    <p>I have created an array which stores either red, yellow, or green (3, 2, or 1) based on what the user hits. I want the code to choose a random number in the array and display the corresponding color on the screen. However, when the code runs, the program always chooses the last entered color and only shows that color. Code:</p> <pre><code>-(void)CreateEnemy:(ccTime)dt{ CCSprite *Enemy; int a; if (colorArray != nil) { a = arc4random()% [colorArray count]; } int y = [[colorArray objectAtIndex:a] integerValue]; if (y == 1) { Enemy = [CCSprite spriteWithFile:@"GreenBall.png"]; int x = arc4random()%320; Enemy.position = ccp(x, 530); id action = [CCMoveTo actionWithDuration:3 position:ccp(x, -30)]; [Enemy runAction:[CCSequence actions:action, [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)], nil]]; [enemyArray addObject:Enemy]; [self addChild:Enemy z:2 tag:1]; NSLog(@"Green Enemy Attack!!"); } else if (y == 2) { Enemy = [CCSprite spriteWithFile:@"YellowBall.png"]; int x = arc4random()%320; Enemy.position = ccp(x, 530); id action = [CCMoveTo actionWithDuration:3 position:ccp(x, -30)]; [Enemy runAction:[CCSequence actions:action, [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)], nil]]; [enemyArray addObject:Enemy]; [self addChild:Enemy z:2 tag:1]; NSLog(@"Yellow Enemy Attack!!"); } else if (y == 3) { Enemy = [CCSprite spriteWithFile:@"RedBall.png"]; int x = arc4random()%320; Enemy.position = ccp(x, 530); id action = [CCMoveTo actionWithDuration:3 position:ccp(x, -30)]; [Enemy runAction:[CCSequence actions:action, [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)], nil]]; [enemyArray addObject:Enemy]; [self addChild:Enemy z:2 tag:1]; NSLog(@"Red Enemy Attack!!"); } } </code></pre> <p>Y should be a randomly chosen color, but it never is.</p>

    3. COwell, the question is: are you sure that `[colorArray count]` has the value you expect it to have? could you put an NSLog trace there?

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.
