How to switch views from barbuttonitem? - ios

Question

I have an overlay in which I've created a toolbar containing a done button.
The name of the selector for done button is doneButtonPressed.
Now when I click done button, how do I get a new nib view? Let's us assume I created a nib named TestViewController.
-(void)doneButtonPressed {
//What goes here?
}

If you want to instantiate a UIViewController from a nib you can use the following line of code:
UIViewController *viewControllerName = [[UIViewController alloc] initWithNibName:(NSString *) bundle:(NSBundle *)];
Then you can present the view modally with:
[self presentModalViewController:(UIViewController *) animated:(BOOL)];
Now if you are using a storyboard, then you could just instantiate a view controller from a storyboard object.
Not sure if this is what you are looking for, but you could turn your view into a "container view". To do that you will need to create subviews and then just switch them out. I did this when I wanted a menu to control a different view.
[self.view insertSubview:(view you want to insert) atIndex:0];
Then when you want to switch it out:
[[[self.view subviews] objectAtIndex:0] removeFromSuperview];
[self.view insertSubview:(view you want to replace with) atIndex:0];
EDITED
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(doneButtonPressed:)];
- (void)doneButtonPressed {
SkipQViewController *skipQ = [[SkipQViewController alloc] initWithNibName:#"Name" bundle:bundleName];
[self presentModalViewController:skipQ animated:YES];
}
If that does not work try using: SkipQViewController *skipQ = [[SkipQViewController alloc] init]; to instantiate your view controller.
-EDIT-
Instantiate the view controller as such: SkipQViewController *skipQ = (SkipQViewController *)[[UIViewController alloc] initWithNibName:#"sqvc" bundle:nil];
