我只想在我的应用程序中将我的一个 View 旋转到向左横向或向右横向。我的所有其他 View 都处于纵向模式,并且我已将我的应用程序设置为仅支持纵向模式。随着 iOS 6 中方向的改变,我不知道该怎么做。我已经尝试了下面发布的内容。谁能告诉我我做错了什么?谢谢!
-(BOOL)shouldAutorotate {
return YES;
}
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
}
我也试过:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(didRotate:)
name:UIDeviceOrientationDidChangeNotification
object:nil];
return YES;//UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
}
-(void)didRotate:(NSNotification *)notification {
UIDeviceOrientation orientation = [[notification object] orientation];
if (orientation == UIDeviceOrientationLandscapeLeft) {
[theImage setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
} else if (orientation == UIDeviceOrientationLandscapeRight) {
[theImage setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
} else if (orientation == UIDeviceOrientationPortraitUpsideDown) {
[theImage setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
} else if (orientation == UIDeviceOrientationPortrait) {
[theImage setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
}
}
最佳答案
这对我有用 How to force a UIViewController to Portrait orientation in iOS 6
从 UINavigationController 覆盖旋转方法创建一个新类别:
-(BOOL)shouldAutorotate
{
return [self.topViewController shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [self.topViewController preferredInterfaceOrientationForPresentation];
}
