I have an iPhone app that runs fine on iPhones (tested on iOS 6 and iOS 5), and iPads running iOS 5. However, on an iOS 6 iPad, the app is initially unresponsive until resized from 1x to 2x mode (or vice versa), or an orientation change.
This appears to be a bug in the Operating System, since an app isn't supposed to be able to react to changes to the 1x or 2x mode, but it's still baffling. Any ideas?
I also see this issue on my apps. I found a solution: In the Xcode project -> Targets -> Summary, scroll down to 'Status Bar', check the box for 'Visibility' 'Hide during application launch'. After doing this, the iPhone app works again on iPad iOS 6.
You may notice that after the change the status bar is hidden. You can re-enable it in code with:
[application setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
PaiGow's fix worked for me, but in the iPad Retina sim with iOS 6, views pinned to the top edge of my (Landscape-only) screen moved up into status bar space and were cropped by the dummy status bar than the iPhone "display" on iPad uses.
Instead, I left "Hide during application launch" UNchecked, but still used the line:
[application setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
in my app delegate's applicationDidBecomeActive call.
Just making this call to setStatusBarHidden:withAnimation: is enough to make the app responsive again, in both the sim and on an actual device, and it has no visual side effects that I can see.
I've also tried putting the call in application:didFinishLaunchingWithOptions: and it works in the sim; haven't heard back from my beta tester with the iPad yet as to whether it works just as well in hardware.

We have an app that has been rejected in the review process by the Apple app review people. The cause for the rejection is that the app is not scaling properly when run on an Ipad.
The app was never meant to be run on an Ipad, but there seems to be no point in arguing with them about that.
Apple sent us a couple of screenshots that show our app being run on an Ipad with the top portion of the view cut off. Notice how the app is run in some mode where it looks like an Iphone app and does not fill out the entire display area. When we bring up the app on an Ipad, it fills out the screen and does so without any edges cut off.
Can anyone please tell me how to run the app on an Ipad the way the Apple guys have - Iphone-sized? We believe we have a fix for the issue but we need to reproduce the error and then be able to verify that the fix solves the issue.

I just went through this myself and here is how I resolved it:
Go into info.plist and see if any of the supported interface orientations are set for iPad. Despite selecting iPhone only, I had iPad supported orientations for four (portrait, portrait upside down, landscape left, landscape right). I deleted those.
I also deleted any reference to the launch screen in the info.plist. My app is pretty simple and there's no preloading of data so I don't really need a launch screen. If you do, you could go old school and make your first VC the launch screen.
I then made these changes in Target-->General-->App Icons and Launch Images
That was the only way I could get it in the sim to run the app at iPhone resolution while running an iPad (iPad2, iPad Air).
If Apple is going to force developers to ensure an app runs on an iPad even if it is made just for iPhone, they should eliminate the iPhone Only and Universal options and just have iPad Only as an option.
To run an iPhone app on an iPad, you just need to:
Acquire an iPad (you can also use the simulator)
Set the target device family in Xcode (it's under your target) to iPhone
Connect your iPad, perform any necessary certificate dances
Run the app on the iPad.
As long as the target device family is set to iPhone, the iPad will show your app in this mode.
Apple is likely running your app on a simulator, not on a real device. Notice the "2X" on the top right. In XCode - you should run the app on iPad Retina Simulator. On the bottom right you will see a button that you can toggle from 1X to 2X.
If you place the simulator in "2X" mode, you will see what Apple is seeing.
What OS are you running on your iPad? Things have changed in iOS 8 - and that's likely why you're not seeing what Apple is seeing. My guess is that your are running an app that was initially developed for iOS 7 or earlier - which means that you need to upgrade from scaled resolution to native resolutions to resolve this issue. Here is how you do it:
How to enable native resolution for apps on iPhone 6 and 6 Plus?
I have an application in iphone market which works for iPhone 4s and lower version. So now iPhone 5 has been launched which bigger size screen, my question is what all changes i have to do in my application so that it will be compatible with iPhone 5 also.
1) Do i have to rebuild my app for iPhone 5?
2) Do i have to make changes only in UI ?
3) Will the iPhone 5 will its make it compatible?
Your valuable replies will help me a lot. Thanks in advance.
Here is my answers,
1) Do i have to rebuild my app for iPhone 5?
If you want to utilize the complete screen space, you can add Default-568h#2x.png and rebuild the app and release it.
2) Do i have to make changes only in UI ?
You can utilize the complete screen space for iphone 5. You can code for screen modifications in case of other iPhones.
3) Will the iPhone 5 will its make it compatible?
Yes. It will make it automatically compatible. It will add a black strip on top and bottom to compensate for the extra space in the screen unless you add Default-568h#2x.png.
If your app uses the standard UIKit provided by Apple, you only need to add a 4 inch launch image to your app, and it will automatically resized itself. But if your app using custom controls or graphics-heavy like in games, you might want to adjust the images and take advantage of the larger screen.
You also have to make sure the methods you used do not deprecated on iOS6 to prevent the app from crashing. Some references if you need further reading.
To make older app compatible with iPhone 5 You need to look for Following things.
Latest Xcode version 4.5.
Open your project and select Upgrade settings for new version.
Add Default-568h#2x.png for new resolution .
For UI you have to change your xib's object autoresizing property.When you select View Go to
inspector and select size property It will show you None, Full Screen, Retina 4 options . Set autoresize property for all your Buttons , labels and check xib for retina 4 and None both.It is same like you set it for Landscape and portrait .
5.Some other changed will be in code because some method has been depreciated for ios 6.0.
6. After doing all this .You can run it on iphone 5 simulator for testing.
I have an app that was using GLKMatrix3 and its supporting functions. I found that the GLKMatrix3Multiply function would always crash on iPhone 5 hardware. Easy to workaround using GLKMatrix4 instead, but the point is that I would never have found the problem without actually trying my app on iPhone 5 hardware.
I was told to file a bug for the GLKMatrix3 problem, so maybe this will be fixed. But the code runs just fine in the iOS 6 simulator.
I learned from this that, whether or not you need to rebuild your app for iPhone 5, you do need to at least run your app on a device before advertising support for that device.
I've got a very strange behavior in my iPhone app.
The app should run in any orientation. Plist keys are all set and shouldAutorotateToInterfaceOrientation always returns YES.
Also, it's an iPhone only app, but at this moment I can test it only on the iPad.
Now, when I start it in portrait mode, everything works fine. However, if it launches in landscape mode, the view doesn't receive any touch input, buttons and gestures simply don't work. This is happening as long as the window remains unaltered. If I rotate the app and then rotate it back to landscape, it works. Moreover, if I press the "2x" button on the iPad, the app also starts to work normally.
I've checked all view frames and everything is drawn correctly.
When run in simulator, it ignores the initial orientation and draws itself in portrait mode.
What can be the reason and how to solve it?
I have found that this is unique to iOS 6 (you'll see this on iPads running iOS 6 and even the iOS 6 iPad simulator, but not devices/simulator running iOS 5). If you remove all of the entries under "Supported interface orientation" in the app's plist, this problem seems to go away. Alternatively, if you check the "Hide during application launch" option for the "Status Bar" settings on the Summary screen of the Target settings, this also fixes it:
It makes no sense why either of these should fix the bug, but they appear to.
If you use the "Supported Orientations" tweak, in iOS 6, you can still programmatically control the permitted interface orientations via supportedInterfaceOrientations (in iOS 5, you can still useshouldAutorotateToInterfaceOrientation:).
Hey i am developing an app for iphone5 (4 inch screen) everything works fine but when i run my app on iOS 5.0 and rotate to landscape mode , keyboard does not fit entire screen ,
Adding a screenshot. it happens with all keyboard type.
Is there a way to deal with this bug at our end or it needs to be fixed by apple guys only.
I am running app on simulator, so if anybody have iphone 5 with ios 5.0 installed , please check, Does that issue persists on device also ?
I'm making an app for the iPad with TV output to an extra screen. Everything works fine, but for some reason the TV out window disappears when I put the iPad in landscape mode. I commented all the code that makes it go to landscape automatically but as soon as I rotate in iPhone simulator, the tv output window goes away.
Is it just not possible to have the device in landscape mode with an extra screen or is there something I'm overlooking?
Thanks in advance.
I've noticed there's a CALayer use-after-release bug in iOS7.0.3 simulator when you have setup an External Screen triggering at some point, but a later iOS7.1 fixes that. Can you confirm if you have the problem with iOS 7.1 ?
