iPhone-无法获得界面方向

Question

I'm trying to set another position for a UIButton when I change the orientation of my IPhone and I had the idea to implement it inside BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation. Is this the right way to implement or is there any error on my code? It's not printing these logs.

Code:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

if ((interfaceOrientation == UIDeviceOrientationLandscapeLeft) ||
    (interfaceOrientation == UIDeviceOrientationLandscapeRight))
{
    NSLog(@"Csantos shouldAutorotateToInterfaceOrientation: left or right");
    [adButton setFrame:CGRectMake(100, 700, 768, 90)];
}
if ((interfaceOrientation == UIDeviceOrientationPortrait) ||
    (interfaceOrientation == UIDeviceOrientationPortraitUpsideDown))
{
    NSLog(@"Csantos shouldAutorotateToInterfaceOrientation: Portrait or UpsideDown portrait");
    [adButton setFrame:CGRectMake(0, 0, 768, 90)];
}
return YES;

}

Regards!

Answer 1

shouldAutorotateToInterfaceOrientation simply specifies what rotations are supported by a UIViewController - nothing more.

You may consider modifying willRotateToInterfaceOrientation which is called just before a rotation is about to begin - to hide background views or other objects, for example.

Then, override didRotateFromInterfaceOrientation which is called after a rotation has just finished - I think this one will be the most important for your setFrame: code.

Answer 2

Your code too should work but try putting following code. Change is from UIDeviceOrientation to UIInterfaceOrientation

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    if ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight))
    {
        NSLog(@"Csantos shouldAutorotateToInterfaceOrientation: left or right");
        [adButton setFrame:CGRectMake(100, 700, 768, 90)];
    }
    if ((interfaceOrientation == UIInterfaceOrientationPortrait) || (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown))
    {
        NSLog(@"Csantos shouldAutorotateToInterfaceOrientation: Portrait or UpsideDown portrait");
        [adButton setFrame:CGRectMake(0, 0, 768, 90)];
    }
    return YES;
}

I don't undestand, the adButton setFrame works correctly or not and this viewcontroller is root or you have another one. Can't it be that root controller shouldAutorotateToInterfaceOrientation return NO for any orientation?
