Iphone : showing blank facebook login dialog

Question

I have integrated facebook sdk in iphone app. It was working fine. But, suddenly, it stopped showing "Facebook login page" in dialog, as it is shown in screenshot. I tried it with different facebook api key, secret and it worked fine, but its not working with my old api key, secret. Please help me in this.

Thank you.

Please check if your API keys and secrets are valid and not expired. — BornCoder, Aug 30 '12 at 03:14

I had this problem exactly the same with yours.

I managed to figure out that the user-agent I was setting is not recognized by facebook login dialog (which is a webview).

Facebook login dialog takes default user-agent, which should look like this: Mozilla/5.0 (iPhone Simulator; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/9A334. So leaving the user-agent default could be a good try.

Not sure if you still have this problem since this question has been a long while. Just to leave a message for who are facing this problem and are looking for a possible solution.
