Signal Sigabart issue when switching from Viewcontroller to another view controller..using this code
i've created an app which loads another viewcontroller from main view controller.example from viewcontroller 1 to viewcontroller2...in viewcontroller1 if button is pressed it needs to load viewcontroller2.and in viewcontroller2 i got icarousel view too..Here is my code 

     -(IBAction)showcoll:(id)sender{
    
    CollectionsViewController *sec=[[CollectionsViewController alloc]initWithNibName:Nil bundle:Nil];
    sec.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;
    
    NSLog(@"hi");
    [self presentModalViewController:sec animated:YES];
    }

     - (void)viewDidLoad
     {
    [super viewDidLoad];
	// Do any additional setup after loading the view, typically from a nib.
    CGRect splashFrame =splash.frame;
    splashFrame.origin.x = self.view.bounds.size.width;    
    
    [UIView animateWithDuration:3
                          delay:1.0
                        options: UIViewAnimationCurveEaseOut
                     animations:^{
                         splash.frame = splashFrame;
                         
                     } 
                     completion:^(BOOL finished){
                         NSLog(@"Done!");
                     }];
    [self.view addSubview: splash];
