我正在努力在我的代码中链接ALAssetsLibrary.
我已经在Google上搜索了很多内容,并且在最后一个点上进行了多个教程,但我仍然是我开始的地方.

我有一个网页,我想使用地方自动完成以及带标记的谷歌地图.用户可以搜索到位自动填充的地址.标记的Lat-long数据来自DB,这不会改变.问题是地图是否有效或是否存在自动填充,但两者都不是,问题与回调有关.
从谷歌文档中,我在单独的API调用中包含了两个回调:
<script src="https://maps.googleapis.com/maps/api/js?key=[API KEY]&signed_in=true&libraries=places&callback=initAutocomplete" async defer></script>
<script async defer src="https://maps.googleapis.com/maps/api/js?key=[API KEY]&callback=initMap"></script>
但这会在控制台上引发错误,并且没有任何效果.
错误:您已在此页面上多次添加Google Maps API.这可能会导致意外错误.
我的问题是:如何将多个回调传递给Google API？
