    <p>*<strong><em>Working Code Now</em>*</strong></p> <p>OK, I thought that this would be easy to get working but it turns out to not work like I expected.</p> <p>I am trying to get the Touch location from a CCLayer that can be moved or zoomed, not the location on the screen itself? here is how I thought that it would work but it crashes?</p> <p>Interface #import "cocos2d.h"</p> <pre><code>@interface TestTouch : CCLayer { CCLayerColor *layer; } +(CCScene *) scene; @end </code></pre> <p>Implementation</p> <pre><code>#import "TestTouch.h" @implementation TestTouch +(CCScene *) scene { // 'scene' is an autorelease object. CCScene *scene = [CCScene node]; // 'layer' is an autorelease object. TestTouch *layer = [TestTouch node]; // add layer as a child to scene [scene addChild: layer]; // return the scene return scene; } - (id)init { self = [super init]; if (self) { CGSize winsize = [[CCDirector sharedDirector]winSize]; CCLayerColor *layer = [CCLayerColor layerWithColor:ccc4(255, 255, 255, 255)]; // layer.scale = 0.7f; layer.contentSize = CGSizeMake(640, 960); layer.position = CGPointMake(winsize.width/2, winsize.height/2); layer.isRelativeAnchorPoint = YES; [self addChild:layer z:0]; [[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:layer priority:0 swallowsTouches:YES]; } return self; } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchStart = [[CCDirector sharedDirector] convertToGL:[touch locationInView:[touch view]]]; touchStart = [layer convertToNodeSpace:touchStart]; NSLog(@"Touch:%f,%f",touchStart.x, touchStart.y); return YES; } @end </code></pre> <p>If I change this line to include "self":</p> <blockquote> <p>[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];</p> </blockquote> <p>It will obviously work but then I get the location relevant to the screen and not the layer, which is what I need.</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.
