1. // 注册远程通知服务(第一次注册服务的时候会弹出提醒框，让用户授权)

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    // 注册远程通知服务(第一次注册服务的时候会弹出提醒框，让用户授权)    [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert];    　　// 添加一个label，检查启动方式    UILabel *label = [[UILabel alloc] init];    label.backgroundColor = [UIColor lightGrayColor];    label.frame = CGRectMake(0, 100, 320, 300);    label.font = [UIFont systemFontOfSize:15];    label.numberOfLines = 0;    [self.window.rootViewController.view addSubview:label];        NSDictionary *userInfo = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];    if (userInfo) {        label.text = [userInfo description];    } else {        label.text = @"直接点击app图标启动的程序";    }    return YES;}

2.获取设备的deviceToken

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{    NSLog(@"注册远程通知成功----%@", deviceToken);    /**     1.将deviceToken发送给公司的服务器    c330833f 248c4fed e87068b6 c4b90ee8 a2b57119 aac2b93d 3f2eb27f e7d44c8c    c330833f 248c4fed e87068b6 c4b90ee8 a2b57119 aac2b93d 3f2eb27f e7d44c8c}

3.接收到远程推送通知时就会调用

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
    　　// 在这里读取远程通知的一些内容    NSLog(@"接收到远程通知--%@", userInfo[@"userInfo"]);}
