Answer 1

just try this

 [FBMessageHandler displayAlertMessageWithOkButton:NSLocalizedString(@"All text fields are mandatory. Please fill the complete form and then submit!", @"incomplete reg form") backgroundImage:nil tag:0 andDelegate:self addInQueue:NO andParentViewController:self];

into

    [FBMessageHandler displayAlertMessageWithOkButton:NSLocalizedString(@"All text fields are mandatory. Please fill the complete form and then submit!, incomplete reg form") backgroundImage:nil tag:0 andDelegate:self addInQueue:NO andParentViewController:self];

choice no 2

    NSString *msgstr=[NSString stringWithFormat:@"All text fields are mandatory. Please fill the complete form and then submit!,incomplete reg form"];


   [FBMessageHandler displayAlertMessageWithOkButton:msgstr backgroundImage:nil tag:0 andDelegate:self addInQueue:NO andParentViewController:self];
