CCTextFieldTTF Keyboard Type Change


I am using CCTextFieldTTF in my app.
For a few of my textfields, I only really need numeric inputs.
Is there a way to specify the keyboard type to be numeric pad only with those CCTextFieldTTFs???

Also, when I tap on a CCTextFieldTTF, the keyboard pops up. After input, one has to click on “return” to hide the keyboard.
Is there a way to allow the user to tap on a different CCTextFieldTTF to hide the current keyboard and popup another keyboard for that CCTextFieldTTF?
Or even just to hide the keyboard by tapping on the screen again when the keyboard is showing?

Thank you….
