我喜欢使用此代码在iPhone 6上支持splitViewController:
- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id <UIViewControllerTransitionCoordinator>)coordinator
{
self.forcedTraitCollection = nil;
if (size.height == 320.0 || size.width == 320.0)
{
self.forcedTraitCollection = nil;
}
else
{
self.forcedTraitCollection = [UITraitCollection traitCollectionWithHorizontalSizeClass:UIUserInterfaceSizeClassRegular];
}
[super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
}
问题是返回的大小是错误的 - 它为所有模拟器返回CGSize(320,568)。 + n它返回宽度作为高度,反之亦然。

我为不同的设备模拟器获取了正确的尺寸,但是在横向模式下,x和y似乎被翻转。我用这个黑客来纠正它:
let mainScreen = UIScreen.mainScreen()
let screenSize = mainScreen.applicationFrame // CGRect screen bounds
var width = size.width
if screenSize.width == size.width {
// size must be wrong or flipped
width = size.height
}
