只允許LeftLandscape和RightLandscape方向

Question

如何讓我的應用只允許橫向方向，但都是（左和右）？ 所以如果我旋轉180°的應用程序將被旋轉，但如果我在縱向旋轉應用程序不旋轉？

感謝

嘗試增加這UIViewController中：

// Override to allow orientations other than the default portrait orientation. 
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    // Return YES for supported orientations 
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || 
      interfaceOrientation == UIInterfaceOrientationLandscapeRight); 
}
