ios - GoogleCloudMessaging 链接错误

Question

我需要在我的应用中使用 GoogleCloudMessaging。我通过 Cocoapods 安装了它。当我添加这部分代码时:

GLInstanceIDConfig *instanceIDConfig = [GGLInstanceIDConfig defaultConfig];
    instanceIDConfig.delegate = self;
    // Start the GGLInstanceID shared instance with the that config and request a registration
    // token to enable reception of notifications
    [[GGLInstanceID sharedInstance] startWithConfig:instanceIDConfig];
    _registrationOptions = @{kGGLInstanceIDRegisterAPNSOption:deviceToken,
                             kGGLInstanceIDAPNSServerTypeSandboxOption:@YES};
    [[GGLInstanceID sharedInstance] tokenWithAuthorizedEntity:GCMSSenderID
                                                        scope:kGGLInstanceIDScopeGCM
                                                      options:_registrationOptions
                                                      handler:_registrationHandler];

我有这些错误:

Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_GGLInstanceID", referenced from: objc-class-ref in AppDelegate.o "_OBJC_CLASS_$_GGLInstanceIDConfig", referenced from: objc-class-ref in AppDelegate.o "_kGGLInstanceIDAPNSServerTypeSandboxOption", referenced from: -[AppDelegate application:didRegisterForRemoteNotificationsWithDeviceToken:] in AppDelegate.o "_kGGLInstanceIDRegisterAPNSOption", referenced from: -[AppDelegate application:didRegisterForRemoteNotificationsWithDeviceToken:] in AppDelegate.o "_kGGLInstanceIDScopeGCM", referenced from: -[AppDelegate application:didRegisterForRemoteNotificationsWithDeviceToken:] in AppDelegate.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

项目设置:

-> 仅构建事件架构 - 是

-> Other Linked Flags 包含 $(inherited)

-> 部署目标 - 8.0

请帮帮我!提前致谢!

检查 4 件事:

1. 您尚未在您的项目中手动上传 GoogleCloudMessaging。如果有，删除它们并重新安装 pod。

2. 检查您的build设置中的链接器路径设置。在安装 pod 之前使用“$inherited”。

3. 重新安装 pod 后，使用 cmd + shift + k 清理您的项目，然后运行您的项目。

4. 仅构建事件架构 - 否，对于目标 - 是
