Ok,I understand if you want to send app request to your friends than you should use FBSDKAppInviteContent.
Here is the code:
FBSDKAppInviteContent *content =[[FBSDKAppInviteContent alloc] init];
content.appLinkURL = [NSURL URLWithString:#"Your_App_Id"];
content.previewImageURL = [NSURL URLWithString:#"Your_app_previewimage"];
[FBSDKAppInviteDialog showWithContent:content
delegate:self];
Here for Your_App_Id please refer to this link.
And it's delegate methods:
- (void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didCompleteWithResults:(NSDictionary *)results{
if (results) {
}
}
- (void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didFailWithError:(NSError *)error{
if (error) {
NSString *message = error.userInfo[FBSDKErrorLocalizedDescriptionKey] ?:
#"There was a problem sending the invite, please try again later.";
NSString *title = error.userInfo[FBSDKErrorLocalizedTitleKey] ?: #"Oops!";
[[[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil] show];
}
}

Why don't you try FBSDKGameRequestContent(It will require Facebook SDK 4.0)?
Note: This will work only if your app category is Game in Facebook developer page.
Here is the code:
FBSDKGameRequestContent *gameRequestContent = [[FBSDKGameRequestContent alloc] init];
// Look at FBSDKGameRequestContent for futher optional properties
FBSDKGameRequestDialog *dialog = [[FBSDKGameRequestDialog alloc]init];
dialog.delegate = self;
dialog.content = gameRequestContent;
gameRequestContent.message = #"Become a Ninja!!!";
gameRequestContent.title = #"NinjaPan";
dialog.delegate = self;
dialog.content = gameRequestContent;
[dialog show];
And it's delegate methods:
- (void)gameRequestDialog:(FBSDKGameRequestDialog *)gameRequestDialog didCompleteWithResults:(NSDictionary *)results{
if (results) {
}
}
- (void)gameRequestDialog:(FBSDKGameRequestDialog *)gameRequestDialog didFailWithError:(NSError *)error{
if (error) {
NSLog(#"%#",error.localizedDescription);
}
}
- (void)gameRequestDialogDidCancel:(FBSDKGameRequestDialog *)gameRequestDialog{
NSLog(#"Cancelled by user");
}
