Tweets through ios simulator through my iphone app does not show up on my twtitter feed.

I connected a tweeting option in my iphone app (really simple one) but even though I connected my account when ever i tweet something it sends but doesnt show up in my twiiter feed.

This is my .h file.

#import <UIKit/UIKit.h>

@interface XYZViewController : UIViewController

@property (weak, nonatomic) IBOutlet UITextField *maintitle;

@property (weak, nonatomic) IBOutlet UITextField *numberone;

@property (weak, nonatomic) IBOutlet UITextField *dos;

@property (weak, nonatomic) IBOutlet UITextField *tres;

- (IBAction)tweetTapped:(id)sender;

@property (weak, nonatomic) IBOutlet UITextField *cutro;

@property (weak, nonatomic) IBOutlet UITextField *cindo;

@property (weak, nonatomic) IBOutlet UITextField *seis;

@property (weak, nonatomic) IBOutlet UITextField *seba;

@end

This is my .m file

#import "XYZViewController.h"
#import <Social/Social.h>

@interface XYZViewController ()
@end

@implementation XYZViewController

@synthesize numberone, dos, tres, cutro, cindo, seis, seba, maintitle;

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])

    SLComposeViewController *tweetSheet = [SLComposeViewController   
   composeViewControllerForServiceType:SLServiceTypeTwitter];
    [tweetSheet setInitialText:@"Tweeting from my own app! :)"];
    [self presentViewController:tweetSheet animated:YES completion:nil];
}
else
{
    UIAlertView *alertView = [[UIAlertView alloc]
                              initWithTitle:@"Sorry"
                              message:@"You can't send a tweet right now, make
  sure your device has an internet connection and you have at least one
  Twitter account setup"
                              delegate:self
                              cancelButtonTitle:@"OK"
                              otherButtonTitles:nil];
    [alertView show];
