    <p>LayerB should use the <code>GL_SCISSOR_TEST</code> to trim the outside of itself. You can easily google for more information about it, it basically defines a <code>rect</code> and then uses <code>glScissor</code>on it to remove the outside. I have a class I extend when I need to do this, that goes as follows:</p> <pre><code>// // CCNodeClip.h // // Created by Ignacio Orlandoni on 7/29/11. // #import &lt;Foundation/Foundation.h&gt; #import "cocos2d.h" @interface CCNodeClip : CCLayer { } -(void)preVisit; -(void)postVisit; @end </code></pre> <p>-</p> <pre><code>// // CCNodeClip.m // // Created by Ignacio Orlandoni on 7/29/11. // #import "CCNodeClip.h" @implementation CCNodeClip -(void)visit { [self preVisit]; [super visit]; [self postVisit]; } -(void)preVisit { if (!self.visible) return; glEnable(GL_SCISSOR_TEST); CGPoint position = [self position]; //I don't remember if this rect really serves for both orientations, so you may need to change the order of the values here. CGRect scissorRect = CGRectMake(position.x, position.y, [self contentSize].width, [self contentSize].height); // CCLOG(@"Scrissor Rect: X: %02f, Y:%02f, W: %02f, H: %02f", scissorRect.origin.x, scissorRect.origin.y, scissorRect.size.width, scissorRect.size.height); // Handle Retina scissorRect = CC_RECT_POINTS_TO_PIXELS(scissorRect); glScissor((GLint) scissorRect.origin.x, (GLint) scissorRect.origin.y, (GLint) scissorRect.size.width, (GLint) scissorRect.size.height); } -(void)postVisit { glDisable(GL_SCISSOR_TEST); } @end </code></pre> <p>With that imported into <code>LayerB</code>, you can now define it as a <code>CCNodeClip</code> instead of <code>CCLayer</code>.</p> <p><strong>Some links...</strong></p> <p><a href="http://www.cocos2d-iphone.org/forum/topic/996" rel="nofollow noreferrer">glScissor &lt;&lt; cocos2d Forum</a></p> <p><a href="https://stackoverflow.com/questions/6914013/circle-shape-clipping-with-opengl-es-in-cocos2d">Circle shape clipping with opengl-es in cocos2d &lt;&lt; StackOverflow</a></p> <p><a href="https://stackoverflow.com/questions/3177751/cocos2d-iphone-sprite-cliping-mask-frame">Cocos2d iPhone - Sprite cliping/mask/frame &lt;&lt; StackOverflow</a></p> <p><a href="http://www.learn-cocos2d.com/tag/glscissor/" rel="nofollow noreferrer">Another Cocos2D gem: ClippingNode &lt;&lt; Learn-Cocos2d.com</a></p> <p><strong>As a side note...</strong></p> <p>CCScaleTo + CCMoveTo can be avoided if the anchor point for the sprite is centered, so the image stays centered in the container as it scales. (<code>.anchorPoint = ccp(0.5, 0.5);</code>)</p>

    1. COUsing your code seems to work perfectly! That was dead easy to implement. My app is landscape orientation only, and I didn't have to alter anything in your code. As far as the CCScaleTo and MoveTo goes, I'm actually zooming in on different points of the layer based on where the user touches, not just the center. Good point though. Thanks so much!

    2. COEven though the issue is resolved, I recommend you do look up `GlScissor` to try and fully understand how it works and what can it do. You are welcome.

    3. COYeah, as soon as I saw your post (about 3 minutes after you posted it) I did a google search and found many of the same links you posted. My problem was really a case of not knowing what to search for. I hadn't heard of GLScissor before. Your code seems more effecient than the setup on Learn-Cocos2d.com

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.
