Question

我正在使用Kontakt信标和iOS SDK，我的代码一次又一次地在部分崩溃以获取我的信标的动作

Kontakt SDK文档为here

- (void)locationManager:(KTKLocationManager *)locationManager
        didRangeBeacons:(NSArray *)beacons {

    NSMutableDictionary *beaconsData = [NSMutableDictionary new];
    for (CLBeacon *beacon in beacons) {
        KTKBeacon *beaconData = [self _getDataForBeacon:beacon];
        if (beaconData) [beaconsData setObject:beaconData forKey:beacon];
    }
    self.actionManager = [KTKActionManager new];
    self.actionManager.delegate = self;
    [self.actionManager processBeacons:beacons withData:beaconsData];
}

获取信标数据的方法

-(NSDictionary *)_getDataForBeacon:beacon
{
    NSLog(@"%@",beacon);
    NSData * jsonData = [NSData dataWithContentsOfURL:[NSURL
                                                       URLWithString:@"****"]];
    NSError * error=nil;
    NSDictionary *dic = [NSJSONSerialization
                         JSONObjectWithData:jsonData options:kNilOptions error:&error];
    NSLog(@"%@",dic);

    NSArray *array = [NSArray arrayWithObject:beacon];
    NSDictionary *data = [self.client getActionsForBeacons:array changedSince:0 error:&error]; //##It crashes here##
    NSLog(@"%@",data);

    return data;
}

dic 字典

的内容

你可能已经解决了这个问题，因为为时已晚。但下面是获取信标数据所需的完整代码，对于遇到此问题的其他人可能会有用。

-(KTKBeacon *)_getDataForBeacon:(CLBeacon *)beacon
{
    NSString *strURL = [NSString stringWithFormat:@"https://api.kontakt.io/beacon?proximity=%@&major=%@&minor=%@",
                        [beacon.proximityUUID UUIDString],
                        beacon.major,beacon.minor];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:strURL]];
    [request setValue:@"YOUR_API_KEY" forHTTPHeaderField:@"Api-Key"];
    [request setValue:@"application/vnd.com.kontakt+json; version=2" forHTTPHeaderField:@"Accept"];
    NSData *jsonData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSError * error=nil;
    NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
    NSLog(@"%@",dic);
    KTKBeacon *newBeacon = [[KTKBeacon alloc] initWithDictionary:dic];
    return newBeacon;
}

什么发送beaconsData到getActionsForBeacons（Kontakt beacons）
