    <p>For various reasons, I've moved these methods from a UIView subclass to my viewcontroller. And I finally got it working, except for one thing. Not only am I able to drag the UIImageviews I've programmatically created, but the actual view controllers view is draggable too. Creating this much undesired effect. I guess it's the fact that it's touches anyobject, and the background itself is an object. I'm just not sure how exclude the background. I would think that it would need the "UserInteraction enabled", but I guess not? I only want it to make UIImageViews draggable. Please forgive my noobness. I'm still learning. </p> <p>I have all the imageviews i'd want "touchable" in an NSMutableDictionary called "letterDictionary". Would it be possible to only have touch apply to what's in the dictionary? </p> <p><a href="http://imgur.com/W08dI" rel="nofollow">http://imgur.com/W08dI</a></p> <pre><code>- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { UITouch *touch = [touches anyObject]; touchPoint = [touch locationInView:self.view]; movingLetter = [touch view]; CGPoint pointInside = [touch locationInView:[touch view]]; if ([movingLetter pointInside:pointInside withEvent:event]) touchedInside = YES; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { if (touchedInside) { UITouch *touch = [touches anyObject]; CGPoint newPoint = [touch locationInView:self.view]; // get the new touch location movingLetter.center = CGPointMake(movingLetter.center.x + newPoint.x - touchPoint.x, movingLetter.center.y + newPoint.y - touchPoint.y); touchPoint = newPoint; } } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { if (touchedInside) { UITouch *touch = [touches anyObject]; CGPoint newPoint = [touch locationInView:self.view]; movingLetter.center = CGPointMake(movingLetter.center.x + newPoint.x - touchPoint.x, movingLetter.center.y + newPoint.y - touchPoint.y); if (CGRectIntersectsRect([movingLetter frame], [placeHolder frame])) { movingLetter.center = placeHolder.center; } } touchedInside = NO; } - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { touchedInside = NO; } </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.
