MBProgressHUD框架的使用

MBProgressHUD框架是一个刷新的框架，再不占据主线程的情况下，开发一个新线程，具体用法如下：

1.

//刷新

-(void)loading:(NSString *)title{

   if (hud!=nil) {

        [hudremoveFromSuperview];

    }

    hud=[[MBProgressHUDalloc]initWithWindow:[UIApplicationsharedApplication].keyWindow];

    [[UIApplicationsharedApplication].keyWindowaddSubview:hud];

    hud.mode=MBProgressHUDModeIndeterminate;

    hud.delegate=self;

    hud.detailsLabelText=title;

    [hudshow:YES];

}

//停止刷新

-(void)loadhidden:(float)time{

    [selfperformSelector:@selector(hide)withObject:selfafterDelay:time];

}

-(void)hide{

    [hudhide:YES];

}

//清除缓存

- (void)hudWasHidden:(MBProgressHUD *)theHud {

    [hudremoveFromSuperview];

}

2.或者是

- (IBAction)showSimple:(id)sender {

        //单纯刷新

// The hud will dispable all input on the view (use the higest view possible in the view hierarchy)

HUD = [[MBProgressHUDalloc]initWithView:self.navigationController.view];

[self.navigationController.viewaddSubview:HUD];

// Regiser for HUD callbacks so we can remove it from the window at the right time

HUD.delegate =self;

// Show the HUD while the provided method executes in a new thread

[HUDshowWhileExecuting:@selector(myTask)onTarget:selfwithObject:nilanimated:YES];

        

        //带标题

         HUD.labelText =@"Loading";

        //副标题

HUD.detailsLabelText =@"updating data";

HUD.square =YES;

        //调节模式

        HUD.mode =MBProgressHUDModeDeterminate;（闹钟转动）

        //显示，隐藏

[HUDshow:YES];

[HUDhide:YESafterDelay:3];

}
