高德地圖逆地理編碼結果沒有數據，是什麼問題？

今天試了下逆地理編碼功能，相關代碼如下：
-(void)initMapS{
if (!self.mapS) {
self.mapS = [[AMapSearchAPI alloc] initWithSearchKey:GAODEMAPKEY Delegate:self];
}
}

//初始化逆地理編碼
-(AMapReGeocodeSearchRequest *)initializeRegeoReqWithLatitude:(double)latitude longitude:(double)longitude{
AMapReGeocodeSearchRequest *regeoReq = [[AMapReGeocodeSearchRequest alloc]init];
regeoReq.searchType = AMapSearchType_Geocode;
regeoReq.location = [AMapGeoPoint locationWithLatitude:latitude longitude:longitude];
regeoReq.requireExtension = YES;
return regeoReq;
}
// 開始逆地理編碼
-(void)beginGeoCodeWithSearchReq:(AMapReGeocodeSearchRequest *)searchReq{
if (searchReq) {
[self initMapS];
[self.mapS AMapReGoecodeSearch:searchReq];
}
}

-(void)onReGeocodeSearchDone:(AMapReGeocodeSearchRequest *)request response:(AMapReGeocodeSearchResponse *)response{
if (self.isReoGeo) {
self.isReoGeo = NO;
}

if(response.regeocode != nil){
    NSString *result = [NSString stringWithFormat:@"%@",response.regeocode.addressComponent];
    NSLog(@"逆地理編碼結果:%@",result);
    if(result && result.length > 0){
        self.addCL.text = result;
    }
}

}
最終輸出的結果卻什麼都沒有：
逆地理編碼結果:{province: , city: , district: , township: , neighborhood: , building: , citycode: , adcode: , streetNumber: {street: , number: , location: {0.000000, 0.000000}, distance: 0, direction: }, businessAreas: }
請問這是什麼問題？

最佳回答：

沒有獲取到當前位置的經緯度。
