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

这是宏UIDeviceOrientationIsLandscape和UIDeviceOrientationIsPortrait

所以相反单独检查你可以这样做......

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

要么

    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

还尝试:

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]
