創建通知

 

 

UILocalNotification *notification = [[UILocalNotification alloc] init];
    if (notification)
    {
        NSDate *now = [NSDate new];
        notification.fireDate = [now dateByAddingTimeInterval:10]; //10秒後通知
        notification.repeatInterval=0; //重復次數，kCFCalendarUnitWeekday一周一次
        notification.timeZone = [NSTimeZone defaultTimeZone]; //設置時區
        notification.applicationIconBadgeNumber = 1; //應用的角標
        notification.soundName = UILocalNotificationDefaultSoundName; //聲音，可以換成alarm.soundName = @sound.wav
        //去掉下面2行就不會彈出提示框
        notification.alertBody = @通知內容; //提示信息 彈出提示框
        notification.alertAction = @打開; //提示框按鈕
        //notification.hasAction = NO; //是否顯示額外的按鈕，為no時alertAction消失
        NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@value forKey:@key];
        //設置userinfo 方便在之後需要撤銷的時候使用 也可以傳遞其他值，當通知觸發時可以獲取
        notification.userInfo = infoDict;
        
        [[UIApplication sharedApplication] scheduleLocalNotification:notification];
    }

 

推送的內容

//推送的內容
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification
{


    //這裡，你就可以通過notification的useinfo，干一些你想做的事情了
    if ([[notification.userInfo objectForKey:@key] isEqualToString:@value])
    {
           UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@系統提示 message:@你的系統存在嚴重威脅 delegate:nil cancelButtonTitle:@關閉 otherButtonTitles:nil,nil];
           [alert show];
        
    }
    application.applicationIconBadgeNumber = 0; //移除角標
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    //不通過推送 通過應用圖標打開應用 移除角標
    application.applicationIconBadgeNumber = 0;
}

取消通知

//獲取當前所有的本地通知
    NSArray *notificaitons = [[UIApplication sharedApplication] scheduledLocalNotifications];
    if (!notificaitons || notificaitons.count <= 0)
    {
        return;
    }
    //取消一個特定的通知
    for (UILocalNotification *notify in notificaitons)
    {
        if ([[notify.userInfo objectForKey:@key] isEqualToString:@value])
        {
            [[UIApplication sharedApplication] cancelLocalNotification:notify];
            break;
        }
    }
    
//    //取消所有的本地通知
//    [[UIApplication sharedApplication] cancelAllLocalNotifications];
