UIDeviceOrientationDidChangeNotification为UIOrientationLandscapeRight返回UIOrientationLandscapeLeft [英] UIDeviceOrientationDidChangeNotification is returning UIOrientationLandscapeLeft for UIOrientationLandscapeRight

问题描述

我正在为UIDeviceOrientationDidChangeNotification注册我的viewcontroller，它返回错误的设备方向。
我在viewcontroller的init函数中注册它

I am registering my viewcontroller for UIDeviceOrientationDidChangeNotification and it's return wrong orientation of device. I am registering it in init function of viewcontroller

[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(handleOrientationChangeNotification:) name: UIDeviceOrientationDidChangeNotification object: nil];

这是我的设备通知接收方法。

This is my device Notification Receiver method.

-(void)handleOrientationChangeNotification:(NSNotification *)notification
{ 
    if(IS_IPHONE)
    {
        UIDeviceOrientation currentDeviceOrientation =  [[UIDevice currentDevice] orientation];
    .
    .
    .
}

每当设备方向改变时，我总是出错方向。

Whenever Device Orientation changed,I am always getting wrong orientation.

推荐答案

我在苹果网站上找到了解决方案 link

I find the solution on apple site on this link

UIDeviceOrientationLandscapeRight 已分配给 UIInterfaceOrientationLandscapeLeft 并且 UIDeviceOrientationLandscapeLeft 已分配给 UIInterfaceOrientationLandscapeRight 。原因是旋转设备需要以相反的方向旋转内容。

UIDeviceOrientationLandscapeRight is assigned to UIInterfaceOrientationLandscapeLeft and UIDeviceOrientationLandscapeLeft is assigned to UIInterfaceOrientationLandscapeRight. the reason for this is that rotating the device requires rotating the content in the opposite direction.
