写一个递归找到 UIAlertController 的 message

UIView *messageParentView = [self getParentViewOfTitleAndMessageFromView:AlertController.view];
    if (messageParentView && messageParentView.subviews.count > 1) {
        UILabel *messageLb = messageParentView.subviews[1];
        messageLb.textAlignment  = NSTextAlignmentLeft;
    }

- (UIView *)getParentViewOfTitleAndMessageFromView:(UIView *)view {
    for (UIView *subView in view.subviews) {
        if ([subView isKindOfClass:[UILabel class]]) {
            return view;
        }else{
            UIView *resultV = [self getParentViewOfTitleAndMessageFromView:subView];
            if (resultV) return resultV;
        }
    }
    return nil;
}

是不是很简单粗暴，欢迎点赞
