阅读更多关于 og:image ignored when sharing link, although accepted in linter

I want to share a link to my own website on Facebook, so I added the necessary og: tags to the <head> section. Checked it in the linter, and it displays everything I want it to display. When I actually want to share it in the newsfeed (as in copy and paste the link into the status formular), the image is ignored. Here's a sample link: http://iamschulz.de/video/4 Does it break the image size requirements? If so it'll still be detected by the debug tool, but won't actually be rendered in the news feed Images must be at least 50 pixels by 50 pixels. Square images work best, but you are allowed to

Use Facebook API with Objective C to find random Facebook user image

阅读更多关于 Use Facebook API with Objective C to find random Facebook user image

I am building an app that returns a random Facebook profile picture. So far I have the code below generating a random profile ID which sometimes does return a real profile but sometimes doesnt and just shows the generic blue Facebook face. When I use the given number on the actual website graph API it just returns false. My question is how would I put the code in so that if the random number generated returns a false profile, it just keeps generating a new random number until a real profile is returned, thus a real picture? Thanks in advance @implementation FacebookPicturesViewController -

Some pages of blogspot.com do not contain open graph tags, but Facebook Object Debugger still parse the open graph properties correctly. How does it get the open graph information?

阅读更多关于 ios facebook sdk v3.11 share dialog post button disabled

I was following the tutorial for facebook sdk for ios, specially using open graph to attach an image and tag friends (which social framework can't do directly). So I was following this tutorial and this sample app, FBOGSampleSD. https://developers.facebook.com/docs/ios/open-graph#sharedialog However my post button in the share dialog is always disabled. (grey out) Has anyone encountered this before? I am working with Xcode 5 and testing on ios7 device. Regards, Jin I think I figure this out. Your share button might be disabled because you didn't finish the Facebook app configuration, or it
