- (void) didClickDone{ 
    if (isValide ==0) { 
     (...) 
     [newFormDataRequest setDelegate:self]; 
     [newFormDataRequest startAsynchronous];

     //show the label 
     [self showWithLabel]; 
    } 
} 




# pragma mark - AsiHTTPRequest delegate methods 
- (void)requestFinished:(ASIHTTPRequest *)request 
{ 
    NSLog(@"PostAdRequest = %@", [request responseString]); 
    HUD.customView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"37x-Checkmark.png"]] autorelease]; 
    HUD.mode = MBProgressHUDModeCustomView; 
    HUD.labelText = @"Completed"; 
    sleep(10); 
    [self hudWasHidden]; 
    [self dismissModalViewControllerAnimated:YES]; 
}

我想从AsiHTTPRequest获得积极答案后更改MBPrograssHub。但观点依然如此。你知道为什么吗？MBProgressHUB混合查看

因为sleep(10)是不允许UIThread更新HUD。

- (void)requestFinished:(ASIHTTPRequest *)request { 
    NSLog(@"PostAdRequest = %@", [request responseString]); 
    HUD.customView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"37x-Checkmark.png"]] autorelease]; 
    HUD.mode = MBProgressHUDModeCustomView; 
    HUD.labelText = @"Completed"; 

    [self performSelector:@selector(removeHUD) withObject:nil afterDelay:10.0f]; 
} 

- (void) removeHUD { 
    [self hudWasHidden]; 
    [self dismissModalViewControllerAnimated:YES]; 
}

哎呀！真棒！非常感谢你 –

我甚至不知道你为什么在这里使用sleep（）：你永远不应该暂停主线程，并且在大多数操作的辅助线程上使用它并不是所有的原因 - Objective如果你确实需要它，-C就拥有'sleep（）'的包装器。 – lxt

他可能希望该对话框可见，以便告诉用户它已完成请求。 – rckoenes
