After BLOCK Completed only Return

Question

May I know is what are the solution to use in order to make the following code working in order.

- (CGFloat)getRowImageHeight
{
    CGFloat defaultHeight   =         


        

Answer 1

the good approach would be something like this:

- (void)getRowImageHeightWithCompletionBlock:(void(^)(CGFloat height))completion {
    CGFloat defaultHeight = 300.f;
    [self configureImageTVCell:self.itemImageTVCell block:^(UIImage *image, BOOL succeeded) {
        if(succeeded && completion) {
            completion(image.size.height);
        }
    }];
}
