I would like to add a UIButton in the top of keyboard in my app view. Any idea on how to do this?
You need to set the inputAccessoryView
property on your text field.
This can be any view - so, for example, a toolbar with a done button. Example:
UIToolbar * myToolbar = [[[UIToolbar alloc] initWithFrame.... etc
// Add button to toolbar here
myTextField.inputAccessoryView = myToolbar;
