iOS 控制单个控制器旋转
控制单个ViewController 的旋转
//不旋转，保持竖屏 //iOS 5
- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
//iOS 6
- (BOOL)shouldAutorotate
{
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
//始终保持横屏 //iOS 5
- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return (toInterfaceOrientation == self.preferredInterfaceOrientationForPresentation);
}
//iOS 6
- (BOOL) shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
然而上面的代码在有 导航条的情况下，并不好用；解决方式，为导航条UINavigationController 创建一个 分类，并使用如下分类的导航条
@implementation UINavigationController (Rotation)
-(BOOL)shouldAutorotate {
return [[self.viewControllers lastObject] shouldAutorotate];
} -(NSUInteger)supportedInterfaceOrientations {
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
} - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
@end
