如何禁用横向方向？ [英] How can I disable landscape orientation?

问题描述

我正在制作iPhone应用程序，我需要它处于纵向模式，因此如果用户侧向移动设备，它不会自动旋转。我该怎么做？

I am making an iPhone app and I need it to be in portrait mode, so if the user moves the device sideways, it does not automatically rotate. How can I do this?

推荐答案

要为特定的视图控制器禁用方向，你现在应该覆盖 supportedInterfaceOrientations 和 preferredInterfaceOrientationForPresentation 。

To disable orientations for a particular View Controller, you should now override supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation.

- (NSUInteger) supportedInterfaceOrientations {
    // Return a bitmask of supported orientations. If you need more,
    // use bitwise or (see the commented return).
    return UIInterfaceOrientationMaskPortrait;
    // return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}

- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation {
    // Return the orientation you'd prefer - this is what it launches to. The
    // user can still rotate. You don't have to implement this method, in which
    // case it launches in the current orientation
    return UIInterfaceOrientationPortrait;
}

如果你的目标是比iOS 6更早的东西，你想要 shouldAutorotateToInterfaceOrientation： 方法。通过更改何时返回yes，您将确定它是否将旋转到所述方向。这只允许正常的纵向方向。

If you're targeting something older than iOS 6, you want the shouldAutorotateToInterfaceOrientation: method. By changing when it returns yes, you'll determine if it will rotate to said orientation. This will only allow the normal portrait orientation.

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait); 

    // Use this to allow upside down as well
    //return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}

请注意 shouldAutorotateToInterfaceOrientation：已在iOS 6.0中弃用。

Note that shouldAutorotateToInterfaceOrientation: has been deprecated in iOS 6.0.
