{
[SupportedInterfaceOrientations sharedInstance].orientationMask = UIInterfaceOrientationMaskPortrait;
NSNumber *orientationValue = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
[[UIDevice currentDevice] setValue:orientationValue forKey:@"orientation"];
}
#pragma mark - 横屏
- (void)rotationLandscape
{
[SupportedInterfaceOrientations sharedInstance].orientationMask = UIInterfaceOrientationMaskLandscape;
NSNumber *orientationValue = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeRight];
[[UIDevice currentDevice] setValue:orientationValue forKey:@"orientation"];
}
