iOS两个强制旋转屏幕的方法

// 状态栏动画持续时间
CGFloat duration = [UIApplication sharedApplication].statusBarOrientationAnimationDuration;
[UIView animateWithDuration:duration animations:^{
// 修改状态栏的方向及view的方向进而强制旋转屏幕
[[UIApplication sharedApplication] setStatusBarOrientation:_bottomView.landscapeModel ? UIInterfaceOrientationLandscapeRight : UIInterfaceOrientationPortrait];
self.navigationController.view.transform = _bottomView.landscapeModel ? CGAffineTransformMakeRotation(M_PI_2) : CGAffineTransformIdentity;
self.navigationController.view.bounds = CGRectMake(self.navigationController.view.bounds.origin.x, self.navigationController.view.bounds.origin.y, self.view.frame.size.height, self.view.frame.size.width);
}];

if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) {
[[UIDevice currentDevice] performSelector:@selector(setOrientation:)
withObject:(id)UIInterfaceOrientationLandscapeRight];
}

if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) {
SEL selector = NSSelectorFromString(@"setOrientation:");
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]];
[invocation setSelector:selector];
[invocation setTarget:[UIDevice currentDevice]];
int val = UIInterfaceOrientationLandscapeRight;
[invocation setArgument:&val atIndex:2];
[invocation invoke];
