Appcelerator Titanium Useful Marcos and alias

Published on June 5, 2012 by in Titanium

Appcelerator Titanium SDK is purely JavaScript platform. So, Web developers can also create native application for top SmartPhone OS Android and iOS, HTML5 (Mobile Web). Now Titanium beta released for Blackberry also. I hope soon I can see my favorite OS Windows Phone in that list.

Appcelerator Titanium

Appcelerator team created few marcos for us, to minimize keystrokes. Here is the list of Marcos :-

1) Ti is alias for Titanium

For example :- We can use Ti.API.info("prints info message"); instead of Titanium.API.info("prints info message");

2) L is for get locale string

For example :- We can use L("welcome"); instead of Ti.Locale.getString("welcome");

This above method is using for localization string. It will automatically brings the give key name value for strings.xml for the language folder (en|es|ja…) in side i18n folder.

Remember one thing it is also best to pass default value to this getString method. So, if there is no key match it will return this default value. This is how we have to do Ti.Locale.getString("welcome","Hello ");

3) alert is alias of Titanium.UI.createAlertDialog for single message.

AlertDialog is used for show dialog box with multiple buttons (for E.g. Ok Cancel or Yes, No, Cancel).

alert is also default method of Javascript. alert("This default alert"); This will show dialog box with only Ok button.

var dialog = Ti.UI.createAlertDialog({ cancel: 1, buttonNames: ['Confirm', 'Cancel', 'Help'], message: 'Would you like to delete the file?', title: 'Delete' }).show();

dialog.addEventListener(‘click’, function(e) {
//Clicked cancel, first check is for iphone, second for android
if (e.cancel === e.index || e.cancel === true) {
return;
}
//now you can use parameter e to switch/case
switch (e.index) {
case 0:
//Do something here
break;
:
}
}
