I have the following code in the viewWillAppear function:
CAGradientLayer *bgLayer = [BackgroundLayer yellowGradient];
[bgLayer setBounds:self.view.bounds];
[self.view.layer insertSublayer:bgLayer atIndex:0];
It works perfectly in portrait orientation. However, when the device goes into landscape mode, it produces a white (or default color) background down the side. I have seen other examples of WHY this occurs, but nothing on how to fix it.
What I’m seeing happening is the 1024 resolution on landscape (iPad) dropping to 1004, and I think it’s adjusting it to 0,20 on the x, y.
Has anyone else run into this issue and found how to fix it?
It’s because when you turn the screen sideways, your view, which has a certain background color, does not turn sideways. The view remains in portrait. So you have this portrait-oriented colored view that’s going from the new “top” of the iPad to way below off screen, and on the right side, the view isn’t wide enough to reach, so you just see the app’s default (white) background color.
You can:
apply a CGAffineTransformMakeRotation rotation to your self.view 90º, so that it now displays properly in your now-landscape application,
make your view big enough to cover the entire device, in both landscape and portrait,
make a view with the proper landscape dimensions, and add it when the iPad rotates, or
disable those allowed interface orientations in your Xcode main project file.

I'm trying to draw a line from the bottom middle to the center of the screen. The values I was using for my two points seemed really odd so I knew something was off. I changed the aspect mode to aspectFit to see what was happening and lo and behold my view seemed to be in portrait even though my app specifies landscape. Does anyone know what is causing this? In the build settings I have only landscape checked.
How Can I make some of my UIViews to be orientation independent and some of them dependent. I'm looking for effect similar to this in standard iOS 9 Camera App when user change orientation from Portrait to Landscape. In Camera View Controller only left Icons and Right Icons are rotating but the internal view stays on position independently.
I just started testing my app on an iPad 2 thats still running iOS 7, because thats what I had lying around. As soon as I open up the app, the main view under the UINavigationController is offset and too small. Heres a picture of what I'm talking about:
The whole screen should be the light color. I use [UIScreen mainScreen].bounds to make the lighter view. I'm compiling this on the iOS 8.2 SDK. After logging the width and height, it seems like they're inverted. Is that how iOS 7 handles things? I think just checking if its running iOS 7 and swapping them will work, but I want to make sure this is the problem. Thanks.
EDIT:
Swapping them worked, but when I go to another view, that view is also rotated, and those are normal views.
iOS8 bounds are relative to orientation thus a device in landscape will have different bounds from the same one on portrait , in iOS7 this does not happen, the bounds are the same no matter if you are in portrait or landscape

In my iPad app, i am supporting only portrait mode except on one screen. I have tab bar at bottom, on click of any tab,it opens a small view of size 320.0 * 600.0, with table view. On selecting any row in small view, a full screen view opens up. Problem is that when i came on full screen view which supports all orientations, next time,my other view especially the small view comes up with frame size of 768 * 1024.
Any sugeestions or help is appreciated!
I'm guessing the problem is that you read the frame size while still being in landscape mode. If you are running things in the simulator, it probably jumps back to portrait when you dismiss the full screen? This forces the app back to "portait" mode without triggering the normal "willRotate" functionality, and could possibly mess up your code for keeping track of orientations.
Also keep in mind that most apps needs to support all orientations on the iPad to get accepted, unless you're making e.g. a game which is normally specifically designed for either landscape or portrait.
I am recreating the Camera app interface for my iPhone app. When it is rotated on its side, instead of rotating the entire UI, I only rotate the icons, just like the normal camera app does. This has worked just fine, but with iOS 5 the notification center orientation depends on the app's orientation. Since my app technically stays in portrait orientation, you can only access the notification center from the top of the screen, even when held sideways. The default camera app has somehow avoided this problem.
I figured the best way to do this is to silently update the UI to be in a different orientation, but from the user's perspective only the icons update. I've tried to achieve this by returning YES in shouldAutorotateToInterfaceOrientation:, and then setting the transform property to rotate the view in willAnimateRotationToInterfaceOrientation:duration:. This works, except it shows an animation where it moves the newly rotated view to its proper position. How can I achieve this without any visible animation?
The answer is actually very simple. All I had to do was change the statusBarOrientation property on [UIApplication sharedApplication] to whatever UIInterfaceOrientation I wanted.
