when iam click on download button it takes long time to goto next screen
===

I am new to iphone,I have a small doubt.I am working on audioPlayer project here In my screen I have a button download 
this is the screen that is ![my initial screen having an download button in top right corner][1]


when we click download this code executes


- (IBAction)gotoProgressViewController:(id)sender {
    @try {
        
        //ShowProgressViewCont is initialized with the nibName
        showProgressViewController = [[ShowProgressViewCont alloc]initWithNibName:@"ShowProgressViewCont" bundle:nil];
        
        //UINavigationController is initialized with the rootViewController showProgressViewController
        navigationController = [[UINavigationController alloc]initWithRootViewController:showProgressViewController]; 
        
        //The transition style of the navigationController is set to UIModalTransitionStyleCrossDissolve
        navigationController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
        
        //Presents a modal view managed by the given view controller to the user.Here navigation Controller that manages the modal view.
        [self presentModalViewController:navigationController animated:YES];
    
    }
	@catch(NSException * e){NSLog(@"Exception At: %s %d %s %s %@",__FILE__,__LINE__,__PRETTY_FUNCTION__,__FUNCTION__,e);}@finally{}
}

then after click download it takes 5 to 6 sec for appear the next screen that is

![when we click download button in initial screen it will appears this screen][2]

here it consists initially having download images 

my actual question is can we reduce the reaction time when we click on download button in initial screen with in 2 or 3seconds i want the second screen
