    <p>I have a Background view (UIImageView) in that i am adding a view(UIView). this contentView(UIView) contains UIPanGestureRecognizer.</p> <p>I am giving UIPanGestureRecognizer to contentView by bellow code :</p> <pre><code>UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(movePhoto:)]; [panRecognizer setMinimumNumberOfTouches:1]; [panRecognizer setDelegate:self]; [contentView addGestureRecognizer:panRecognizer]; [panRecognizer release]; </code></pre> <p>and then i am adding this contentView to Background View (UIImageView) by bellow code : </p> <pre><code>[imgBG addSubview:contentView]; // here imgBG is Background view. </code></pre> <p>but when i move this contentView it goes out of imgBG.</p> <p>bellow is the method to move contentView</p> <pre><code> [[[(UITapGestureRecognizer*)sender view] layer] removeAllAnimations]; [self.view bringSubviewToFront:[(UIPanGestureRecognizer*)sender view]]; CGPoint translatedPoint = [(UIPanGestureRecognizer*)sender translationInView:self.view]; if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateBegan) { firstX = [[sender view] center].x; firstY = [[sender view] center].y; } translatedPoint = CGPointMake(firstX+translatedPoint.x, firstY+translatedPoint.y); [[sender view] setCenter:translatedPoint]; CGFloat finalX = [sender view].center.x; CGFloat finalY = [sender view].center.y; [[sender view] setCenter:CGPointMake(finalX, finalY)]; </code></pre> <p>I think, here the contentView should remain inside the imgBG as it is the subview of imgBG.</p> <p>Please let me know whether there is a problem in my code or its due to UIPanGestureRecognizer.</p> <p>thanks in advance.</p>

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.
