect, but it doesn't get called for paging ScrollViews. I've tried to hack around it by storing the contentOffset in scrollViewWillBeginDecelerating and checking which direction it's moved in the next call to scrollViewDidScroll, but it still seems to get tricked sometimes (and it feels dirty).

Are Bezier Path objects meant to be animated? I'm basically attempting to create a shaped progress bar with bezier paths, and while it works, it's done by redrawing the entire path with each increment. This seems way less efficient than extending an existing path, but this doesn't seem possible. Should I just be adding new points to a filled path and then refilling it?

It's really no big deal, especially if the app isn't overly complex. Just make sure you've tested it properly before you submit it and you shouldn't have a problem. They aren't looking to spend hours and hours making sure there are no bugs -- they just want to make sure it isn't going to crash in the most common of circumstances. If you're really concerned, there's a way to test the AppStore build on a development device, but personally speaking I've never found that to be necessary. Just deleting the development version completely and reinstalling it before testing should be enough.

At worst, they reject it, tell you what to fix, and you do it all over again. They don't fine you, or send hired goons to your house or place of business to beat you up, and they've only ever caught bugs that would've seriously hosed my app had it been released, so when you get down to it, they're reasonably helpful. They've failed to find, both in my apps and (clearly) others, many embarrassing bugs.

Realistically, as long as you've followed Apple's clearly-stated rules and submit them a bug-free product, it's going to get through no problem.

I was under the impression you don't need to seek export permission if you're using the built-in crypto libraries (including SSL), since Apple has already gone ahead and gotten export permission for those.

Otherwise there are thousands and thousands of apps in violation: every app that uses Facebook's SDK, an OAuth library, Flurry, etc.
