Pls help. I am using UIImagePickerController to pick image from gallery. I worked fine on all iPhone . But its crashing in iPad iOS 8.0.2. Image picker controller is displayed. (All photos and Recently Added) options are shown. But when I click on any one of the above, app crashes.. This happens only in iPad iOS 8.0.2.

Answer 1

On iPad , the correct way to present an image picker is to use a popover . Check official document . Also check example

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
    //Present in Popover
} 
else 
{
    self presentViewController:imagePickerController animated:YES completion:nil];
}
