iOS兩個強制旋轉螢幕的方法

第一個： 

// 狀態列動畫期間  CGFloat duration = [UIApplication sharedApplication].statusBarOrientationAnimationDuration;  [UIView animateWithDuration:duration animations:^{      // 修改狀態列的方向及view的方向進而強制旋轉螢幕      [[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);  }];  

 

  第二個：非arc： 

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

 

 arc下：

 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];          }
