我有以下代码，可以在应用终止时完美运行。
-(void)beaconManager:(id)manager didEnterRegion:(CLBeaconRegion *)region{
UILocalNotification *notification = [UILocalNotification new];
notification.alertBody = @"TEST NOTIFICATION";
notification.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] presentLocalNotificationNow:notification];
}
但是当我执行以下操作时：
-(void) createTestNotification {
UILocalNotification *notification = [UILocalNotification new];
notification.alertBody = @"TEST";
notification.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] presentLocalNotificationNow:notification];
}
-(void)beaconManager:(id)manager didEnterRegion:(CLBeaconRegion *)region{
[self createTestNotification];
}
它不起作用？我只将我的代码移到外面没有别的？我知道当didEnterRegion被调用时应用程序只有5秒，但调用此方法不会花费这个时间吗？
更新1：
我刚发现区域 didEnterRegion返回的是我开始监控而不是属于信标的那个 >该应用程序刚看到它。我将使用此区域来获取我的自定义消息取决于此区域的主要和次要。
但是在我的情况下这是不可能的，所以当didEnterRegion被调用时我开始范围，然后在didRangeBeacons中返回信标的数组>我从 localDataBase ＆＃34;取决于Major＆amp; minor＆＃34;
这是我的代码： 此代码在后台的app中工作并获得通知但是当app close永远不会收到通知？ < / p>
-(void)beaconManager:(id)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region{
[self handelBeaconsNotification:beacons];
}
-(NSString *) getBeaconFromLocalData:(NSNumber *)regionMajor andRegionMin:(NSNumber *)regionMinor{
PFQuery *query = [PFQuery queryWithClassName:@"Beacons"];
NSArray *allRegions_id = [[NSArray alloc] initWithObjects:[NSNumber numberWithInt:1], nil];
[query whereKey:@"region_id" containedIn:allRegions_id];
NSLog(@"%@",regionMajor);
NSLog(@"%@",regionMinor);
[query whereKey:@"major" equalTo:regionMajor];
[query whereKey:@"minor" equalTo:regionMinor];
[query fromLocalDatastore];
NSArray *data = [query findObjects];
return [[data objectAtIndex:0] valueForKey:@"enter_message"];
}
-(void) handelBeaconsNotification:(NSArray *)beaconsArray{
for (int i = 0 ; i<beaconsArray.count; i++) {
NSString *currentBeaconKey = [NSString stringWithFormat:@"%@-%@",[beaconsArray[i] major],[beaconsArray[i] minor]];
if ([beaconsDictionary valueForKey:currentBeaconKey] == nil) {
NSMutableDictionary *dateDic = [[NSMutableDictionary alloc] init];
[dateDic setValue:[NSDate date] forKey:@"StartVisit"];
[dateDic setValue:nil forKey:@"EndVisit"];
[beaconsDictionary setValue:dateDic forKey:currentBeaconKey];
UILocalNotification *notification = [UILocalNotification new];
notification.alertBody = [self getBeaconFromLocalData:[beaconsArray[i] major] andRegionMin:[beaconsArray[i] minor]];
notification.soundName = UILocalNotificationDefaultSoundName;
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:2];
notification.timeZone = [NSTimeZone defaultTimeZone];
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
}
}
更新2：
我只是将日志添加到didEnterRegion和didRangeBeacons，以确定只显示来自didEnterRegion的 NSLog ，然后该应用看起来像 崩溃 ，didRangeBeacons的日志未显示

mmm我认为您正在使用空区域变量，因此请确保正确发送它并且不要为startRanging方法使用空变量。
当您的应用关闭时，所有变量都将被终止，因此请确保您将其传递给非空。
