如何检查iPhone现在的位置（横向或纵向）？ [英] How to check in which position (landscape or portrait) is the iPhone now?

问题描述

我有一个带标签栏的应用程序，每个标签中都有导航控制器。当用户摇动设备时， UIImageView 在导航控制器中显示为子视图。但 UIImageView 必须包含特殊图像，具体取决于设备的当前方向。

I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation.

如果我只写

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)
   if (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { 
   //Code
   }
   else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
   //Code
   }
}

视图如果用户在摇晃之前旋转设备，则会发疯

The view just goes crazy if user rotated the device before shaking.

有没有办法让iPhone进行当前定位？

推荐答案

使用 [[UIDevice currentDevice] orientation] 方法，如指定这里。
