【中文标题】OSX链接错误的Fabric Answers

【英文标题】：Fabric Answers for OSX link error

【问题描述】：

尝试在 OSX 平台上使用刚刚公布的 Answers 框架：

pod 'Fabric'
pod 'Answers'
pod 'Crashlytics'

#import <Fabric/Fabric.h>
#import <Answers/Answers.h>
#import <Crashlytics/Crashlytics.h>

[Fabric with:@[[Crashlytics class], [Answers class]]];

得到一堆错误：

...
duplicate symbol _OBJC_METACLASS_$_CLSAnswersInviteEvent in:
/Users/k06a/Projects/UXMaterial/Pods/Answers/OSX/Answers.framework/Answers(CLSAnswersInviteEvent.o)
/Users/k06a/Projects/UXMaterial/Pods/Crashlytics/OSX/Crashlytics.framework/Crashlytics(CLSAnswersInviteEvent.o)
ld: 200 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

【参考方案1】：

那是因为Crashlytics 框架内部已经包含Answers 框架。你只需要这样做：

Pod 文件：

pod 'Fabric'
pod 'Crashlytics'

您的 AppDelegate.m：

#import <Fabric/Fabric.h>
#import <Crashlytics/Answers.h>
#import <Crashlytics/Crashlytics.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
    ...
    [Fabric with:@[[Crashlytics class], [Answers class]]];
    ...

【讨论】：

对于 swift 仅导入 Fabric 和 Crashlytics，因为 Answers 对象包含在 Crashlytics 中:)
