ios - 查找启动应用程序 : banner notification, 警报通知或图标点击的事件？

Question

我可以找出在 iOS 上启动应用程序的事件吗？

我需要区分以下内容:

1. 点击图标
2. 横幅通知
3. 警报通知

或者，我可以查看应用程序本地设置(横幅或警报通知设置)吗？

Answer 1

要确定应用程序是否是通过按下通知启动的，您需要实现 2 个方法。

首先，在应用程序 didFinishLaunchingWithOptions 中，执行以下操作:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
if ([launchOptions valueForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"]) {
 // Handle notification
}

第二:

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
if (application.applicationState == UIApplicationStateActive) {
    // The app was open when a remote notification was received...
} else {
    // The app was in the background and just came to the foreground in response to the user pressing the push notification
}

}

您可以使用以下方式查看已启用的通知类型:

UIRemoteNotificationType notificationTypes = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

但是，您无法区分横幅通知或警报通知。
