Question

我从https://github.com/ResultsDirect/LinkedIn-iPhone下载了源代码。演示工作正常，并尝试在我的应用程序中使用。

我已按照post ...

中提到的所有步骤进行了操作

但我收到了错误

"_OBJC_CLASS_$_RDLinkedInEngine", referenced from:
"_OBJC_CLASS_$_RDLinkedInAuthorizationController", referenced from:

当我评论RDLinkedInEngine和RDLinkedInAuthorizationController的行时，会删除错误

- (void)loadView {
    [super loadView];
//    rdEngine = [[RDLinkedInEngine engineWithConsumerKey:kOAuthConsumerKey consumerSecret:kOAuthConsumerSecret delegate:self] retain];
}
- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
//    if( !rdHasAppeared ) {
//        UIViewController* controller = [RDLinkedInAuthorizationController authorizationControllerWithEngine:rdEngine delegate:self];
//        if( controller ) {
//            [self presentModalViewController:controller animated:YES];
//            rdHasAppeared = YES;
//        }
//        else {
//            NSLog(@"Already authenticated");
//        }
//    }
}

我的应用程序我已经从源https://github.com/bengottlieb/Twitter-OAuth-iPhone集成了MGTwitterEngine，这是好的。

最有可能你需要从linkedIn源添加一些静态库（.a文件）...或src文件夹...

Answer 2

我遇到了同样的问题。可以通过设置Library Dependency来解决。选择项目目标，然后选择常规。在那里你会发现直接依赖。从LinkedInClientLibrary.xcodeProject

添加LinkedInLibrary
