I have an application that uses a Tab Bar for control. In my thirdviewcontroller I have a webview that I would like to be able to program so that people can connect with facebook, and publish the link the webview is on to their facebook wall. I originally tested just the FBConnect without a webview present, and it worked fine. Afterwards, I added the UIWebView. It will build, but when the UIWebView is present, the FBConnect button will not appear. Here is my .h and .m codes.
.h:
.m:
UPDATE:
Ok I have it partially solved. Apparently I didn't get very much sleep last night and I have no idea why I did an awakefromnib and viewdidload statements. I moved
into the viewdidload, and the FBConnect button will now show. I can login, but when it tries to pull up the publish to wall part, it crashes. Here is what I have for the code for that part.
What I want it to do is to post a link of the current URL the user is on. I thought that setting up the NSString in the view did load and then setting the dialog.attachment to that NSString would work, but it constantly crashes. Any ideas?
