    <p>I'm currently reading "Learn iPhone and iPad Cocos2D Game Development". i am not able to use a loading scene. i have HelloWorldScene.m, when i click it, it should show ScoreScene.m with a LoadingScene in between. and when i click it again, should go back. but it wont happen. the update method won't be executed(i added a CCLOG() there) here is my code: </p> <p>LoadingScene.m: </p> <pre><code>#import "LoadingScene.h" #import "ScoreScene.h" #import "HelloWorldScene.h" @implementation LoadingScene +(id) sceneWithTargetScene: (TargetScenes) targetScene { return [[[self alloc] initWithTargetScene: targetScene] autorelease]; } -(id) initWithTargetScene: (TargetScenes) targetScene { if ((self = [super init])) { targetScene_ = targetScene; CCLabelTTF *label = [CCLabelTTF labelWithString:@"Loading..." fontName:@"Marker Felt" fontSize:64]; [self addChild:label]; CCLOG(@"this is inside initwithtargetscene"); [self scheduleUpdate]; } return self; } -(void) update: (ccTime) delta { CCLOG(@"this is inside update"); [self unscheduleAllSelectors]; switch (targetScene_) { case TargetSceneScoreScene: [[CCDirector sharedDirector] replaceScene:[ScoreScene scene]]; break; case TargetSceneHelloWorld: [[CCDirector sharedDirector] replaceScene:[HelloWorld scene]]; break; default: break; } } @end </code></pre> <p>ScoreScene.m:</p> <pre><code>#import "ScoreScene.h" #import "LoadingScene.h" @implementation ScoreScene +(id) scene { // 'scene' is an autorelease object.

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).
