CATransform3DMakeRotation似乎只用来工作

我使用下面的非常基本的代码，我想学习如何做转换适合初学者基本横向旋转CATransform3DMakeRotation似乎只用来工作

我想要做的长的第二次的方式来学习不仅仅是在“shouldautorotate”扔东西更多，这是我工作过的现在

- (void)viewDidLoad 
{ 
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil]; 
} 


- (void)didRotate:(NSNotification *)notification 
{ 
    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; 
    if (orientation == UIDeviceOrientationLandscapeRight) 
    { 
     [UIView animateWithDuration:0.2f animations:^{ 
      self.view.layer.transform = CATransform3DMakeRotation(-M_PI/2, 0, 0.0, 1.0); 
      [self.scrollViewImages setContentSize:CGSizeMake(self.view.frame.size.width*self.images.count, 320.0)]; 
      [self.scrollViewImages setContentOffset:CGPointMake(0, 0) animated:YES]; 
     } completion:^(BOOL finished) { 

     }]; 
    } else if(orientation == UIDeviceOrientationPortrait) { 
     [UIView animateWithDuration:0.2f animations:^{ 
      self.view.frame = CGRectMake(0, 0, 320.0, 480.0); 
      self.view.center = CGPointMake(160.0, 240.0); 
      self.view.transform = CGAffineTransformIdentity;    
     } completion:^(BOOL finished) { 

     }]; 
    } 
}

代码但是我第一次从纵向旋转，我得到这个

portrait landscape

但一旦我把它恢复到肖像和旋转，我再次receieve little more correct

我真的很抱歉，如果这是一个愚蠢的问题还是我失去了一些东西明显。我一直在我的帮助下学习自己:)

感谢您的任何帮助，有一个很好的家伙。

如果您更改纵向上的中心或边框，则应该将其更改回横向... 也应在每次旋转时更改滚动视图的contentSize。

尝试这样的事情......

- (void)didRotate:(NSNotification *)notification 
{ 
    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; 
    if (orientation == UIDeviceOrientationLandscapeRight) 
    { 
     [UIView animateWithDuration:0.2f animations:^{ 
      self.view.frame = CGRectMake(0, 0, 480.0, 320.0); 
      self.view.center = CGPointMake(240.0, 160.0); 

      self.view.layer.transform = CATransform3DMakeRotation(-M_PI/2, 0, 0.0, 1.0); 
      [self.scrollViewImages setContentSize:CGSizeMake(self.view.frame.size.width*self.images.count, 320.0)]; 
      [self.scrollViewImages setContentOffset:CGPointMake(0, 0) animated:YES]; 
     } completion:^(BOOL finished) { 

     }]; 
    } else if(orientation == UIDeviceOrientationPortrait) { 
     [UIView animateWithDuration:0.2f animations:^{ 
      self.view.frame = CGRectMake(0, 0, 320.0, 480.0); 
      self.view.center = CGPointMake(160.0, 240.0); 
      self.view.transform = CGAffineTransformIdentity;    

      [self.scrollViewImages setContentSize:CGSizeMake(self.view.frame.size.width*self.images.count, 320.0)]; 
      [self.scrollViewImages setContentOffset:CGPointMake(0, 0) animated:YES]; 

     } completion:^(BOOL finished) { 

     }]; 
    } 
}
