UIView has portrait dimensions while in landscape?

Question

I have a storyboard with 1 UIViewController, holding 1 UIView that contains a number of nested UIViews. I subclassed the View Controller to implement this method:

- (BOOL)shouldAutorotateToInterfaceOrientation: UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

I also added

<key>UISupportedInterfaceOrientations</key>
    <array>
     <string>UIInterfaceOrientationLandscapeLeft</string>
     <string>UIInterfaceOrientationLandscapeRight</string>
    </array>
<key>UIInterfaceOrientation</key>
<string>UIInterfaceOrientationLandscapeLeft</string>

to the Info.plist.

In the viewDidLoad of the main UIView I'm doing this:

PASectionView* sectionView = [[PASectionView alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, 180)];
[self addSubview:sectionView];

The problem is the control is only 756px wide instead of the expected 1024. See the screenshot below for details. I've been searching all over the web but I can't find a solution to this frustrating problem anywhere. I'm using Xcode 4.5 with iOS5.1 set as base SDK.

EDIT It's working by replacing frame with bounds. However I don't understand what's happening so it isn't working with the frame size.

Answer 1

The frame rectangle, which describes the view’s location and size in its superview’s coordinate system.

@property(nonatomic) CGRect frame

and

The bounds rectangle, which describes the view’s location and size in its own coordinate system.

@property(nonatomic) CGRect bounds

Use bounds, not frame.

Answer 2

Set the autoresizingMask to whatever views you want to autoresize on rotate. Like this:

[myView setAutoresizingMask:UIViewAutoresizingMaskFlexibleWidth | UIViewAutoresizingMaskFlexibleRightMargin];
