UIImagePickerController not presenting in iOS 8

Question

Is anyone else having an issue with UIImagePickerController in iOS 8? The method below works perfectly well in iOS 7 on an iPad, but I get the following error

Answer 1

Here is a solution that worked for me

if([[[UIDevice currentDevice] systemVersion] floatValue]>=8.0)
{
    [[NSOperationQueue mainQueue] addOperationWithBlock:^{

        [self presentViewController:cameraUI animated:NO completion:nil];
    }];

}
else{

    [controller presentViewController:cameraUI animated:NO completion:nil];
}

Remember to alloc cameraUI

UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;

Build and Go!
