界面上iOS8与iOS7相比变化不大,只是在功能方面进行了完好。
iOS8中更新和公开了非常多接口,当中有一项本地消息通知UILocalNotification,大家肯定都不陌生。
可是在iOS8中对其进行了优化和改进。
如今它能够依据地理位置发起消息通知,即我们在App中设置好一个坐标(经纬度)和半径(范围),当装有本App的设备进入本区域后,App就会发出一个消息通知。
CLLocationManager *locMan = [[CLLocationManager alloc] init]; locMan.delegate = self; // request authorization to track the user’s location [locMan requestWhenInUseAuthorization];同一时候还要进行配置plist文件
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status { // check status to see if we’re authorized BOOL canUseLocationNotifications = (status == kCLAuthorizationStatusAuthorizedWhenInUse); if (canUseLocationNotifications) { [self startShowingLocationNotifications]; } }回调方法里注冊通知
- (void)startShowingNotifications { UILocalNotification *locNotification = [[UILocalNotification alloc] init]; locNotification.alertBody = @“You have arrived!”; locNotification.regionTriggersOnce = YES; locNotification.region = [[CLCircularRegion alloc] initWithCenter:LOC_COORDINATE radius:LOC_RADIUS identifier:LOC_IDENTIFIER]; [[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; } //- (instancetype)initWithCenter:(CLLocationCoordinate2D)center //区域的中心 经纬度 // radius:(CLLocationDistance)radius //区域半径 范围 // identifier:(NSString *)identifier; //通知的唯一标示 描写叙述
-(void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region { NSLog(@"%s",__func__); } - (void)application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification { CLRegion *region = notification.region; if (region) { [self tellFriendsUserArrivedAtRegion:region]; } }
iOS8新特性之基于地理位置的消息通知UILocalNotification
