第一个:
p>
// 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); }];
p> p> p>第二个: p>非arc: p>
if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) { [[UIDevice currentDevice] performSelector:@selector(setOrientation:) withObject:(id)UIInterfaceOrientationLandscapeRight]; }
p> p>arc下: p>
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]; }
