Try this:

UIImagePickerController *picker=[[UIImagePickerController alloc]init];
picker.delegate=self;
picker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;

if([[[UIDevice currentDevice] systemVersion] floatValue]>=8.0)
{
    [[NSOperationQueue mainQueue] addOperationWithBlock:^{
        [self presentViewController:picker animated:NO completion:nil];
    }];
}else{
    [self presentViewController:picker animated:YES completion:nil];
}
