- I've looked through sample code on Facebook here:https://developers.facebook.com/docs/howtos/feed-dialog-using-ios-sdk/
- and reviewed the class reference: https://developers.facebook.com/docs/reference/ios/3.2/class/FBWebDialogs/#presentDialogModallyWithSession%3Adialog%3Aparameters%3Ahandler%3A
Is there documentation on the full set of parameters I can pass FWWebDialogs? Can I set the text within the "say something" text (I know you can set the caption and description).
The parameters listed at the bottom of https://developers.facebook.com/docs/reference/dialogs/feed/ are all allowed to be passed into the webdialog. No you can't set the text within the say something field. If you are using the native iOS 6 share controls you can set the text, however the user can change it.
