I have a UITextField which inside a UITableCell in a xib file TableView dequeue the cell, try editing the text fieldon iOS 7, it work fine. When I tested the app in iOS 8, it crash the app and throw the exception below when touching (focus) on the textfield :
-[__NSCFString objectAtIndex:]: unrecognized selector sent to instance 0x7faacacbf110
The custom cell not override any UITableViewCell method and implement any method. The textfield just a UITextField, not override anything.
Problem found in all tableview which contain this cell. The textfield work fine when enable Secure Text Entry
