注册后更新解析deviceToken

Question

目前，我使用了相当多的空deviceToken字段。我发现这是因为在创建安装对象之前添加组有一个问题-它会阻止后续的创建工作。

我现在想做的是再次获取deviceToken并在解析器中更新它，但问题是，didRegisterForRemoteNotificationsWithDeviceToken在第一次之后再也不会运行了……

在初始调用didRegisterForRemoteNotificationsWithDeviceToken之后获取设备令牌的任何方法

Answer 1

这确实适用于iOS 8：

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

didRegisterForRemoteNotificationsWithDeviceToken可以重复调用。只需在didFinishLaunchingWithOptions方法中调用AppDelegate.m中的推送注册码即可。

下面是我的用法：

//Check for iOS 7 vs 8
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
} else {
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}

就是这样--如果你每次都调用它，你会在每次加载时得到一个对didRegisterForRemoteNotificationsWithDeviceToken的委托回调。
