问题
I'm using the Facebook SDK in an iOS app. I'm logging in fine, pulling in friends lists, etc.
I've added code to send a request:
[FBWebDialogs
presentRequestsDialogModallyWithSession:session
message:@"Message"
title:@"Title"
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
// view cleanup here
}];
The session is the FBSession stored in the class handling login. The params are suggestions, an array of friends to include. The issue described below occurs equally if params is nil (in which case the list shows all friends).
When I call the dialog, this is what appears:
Note that the "Message" text is missing, as is the entire Message block shown on the various Facebook documentation pages such as https://developers.facebook.com/docs/ios/ios-sdk-games/requests/.
I'm using Facebook SDK 3.7.1, the latest version as of this posting. The screenshot above is from the Simulator using a Facebook Test User account. The same issues occur on a device using a "real" Facebook account.

Apparently, this is "By Design"!! :(

I'm seeing the same issue. It appears to be a very recent development, as previously the dialog did show the message preview. I also noticed that the dialog does show the message preview if I specify the 'to' parameter; the message preview is missing only if I omit the 'to' parameter so that the dialog shows all the user's friends. Unfortunately I don't have a solution, but I wanted to share these additional observations if it helps get closer to the solution.
