Question

Is it possible to implement a subview of a UITableViewCell on the left side of the cell that crossfades when the table enters the editing mode?
Another problem I face is that the bounds of the cell.textLabel are read-only. Is it possible to use some sort of inset for that label? (Because I, like mentioned above, want to use a View on the left side)

Edit: How do I perform an action (in this case fade a subview) when the whole table enters editingmode? (Not through a swipe over a cell). The reason why I want to implement this is because the tableview shows the “-” button on the left side of the cells if it is in editingmode. (I want to show my own button on the left side of the cells if editing=NO, fade it out if editing=YES and show it again if the tableView leaves editingmode (editing=NO))

A first thought directs me to something like this:

- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
    [super setEditing:editing animated:animated];
    if(editing) {
        //fade out my own button
    } else {
        //show my own button
    }
}

But I would have to loop through all the cells and I think this leads to a substantial performance worsening. What do you think?

Answer 1

In the end I created a custom UILabel that I used instead of the default UITableView textLabel and added a custom button on the left side. In the setEditing method I fade this button in/out.
