iOS7 compatibility

hcabral

I noticed that the UI is much more responsive in an iPhone 4S. Maybe they are "leaking" UIKit memory Firefox-style in order to gain performance in some cases?

Cheers,

It has been fixed in Beta 5!
Well at least for Sparrow games. all touches are ok

BUT there's a strange warning on each touch action:

AssertMacros: queueEntry, file: /SourceCache/IOKitUser/IOKitUser-920.1.11/hid.subproj/IOHIDEventQueue.c, line: 512

and I still can see a lot of broken UIKIT apps prepared for ios6.

Daniel

Thanks for testing that, Dro! It really shows that they changed a lot of internal stuff for iOS 7, that these betas are causing so many problems ... well, at least it seems to be getting better now. 😉

Anyone could reproduce the blackscreen by opening an old game made with sparrow on ios7? I'm not sure if you guys only reproduced this by compiling on xcode5.

I installed a game made for ios6 via testflight on ios7 and got the blackscreen, right after the splashscreen.

(I can still hear the music and sound effects)

Daniel

Have you tried using the latest head revision of Sparrow? There are still problems with the simulator (the colors are all off), but afaik, it should work fine on an actual device.

epa_neto

It worked Daniel, thanks 😉 Also the status bar solution, thanks mnem.

The only thing I still could not solve, is that one of my spritesheets shows up very strange, but It's something I will wait for the next beta or release version.

Hmm Daniel, actually the problem happens on ios6 now (using the last edited version of sparrow). Check this image:

The player is that big white "pixelized" ball. It happens that before, I could see its art. The only difference between the player and the other balls,is that the player uses only a SPImage, and the others, animations.

The player is initialized like this:

_image = [[SPImage alloc] initWithContentsOfFile:@"avatar.png"];

And the target balls are initialized like this:

_frames = [Media atlasTexturesWithPrefix:textureName];
_animation = [[SPMovieClip alloc] initWithFrames:_frames fps:30];

Maybe I should just let this go until the final release of ios7 and stick to the stable version of sparrow?

All the best,
Epa

@epa_neto I had a similar issue. I think it has to do with the way the png is encoded.

Two things worked for me, resaved the png, make sure it is a PNG24 and not PNG8. Photoshop's save for web should give you a correctly encoded png.

Or, implement Daniel's SPTexture changes earlier in this thread.

I tried the latest (bleeding-edge) Sparrow from Github with XCode 5 GM.
I ran the Scaffold project with the simulator and all I get is a black screen and the console prints "There was an OpenGL error: 0x502".

So are there still iOS7 issues or am I doing something wrong?

Daniel

Are you sure you're using the latest version from the "master" (!!!) tree?

I'm currently testing the GM seed as well, and it seems to work fine, so far! Especially a nasty color error has been fixed -- I had hoped they'd do that for the final version. =)

Daniel

The only problem I'm still facing is that the unit tests don't run through in the 64 bit version. For some reason, Xcode doesn't tell me exactly *where* it fails, though *g*. But I'll find that.

In any case, once the 64 bit stuff is settled, I'll make a "Sparrow 2.0.1" release that contains all the iOS 7 compatibility changes.

Hi Daniel,
you are right, I think my sparrow source tree path was still pointing to the wrong version. I downloaded sparrow 2 again with the newest changes you made and now it works.

Daniel

Perfect! Thanks for the update! 🙂

Hi there! I just wanted to document changes I had to make to my app to make it compatible with iOS7.

opengl issue:
I received the "There was an opengl error: 0x502" message when running the app, built as an iOS6 app, on iOS7. It gave me the same error even _after_ compiling w/ Xcode5. That issue was fixed after downloading the latest changes from the master branch.

PNG issue:
Also, I can verify that the code below, when applied to Classes/Textures/SPTexture.m at around line 272, fixes the issue where my alpha PNGs (which are part of my game's main texture atlas) were displaying as pixelated opaque images. Great Work!

+ (NSDictionary *)optionsForPath:(NSString *)path mipmaps:(BOOL)mipmaps pma:(BOOL)pma
{
    // ... code above

    #if TARGET_IPHONE_SIMULATOR
        // ... don't change
    #else
    NSString *osVersion = [[UIDevice currentDevice] systemVersion];
    if ([osVersion isEqualToString:@"7.0"])
    {
        BOOL usePma = pma && [self expectedPmaValueForFile:path];
        [options setValue:@(usePma) forKey:GLKTextureLoaderApplyPremultiplication];
    }
    #endif

FYI, it wasn't immediately obvious to me where to put the status bar hack. I ended up putting the code:

- (BOOL)prefersStatusBarHidden
{
    return YES;
}

in the SPViewController.m file.

It would be great if you added an option to "Review" a post before posting it! I've had to edit this post a few times because my grammar sucks 🙂

Thank you PeqNP.

I have confirmed that the UIStatusBarHidden and UIStatusBarHidden_ipad values no longer work for any application running in iOS 7.

Using "prefersStatusBarHidden", as PeqNP suggested, works. If you still prefer to use the plist values, you can do this:

@implementation SPViewController (StatusBar)

- (BOOL)prefersStatusBarHidden
{
    return ((NSNumber *)[NSBundle mainBundle].infoDictionary[@"UIStatusBarHidden"]).boolValue;
}

@end

for status bar there's a new field on App-Info.plist

View controller-based status bar appearance - NO

Shilo

I could have sworn I tried that. "View controller-based status bar appearance" does work fine. Thank you.

Daniel

So, to summarize: when you use the very latest Sparrow version from the master branch, it works perfect in the simulator -- but on a real iOS 7 device, you have to add that PMA change from PeqNP's post, right?

(I still don't have a real iOS 7 device at hand.)

If somebody can confirm this, I'll add that change to the core -- and Sparrow will be perfectly valid on iOS 7.

Daniel

I added that change to the Master branch now. So with the latest version, everything should work fine on an actual iOS 7 device.

If anybody could confirm that, it would be great! 🙂

Dro

I can confirm that.
Yes previously we had to mod SPTexture.m
now it's ok
