使用未解析的标识符"GMSServices" [英] Use of Unresolved Identifier 'GMSServices'

问题描述

我正在使用Xcode 7.1，部署目标是iOS 9.1.该应用程序是"AreaCalculator"，它是用Swift编写的.我做了以下步骤来设置框架并导入地图:

I am using Xcode 7.1 and the deployment target is iOS 9.1. The app is "AreaCalculator" and it was written in Swift. I did following to set up the framework and import the map:

1. $ sudo gem install cocoapods

1. $ sudo gem install cocoapods

"AreaCalculator"下的$ touch Podfile

under "AreaCalculator" $ touch Podfile

在我放入的Podfile中:

in Podfile I put:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.1'
pod 'GoogleMaps'

$ pod安装

$ pod install

在终端机中:

[！]无法加载插件/Library/Ruby/Gems/2.0.0/gems/cocoapods-try-release-fix-0.1.2的规范 更新本地规格存储库 分析依赖关系 下载依赖项 安装GoogleMaps(1.10.5) 生成豆荚项目 整合客户项目

[！]从现在开始，请关闭任何当前的Xcode会话并对该项目使用AreaCalculator.xcworkspace. 发送统计信息 吊舱安装完成！ Podfile有1个依赖项，总共1个依赖项 吊舱已安装.

[!] Please close any current Xcode sessions and use AreaCalculator.xcworkspace for this project from now on. Sending stats Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.

此后，我在导航器中选择了AreaCalculator文件夹. 并选择File \ New \ File…，然后选择iOS \ Source \ Objective-C 文件模板并创建了一个桥接文件:
"AreaCalculator-Bridging-Header.h".

After that, I selected the AreaCalculator folder in the Navigator and select File\New\File…, then choose the iOS\Source\Objective-C File template and created a Bridging file:
"AreaCalculator-Bridging-Header.h".

• #import GoogleMaps/GoogleMaps.h

然后在链接二进制文件与库"中添加"GoogleMaps.framework". 并且"GoogleMaps.framwork"和"GoogleMaps.bundle"都位于 Pods文件夹.

Then I add "GoogleMaps.framework" in "Link Binary With Libraries". And both "GoogleMaps.framwork" and ""GoogleMaps.bundle" are in the Pods folder.

完成所有这些操作后，在AppDelegate.swift中，我输入:

After all those done, in the AppDelegate.swift, I put:

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    let googleMapsApiKey = "MY_GOOGLE_IOS_API_KEY"

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.
        GMSServices.provideAPIKey(googleMapsApiKey)
        return true
    }
}

但是，编译器向我显示了一个错误使用未解析的标识符'GMSServices'".

However, the compiler showed me an error "Use of Unresolved Identifier 'GMSServices' ".

我不知道我在哪里做错了?有人可以帮忙吗?

I have no idea where I did wrong? Anyone can help?

谢谢！

推荐答案

我已经通过在AppDelegate.swift中导入GoogleMaps"解决了该问题.

I have solved the problem by "import GoogleMaps" in the AppDelegate.swift.
