问题
i am working on integrating fb login to our own application. Problem is example i downloaded it's working fine,when use the code in my project its getting error
Note: I Checked the fbapplicationid in .plist and in the url page they both are same.
回答1:
After User authorizes the App. Facebook request the browser to launch the app that requested access. That url is based on App's url schemes ( defined in App's plist). So you need to double check that. Safari shows error because it cannot find the url scheme -> Invalid URL
it is of the form like fb<myAppId>.
After that do a clean build of project and run.
