推送测试，生产环境无法打印log获取deviceToken,可以通过弹窗获取deviceToken

z- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    NSString *token = [[[[deviceToken description]
                         stringByReplacingOccurrencesOfString:@"<"
                         withString:@""]
                        stringByReplacingOccurrencesOfString:@">"
                        withString:@""]
                       stringByReplacingOccurrencesOfString:@" "
                       withString:@""];
    NSLog(@"deviceToken:\n%@\n", token);

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"当前的token" message:token delegate:nil cancelButtonTitle:nil otherButtonTitles:@"确定", nil];
    [alertView show];

    NSString *tokens = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    NSLog(@"deviceToken=%@", tokens);

//    [self testGetClientId];

}

想要在生产环境测试推送，但是生产环境看不到log信息，怎么办呢？写个弹窗，显示deviceToken,打包成ADhoc,上传蒲公英，下载安装后就能看到生产环境的deviceToken了。注意：生产环境的deviceToken跟开发环境不同。获取生产环境的deviceToken后就能在生产环境测试推送了

这玩意是设置了推送能力之后自动生成的
