iOS MBProgressHUD 常用的四种方式

效果一 只显示文字:

// 只显示文字
- (void)TextButtonAction{
    
    self.HUD = [[MBProgressHUD alloc] initWithView:self.view];
    [self.view addSubview:_HUD];
    _HUD.labelText = @"加载中,请稍等...";
    _HUD.mode = MBProgressHUDModeText;
    
    [_HUD showAnimated:YES whileExecutingBlock:^{
        sleep(2);
        
    }
       completionBlock:^{
           [_HUD removeFromSuperview];
           _HUD = nil;
       }];

}

效果二 圆形进度条

// 圆形进度条
- (void)CircularButtonAction{
    
    //圆形进度条
    self.HUD = [[MBProgressHUD alloc] initWithView:self.view];
    
    [self.view addSubview:_HUD];
    
    _HUD.mode = MBProgressHUDModeDeterminate;
    
    _HUD.delegate = self;
    
    _HUD.labelText = @"等待中";
    
    [_HUD showWhileExecuting:@selector(ProgressBar) onTarget:self withObject:nil animated:YES];
}



//  进度条  计算
- (void)ProgressBar{
    // 进度指示器，从0.0到1.0，默认值为0.0
    float progress = 0.0f;
    
    while (progress < 1.0f) {
        
        progress += 0.01f;
        
        _HUD.progress = progress;
        
//        usleep函数能把进程挂起一段时间， 单位是微秒（千分之一毫秒）
        usleep(50000);
    }
}

</br>
效果三 文字 加 菊花

//   通常情况  文字  加 菊花
- (void)GeneralButtonAction{
    //初始化进度框，置于当前的View当中
    self.HUD = [[MBProgressHUD alloc] initWithView:self.view];
    [self.view addSubview:_HUD];
    
    //如果设置此属性则当前的view置于后台
    _HUD.dimBackground = YES;
    
    //设置对话框文字
    _HUD.labelText = @"加载中";
    //细节文字
    _HUD.detailsLabelText = @"请耐心等待";
    
    //显示对话框
    [_HUD showAnimated:YES whileExecutingBlock:^{
        //对话框显示时需要执行的操作
        sleep(3);
    }// 在HUD被隐藏后的回调
       completionBlock:^{
           //操作执行完后取消对话框
           [_HUD removeFromSuperview];
           _HUD = nil;
    }];
}

效果四 自定义动图

//   自定义 动图
- (void)CustomButtonAction{
    
    //自定义view
    self.HUD = [[MBProgressHUD alloc] initWithView:self.view];
    //取消背景框
    self.HUD.color = [UIColor whiteColor];
    
    [self.view addSubview:_HUD];
    
    UIImageView *images = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 200, 300)];
    
    NSMutableArray *imageArray = [[NSMutableArray alloc]init];
    
    for(int i = 1; i < 8 ; i++){
        NSString *imgName = [NSString stringWithFormat:@"%d.tiff",i];
        
        [imageArray addObject:[UIImage imageNamed:imgName]];
    }
    
    images.animationDuration = 0.7;
    
    images.animationImages = imageArray;
    // 开始播放
    [images startAnimating];
    
    
    //自定义
    _HUD.mode = MBProgressHUDModeCustomView;
    _HUD.delegate = self;
    
    _HUD.customView = images;
    
    [_HUD show:YES];
    //延迟
    [_HUD hide:YES afterDelay:2];
    
}
