I just wanted to ask why my app is starting with a too small size on devices other than iPhone 4s on my simulator? Is there something wrong related to the constraints I set or general project difficulties?
You must set your launch images. At least set them for iphone 6 and you should solve the issue

In iOS7 Text Magnifier isn't working app wide
(5 answers)
Closed 9 years ago.
I'm working on an iOS 6 app that's needs to be compatible with iOS 7. For some strange reason whenever I deploy the app on an iOS 7 device, if I try to magnify text, the magnifier is blank.
Here's a screenshot of the issue
Thanks in advance!
This happens when there are multiple UIWindows in the .xib. At least that was the problem for me. I was using a UIWindow for VGA output. As soon as I deleted the window from the .xib my cursor worked. I then recreated the UIWindow in code.

How to configure iOS app to work on specific devices?
(3 answers)
Closed 9 years ago.
How can I set up my iOS project to run only on iPhone 5, iPhone 4S, iPhone 4, and all iPads except the iPad 1? I am committing to iOS 6 only.
I wanted to answer this in a comment but I cannot still comment everwhere. :D
Take a loook at this : How to configure iOS app to work on specific devices?
By setting Deployment Target to iOS 6, you exclude iPad 1 and any iPhone older than 3GS. Not sure about iPods, but you didn't mention them.
Since iOS 6 runs on iPhone 3GS and you don't want to support it, you need to have reason. Tell us and there may be solution.
Edit: So if the main reason is non-retina display, you can't do much. You are not alone, who would prefer all devices to be retina-capable, but unfortunately… But hey, all retina graphics just works on these devices without a problem, so just leave it like that. Users of those devices know they have poor display.

Why is glReadPixels() failing in this code in iOS 6.0?
We're trying to take a snapshot of OpenGL ES view and to save the result in a UIImage.
For iOS 5.x our function works well.
For iOS 6 our function works only on the simulator and not on the device. We receive a blank (white) image on the device.
We referred to the technical report at http://developer.apple.com/library/ios/#qa/qa1704/_index.html
and our function is almost identical to the function presented by apple in this technical report
Enclosed below is our function (in the Additional Details window).
We would be grateful to receive an assistance and we hope to have a reply as soon as possible since our app is currently online with this critical bug.
(BTW, we use only opengl es and not cocos2d)
PLEASE HELP.
In case you didn't get an answer on this: As documented in some other posts, I found that this only affected devices and not the emulator running my app. I set CAEAGLLayer drawableProperties when initializing with kEAGLDrawablePropertyRetainedBacking set true. Haven't noticed a huge hit in speed and my captures are working again.
