UIActionSheet in iOS 8

UIActionSheet and UIActionSheetDelegate is deprecated in iOS 8. To create and manage action sheets in iOS 8 / later, we need to use UIAlertController with a preferredStyle of UIAlertControllerStyleActionSheet because if we have used the same in our previous code it will simply not appear in iOS 8. Don't panic! It won't make a crash ;)

till iOS 7

-(void)pickImage:(UIButton*)sender{
    UIActionSheet *changeImageAction = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:
                            @"Capture Photo",
                            @"Select from Gallery",
                            nil];
    [changeImageAction showInView:[UIApplication sharedApplication].keyWindow];
}

- (void)actionSheet:(UIActionSheet *)popup clickedButtonAtIndex:(NSInteger)buttonIndex {

            switch (buttonIndex) {
                case 0:
                    NSLog(@"Open camera");
                    if ( [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] ){
                        [self getImage:UIImagePickerControllerSourceTypeCamera];
                    }
                    break;
                case 1:
                    NSLog(@"Open gallery");
                    [self getImage:UIImagePickerControllerSourceTypePhotoLibrary];
                    break;
                default:
                    break;
