Show test code

-(void)showTest
{
    NSLog(@"Show Test");
    lbl.text=@"";
    logOut.hidden=YES;
  //  [self showWithLabelMixed];
 FormViewController *formViewController =[[FormViewController alloc]initWithNibName:@"FormViewController" bundle:nil];
    formViewController.userId=fbUserId;
    [formViewController.userId retain];


    formViewController.sex=[fbResult objectForKey:@"sex"];
    [formViewController.sex retain];

    formViewController.country=[[fbResult objectForKey:@"current_location"]objectForKey:@"country"];
    [formViewController.country retain];

    formViewController.city=[[fbResult objectForKey:@"current_location"]objectForKey:@"city"];
    [formViewController.city retain];

    formViewController.birthDate=[fbResult objectForKey:@"birthday_date"];
    [formViewController.birthDate retain];

    formViewController.userImage=imageFb;
    [formViewController.userImage retain];

    [self presentModalViewController:formViewController animated:YES];

   // [self.tabBarController pushViewController:formViewController animated:YES];


}

the line 447 in firstViewControlelr is

formViewController.country=[[fbResult objectForKey:@"current_location"]objectForKey:@"country"];

But there is no line 447 on FormViewController

In your showTest method at line 447:

[FirstViewController showTest] (FirstViewController.m:447)

You are calling a method on an object that doesn't accept it:

-[NSObject(NSObject) doesNotRecognizeSelector:] + 96

Could you please edit your question to show us code from the showTest method?

Edit: Updating question to reflect new information

Remove the following lines of code:

[formViewController.userId retain];
[formViewController.sex retain];
[formViewController.country retain];
[formViewController.city retain];
[formViewController.birthDate retain];
[formViewController.userImage retain];

I'm not sure if this is what is causing your bug because you haven't indicated which is the line number that is causing it in this sample. But, what you are doing here is calling retain on values that have already been set by a property setter, and in the case of an object is usually set already.
