Answer 1

Today with the 3.11 version of the facebook SDK you should use this in order to send an app request to a specific friend.

NSString *facebookID = @"YOUR_FRIEND_FACEBOOK_ID"
NSMutableDictionary* params =
[NSMutableDictionary dictionaryWithObject:facebookID forKey:@"to"];

NSString *message = @"SOME_MESSAGE";
NSString *title = @"TITLE";


FBSession *facebookSession = [PFFacebookUtils session]; //You may changed this if you are not using parse.com

[FBWebDialogs presentRequestsDialogModallyWithSession:facebookSession
                                              message:message
                                                title:title
                                           parameters:params handler:
 ^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
 {

 }];

Make sure your facebook app id is same in both developer page and info in xcode next, enable sandbox mode and must fill canvas url [under app on facebook category] in developer page.

NSString *facebookID = @"Your friend facebook id";;
    NSMutableDictionary* params =
    [NSMutableDictionary dictionaryWithObject:facebookID forKey:@"to"];

    NSString *message = @"SOME_MESSAGE";
    NSString *title = @"TITLE";

    [FBWebDialogs presentRequestsDialogModallyWithSession:nil
                  message:message
                title:title
                parameters:params handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
                        if (error)
                    {
                    // Case A: Error launching the dialog or sending request.
                        NSLog(@"Error sending request.");
                    }
                    else
                    {
                        if (result == FBWebDialogResultDialogNotCompleted)
                    {
                    // Case B: User clicked the "x" icon
                        NSLog(@"User canceled request.");
                    }
                    else
                    {
                        NSLog(@"Request Sent. %@", params);
                    }
        }}];

You can either use the share dialog to share the Link to download the app to the user's wall, or write custom UI elements and use API Calls to build your own sharing module. Trying using a Facebook iOS SDK to simplify the process or you will have a lot of work to do.

It's simple you can just write the below code for personalised message and also you can easily select the friend's to whom the request should be sent, it's an straight forward and powerful method.

 [FBWebDialogs
 presentRequestsDialogModallyWithSession:nil
 message:NSLocalizedString(@"FBinviteMessage", nil)
 title:nil
 parameters:nil
 handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {}
];

Just add this six line of code to your Button action method, then the rest will be done by the IOS & FaceBook Inbuilt framework :)

[FBWebDialogs
 presentRequestsDialogModallyWithSession:nil
 message:@"YOUR_MESSAGE_HERE"
 title:nil
 parameters:nil
 handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
     if (error) {
         // Error launching the dialog or sending the request.
         NSLog(@"Error sending request.");
     } else {
         if (result == FBWebDialogResultDialogNotCompleted) {
             // User clicked the "x" icon
             NSLog(@"User canceled request.");
         } else {
             // Handle the send request callback
             NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
             if (![urlParams valueForKey:@"request"]) {
                 // User clicked the Cancel button
                 NSLog(@"User canceled request.");
             } else {
                 // User clicked the Send button
                 NSString *requestID = [urlParams valueForKey:@"request"];
                 NSLog(@"Request ID: %@", requestID);
             }
         }
     }
}];
