iOS7 compatibility

Hi!

Has anyone already tried to run sparrow projects on the new iOS7 (7.0 SDK)?

I've found, that my sparrow project, which works on 6.1, produced Open GL Errors 0x502 when I started it in the new iOS 7 simulator.

In addition I just downloaded the new sparrow game Hookshot from the App Store (mentioned here in the forum) and wasn't able to get it working on my iOS7 iphone.

Has anyone experienced the same issues, or was able to port his/her sparrow project to 7.0 SDK without any problem?

Thanks in advance,
max

Hi,

I haven't got any iOS7 stuff set up yet, but I'd be interested to see if any games written in other engines (such as cocos2d) are broken too?

And if Sparrow 1.x works but Sparrow 2.x doesn't?

etc 🙂

Daniel

I haven't installed iOS 7 yet -- I'd also be interested in the results!

For a Sparrow 1.0 game, could you try Find it! 2?

I remember that there were problems with the first beta of a new SDK version in the past already; they were always sorted out later. So I'm tempted to just wait for the next beta. 😉

However, it depends on how many apps have problems. If recent Cocos2D games run fine, and only Sparrow has problems, I should definitely review the problems and see if I can do anything about them.

I have tried running my, already compiled apps, running sparrow 1.3, and they ran fine. Except for one but I think that is another issue with the sound engine. Will have to check that out at some point.

But as Daniel said, I also remember there are usually problems with he first beta, that magically gets fixed later usually. So, I should not and will not worry about it yet. 🙂

Find It! 2 runs without any problems;
and so does Star Trek Rivals, which i already had on my iphone - however, i'm not quite sure about the sparrow version, Rivals is using.

Thanks, ERik, that's good to know!

Max, Star Trek Rivals uses a modified 1.4 version, as far as I know. Since Hookshot uses version 2, it seems like an OpenGL ES 2.0 change or bug in the new iOS version. Still, I'd wait for the next beta release before getting nervous.

Or does it prevent you from doing any development? You can still use the simulator with iOS 6, right?

Hi Daniel!
Nice of you to ask, but Xcode4+AppCode+iOS6+Sparrow2 still work like a charm 🙂

Perfect! =)

Same here. a problem with 7b.

debug: black screen and constantly appearing log: There was an OpenGL error: 0x502. The game is actually working inside. Even sprite and touchh based things.
release: crash. not determined correctly yet. But I can hear the music before that. TF cound not catch it. Probably the same problem from debug.

Repeats for Sparrow Demo. Same for simulator ios7.

After all. Xcode5dp show some extra warnings:

everything's ok if I compile with Xcode5dp for ios6 though..

pandaboy written with 1.3 works on ios7 fine.

when i try to build sparrow 2 with xcode 5 for ios 7, all i get its a black screen.. but so far all prebuilt apps for ios 6 works with ios 7, must be something with the new sdk

Dro

not like that here. Prebuilt sparrow 2.0 apps do not work on ios7.
Deployment target for my app is 5.0.1 actually.

as I can see all sparrow 2 projects work only on ios5-ios6.

Daniel

As I said, I'm sure the problem will go away with one of the next iOS 7 betas -- must be an SDK problem. However, I'll see if there's a quick fix for you guys.

Daniel

I tried it myself and can reproduce the problem. However, I'm sure I'm not doing anything wrong. The error occurs when I pass the transformation matrix to the vertex shader; all data is correct, though; and it works just fine in iOS 6.

So it's definitely an iOS 7 bug. I'll wait for the next beta, and if that doesn't change anything, I'll try to contact Apple about it.

IOS 7 beta 2 installed.
There was an OpenGL error: 0x502

but there's a small green rectangle on top right corner. Don't know if it means anything.
also UIKit layer is totally visible.

Damn. 🙁
No idea where that rectangle comes from!

I'll investigate.

Tested my apps on ios7 beta 2. Running Sparrow 1.4.

Everything seems to work fine, except that the status bar on top is now visible even though it is supposed to be hidden... I think I might wait for beta 3 before I try to fix it 🙂

Hmm.. I also have OpenGL error: 0x502 and everything is just black

Just playing around with this at the moment. It seems to break if it's rendering anything that's textured - if you drop the

texture2D(uTexture, vTexCoords)

bit in the fragment shader and replace it with a solid colour it shows the textured thing as a solid colour.

Seems pretty likely that it's something broken in the beta, but at least it's consistently broken between the simulator and the device 🙂

mnem

Out of interest I tried a minimal Cocos2D 2 build, and that seems to work with pretty much the same shader code so it's pretty unlikely to be that after all.

Instruments can probably help you out with the 0x502 code, I just had one which was down to using glEnableClientState calls, instruments told me the problem calls, fixed them and it went away, so might be worth running via that to see exactly where the problem lie.
