问题
I have download the source from https://github.com/ResultsDirect/LinkedIn-iPhone . Demo working fine, and try to use in my application.
I have followed all the steps already whatever required as mention here in post ...
But I have getting the error
"_OBJC_CLASS_$_RDLinkedInEngine", referenced from:
"_OBJC_CLASS_$_RDLinkedInAuthorizationController", referenced from:
When I comment the lines of RDLinkedInEngine and RDLinkedInAuthorizationController then error are removed
- (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");
// }
// }
}
I my application I have already integrated MGTwitterEngine from source https://github.com/bengottlieb/Twitter-OAuth-iPhone Which is wokring ok.

回答1:
most probably you need to add some static library (.a file)... or src folder itself from linkedIn source...
回答2:
I have gone through the same issue. It can be solved by setting Library Dependency. Select project target and then select general. There you will find Direct dependencies. Add LinkedInLibrary from LinkedInClientLibrary.xcodeProject
