iphone – iOS 6.0中的界面方向

如何在iOS 6.0中使用以下方法支持界面方向：

shouldAutorotate

supportedInterfaceOrientations

preferredInterfaceOrientationForPresentation

因为“shouldAutorotatetoInterfaceOrientation”在iOS 6.0中已弃用。

请提供代码段以支持您的答案。

谢谢。

解决方法

iOS 5中已弃用的方法：

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

在iOS 6中替换，以及相当于上述弃用的iOS 5方法：

- (BOOL) shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight;
}

希望这可以帮助。

-(BOOL)shouldAutorotate

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAll;

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationMaskPortrait;
}

[#edit 2：仅支持iOS 5和iOS 6的仅风景应用程序的示例代码]

- (BOOL)shouldAutorotatetoInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight) || (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

- (BOOL)shouldAutorotate {

    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {

    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {

    return UIInterfaceOrientationLandscapeLeft;
}
