    <p>I'm working in Xcode and i have a loop cycle in which i dynamically create UIImageViews and UITextviews and insert them in a UIScrollView. In every row, i create 4 UIImageViews and 2 UITextViews, so the code looks like this:</p> <pre><code>for (int i=0; i&lt;dim; i++){ UITextView *textView1= [[UITextView alloc] initWithFrame:CGRectMake(0, 0, screenWidth/2, 37)]; UITextView *textView2= [[UITextView alloc] initWithFrame:CGRectMake(screenWidth/2, 0, screenWidth/2, 37)]; UIImageView *imageView1 = [[UIImageView alloc] initWithFrame:CGRectMake(0,50,screenWidth/4,100)]; UIImageView *imageView2 = [[UIImageView alloc] initWithFrame:CGRectMake(screenWidth/4,50,screenWidth/4,100)]; UIImageView *imageView3 = [[UIImageView alloc] initWithFrame:CGRectMake(screenWidth/2,50,screenWidth/4,100)]; UIImageView *imageView4 = [[UIImageView alloc] initWithFrame:CGRectMake(screenWidth*3/4,50,screenWidth/4,100)]; } </code></pre> <p>The code to set images in UIImageViews, text in UITextViews and show them in the UIScrollView works great and i don't post it because it's too long.</p> <p>My problem is: when i click on an image, i call methods in which i want to make change to the ImageViews and TextViews of the same row, how can i identify them?</p> <p>Detecting the image clicked is not a problem using the recognizer.view, to detect other images of the same row i tried to set a tag to the views and then call "viewWithTag" to find them, but i have problems because the elements of the same row have the same tag value and i make confusion.</p> <p>My target is for example:</p> <ul> <li><p>When i click on imageView1 in the first row should change image in imageView3 of the same row.</p></li> <li><p>When i click on imageView3 in the fourth row should change text in textView2 of the same row.</p></li> <li><p>And so on..</p></li> </ul> <p>Is there any alternative method without using the tag attribute?</p> <p>I hope I explained myself</p>

    1. COIt sounds like you would be better off using a `UITableView` or a `UICollectionView` for what you want to do. As this would allow you to access the cells at a certain row/index and with a custom cell subclass you could access the image properties.

    2. CO@Evan inserting a UITextView into a UITableViewCell is asking for a world of pain if you want fine-grained control over the layout. I've done it, and there are definitely times when it should be avoided. It has to be taken on a case-by-case basis.

    3. CO@AbhiBeckert fair enough. Another option is to make a `UIView` subclass and expose everything as properties. You can avoid tags if you think through your structure.

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.
