ios - 如何使用 use_frameworks cocoa pods 和 Google SDK

Question

我正在构建一个简单的 iOS (Swift) 应用程序 - 它会呈现 map 并在其上绘制标记。

当我的 Podfile 运行时它工作正常

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.1'

pod 'GoogleMaps'

但是当我把它改成这个时(注意 use_frameworks!)

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.1'
use_frameworks!

pod 'GoogleMaps'
pod 'Alamofire', '~> 1.3'

我收到以下错误。

错误:

CoreData: warning: Unable to load class named 'GMSCachedObject' for entity 'GMSCachedObject'.  Class not found, using default NSManagedObject instead.

我应该做什么不同的事情？

Answer 1

After some debugging I realised that the issue arose when attempting to use both ObjectiveC pods (such as GoogleMapsSDK) and Swift libraries such as Alamofire.

A really simple solution is to add -ObjC to your linkers in XCode which will tell it to compile the ObjectiveC pods.

After adding the linker everything compiles and I’m able to use the two pods in unison.
