IOS monitors changes in textField values in real time

IOS monitors changes in textField values in real time
Considering the proxy method:

TextFieldDidEndEditing cannot listen for real-time changes in textFiled. To implement real-time monitoring, we recommend that you register a notification to listen for real-time changes in textField. directly add the Code:

 

 

 

 

[[Nsnotifcencenterdefacenter] addObserver: selfselector: @ selector (infoAction) name: UITextFieldTextDidChangeNotificationobject: nil];

 

 

-(Void) infoAction

{

NSIndexPath * index = [NSIndexPathindexPathForRow: 0 inSection: 1];

OrderConfirmInfoTableViewCell * cell = (OrderConfirmInfoTableViewCell *) [_ tableViewcellForRowAtIndexPath: index];

_ PhoneStr = cell. phoneField. text;

_ AddrStr = cell. addressField. text;

}

In infoAction, you can assign a value to another object in real time to change the value of the textfield of the listener.
