Update UISteppers value from textfield - textfield

Question

here is the case.
I would like to type a value in a text field and pass it to the current uisteppers value.
if for example current value is 2 and i enter 35 in the textfield then when i press the + button on the stepper the value should go to 36 (or by pressing - to 34)
Thanks
--------------------------------------EDIT AFTER 1st REPLY----------------------------------
thanks for fast reply, since i am fresher to all this i declared
#interface GenericViewController : UIViewController <UITextFieldDelegate> {... in my header. and changed my code inside Generic Controller to:
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
[textField addTarget:self action:#selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
NSLog(#"######PASS DELEGATE ###############");
return YES;
}
- (void) textFieldDidChange:(id)sender {
UITextField *textField = (UITextField *)sender;
textField = changeNfpHand;
NSLog(#"##############################");
NSLog(#"textfield is now #------> : %f" , DateStepper.stepValue);
self.DateStepper.stepValue = [textField.text doubleValue];
// self.DateStepper.stepValue = [self.Nfp.text doubleValue];
NSLog(#"VALUE STEP is #------> : %f" , DateStepper.stepValue);
NSLog(#"self.Nfp.text #------> : %#" , self.Nfp.text);
Now I am new to all this.. i tried to call [self textFieldDidChange:self]; but no luck. it seems that i cant get it work...any ideas of what am i doing wrong ? Thanks in advance

Answer 1

In the delegate of UITextField, add the following code, which will make the UIStepper's step value be changing according to what you enter in UITextField.
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
[textField addTarget:self action:#selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
return YES;
}
- (void) textFieldDidChange:(id)sender {
UITextField *textField = (UITextField *)sender;
self.stepper.stepValue = [textField.text doubleValue];
}
