我正在尝试安装Google maps SDK，并且在运行时遇到此错误：

I am trying to install the Google maps SDK and I am running through this error when running:

推荐答案

当我升级使用手动安装的旧版Google地图SDK的应用时，我注意到以下更改：

I noticed the following changes when I upgraded an app that was using the older Google maps SDK that had been installed manually:

• 需要链接到 CoreBluetooth.framework 和 Accelerate.framework 在Build阶段 - > Link Bundle with Libraries。


• 其他链接器标志下的 -all_load 标志将导致重复符号错误。 （改为使用 -ObjC 。）

• Need to link to CoreBluetooth.framework and Accelerate.framework in Build Phases -> Link Bundle with Libraries.
• The -all_load flag under "Other Linker Flags" will cause "duplicate symbol" errors. (Use -ObjC instead.)

如果您使用CocoaPods安装方法（根据他们当前的说明） ），它应该采用所需的框架，但它仍然会被 -all_load 弄乱。

If you use the CocoaPods method of installation (per their current instructions), it should take of the required frameworks but it'll still get messed up by -all_load.
