In the app that not optimized for iphone 6 in standard display mode keyboard and status bar shows zoomed. This causes my manually layouted custom keyboard extension to show streched. How can I detect this zooming to fix layout?
Use self.view.frame.size.width It returns 320 for zoomed mode & 414 for regular mode on my 6+ (hopefully on 6 also) in - (void)updateViewConstraints
Eventually you will not need to do this as whatsapp and other apps get updated (I believe whatsapp just did) but how I get around it temporarily is by getting the size of the view where I am drawing my keyboard view.
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;
The iPhone 6 and 6+ will tell you that your screen width 320 for portrait and 568 landscape like an iPhone 5. You can then use the same drawing you do for the iPhone 5.
When the app is optimized for the iPhone 6 and 6+ you will get their real measurements.
Something I don't get is why people are downvoting my answer when it is the right one. We had to specifically deal with this problem. When the app where your extension runs is not optimized for iPhone 6 the dimensions are the same as the previous iPhone and the app is scaled up to full screen. Just run in an iPhone 6 an old app that was never updated and see it for yourself.
since iOS 8 my App runs quite good, but I found a Problem while testing this app.
It just happens on iPad and only if I launch the app in landscape mode. If it launches in Portrait everything is right(no rotation issues). If i rotate the Device (simulator or real device) the view rotates out of the screen and just shows a Cut of the real view and the rest is black.
Anyone else did notice such a bug? How can I fix it?
Had similar problem. Surprisingly the fix was to comment out all the code related to self.window on Appdelegate.
Commented initialising of self.window and its assignment. Set the initial view in storyboard in Attributes inspector by checking "Is Initial View Controller" checkbox.
New Better Solution
Commenting self.window was causing other issues. Instead the below code is best:
- (void)applicationDidChangeStatusBarOrientation:(NSNotification *)notification
{
[UIViewController attemptRotationToDeviceOrientation];
}
UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
BOOL landscape = (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight);
NSLog(#"Currently landscape: %#, width: %.2f, height: %.2f",
(landscape ? #"Yes" : #"No"),
[[UIScreen mainScreen] bounds].size.width,
[[UIScreen mainScreen] bounds].size.height);
And the results are:
For iOS 8+
Currently landscape: No, width: 320.00, height: 568.00
Currently landscape: Yes, width: 568.00, height: 320.00
and for iOS 7-
Currently landscape: No, width: 320.00, height: 568.00
Currently landscape: Yes, width: 320.00, height: 568.00
It seems like there is a change in the way height and width of the screen is handled while in portrait and landscape from ios8 onwards.

Is [UIScreen mainScreen].bounds.size becoming orientation-dependent in iOS8?
UPDATE - We found a fix:
I found the answer to our problem which as described below appeared to be exactly the same as yours. One of our other developers noticed an "unexpected nil in main window" when attempting to tap on the far right of the screen. This led me to do a new search and I found this thread on stackoverflow that actually contained the answer to our problem.
( here is the link to the question which help my answer: unexpected nil window in _UIApplicationHandleEventFromQueueEvent )
The actual answer came from frankish who suggested opening the main.xib (or main storyboard) and clicking on the Window in that and making sure that the "Visible at Launch" and "Full screen at Launch" properties are checked (set to true.)
In our case, it was JUST the "Full screen at Launch" property that needed to be set, but setting this fixed the rotation problem we were seeing AND it fixed an issue where when launching on iPad in landscape the far right of the screen was not touchable.
END UPDATE - (original non-answer below)
My answer isn't an answer, but I have run into the exact same issue. On rotate in our app, when building with Xcode 6, I see the exact same rendering issue as the the screenshots on this question. The exact same out of position rotate with black bars at the side and bottom. (Our app on iPhone doesn't support any rotation so we don't see the issue on iPhone. On iPad we support landscape left and landscape right. When rotating from one to the other, when the iPad does it's standard rotation animation, it will rotate out of position (showing the black bars) when going one way and then rotate back into proper position when going back to the other supported orientation. I don't believe it's related to any custom positioning or animation code. It happens with every screen, including the splash screen. It appears to be related to the built in Apple screen rotation. Obviously not every project has this issue in iOS but I have not come across the particulars that are causing this issue. I spent all day yesterday researching the issue and going through our code and I have nothing.
One piece of additional info. If I build with Xcode 6 and run on a device with iOS 7 then there is not issue. This issue ONLY happens when I build with Xcode 6 and run on a device with iOS 8.
Here is a link to my own question posted yesterday about this issue. (I did not come across this question until after I'd posted my question.)
Building project with Xcode 6 (iOS 8 SDK) causes landscape rotation rendering issue on iPad
I found this to be an issue when I had multiple windows in my application. By setting a breakpoint on -[UIWindow setFrame:], I was able to see that upon rotation, the system was giving me giving me an erroneous frame size and position. You can get around this by manually setting your frame to equal [UIScreen mainScreen] bounds] which seems to be correct if you running on iOS7+ and compiling with Xcode6. I found that doing this in -[UIWindow becomeKeyWindow] worked well for me:
- (void)becomeKeyWindow {
[super becomeKeyWindow];
self.frame = [UIScreen mainScreen].bounds;
}
I have used iOS 8 with Autolayout but occur this bug when i try to change background image in UITableViewCell after orientation changed from Landscape to Portrait but after orientation happen still the tableviewcell didn't change the width for landscape mode ,this case happen only in iOS 8 but in iOS7 it was worked correctly
See the blew screenshot for this problem
Portrait
Landscape
I have 2 root view controllers ViewController1 and TabBarController1(there are reasons for making 2 root view-controllers). ViewController1 only supports Portrait mode and TabBarController1 supports all orientations. ViewController1 appears first after launch. I am locking the orientation of ViewController1 using the following method.
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
The app launch and orientation worked fine with iOS7.
When building the app through Xcode 6 in iPad(iOS8) following change is observed:
- When app is launched in landscape mode, ViewController1 with orientation locked into portrait mode appears with half black screen and when TabBarController1 appears which supports all orientations, doesn't resize with proper dimensions on changing orientations.
I have also tried overriding the above method in TabBarController1 to support all orientation but nothing works fine.
This problem is not observed when launching the app on iPad in portrait mode.
There is no problem when launching the app on iPhone as iPhone launches only in Portrait mode.
What is the issue when working with iOS8 ?
I am a newbie, so don't judge..
In ios8, apple changed 2 things :
1-
[[UIscreen mainscreen] bounds].size
This used to be a fixed value for portrait and landscape, now it is not.
When u change from landscape to portrait the width and height switch.
2-What is happening with you. You cannot force a viewcontroller to be in portrait only if you set portrait and landscape in project settings, do not know why, so you maybe have to set portrait only in project settings for example..
This is happening on iPads and iphone 6+ only.
Hope this helped..
I am writing my first iPad application. One of the very first problems i ran into is the screen size in different orientations.
When i try using these two:
view.frame
or
view.bounds
I get the screen resolutions for the portrait mode. Note that i need both the large and mini iPad screen size. I have also tried using mainScreen but i get the same results as the above codes.
Here you go
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
CGFloat width = CGRectGetWidth(self.view.bounds);
}
