How to add a method to UITextField & UITextView?

Question

I want to put something like this in a method for UITextField & UITextView.

- (void)changeKeyboardType:(UIKeyboardType)keyboardType         


        

Answer 1

For each of these, you can create a category.

Interface file:

@interface UITextField (ChangeKeyboard)
- (void)changeKeyboardType:(UIKeyboardType)keyboardType;
@end

Implementation file:

@implementation UITextField (ChangeKeyboard)
- (void)changeKeyboardType:(UIKeyboardType)keyboardType {
    self.keyboardType = keyboardType;
    [self resignFirstResponder];
    [self becomeFirstResponder];
}
@end

That would be the way to add these, but I haven't tested the functionality.
