相册在iPad2中崩溃

Question

I am presenting photo album and camera from a UIButton from a UIPopOverController. Both works fine when I present it in iPad1 running on iOS 5.1 .

When I do the same thing in iPad2 running on iOS 6.0 , the camera works fine but the photo album crashes as in the below image. Also note than the app is a landscape app.

The code Im using is

 //imgPicker.contentSizeForViewInPopover = CGSizeMake(320, 500);
self.popOver = [[UIPopoverController alloc] initWithContentViewController:picker];
popOver.delegate = self;
[self.popOver presentPopoverFromRect:importFromPhotosBtn.frame
                              inView:importFromPhotosBtn
            permittedArrowDirections:UIPopoverArrowDirectionAny
                            animated:YES];

Please someone point me out what went wrong. Im struck up with this for more than half a day. Any timely help is much more appreciated.

Answer 1

The UIImagePicker is supported on the portrait mode. Your application supports only landscape mode, that causes the issue.

Solution:

1. Subclass UIImagePicker class

2. Implement shouldAutorotate in the subclass

     - (BOOL)shouldAutorotate { return NO; } 

3. Use this subclassed UIImagePicker class for creating picker instead of UIImagePicker

Answer 2

Thanks for @Midhum MP's clue, the problem actually was the frame from which I presented the popOver.

The popOver size is 320 x 500 but I was presenting it from the rect containing (221, 360) as the origin, So the size messed up (500 + 360 which is greater than the iPad ht in landscape(768)).

But not sure why it runs in iPad1(iOS 5.1) and not in iPad2 (iOS 6)!

So, I just changed the presenting rect (such that it won't've such mess-ups) which works fine now. It fixed the issue.
