本文介绍了一个基于MBProgressHUD的封装实现，提供了多种MBProgressHUD展示方式，包括文本、进度条、取消按钮等，并支持延迟隐藏及自定义代码块执行。

下面是我基于MBProgressHUD的封装

#import <Foundation/Foundation.h>
#import "MBProgressHUD.h"

@interface MBHUDHelper : NSObject


/**
 * 显示MBProgressHUD指示器
 * api parameters 说明
 * aTitle 标题
 * aMsg 信息
 * aImg 图片, 为nil时,只显示标题
 * d 延时消失时间, 为0时需要主动隐藏
 * blockE 执行的代码快
 * blockF 结束时的代码块
 * 执行时改变hub需要调用Common_MainFun(aFun)
