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
