首先要允许项目支持横竖屏
一般的项目都会用到navigationController与tabBarController，需要在这二者中先做一些设置
1.navigationController中重写下面有一个方法
-(BOOL)shouldAutorotate
{
return YES;
}
-(UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return [self.viewControllers.lastObject supportedInterfaceOrientations];
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [self.viewControllers.lastObject preferredInterfaceOrientationForPresentation];
}
2.tabBarController中也重写上述三个方法，得实现时有所不同
- (BOOL)shouldAutorotate
{
return [self.selectedViewController shouldAutorotate];
}
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return [self.selectedViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [self.selectedViewController preferredInterfaceOrientationForPresentation];
}
3.在只支持竖屏的controller中也要重写上述方法，支持横屏的controller中不做操作
-(UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait ;
}
- (BOOL)shouldAutorotate
{
return NO;
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
如果设置了还不成功。那就有可能是 statusbar style 没有设置，要把Requre full screen 勾选上
