How to include return button in UIKeyboardTypeDecimalPad?

Question

I am implemented a UITextField which is supposed to only let user include decimal numbers. I have changed the keyboard type to UIKeyboardTypeDecimalPad but there is no return button on this keyboard layout to get out of the text field. I don't want to add extra controls on the keyboard as it looks messy. How can I change the dot button to return and change its functionality or is there another alternative?

Answer 1

By default return key doesn't comes with Decimal keyboard type. Use the following code snippet to acheive that:

UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 35.0f)];
    toolbar.barStyle=UIBarStyleBlackOpaque;

    // Create a flexible space to align buttons to the right
    UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

    // Create a cancel button to dismiss the keyboard
    UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(resetView)];

    // Add buttons to the toolbar
    [toolbar setItems:[NSArray arrayWithObjects:flexibleSpace, barButtonItem, nil]];

    // Set the toolbar as accessory view of an UITextField object
    _yourTextField.inputAccessoryView = toolbar;

Hope this helps. Happy coding !!
