第二次获取ios push deviceToken

Question

我需要获取 deviceToken。 当我向我的应用添加推送通知时，我通过didRegisterForRemoteNotificationsWithDeviceToken 收到了 deviceToken

但现在我需要再次获取它，但我没有保存。 didRegisterForRemoteNotificationsWithDeviceToken 只调用一次，其他时候应用只运行 registerUserNotificationSettings

我想将所有新用户的令牌保存到[NSUserDefaults standardUserDefaults]，但它只适用于新用户。如何处理现有用户？

Answer 1

在“didFinishLaunchingWithOptions”方法中添加如下代码……

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)])
{
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
} 
else
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}

然后在应用启动过程中，每次调用“didFinishLaunchingWithOptions”都会调用“didRegisterForRemoteNotificationsWithDeviceToken”方法。
