MBProgressHUD的基本使用

2015/06/26 34383

和gitHub上的Demo其实差不多，就是小整理了下，当备忘，想做复杂的效果可以参考MBProgressHUD在gitHub上的DEMO，写得也很清楚明了。

先下载MBProgressHUD.h和.m文件，拖入工程。地址：MBProgressHUD

以下是代码：（先在.h文件里定义 MBProgressHUD *HUD;）

    //方式1.直接在View上show  
    HUD = [[MBProgressHUD showHUDAddedTo:self.view animated:YES] retain];  
    HUD.delegate = self;  
      
    //常用的设置  
    //小矩形的背景色  
    HUD.color = [UIColor clearColor];//这儿表示无背景  
    //显示的文字  
    HUD.labelText = @"Test";  
    //细节文字  
    HUD.detailsLabelText = @"Test detail";  
    //是否有庶罩  
    HUD.dimBackground = YES;  
    [HUD hide:YES afterDelay:2];  
      
    //只显示文字  
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];  
    hud.mode = MBProgressHUDModeText;  
    hud.labelText = @"Some message...";  
    hud.margin = 10.f;  
    hud.yOffset = 150.f;  
    hud.removeFromSuperViewOnHide = YES;  
    [hud hide:YES afterDelay:3];  
      
    //方式2.initWithView  
    //use block  
    HUD = [[MBProgressHUD alloc] initWithView:self.view];  
    [self.view addSubview:HUD];  
    HUD.labelText = @"Test";  
    [HUD showAnimated:YES whileExecutingBlock:^{  
        NSLog(@"%@",@"do somethings....");  
        [self doTask];  
    } completionBlock:^{  
        [HUD removeFromSuperview];  
        [HUD release];          
    }];  
      
    //圆形进度条  
    HUD = [[MBProgressHUD alloc] initWithView:self.view];  
    [self.view addSubview:HUD];  
    HUD.mode = MBProgressHUDModeAnnularDeterminate;  
    HUD.delegate = self;  
    HUD.labelText = @"Loading";  
    [HUD showWhileExecuting:@selector(myProgressTask) onTarget:self withObject:nil animated:YES];  
      
    //自定义view  
    HUD = [[MBProgressHUD alloc] initWithView:self.view];  
    HUD.customView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"37x-Checkmark.png"]] autorelease];  
    // Set custom view mode  
    HUD.mode = MBProgressHUDModeCustomView;  
    HUD.delegate = self;  
    HUD.labelText = @"Completed";  
    [HUD show:YES];  
    [HUD hide:YES afterDelay:3];

代理方法：

    #pragma mark -  
    #pragma mark HUD的代理方法,关闭HUD时执行  
    -(void)hudWasHidden:(MBProgressHUD *)hud  
    {  
        [hud removeFromSuperview];  
        [hud release];  
        hud = nil;  
    }

二个task

 -(void) doTask{  
    //你要进行的一些逻辑操作  
    sleep(2);  
  }  
  
  -(void) myProgressTask{  
       float progress = 0.0f;  
while (progress < 1.0f) {  
    progress += 0.01f;  
    HUD.progress = progress;  
    usleep(50000);  
}  
  
  }
