本地通知重复间隔

uilocalnotification notifications ios

我的应用程序是关于显示学生时间表的,我想添加本地通知 repeatInterval .
我打算用开关按钮。

我尝试了这段代码,但现在不起作用:

    -(IBAction)theSwitch:(id)sender{
if (switcher.on) {
    NSCalendar *gregCalendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSGregorianCalendar];
    NSDateComponents *dateComponent = [gregCalendar components:NSYearCalendarUnit  | NSWeekCalendarUnit fromDate:[NSDate date]];

    [dateComponent setWeekday:3]; // For tuesday
    [dateComponent setHour:13];
    [dateComponent setMinute:41];

    NSDate *fireDate = [gregCalendar dateFromComponents:dateComponent];

    UILocalNotification *notification = [[UILocalNotification alloc]init];
    [notification setAlertBody:@"ALARM!"];
    [notification setFireDate:fireDate];
    notification.repeatInterval = NSWeekCalendarUnit;
    [notification setTimeZone:[NSTimeZone defaultTimeZone]];
    [[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
else  {UIApplication *app=[UIApplication sharedApplication];
[app scheduleLocalNotification:nil];
}
    }

因此,我需要更多关于这方面的指导,以及如何实现这一目标的一些建议。

如果您无法获得本地通知,请检查下面的代码。

在AppDelegate.m文件中添加代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Handle launching from a notification
UILocalNotification *localNotification =
[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotification) {
    NSLog(@"Recieved Notification %@", localNotification);
}
return YES;
}

添加处理本地通知的方法

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notification {
// Handle the notificaton when the app is running
NSLog(@"Recieved Notification %@", notification);
}
