调用 presentLocalNotificationNow 时触发 didReceiveLocalNotification

Question

当我创建本地通知回调时 didReceiveLocalNotification 被触发。当我点击本地通知时会触发相同的回调。目前我通过检查

来划分这两种情况

if ([UIApplication sharedApplication].applicationState == UIApplicationStateInactive) {
    //this means notification is clicked
}

但这里的主要问题是，当您在前台滑动通知菜单，然后收到本地通知时，会调用此回调 didReceiveLocalNotification。在这种情况下，我的应用进入了这个 if。因此，当应用程序处于非活动状态时，我无法真正区分单击通知和创建本地通知。关于如何解决此问题的任何想法？

这是安排本地通知的代码：

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.alertBody = @"aaaa";
localNotification.alertTitle = @"title";
localNotification.userInfo = myUserInfo;
[[UIApplication sharedApplication] presentLocalNotificationNow:localNotification];

调用此函数后，我触发了 didReceiveLocalNotification 委托。

Answer 1

我不得不在我的应用程序中解决完全相同的问题。我无法在 API 中找到区分差异的官方方法，但这里有一个解决方法。

创建本地通知时在 userInfo 中传递当前日期：

localNotification.userInfo = ["alertDate": NSDate()]

并且当您处理 didReceiveLocalNotification 时，再次检查当前日期，以确保它不是刚刚触发的：

if application.applicationState == .Inactive {
    if let alertDate = notification.userInfo?["alertDate"] as? NSDate 
        where (NSDate()).timeIntervalSinceDate(alertDate) > 0.1 {
        // this means notification was initiated by user
    }
}

Answer 2

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:1];
localNotification.alertBody = @"image inserted";
localNotification.timeZone = [NSTimeZone defaultTimeZone];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
[self dismissViewControllerAnimated:YES completion:nil];

调用 presentLocalNotificationNow 时触发 didReceiveLocalNotification

didReceiveLocalNotification triggered when presentLocalNotificationNow is called
