iOS螢幕旋轉觸發自定義function (xcode 5)

資料來源與參考：官方：Supporting Multiple Interface Orientations

iOS6之前使用的旋轉函式已經無法使用了，而是使用-(NSUInteger)supportedInterfaceOrientations與-(BOOL)shouldAutorotate來配合旋轉。
但是如果在旋轉後要呼叫自定程序去處理自定界面呢？



首先，這是我的自定義程式：

-(void)turnInterface:(NSInteger)orit{
  NSLog(@"Turn! %d",orit);
}

原本就程式碼寫的旋轉呼叫：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    [self turnInterface:(NSInteger)interfaceOrientation];
    
    return YES;
}

現在則是需要使用didRotateFromInterfaceOrientation:來呼叫程序：

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{
    NSInteger interfaceOrientation = 0;
    if (fromInterfaceOrientation == UIInterfaceOrientationPortrait || fromInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown){
        interfaceOrientation = UIInterfaceOrientationLandscapeLeft;
    }else{
        interfaceOrientation = UIInterfaceOrientationPortrait;
    }
    [self turnInterface:interfaceOrientation];
}
