TiGrowingTextField Appceleartor Titanium iOS Module

Description

This simple module let's you create a text field which grows or shinks depending on the the content the user types, like iMessage, WhatsApp, etc.

TiGrowingTextField uses a third party library created by HansPinckaers: https://github.com/HansPinckaers/GrowingTextView/

And it's open sourced: https://github.com/iamyellow/TiGrowingTextField

Using the module

Require the module and call and create the view:

var textField = require('net.iamyellow.tigrowingtextfield').createView({
	// layout stuff -it works as any other view-
	height: 40, // 40 is the minimum height, the view height won't be < 40
	left: 10, right: 10,
	// layout correction (new since v0.5)
	topCorrectionPadding: 7,
	sidesPadding: 5,
	// growing / shrink
	minNumberOfLines: 1, // default = 1
	maxNumberOfLines: 10, // default = 3,
	showKeyboardImmediately: true,
	// background stuff
	backgroundImage: 'images/MessageEntryInputField.png',
	backgroundLeftCap: 12,
	backgroundTopCap: 20,
	value: 'hellow',
	// appearance 
	appearance: Ti.UI.KEYBOARD_APPEARANCE_ALERT,
	// text stuff, works as Ti.UI.TextField
	autocorrect: false, // disables / enables autocorrection
	textAlign: 'left',
	font: {
		fontFamily: 'Georgia',
		fontSize: 12
	},
	color: '#333333'
});

I guess properties names are self explanatory, except showKeyboardImmediately... well, sometimes I need the keyboard appears immediately as window is opened. Setting this to true makes it possible.

Methods

focus ()

The field gains the focus.

blur ()

The field loses the focus.

Events

focus

When it gains the focus.

blur

When it loses the focus.

change

When the content changes. The event has properties:

• value the content itself, the text field value.

• height the current height.

Example

(function (tigrowingtextfield) {	
	// ****************************************************************************************************************
	// ****************************************************************************************************************
	// GUI setup
	
	var win = Ti.UI.createWindow({
		width: Ti.UI.FILL, height: Ti.UI.FILL,
		backgroundColor: '#fff612'
	}),
	toolbar = Ti.UI.createView({
		width: Ti.UI.FILL, height: Ti.UI.SIZE,
		top: 30, left: 0,
		backgroundImage: 'images/MessageEntryBackground.png',
		backgroundTopCap: 20
	}),
	// layout correction values 
	minHeight = 40,
	topCorrectionPadding = 7,
	sidesPadding = 5,
	// create view
	textField = tigrowingtextfield.createView({
		// layout, as any other view
		height: minHeight, // 0.5: once the view is inited, this is going to be the MIN height
		top: 0, left: 10, right: 10,
		// fine-tuning text adjustment (new on 0.5)
		topCorrectionPadding: topCorrectionPadding,
		sidesPadding: sidesPadding,
		// growing / shrink
		minNumberOfLines: 1, // default = 1
		maxNumberOfLines: 5, // default = 3,
		showKeyboardImmediately: true,
		// background
		backgroundImage: 'images/MessageEntryInputField.png',
		backgroundLeftCap: 15,
		backgroundTopCap: 20,
		// appearance 
		appearance: Ti.UI.KEYBOARD_APPEARANCE_ALERT,
		// text
		autocorrect: false,
		textAlign: 'left',
		font: {
			fontFamily: 'Helvetica',
			fontSize: 12
		},
		color: '#333'
	});
	
	toolbar.add(textField);
	win.add(toolbar);
	
	// ****************************************************************************************************************
	// ****************************************************************************************************************
	// events
	
	win.addEventListener('click', function () {
		textField.blur();
	});
	
	textField.addEventListener('focus', function (ev) {
		Ti.API.info('////////////////////////////////////////////////////////////');
		Ti.API.info('** focused');
	});
	
	textField.addEventListener('change', function (ev) {
		Ti.API.info('////////////////////////////////////////////////////////////');
		Ti.API.info('my value is: ' + ev.value);
		Ti.API.info('my height is: ' + ev.height);
	});
	
	textField.addEventListener('blur', function (ev) {
		Ti.API.info('////////////////////////////////////////////////////////////');
		Ti.API.info('** blurred');
	});
	
	
	// ****************************************************************************************************************
	// ****************************************************************************************************************
	// the show
	
	win.open();
})(require('net.iamyellow.tigrowingtextfield'));
