Is there a special method to get iPhones orientation? I don't need it in degrees or radians, I want it to return an UIInterfaceOrientation object. I just need it for an if-else construction like
if(currentOrientation==UIInterfaceOrientationPortrait ||currentOrientation==UIInterfaceOrientationPortraitUpsideDown) {
//Code
}
if (currentOrientation==UIInterfaceOrientationLandscapeRight ||currentOrientation==UIInterfaceOrientationLandscapeLeft ) {
//Code
}
提前谢谢！
答
这很可能是您想要的:
UIInterfaceOrientation interfaceOrientation = [[UIApplication sharedApplication] statusBarOrientation];
然后您可以使用系统宏，例如:
You can then use system macros like:
if (UIInterfaceOrientationIsPortrait(interfaceOrientation))
{
}
如果要使用设备方向:
UIDeviceOrientation deviceOrientation = [[UIDevice currentDevice] orientation];
这包括UIDeviceOrientationFaceUp和UIDeviceOrientationFaceDown
