<p>Formally I had accepted termes's answer first and that worked too, but I have found a more simpler solution to this process. There is no need for two gesture recognizers, it is achievable with a simple tap gesture recognizer with number of touches count to two. Here is the code:</p> <pre><code>UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)]; tapRecognizer.numberOfTapsRequired = 1; tapRecognizer.numberOfTouchesRequired = 2; tapRecognizer.delegate = self; [self addGestureRecognizer:tapRecognizer]; </code></pre> <p>Now, in the handle tap method we can easily get the two touch points by "<a href="http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIGestureRecognizer_Class/Reference/Reference.html#//apple_ref/occ/instm/UIGestureRecognizer/locationOfTouch%3ainView%3a" rel="nofollow">locationOfTouch:inView:</a>", a instance method of UIGestureRecognizer class. So in the <code>handleTap:</code> method we need to check if the two touch points are in the desired location. Here is the code:</p> <pre><code>-(void)handleTap:(UITapGestureRecognizer*)recognizer { if (recognizer.state == UIGestureRecognizerStateEnded) { CGPoint point1 = [recognizer locationOfTouch:0 self]; CGPoint point2 = [recognizer locationOfTouch:1 self]; if ([self validateTapIn:point1 and:point2]) { resultLabel.text = @"success"; } } } -(BOOL)validateTapIn:(CGPoint)point1 and:(CGPoint)point2 { return (CGRectContainsPoint(label1.frame, point1) && CGRectContainsPoint(label2.frame,:point2)) || (CGRectContainsPoint(label1.frame, point2) && CGRectContainsPoint(label2.frame, point1)); } </code></pre>

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.
