Answer 1

UITextField store data as NSString in text property:

@property(nonatomic, copy) NSString *text;

e.g:

NSLog(@"my text: %@", muTextField.text);

if you want to handle text changes while user edits text use delegate method:

 -(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
