Question

I am trying to make a Tab Bar application where one of the ViewController contains a UIToolbar with a UISegmentedController. The problem I have run into is setting up the UISegmentedController to switch between two views, for the views I am trying to switch between are subclasses of UIWebView and I would like to have them in separate files. (e.g. not just setting up the two views in “-viewDidLoad” of the ViewController.

The code of the method in the ViewController looks like:

- (IBAction)segmentedControlChanged
{   
switch (segmentedControl.selectedSegmentIndex)
    {case 0:
        [self.view addSubview:videosView];
        [imagesView removeFromSuperview];
        NSLog(@"1");
        break;
case 1:
        [self.view addSubview:imagesView];
        [videosView removeFromSuperview];
        NSLog(@"2");
        break;
default:
        break;
}

Where I have the videosView.h, videosView.m, imagesView.h, and imagesView.m imported in at the top of this document and set up as subclasses of UIWebView.

The errors I am getting seem to indicate that its not accepting imagesView or VideosView in the addSubview and also that removeFromSuperview is not a known class method.

Thanks in advance!

1- A UIViewController does not respond to removeFromSuperview, a UIView does

2- addSubview required a subclass of UIView to be passed to it, not a UIViewController

- (IBAction)segmentedControlChanged
{   
switch (segmentedControl.selectedSegmentIndex)
    {case 0:
        [self.view addSubview:videosView.view];
        [imagesView.view removeFromSuperview];
        NSLog(@"1");
        break;
case 1:
        [self.view addSubview:imagesView.view];
        [videosView.view removeFromSuperview];
        NSLog(@"2");
        break;
default:
        break;
}
