iOS UILocationNotification 本地通知

1.注册本地通知

/** 注册本地通知 */- (void)registerUserNotification {    // 判读系统版本是否是“iOS 8.0”以上    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0 ||        [UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]) {        // 定义用户通知类型(Remote.远程 - Badge.标记 Alert.提示 Sound.声音)        UIUserNotificationType types = UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;        // 定义用户通知设置        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:nil];        // 注册用户通知 - 根据用户通知设置        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];    }}

2.创建一个本地通知

NSInteger time = _textField.text.integerValue;    UILocalNotification *localNotification = [[UILocalNotification alloc] init];    if (localNotification) {        // 使用本地时区        localNotification.timeZone = [NSTimeZone defaultTimeZone];        //设置触发通知时间        localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:time];        //通知参数        localNotification.userInfo = @{@"type":[NSString stringWithFormat:@"test:%ld",(long)time],@"time":@(time)};;        //通知声音        localNotification.soundName = UILocalNotificationDefaultSoundName;        //通知内容        localNotification.alertBody = @"test";        localNotification.repeatInterval = 0;//不重复        //注册通知        [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];    }

3.收到本地通知

1. 如果应用在前台，会在- (void)application:(UIApplication )application didReceiveLocalNotification:(UILocalNotification )notification 中收到通知。
2. 如果应用是关闭或者在后台，会在状态栏收到通知。
   通过点击状态栏通知打开应用，在- (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions 中，通过
   UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

   可以获取本地通知信息。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    // Override point for customization after application launch.    [self registerUserNotification];    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];    //本地通知处理    UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];    if ([localNotification isKindOfClass:[UILocalNotification class]]) {    //---1        NSLog(@"通知内容1%@",localNotification);//        [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];    }    [self p_showBtnAction];    return YES;}- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {    if ([UIApplication sharedApplication].applicationState == UIApplicationStateInactive) {    //-----2        NSLog(@"收到本地通知");    }else if ([UIApplication sharedApplication].applicationState == UIApplicationStateActive){    //----3        AudioServicesPlaySystemSound(1007);    }    NSString * msg = [[NSString alloc] initWithFormat:@"%@-%lu-%@",notification.userInfo,(unsigned long)notification.repeatInterval,notification.repeatCalendar ];    UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:@"通知" message:msg delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];    [alertView show];    NSLog(@"收到通知:%@",notification);    NSLog(@"=============");    [self p_showBtnAction];}

在1 的地方可以处理本地通知，进行页面跳转等操作；

如果不在1的地方处理，可以调用[[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; 这样didReceiveLocalNotification会被调用。

在2的地方表示点击了状态栏的通知消息，可在此进行操作。

在3的地方添加声音提示，应用在前台时收到本地通知会被调用。

需要注意的地方

1. for (UILocalNotification* noti in [UIApplication sharedApplication].scheduledLocalNotifications) {
NSLog(@"通知:%@",noti);
}

   可遍历所有本地通知。

2. 如果 localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:0];立即通知的，通知不会加入到 [UIApplication sharedApplication].scheduledLocalNotifications数组中。

3. 走到didReceiveLocalNotification的通知，会自动从[UIApplication sharedApplication].scheduledLocalNotifications数组中删除。
