为什么我的iPad应用程序没有检测到方向变化？

Question

Using the following code gives me nothing... My view rotates. Can't understand it...

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}


- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    NSLog(@"I am starting to rotate");
}

Thanks...

Answer 1

This may be due to the way your VC is nested inside a heirarchy of VC's.

This SO post should help you out:

Answer 2

-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
    if(self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
       self.interfaceOrientation == UIInterfaceOrientationLandscapeRight){
           NSLog(@"I am starting to rotate in Landscape");

    } else {
           NSLog(@"I am starting to rotate in Portrait");

    }
}

and leave this like how it was

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}
