Identify UIImageView and UITextView created in loop iOS - ios

Question

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:
for (int i=0; i<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)];
}
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.
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?
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.
My target is for example:
When i click on imageView1 in the first row should change image in imageView3 of the same row.
When i click on imageView3 in the fourth row should change text in textView2 of the same row.
And so on..
Is there any alternative method without using the tag attribute?
I hope I explained myself

Answer 1

You can use the tag property, but without using the same tag more then once. Some little math should do the trick to identify views in the same row by their tags...
BUT:
I wouldn't recommend using tags. Make yourself a custom view class, e.g. MyRow, containing the 6 views belonging together as subviews. From there you can go anywhere.
Got a problem, invent an object. Always works.
BIGGER BUT: I'd strongly recommend to go with UICollectionView or UITableView.

UIView has a "tag" property, which you can use for anything you want. The default value is 0 and it doesn't do anything at all, except store the value.
Typically you would set the tag to be an array index.
So you could do:
textView1.tag = i;
textView2.tag = i;
imageView1.tag = i;
imageView2.tag = i;
imageView3.tag = i;
imageView4.tag = i;
Or perhaps something more clever, like:
textView1.tag = 1000000 + i;
textView2.tag = 2000000 + i;
imageView1.tag = 3000000 + i;
imageView2.tag = 4000000 + i;
imageView3.tag = 5000000 + i;
imageView4.tag = 6000000 + i;
Or maybe you could have an array property mapping them:
#property NSMutableArray tagMap;
textView1.tag = self.tagMap.count;
[self.tagMap addObject:#{#"var": #"textView1", #"index":[NSNumber numberWithInteger:i]}];
