我想仅将我的应用程序中的一个视图旋转为左横屏或右横屏。 我的所有其他视图都在竖屏模式下,并且我已将我的应用程序设置为仅支持竖屏模式。由于iOS 6中更改了方向,我不确定如何做到这一点。我尝试了下面发布的方法。有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;
}
我也尝试过:
-(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)];
}
}
