利用 MBProgress 提供的接口方法进行了二次封装拓展.为了更好的使用,特此记录一下,方便今后开发使用带来便捷.
如有更好更优的 demo 欢迎大家分享,共同进步!

}
@end
若不想单起一个类也可以在当前调用方法之处手动添加 runloop 来实现,具体 code 实现如下:
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.001 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
// insert your task code here
[MBProgressHUD showError:@"请输入您的账号" toView:self.view];
});
不断更新中.
