    <p>Is there any way to get a location of a menu button in Cocos2d when I've clicked it?</p> <p>So I have a menu:</p> <p>HelloWorld.h</p> <pre><code>//creating a menu CCMenu *menu; </code></pre> <p>HelloWorld.m</p> <pre><code>// initializing the menu and its position menu = [CCMenu menuWithItems:nil]; menu.position = ccp(0,0); // set cells in placing grid [self setItem]; [self addChild:menu]; - (void)setItem { //this method is a loop that creates menu items //but i've simplified it for this example, but please keep in mind that there are lots //of menu items and tagging them could be troublesome for (int i = 1; i &lt;= 13; i++) { for (int j = 1; j &lt;= 8; j++) { // this creates a menu item called grid CCMenuItem grid = [CCMenuItemSprite itemWithNormalSprite:[CCSprite spriteWithSpriteFrameName:@"menuItem.png"] selectedSprite:[CCSprite spriteWithSpriteFrameName:@"selected.png"] target:self // when button is pressed go to someSelector function selector:@selector(someSelector:)]; //coordinates float x = (j+0.55) * grid.contentSize.width; float y = (i-0.5) * grid.contentSize.height; //passing the coordinates grid.position = ccp(x, y); //add grid to the menu [menu addChild:grid]; //loop unless finished } } } -(void)someSelector:(id)selector { //i know when the button is pressed but is there any way //to pass selected menu coordinates to this function? NSLog(@"Grid is pressed"); } </code></pre> <p>Basically what happens above is - I create a menu, then I call a function that creates menu items, once those menu items are created they are added to the menu. Each menu items has a target of self and selector is someSelector function, which I want to pass parameters to(menu button location).</p> <p>What I want to do here is,</p> <p>When I run the program in simulator I want to be able to get a location of a menu button pressed.</p> <p>Thanks, looking forward to hearing from you.</p> <p>I think I found a solution to my own question:</p> <pre><code>-(void)someSelector:(id)selector </code></pre> <p>has to be changed into</p> <pre><code>-(void)someSelector:(CCMenuItem *) item </code></pre> <p>and then you can do this:</p> <pre><code>NSLog(@"Grid is pressed %f %f", item.position.x, item.position.y); </code></pre> <p>and voila! :)</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.
