    text
    copied!<p>I'm looking for a way to uniquely identify instances of UITableViewCells even after they have been recycled (dequeued) via <a href="http://docs.go-mono.com/index.aspx?link=M%3aMonoTouch.UIKit.UITableView.DequeueReusableCell%28System.String%29" rel="nofollow">DequeueReusableCell(string identifier)</a> - without subclassing or using a container object.</p> <p>So basically, when I create a new cell, I want to use a unique id of this cell as a key to store another related object in a dictionary. Later on, when the cell get's recycled/dequeued, I want to read the related objected from the dictionary. <em>I am totally aware that the recycled cell may be placed at any index path in the table and may (most likely) contain other data than before - the other object really is related to the cell instance, not the index path.</em></p> <p>Loosing relation to the object must be avoided. The obtained id must at all cost be the same that was used when the cell was created.</p> <p>This was previously achieved by generating a random number and storing it as the cell's tag. However, those tags could collide (when the same random number is generated twice) and I would only want to implement collision avoidance as a last resort. So I'm looking for a better way.</p> <p>I've looked at <a href="http://docs.go-mono.com/monodoc.ashx?link=P%3aMonoTouch.Foundation.NSObject.ClassHandle" rel="nofollow">ClassHandle</a>, <a href="http://docs.go-mono.com/monodoc.ashx?link=P%3aMonoTouch.Foundation.NSObject.Handle" rel="nofollow">Handle</a> and <a href="http://docs.go-mono.com/monodoc.ashx?link=P%3aMonoTouch.Foundation.NSObject.SuperHandle" rel="nofollow">SuperHandle</a> properties. The only one staying consistent among dequeues seems to be the ClassHandle.</p> <p>Is it safe to use the ClassHandle property for this purpose? If not, what other options are there?</p>
