iphone - MBProgressHUD 没有停止

Question

这是我的代码

MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeIndeterminate;
hud.labelText = @"Loading..";
dispatch_queue_t dispatchQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
dispatch_async(dispatchQueue, ^(void)
{
    [self information];
    [hud hide:YES];
});

我知道方法信息会在一段时间后完成。但即使完成后，进度条也不会消失。可能是什么原因？

像这样做

MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeIndeterminate;
hud.labelText = @"Loading..";
dispatch_queue_t dispatchQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
dispatch_async(dispatchQueue, ^(void)
{
[self information];
dispatch_sync(dispatch_get_main_queue(), ^{ 
[hud hide:YES];
});
});
