How do I reference my MainViewController from another class?
- by todd412
Hi, I am building an iPhone Utility app that uses UIImageView to display an animation. Within the MainViewController's viewDidLoad() method, I am creating an instance of a CustomClass, and then setting up the animations:
- (void)viewDidLoad
{
[super viewDidLoad];
cc = [CustomClass new];
NSArray * imageArray = [[NSArray alloc] initWithObjects:
[UIImage imageNamed:@"image-1-off.jpg"],
[UIImage imageNamed:@"image-2-off.jpg"],
[UIImage imageNamed:@"image-3-off.jpg"],
[UIImage imageNamed:@"image-4-off.jpg"],
nil];
offSequence = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
offSequence.animationImages = imageArray;
offSequence.animationDuration = .8;
offSequence.contentMode = UIViewContentModeBottomLeft;
[self.view addSubview:offSequence];
[offSequence startAnimating];
}
That works fine. However, I would like to be able to move all the above code that sets up the UIImageView into my CustomClass. The problem is in the second to last line:
[self.view addSubview:offSequence];
I basically need to replace 'self' with a reference to the MainControllerView, so I can call addSubview from within my CustomClass. I tried creating an instance var of CustomClass called mvc and a setter method that takes a reference to the MainViewController as an argument as such:
- (void) setMainViewController: (MainViewController *) the_mvc
{
mvc = the_mvc;
}
And then I called it within MainViewController like so:
[cc setMainController:MainViewController:self];
But this yields all sorts of errors which I can post here, but it strikes me that I may be overcomplicating this. Is there an easier way to reference the MainViewController that instanatiated my CustomClass?
