iOS GoogleMaps SDK错误：“：无法识别的select器发送”
我遵循开始使用谷歌地图的每一个步骤ios，我做了一切正常，但在每一个我尝试的例子，模拟器开始问我是否要打开GPS，然后，它会引发错误：

注意：在我的ViewController的加载视图之前抛出错误。
你可能想看看这个问题： iOS 5.1的objectForKeyedSubscript：崩溃
顺便说一句，你正在使用的Xcode的版本是什么？ 什么是你使用的iOS SDK版本？
使用Google Maps SDK for iOS开发应用程序需要以下内容：
- Xcode 4.5或更高版本。
- iOS SDK 6.0或更高版本。
使用iOS版Google地图SDK的应用程序可以在iOS 5.1及更高版本上运行。
你是否在步骤7中添加了-ObjC标志？
我有同样的期待，并通过在构build设置中添加-ObjC到其他链接器标志来解决
其他人提到了Google文档中的以下部分
select你的项目，而不是一个特定的目标，并打开生成设置选项卡。 在Other Linker Flags部分中，添加-ObjC。 如果这些设置不可见，请将“生成设置”栏中的filter从“基本”更改为“全部”。
然而，直到我将-ObjC标志添加到项目的“其他链接标志”部分，而不是目标的“其他链接标志”部分，才能够解决无法识别的select器错误。
