启动应用自动登录时怎么去掉如图的弹框

// 开始自动登录回调

-(void)willAutoLoginWithInfo:(NSDictionary *)loginInfo error:(EMError *)error

{

    UIAlertView *alertView = nil;

    if (error) {

        alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"prompt", @"Prompt") message:NSLocalizedString(@"login.errorAutoLogin", @"Automatic logon failure") delegate:nil cancelButtonTitle:NSLocalizedString(@"ok", @"OK") otherButtonTitles:nil, nil];

        

        //发送自动登陆状态通知

        [[NSNotificationCenter defaultCenter] postNotificationName:KNOTIFICATION_LOGINCHANGE object:@NO];

    }

    else{

        alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"prompt", @"Prompt") message:NSLocalizedString(@"login.beginAutoLogin", @"Start automatic login...") delegate:nil cancelButtonTitle:NSLocalizedString(@"ok", @"OK") otherButtonTitles:nil, nil];

        

        

        // 旧数据转换 (如果您的sdk是由2.1.2版本升级过来的，需要家这句话)

        [[EaseMob sharedInstance].chatManager importDataToNewDatabase];

        //获取数据库中的数据

        [[EaseMob sharedInstance].chatManager loadDataFromDatabase];

    }

    

    [alertView show];

}



// 结束自动登录回调

-(void)didAutoLoginWithInfo:(NSDictionary *)loginInfo error:(EMError *)error

{

    UIAlertView *alertView = nil;

    if (error) {

        alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"prompt", @"Prompt") message:NSLocalizedString(@"login.errorAutoLogin", @"Automatic logon failure") delegate:nil cancelButtonTitle:NSLocalizedString(@"ok", @"OK") otherButtonTitles:nil, nil];

        

        //发送自动登陆状态通知

        [[NSNotificationCenter defaultCenter] postNotificationName:KNOTIFICATION_LOGINCHANGE object:@NO];

    }

    else{

        //获取群组列表

        [[EaseMob sharedInstance].chatManager asyncFetchMyGroupsList];

        

        alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"prompt", @"Prompt") message:NSLocalizedString(@"login.endAutoLogin", @"End automatic login...") delegate:nil cancelButtonTitle:NSLocalizedString(@"ok", @"OK") otherButtonTitles:nil, nil];

    }

    

    [alertView show];

}
