Question

Let’s say I have this code:

if ([resultButton.titleLabel.text isEqualToString:@"Tax"]) {

        TAXViewController *controller = [[TAXViewController alloc]initWithNibName:@"TAXViewController" bundle:nil];
        controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
        [self presentViewController:controller animated:YES completion:nil];
        [controller release];

    }else if ([resultButton.titleLabel.text isEqualToString:@""]){

        RENTViewController *controller = [[RENTViewController alloc]initWithNibName:@"RENTViewController" bundle:nil];
        controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
        [self presentViewController:controller animated:YES completion:nil];
        [controller release];

    }else if //repeats a lot......

And I want to use this same exact code in multiple .h files. Is there a way to write the code (in only one place) and access it from other .h files without having it repeat everywhere?

So in the end I guess, I could just pass a string to that other .h/.m files and it would open the view with the matching string.

Answer 1

Put it in one class and make all of the other files you want to access it in a subclass of it.

@interface SomeController : BaseViewController

You can also WAY simplify your code

UIViewController *controller;
if ([resultButton.titleLabel.text isEqualToString:@"Tax"])
        controller = [[TAXViewController alloc]initWithNibName:@"TAXViewController" bundle:nil];
else if ([resultButton.titleLabel.text isEqualToString:@""])    
        controller = [[RENTViewController alloc]initWithNibName:@"RENTViewController" bundle:nil];
else if
....
//after all if-else statements
controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:controller animated:YES completion:nil];
[controller release];
