iOS - UIViewcontroller检测旋转？

Question

I am using willRotateToInterfaceOrientation to detect rotation and move items according to the orientation.

The problem is that when the page first loads this method doesn't get called so it doesn't try to move the objects to the correct location?

What is the solution?

Answer 1

You need to setup the interface according to the orientation

if ([UIDevice currentDevice].orientation == UIDeviceOrientationPortrait)  {
     // do something
} else if ([UIDevice currentDevice].orientation == UIDeviceOrientationLandscapeRight) {
     // do something else
}

And repeat that for al the different device orientations

Answer 2

我手动检测UIInterfaceOrientation从我UIApplication ，我叫手动willAnimateRotationToInterfaceOrientation上viewDidAppear
