选择需要对HUD的一些基本属性进行操作修改

其中HUD.mode是选择HUD样式(具体样式参考代码实现效果)

HUD.labelText = @"正在努力加载中...";    HUD.detailsLabelText = @"loading...";//    HUD.color = [UIColor colorWithRed:0.22 green:0.50 blue:0.75 alpha:0.68];//设置整个HUD背景色        HUD.square = YES;//设置HUD是否方形显示

添加上HUD的监听即可实现简单的HUD 效果

[HUD showWhileExecuting:@selector(myProgressTask) onTarget:self withObject:nil animated:YES];

要想实现MBPreogressHUD协议里面的东西对HUD添加代理delegate即可

具体的完整效果模式需要参考MBPreogressHUD的第三方源代码 如下
