ios - 应用程序在后台时显示通知

Question

当应用程序在后台运行时，我需要显示某些本地通知。如果没有 NSNotificationCenter 的帮助，我该怎么做？

Answer 1

安德烈·切尔努卡(Andrey Chernukha)的第一条评论是正确的。下面是实现简单本地通知的代码:

    UILocalNotification *localNotification = [[UILocalNotification alloc] init];
    localNotification.repeatInterval = 0;
    NSDate *now = [NSDate date];
    NSDate *dateToFire = [now dateByAddingTimeInterval:10];

    localNotification.fireDate = dateToFire;
    localNotification.alertBody = @"Test local notification";
    localNotification.soundName = UILocalNotificationDefaultSoundName;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
