    <p>I've recently picked up app writing as a hobby and I've run into a problem with my first app. My first app attempt is fairly simple...a domino game. I started out using an NSObject class to describe each tile, but I think I've decided that CCSprite is easier for me at the moment.</p> <p>The first step was creating an NSArray of all the tiles and then shuffling them. This is where I'm getting stuck....</p> <p><strong>Domino.h</strong> </p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import "cocos2d.h" @interface Domino : CCSprite { int int_leading; int int_trailing; int int_suitrank; int int_trickvalue; NSString *str_tilename; NSString *str_mirrortilename; } @property int int_leading,int_trailing, int_suitrank, int_trickvalue; @property(nonatomic, retain) NSString *str_tilename; @property(nonatomic, retain) NSString *str_mirrortilename; -(void) print; -(void) setTileName: (NSString *) theTileName; -(void) setMirrorName: (NSString *) theMirrorName; -(NSString *) str_tilename; -(NSString *) str_mirrortilename; @end </code></pre> <p><strong>Domino.m</strong> </p> <pre><code>@implementation Domino @synthesize int_leading,int_trailing, int_suitrank, int_trickvalue, str_tilename, str_mirrortilename; //@synthesize char_tilename, char_mirrortilename; -(void) print { NSLog (@"%i/%i", int_leading, int_trailing);} -(void) setTileName: (NSString *) theTileName; { str_tilename=[[NSString alloc] initWithString: theTileName]; } -(void) setMirrorName: (NSString *) theMirrorName; { str_mirrortilename=[[NSString alloc] initWithString: theMirrorName]; } -(NSString *) str_tilename { return str_tilename; } -(NSString *) str_mirrortilename { return str_mirrortilename; } @end </code></pre> <p><strong>helloworld.m</strong></p> <pre><code>// Import the interfaces #import "HelloWorldLayer.h" #import "Domino.h" // HelloWorldLayer implementation @implementation HelloWorldLayer +(CCScene *) scene { // 'scene' is an autorelease object.

    1. COTry commenting out this line sprite=[CCSprite spriteWithSpriteFrameName:name];. Does your program still crash?

    2. COYes, that was a part of the problem. The biggest issue was that I was trying to pass the domino ccsprite subclass properties into a ccsprite class. Commenting that line out was what made me realize what I was doing wrong.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
