    <p>This is a step by step guide on how to implement gesture recognizers in your class:</p> <ol> <li><p>Conform your class to <code>UIGestureRecognizerDelegate</code> protocol.</p></li> <li><p>Instantiate the gesture recognizer. For example, to instantiate a <code>UITapGestureRecognizer</code>, we will do:</p> <pre><code>UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapFrom:)]; </code></pre> <p>Here, action is the selector which will handle the gesture. Here, our selector handleTapFrom will look something like:</p> <pre><code>- (void) handleTapFrom: (UITapGestureRecognizer *)recognizer { //Code to handle the gesture } </code></pre> <p>The argument to the selector is the gesture recognizer. We can use this gesture recognizer to access its properties, for example, we can find the state of the gesture recognizer, like, <code>UIGestureRecognizerStateBegan</code>, <code>UIGestureRecognizerStateEnded</code>, etc.</p></li> <li><p>Set the desired properties on the instantiated gesture recognizer. For example, for a <code>UITapGestureRecognizer</code>, we can set the properties <code>numberOfTapsRequired</code>, and <code>numberOfTouchesRequired</code>.</p></li> <li><p>Add the gesture recognizer to the view you want to detect gestures for. In our sample code (I will be sharing that code for your reference), we will add gesture recognizers to an imageView with the following line of code:</p> <pre><code>[self.imageView addGestureRecognizer:tapGestureRecognizer]; </code></pre></li> <li><p>After adding the gesture recognizer to the view, set the delegate for the gesture recognizer, i.e. the class which will handle all the gesture recognizer stuff. In our sample code, it would be like:</p> <pre><code>tapGestureRecognizer.delegate = self; </code></pre> <p><strong>Note:</strong> Assign the delegate after adding the gesture recognizer to the view. Otherwise, the action method won’t be called.</p></li> </ol>

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.
