Question

可能重复：
iPhone orientation

如何在iPhone中以编程方式在任何时间点检查设备的方向？

谢谢。

Answer 1

以下是宏UIDeviceOrientationIsLandscape和UIDeviceOrientationIsPortrait

所以请单独检查，你可以这样做......

   if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
    {
         // code for landscape orientation      
    }

OR

    if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation))
    {
         // code for Portrait orientation       
    }

Answer 2

试试吧。

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

if ( ([[UIDevice currentDevice] orientation] ==  UIDeviceOrientationPortrait)  )
{
   // do something for Portrait mode
}
else if(([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight) || ([[UIDevice currentDevice] orientation] == UIInterfaceOrientationLandscapeLeft))
{
   // do something for Landscape mode
}

Answer 3

另请尝试：

UIInterfaceOrientationIsPortrait(orientation)

和

UIInterfaceOrientationIsLandscape(orientation)

Answer 4

-[UIViewController interfaceOrientation]

但是，可以独立于当前界面方向检索deviceOrientation：

[[UIDevice currentDevice] orientation]

阅读文档以获取更多信息，但您需要做更多的事情才能使其发挥作用。

Answer 5

您也可以在功能

中查看

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations

    if(interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
    {
       //do for portrait
    }       
    else 
    { 
       //do for Landscape 
    }
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight || 
            interfaceOrientation == UIInterfaceOrientationPortrait || 
            interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
            interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}

Answer 6

您应该将[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];放在AppDelegate didFinishLaunchingWithOptions

中

然后，在您的应用程序中的任何位置，您都可以通过以下方式获取当前方向：

UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

测试方向：

UIInterfaceOrientationIsPortrait(orientation) UIInterfaceOrientationIsLandscape(orientation)
