Facebook request is not sending on all devices? - ios

Question

I wrote code
- (void)sendRequest {
NSLog(#"SEND REQUEST ");
// Display the requests dialog
[FBWebDialogs
presentRequestsDialogModallyWithSession:nil
message:#"www.demoapp.com"
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.");
[FBSession.activeSession closeAndClearTokenInformation];
[FBSession.activeSession close];
[FBSession setActiveSession:nil];
} else {
if (result == FBWebDialogResultDialogNotCompleted) {
// User clicked the "x" icon
NSLog(#"User canceled request.");
[FBSession.activeSession closeAndClearTokenInformation];
[FBSession.activeSession close];
[FBSession setActiveSession:nil];
} 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.");
[FBSession.activeSession closeAndClearTokenInformation];
[FBSession.activeSession close];
[FBSession setActiveSession:nil];
} else {
// User clicked the Send button
NSString *requestID = [urlParams valueForKey:#"request"];
NSLog(#"Request ID: %#", requestID);
[FBSession.activeSession closeAndClearTokenInformation];
[FBSession.activeSession close];
[FBSession setActiveSession:nil];
}
}
}
}];
}
- (NSDictionary*)parseURLParams:(NSString *)query {
NSArray *pairs = [query componentsSeparatedByString:#"&"];
NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
for (NSString *pair in pairs) {
NSArray *kv = [pair componentsSeparatedByString:#"="];
NSString *val =
[kv[1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
params[kv[0]] = val;
}
return params;
}
and calling it like
- (void)sendRequestButtonAction {
NSLog(#"sendRequestButtonAction");
AppDelegate *appDelegate =
(AppDelegate *) [[UIApplication sharedApplication] delegate];
if (FBSession.activeSession.isOpen) {
[appDelegate sendRequest];
}
}
I am sending from iPhone simulator and receiving in iPhone device and Android Device, but I am unable to receive in iPad,
I am amazed and cannot find solution at my end.
Please help
