iOS 6上的界面旋轉工作，但iOS 5上的界面旋轉工作

Question

我的應用程序旋轉在iOS 3上的iPad 3和iPad 2上正常工作，但在iOS1上未在iPad1上正常工作。

我正在使用標籤欄控制器和5視圖控制器。在每個視圖控制器我有這樣的代碼：

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration{ 
if(self.interfaceOrientation == UIDeviceOrientationPortrait||self.interfaceOrientation == UIDeviceOrientationPortraitUpsideDown){ 
    self.view=self.VerticaleAppunti; 
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"FONDO_VERT.jpg"]]; 
} 
if(self.interfaceOrientation == UIDeviceOrientationLandscapeLeft||self.interfaceOrientation == UIDeviceOrientationLandscapeRight){ 
    self.view=self.OrizzontaleAppunti; 
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"FONDO.jpg"]]; 
} 

}

你可以嘗試實現在iOS 5中這種方法進行定向變化：

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 
    //support for all orientation change 
    return YES; 
} 

orientation support in ios5
