    <p><code>self.superview.title = @"i";</code> evaluates to an object of type <code>UIView</code>, and <code>UIView</code> has no <code>title</code> property. <code>UIViewController</code>s have a <code>parentViewController</code> property but <code>UIView</code>s don't.</p> <p>So the fundamental problem is that you're not properly separating your controller and your view classes. What you'd normally do is make the view you want to catch taps on a subclass of <code>UIControl</code> (which things like <code>UIButton</code> already are, but if it's a custom <code>UIView</code> subclass then you can just change it into a <code>UIControl</code> subclass since <code>UIControl</code> is itself a subclass of <code>UIView</code>), then in your controller add something like:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; // we'll want to know if the view we care about is tapped; // we've probably set up an IBOutlet to it but any way of // getting to it is fine [interestingView addTarget:self action:@selector(viewTapped:) forControlEvents:UIControlEventTouchDown]; // UIButtons use UIControlEventTouchUpInside rather than // touch down if wired up in the interface builder. Pick // one based on the sort of interaction you want } // so now this is exactly like an IBAction - (void)viewTapped:(id)sender { self.title = @"My new title"; } </code></pre> <p>So you explicitly don't invest the view with any knowledge about its position within the view hierarchy or how your view controllers intend to act. You just tell it to give you a shout out if it receives a user interaction.</p>

    1. COThanks Tommy, thats working perfectly now. As you advised, I moved all the onclick control into the controller and the view now just handles drawing.

    2. COUIResponder is not a subclass of UIView. It's the other way around.

    3. CO@SaurabhG Indeed, I've clearly typed `UIResponder` where I mean `UIControl`; I'll correct.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
