问题
So I've seen previous questions similar to this but they were of no help. I've read Apple's documentation too but I could not understand where I've gone wrong. AFAIK I did everything logically, but when I click on my done button on an UItoolbar overlay, the button can be pushed but it does not do anything. This obviously means it fails to acknowledge the written code. But how?
I want to bring up the .nib of "TableViewController" when a done button is clicked on my UIToolBar. But the below isn't allowing the click to bring up a new view. How do I rectify this? Please show me where I went wrong and what should be replaced and why.
//Here's the selector:
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:
UIBarButtonSystemItemDone target:self action:@selector(doneButtonPressed)];
Here's how I made my action. Btw, the uitoolbar has no nib, it's an overlay on the imagepickercontroller(camera mode).
-(void)doneButtonPressed {
TableViewController *tableView = [[TableViewController alloc]
initWithNibName:@"TableViewController" bundle:nil];
tableView.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:tableView animated:YES];
}
//Yet nothing happens when I click on my done button on my overlay. The button can be
clicked nothing happens. Please shed any insight pleasee!

This may not actually be the problem, but if the code your using above is how you're dismissing your Modal view controller it is incorrect. Other than possible improper usage I don't see any problems.
Use what you're using to present the Modal view controller, then to dismiss it use this:
[self dismissModalViewControllerAnimated:YES];
