iphone - 当 App 处于后台模式时，UILocalNotification 可以触发自定义方法吗？

Question

好吧，标题是不言自明的。我想创建一个应用程序，当应用程序处于后台模式时，它可以管理编程的本地通知。通知工作顺利，但我想在触发警报时触发自定义方法。

这可能吗？谢谢。

是的，这是可以做到的。你可以这样做:

- (void)applicationDidEnterBackground:(UIApplication *)application {
    [NSTimer scheduledTimerWithTimeInterval:17.0 target:self selector:@selector(makeNotificationRequest:) userInfo:nil repeats:YES];
}

-(void)makeNotificationRequest:(NSTimer *)timer
{
    CLLocation *location = [[AppHelper appDelegate] mLatestLocation];
    NSMutableDictionary *paramDic = [[NSMutableDictionary alloc] init];

#ifdef _DEBUG
    [paramDic setValue:[NSString stringWithFormat:@"77.586"] forKey:@"Lat"];
    [paramDic setValue:[NSString stringWithFormat:@"12.994"] forKey:@"long"];
#else
    [paramDic setValue:[NSString stringWithFormat:@"%f",location.coordinate.latitude] forKey:@"Lat"];
    [paramDic setValue:[NSString stringWithFormat:@"%f",location.coordinate.longitude] forKey:@"long"];
#endif

    WNetwork *mNetwork = [[WNetwork alloc] init];
    [mNetwork makeRequsetWithURL:URL_Showbeeps type:JBJsonParser paramDictionary:paramDic delegate:self];
    [mNetwork autorelease];
    NSLog(@"URL HIT%@",paramDic);
    [paramDic autorelease];
}

要自定义警报时的操作，您可以使用:

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    UIApplicationState state = [application applicationState];
    if (state == UIApplicationStateActive) {
        ;
    }
}
