Question

大家好，在我的应用程序中，我在这里找到了iBeacons，当我从Region退出时调用了didExitRegion方法，但是当我进入region.i修复了后台刷新，远程通知时，没有调用didEnterRegion方法。位置请求始终在info.plist

这是我的代码

- (void)viewDidLoad
{
    [super viewDidLoad];
    locManager=[[CLLocationManager alloc] init];
    locManager.delegate=self;

    [self initRegion];
    if([locManager respondsToSelector:@selector(requestAlwaysAuthorization)])
    {
        [locManager requestAlwaysAuthorization];
    }
//    clBeconRegion.notifyOnEntry=YES;
    clBeconRegion.notifyEntryStateOnDisplay=YES;
}

-(void)initRegion
{
    NSUUID *uuid=[[NSUUID alloc]initWithUUIDString:UUID];
    clBeconRegion=[[CLBeaconRegion alloc]initWithProximityUUID:uuid identifier:@"BeaconExample"];

//    clBeconRegion=[[CLBeaconRegion alloc]initWithProximityUUID:uuid major:8983 minor:738
//                                                    identifier:@"aB"];
    //    clBeconRegion=[[CLBeaconRegion alloc]initWithProximityUUID:uuid major:8983 minor:728
    //                                                    identifier:@"bB"];
    clBeconRegion.notifyOnEntry=YES;
//    clBeconRegion.notifyOnExit=YES;
    clBeconRegion.notifyEntryStateOnDisplay=YES;

    [locManager startMonitoringForRegion:clBeconRegion];
}
-(void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region{
  NSLog(@"didStartMonitoringFor Region");

//    [locManager startRangingBeaconsInRegion:clBeconRegion];
    [locManager requestStateForRegion:clBeconRegion];

}
-(void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region{

    switch (state) {
        case CLRegionStateInside:
            [locManager startRangingBeaconsInRegion:clBeconRegion];
                        NSLog(@"Region Inside");
            break;
        case CLRegionStateOutside:
//            [locManager stopRangingBeaconsInRegion:clBeconRegion];
            NSLog(@"Region OutSide %ld",(long)state);
        case CLRegionStateUnknown:

        default:
            // stop ranging beacons, etc
            NSLog(@"Region unknown %ld",(long)state);
    }
}
-(void)locationManage:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region{
    NSLog(@"Entered Region");
    [locManager startRangingBeaconsInRegion:clBeconRegion];

    CLBeaconRegion *reg=(CLBeaconRegion *)region;
    [disObj login:[NSString stringWithFormat:@"%@", reg.major] :[NSString stringWithFormat:@"%@", reg.minor]];
    NSString *enterRegion=[NSString stringWithFormat:@"You ENTERED a Region %@",reg.minor];
    [self sendLocalNotificationWithMessage1:enterRegion];
}
-(void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region{

       CLBeaconRegion *reg=(CLBeaconRegion *)region;
        NSString *exit=[NSString stringWithFormat:@"You Exit a Region %@",reg.minor];
    [self sendLocalNotificationWithMessage1:exit];
    NSLog(@"Exit Region");
    [locManager stopRangingBeaconsInRegion:clBeconRegion];
}
-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region{}

检查didEnterRegion签名：你写了locationManage而不是locationManager

didEnterRegion未调用，但didExitRegion在目标C中调用
