My iphone app has several text fields. The "Did End on Exit" event on each text field calls a single action. How can I tell which text field called the action? Can I detect this from the sender object which is passed to the action?

A:
Sure, just set a tag (NSInteger) on each of the text fields, and then check against them on the sender object.
Look for more details under the documentation for UIView's tag property.

The sender object will be the UITextField in question. If you have a bunch of IBOutlets connecting to your text fields, you can simply compare if sender == aField to see which field it is.

note this is assuming you define your action methods like so:- (IBAction) myAction:(id)senderYou can then compare "sender" to whatever IBOutlet UITextField *variable you've defined to attach the text field to in IB.
