IPhone tracking memory overwrites

I have an issue where i call a function on an object in one of my classes but at the time I call its holding a reference to a differ开发者_如何转开发ent object type and its a different type everytime, so i receive messages as so -[UIGestureRecognizerTarget stopConnection]: unrecognized selector sent to instance 0x6b23710 and the types are always UI type classes.

So this leads me to believe something is overriding memory somewhere and I can't track it down! It only happens when i delete a row from a UITableView, and thought that maybe this is deleting something before im ready for it too but nothing seems to have dealloced before im calling this function!

Is there anyway I can track when a value at memory address changes, or what would be the best way to track down what is changing the reference of my object in XCode??

This is a memory management issue. An object is being dealloced and another is being put in its place while you're still holding a reference to the old one. You can run the app with Zombies and see what object it is, but it's probably whatever object was being shown in your table view.
