我按照getting started的每个步骤使用谷歌地图为ios，我做了一切正常但在我尝试的每个例子中，模拟器开始询问我是否要打开GPS，之后，它会抛出错误：

答案 0 :(得分：6)
您是否在说明的第7步中添加了-ObjC标志？
答案 1 :(得分：1)
您可能需要查看此问题：objectForKeyedSubscript: crash on iOS 5.1
顺便问一下，您使用的Xcode版本是什么？你正在使用的iOS SDK版本是什么？
使用适用于iOS的Google Maps SDK开发应用程序需要以下内容：
使用适用于iOS的Google Maps SDK的应用程序适用于iOS 5.1及更高版本。
答案 2 :(得分：1)
我有同样的期望，它通过在构建设置中将-ObjeCT添加到其他链接器标志来解决
答案 3 :(得分：1)
其他人在Google的文档
中提到了以下部分选择您的项目，而不是特定目标，然后打开“构建设置”选项卡。在Other Linker Flags部分中，添加-ObjC。如果看不到这些设置，请将Build Settings栏中的过滤器从Basic更改为All。
然而，直到我将-ObjC标志添加到我的项目'Other Linker Flags'部分，而不是目标'Other Linker Flags'部分，才能解决无法识别的选择器错误。
