Touch listener in Corona SDK

We can assign touch listener to an object in corona as follows:


-- Create the object --
local rect = display.newRect(100,100,50,50)
rect:setFillColor(255,0,0)

-- Create the touch function --
local function myTouchFunction(event)
    if(e.phase=="began")then
         print("Touch begins...")
    elseif(e.phase=="moved")then
         print("Touch moved...")
    elseif(e.phase=="ended")then
         print("Touch ended...")
    end
end

-- Create the listener to the object --
rect:addEventListener("touch",myTouchFunction)

How to create UITextField programmatically: cocos2d/Xcode

In .h file:

        @interface SceneName : CCLayer <UITextFieldDelegate>
       
            UITextField *nameField;

In .m file:

   // To create UITextField and assigning properties//

        -(void)createTextField{
           // create a UIView here(say profileView). Then do the following code //

            nameField = [[UITextField alloc] initWithFrame:CGRectMake(5, 20, 150, 30)];
            nameField.center = CGPointMake(285, 120);
            nameField.backgroundColor = [UIColor whiteColor];
            nameField.textAlignment = UITextAlignmentCenter;
            nameField.delegate = self;
            [nameField.layer setBorderColor:[[UIColor redColor]CGColor]];
            [nameField.layer setBorderWidth:1];
            nameField.layer.cornerRadius = 8;
            nameField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
            [nameField addTarget:self action:@selector(valueChanged)
                                   forControlEvents:UIControlEventEditingChanged];
            [profileView addSubview:nameField];
        }

  
   // To resign first responder/keyboard //
   
        -(BOOL)textFieldShouldReturn:(UITextField *)textField
            {
                [textField resignFirstResponder];
                NSLog(@"%@ ",textField.text);                       // To get/print the data from the TextField
                return YES;
            }

        -(void)valueChanged{
            // To Limit text field text length //
            if ([nameField.text length] > 12) {
                nameField.text = [nameField.text substringToIndex:12];
            }
        }

    /*---------Some other important UITextField delegates---------*/
    -(BOOL) textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
        return YES;
    }

    - (BOOL) textFieldShouldBeginEditing:(UITextField *)textField{
        return YES;
    }

    - (void) textFieldDidBeginEditing:(UITextField *)textField
    {
   
    }
