Using SSK2 features I’d do this:
io.output():setvbuf("no") display.setStatusBar(display.HiddenStatusBar) -- ===================================================== require "ssk2.loadSSK" \_G.ssk.init( { measure = false } ) -- ===================================================== -- -- This is 'helper' code made to simplify and homogenize making multiple fields -- that auto-save changes and auto-restore them on next-load. -- local persist = ssk.persist local fields = {} local function userInput( self, event ) if ( event.phase == "began" ) then elseif ( event.phase == "ended" or event.phase == "submitted" ) then persist.set( "fieldValues.json", self.\_id, self.text ) elseif ( event.phase == "editing" ) then persist.set( "fieldValues.json", self.\_id, self.text ) end return false end local function makeField( x, y, w, h, id, params ) params = params or {} -- local field = native.newTextField( x, y, w, h ) field.\_id = "field\_" .. id field.userInput = userInput field:addEventListener( "userInput" ) for k,v in pairs(params) do field[k] = v end -- Restore prior value for this field if it exists -- local restoreValue = persist.get( "fieldValues.json", field.\_id ) or "" field.text = restoreValue -- return field end -- -- Now use the helper from above to make some fields -- local label = display.newText( "User Name:", centerX - 160, centerY - 30, nil, 20) label.anchorX = 1 local userName = makeField( centerX, label.y, 300, 40, 'userName' ) local label = display.newText( "Password:", centerX - 160, centerY + 30, nil, 20) label.anchorX = 1 local password = makeField( centerX, label.y, 300, 40, 'password', { isSecure = true } )
