Any way to have completionHandler style syntax using [facebook authorize] on iOS 5?

阅读更多关于 Any way to have completionHandler style syntax using [facebook authorize] on iOS 5?

The code below is trying to lazy login to Facebook right before posting a photo, but has an asynchronous problem. In the logs, the after isSessionValid block will appear before the fbDidLogin and then a facebookErrDomain error 10000 will happen ("OAuthException", "active access token must be used", etc). MyAppDelegate *appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate]; if (![appDelegate.facebook isSessionValid]) { [appDelegate.facebook authorize:[NSArray arrayWithObjects:@"publish_stream", @"user_photos", nil]]; } NSLog(@"after isSessionValid block"); NSData

问题 I can't seem to get my posts to work using the Facebook SDK for iOS. I am using the "startWithGraphPath:parameters:HTTPMethod:completionHandler:" function.

阅读更多关于 Random Facebook iOS SDK auth token invalidated by API

问题 I randomly get the following message when trying to access the graph from my iPhone using Facebook iOS SDK: response string: {"error":{"type":"OAuthException","message":"Error validating access token: The session was invalidated explicitly using an API call."}} I'm not sure why this is because I call the graph immediately after I login, so the token should be valid. Also, this happens randomly around 30% of the time. Does anyone know how to go about debugging this issue? 回答1: I've been

阅读更多关于 How to relaunch an app like facebook-ios-sdk does?

Question: I am actively looking in the source code on Github's facebook-ios-sdk project myself but I was wondering if anyone already knows how to relaunch an app that sent an iPhone user to Safari, such that the user can come back after some work has been finished? Example: When using facebook to login, the original app is relaunched after the facebook login page has authenticated the user. Motivation: I would like to be able to do the same for youtube videos without having to completely lose the user. I don't want to use the standard webview approach because I don't want to provide extra

I'm recently trying to update the Facebook SDK on our application. I had no worries following the steps fom the Upgrade guide by Facebook. I was able to compile without issues. However, when I quit XCode, reopen my project and try to recompile I get an error about ' FBAppCall ' (undeclared identifier). All others classes from the SDK are working except this one and ' FBDialogs '. I am able to solve those errors by deleting the Facebook framework and adding it again. But I must do it every time I quit XCode. I've tried to check or uncheck " Copy items into destination group's folder (if needed)
