GMSPlacesClient currentPlaceWithCallback：花费太多时间

Question

我正在使用Google为iOS设置api。我已经实现了当前的地方功能。这是代码（它与指南中提供的谷歌相同）。

[_placesClient currentPlaceWithCallback:^(GMSPlaceLikelihoodList *likelihoodList, NSError *error) {
  if (error != nil) {
    NSLog(@"Current Place error %@", [error localizedDescription]);
    return;
  }

  for (GMSPlaceLikelihood *likelihood in likelihoodList.likelihoods) {
    GMSPlace* place = likelihood.place;
    NSLog(@"Current Place name %@ at likelihood %g", place.name, likelihood.likelihood);
    NSLog(@"Current Place address %@", place.formattedAddress);
    NSLog(@"Current Place attributions %@", place.attributions);
    NSLog(@"Current PlaceID %@", place.placeID);
  }

}];

但执行回调大约需要3-4分钟。我已经按照他们在指南中提供的所有步骤进行了操作。
