Add "Next TextField" key above standard keyboard of your TextFields

[cvp]

If you want a special key "Next TextField" above standard keyboard of all TextFields of a view
You have to design your own button (size, border, title, image, ...).
Add one call to your code and it is done

import ui
from objc_util import *

def NextFieldKeyInTextFieldKeyboard(view, button, background_color='lightgray'):
	# parameters: view = main view of textfields
	#							button = ui.Button designed by user (size, title, image...)
	#							background_color = background_color of InputAccessoryView
	# create ui.View for InputAccessoryView above keyboard
	v = ui.View()													# view above keyboard
	v.background_color = background_color	# background_color of user choice
	v.width = ui.get_screen_size()[0]			# width of screen, thus of keyboard
	v.height = button.height + 4					# only for Next button

	# code executed when Next key is tapped
	def Next_tapped(sender):
		s = sender.objc_instance.firstResponder()._nextKeyResponder().becomeFirstResponder()	
	button.action = Next_tapped						# code to be executed if button tapped
	v.add_subview(button)									# set as subview of view
	
	vo = ObjCInstance(v)									# get ObjectiveC object of v
	# attach to each textfield an InputAccessoryView abobe the keyboard
	for sv in view.subviews:							# loop on all subviews of main view
		if 'TextField' in str(type(sv)):		# subview is a TextField
			tfo = ObjCInstance(sv).textField()# get ObjectiveC object of sv
			tfo.setInputAccessoryView_(vo)		# attach our accessory to textfield

	main_view = ui.View()
	main_view.name = 'NextFieldKeyInTextFieldKeyboard'
	main_view.frame = (0,0,280,140)
	main_view.add_subview(ui.TextField(frame=(10,  2,260,32)))
