iOS - UIView in landscape mode is not rotating - iphone

Question

I'm writing an app support for both iPhone & iPad. In iPhone required Portrait mode, iPad required to use Landscape.
In AppDelegate.m
if ([CKAppDelegate isPad]) {
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];
CGSize size = [self getScreenSize];
navigationController = [[UINavigationController alloc] initWithRootViewController:[[PadMainViewController alloc] initWithFrame:CGRectMake(0, 0, size.width, size.height)]];
} else {
CGSize size = [self getScreenSize];
navigationController = [[UINavigationController alloc] initWithRootViewController:[[MainViewController alloc] initWithFrame:CGRectMake(0, 0, size.width, size.height)]];
}
self.window.rootViewController = navigationController;
...
- (CGSize)getScreenSize
{
CGSize size;
if (UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) && [[UIScreen mainScreen] bounds].size.height > [[UIScreen mainScreen] bounds].size.width) {
// in Landscape mode, width always higher than height
size.width = [[UIScreen mainScreen] bounds].size.height;
size.height = [[UIScreen mainScreen] bounds].size.width;
} else if (UIInterfaceOrientationIsPortrait([UIApplication sharedApplication].statusBarOrientation) && [[UIScreen mainScreen] bounds].size.height < [[UIScreen mainScreen] bounds].size.width) {
// in Portrait mode, height always higher than width
size.width = [[UIScreen mainScreen] bounds].size.height;
size.height = [[UIScreen mainScreen] bounds].size.width;
} else {
// otherwise it is normal
size.height = [[UIScreen mainScreen] bounds].size.height;
size.width = [[UIScreen mainScreen] bounds].size.width;
}
return size;
}
In PadMainViewController.m
- (id)initWithFrame:(CGRect)frame
{
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, frame.size.width * 0.7, frame.size.height)];
leftView.backgroundColor = [UIColor cyanColor];
UIView *rightView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, frame.size.width * 0.3, frame.size.height)];
rightView.backgroundColor = [UIColor yellowColor];
self.chopInkButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[self.chopInkButton setTitle:#"Tap to ChopInk" forState:UIControlStateNormal];
self.chopInkButton.frame = CGRectMake(50, 200, 250, 44);
[self.chopInkButton addTarget:self action:#selector(chopInkButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
[rightView addSubview:self.chopInkButton];
self.logoImageView.frame = CGRectMake(50, 50, 100, 100);
[self.logoImageView.layer setBorderColor:[[UIColor blackColor] CGColor]];
[self.logoImageView.layer setBorderWidth:2.0f];
[rightView addSubview:self.logoImageView];
[self.view addSubview:leftView];
[self.view addSubview:rightView];
return self;
}
...
- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)toInterfaceOrientation
{
return (UIInterfaceOrientationIsLandscape(toInterfaceOrientation));
}
The result that I get is
In project summary, I already disabled the portrait mode for iPad
Any idea why the button is not rotating?

Answer 1

Try to use below methods : for iOS 6
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
- (BOOL)shouldAutorotate
{
return YES;
}

Answer 2

I solve this by changing
PadMainViewController.m
- (id)initWithFrame:(CGRect)frame
{
...
return self;
}
to
- (id)initWithFrame:(CGRect)frame
{
if ((self = [super init])) {
...
}
return self;
}
By the way, the initWithFrame is self defined function.
