尝试将LinkedIn集成到iPhone应用程序中

Question

我已经从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。

我已经按照帖子中的要求进行了所有步骤...

但是我得到了错误

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

当我评论RDLinkedInEngine和RDLinkedInAuthorizationController的行时，错误将被消除

- (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");
//        }
//    }
}

在我的应用程序中，我已经集成了来自源https://github.com/bengottlieb/Twitter-OAuth-iPhone的MGTwitterEngine，可以正常运行。

Answer 1

您最有可能需要添加一些静态库（.a文件）...或来自linkedIn源的src文件夹本身...

Answer 2

我经历了同样的问题。 可以通过设置库依赖来解决。 选择项目目标，然后选择常规。 在那里您将找到直接依赖项。 从LinkedInClientLibrary.xcodeProject添加LinkedInLibrary
