UIView has portrait dimensions while in landscape? - objective-c

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];

Answer 3

The problem is because before loading into Landscape mode your lines of code is calling the method loading
in which method are you calling this [PASectionView alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, 180)];
[self addSubview:sectionView]; if it is view controller class then it should be [PASectionView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 180)];
[self addSubview:sectionView]; if it is subclass of UIView then where did you get the ViewDidLoad method.
Now to solve your problem
in .h class:
write this
PASectionView* sectionView;
in .m class implement this method
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
if (toInterfaceOrientation == UIInterfaceOrientationPortrait)
{
}
else // OrientationLandscape
{
sectionView.frame = CGRect(sectionView.frame.origin.x,sectionView.frame.origin.y,self.view.frame.size.width,180);
}

Answer 4

You have to set the Auto resizing mask for your subview,
Add this line of code before adding the subView to the superview, if your subView is added by code.
yourSubView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
else if your subView added in nib file, select the border magnets and resizing masks in the properties of your subView in the nib file.
