    <p>So I created an <code>NSMutableArray</code> of <code>UIImageView</code> like this:</p> <pre><code>NSMutableArray* imageViewArray = [[NSMutableArray alloc] init]; for(int i = 0; i &lt; 15; i++){ UIImageView* imageView = [self animationInit:imageArray xPos:0 yPos:480 wFrame:32 hFrame:32 duration:0.5 repeat:0]; [imageViewArray addObject:imageView]; [imageView release]; imageView = nil; [self.view addSubview:[imageViewArray objectAtIndex:i]]; } </code></pre> <p>The method "animationInit" is a method I created to init the UIImageView. Its implementation is this:</p> <pre><code>-(UIImageView*)animationInit:(NSArray*)imageArray xPos:(float)x yPos:(float)y wFrame: (float)w hFrame:(float)h duration:(float)duration repeat:(float)count { UIImageView* imageAnimation = [[UIImageView alloc] initWithFrame:CGRectMake(x, y, w, h)]; imageAnimation.animationImages = imageArray; imageAnimation.animationDuration = duration; imageAnimation.animationRepeatCount = count; return imageAnimation; } </code></pre> <p>I am able to set the center of each UIImageView in the array using like this:</p> <pre><code>[imageViewArray objectAtIndex:Index] setCenter:CGPointMake(x, y)]; </code></pre> <p>Now I would like to do be able to modify the <code>x</code> and <code>y</code> points like I would with a normal <code>UIImageView</code>. An example: <code>UIImageView.center = CGPointMake(UIImageView.center.x + 5, UIImageView.center.y + 5);</code></p> <p>The problem here is I have no idea how to access the "UIImageView.center.x/y" within the array of <code>UIImageViews</code>. Is there any way to access the "center.x/y" like I was able to with "setCenter:" or would I be better off creating a bunch of <code>CGPoints</code> to hold the <code>x</code> and <code>y</code> of the <code>UIImageViews</code> in the array?</p> <p>When I try <code>[imageViewArray objectAtInded:Index].center.x</code>, I get the following error.</p> <blockquote> <p>Request for member 'center' in something no a structure or union</p> </blockquote> <p>Is there a solution or workaround?</p>

    1. COYou can loop through the image views in the array and change their center property. What's the problem you have with that?

    2. COsorry i guess im not so good at explaining things what i want to do is something like this: [[imageViewArray objectAtIndex:Index] setCenter:CGPointMake([imageViewArray objectAtIndex:Index].x + 5, [imageViewArray objectAtIndex:Index].y + 5])]; but obviously this is not possible the way i have written it. does this make more sense now?

    3. COYou can do it like that? Why do you say that it is not possible?

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.
