-(void)viewDidLoad


    expandiView = [[UIView alloc] initWithFrame:CGRectMake(137, 269, 30, 2
                                                            )];
    expandiView.backgroundColor = [UIColor redColor];
    [self.view addSubview:expandiView];
    expandiView.hidden=YES;



-(IBAction)Expand:(id)sender 

    expandiView.hidden=NO;


    [UIView animateWithDuration:0.5f
                     animations:^

                         expandiView.frame = CGRectMake(60, 269, 200, 2);
                     
                     completion:^(BOOL finished) 
                         [UIView animateWithDuration:1
                                          animations:^
                                              expandiView.frame = CGRectMake(60, 269, 200, 100);

                                          ];
                     ];







-(IBAction)collapse:(id)sender 



    [UIView animateWithDuration:0.5f
                     animations:^
                         expandiView.frame = CGRectMake(60, 269, 200, 2);

                     
                     completion:^(BOOL finished) 
          [UIView animateWithDuration:0.5f animations:^
                             expandiView.frame = CGRectMake(137, 269, 30, 2);
                          completion:^(BOOL finished) 
                             expandiView.hidden=YES;
                         ];
                     ];
