Question

I want to launch a method every time when user just highlights a cell (doesn’t select it) in UITableView. Could you tell me please, how is it possible to do this ?

I want to do it because I have a custom cell with a pictures on it and I want to change pictures every time when user highlights the cell.

UPD: By highlight I mean that user just highlights a cell and don’t release the finger from it. By select I mean when didSelectRowAtIndexPath is being launched (so the user releases the finger from the cell after he presses on it)

Answer 1

How do you envisage the user would ‘highlight’ a cell rather than ‘selecting’ one?

In iOS (or any touch based environment really) there is no concept of just highlighting a cell rather than selecting one. The only callback you get when the user touches a cell is didSelectRowAtIndexPath:

It might be worth reading up on the documentation on tables here.

UPDATE:

Ah OK, in that case you want to set the highlightedImage property of the cells imageView a bit like this;

cell.imageView.image = [UIImage imageNamed:@"normal_image.png"];
cell.imageView.highlightedImage = [UIImage imageNamed:@"highlighted_image.png"];
