TiViewShadow Module

Description

This module extends the Ti SDK, allowing to add "drop shadow" functionalities to any View object you create.

The code implementing this feature has been originally posted by Javier Rayon here.

The module is licensed under the MIT license.

TITANIUM 2 SUPPORT: Titanium 2 introduces some breaking layout changes. On iOS, now views are clipped to their bounds. Since shadows are dropped outside the view bounds, this affects seriously to this module. We tried to avoid this behavior, but in some cases the shadow does not work as expected. While we find a solution, consider that in these cases:

  • Using Ti.UI.SIZE in a parent view, could cut the shadows of its children.
  • A view with solid background and with children views can not drop shadow itself (but the children will do)

Building and installing the TiViewShadow Module

BUILD

First, you must have your XCode and Titanium Mobile SDKs in place, and have at least read the first few pages of the iOS Module Developer Guide from Appcelerator.

The build process can be launched using the build.py script that you find in the module's code root directory.

As a result, the ti.viewshadow-iphone-0.4.zip file will be generated.

NOTE: if your Titanium sdk resides in the root /Library/Application Support/Titanium/ directory, you need to change the value of the TITANIUM SDK variable in titanium.xcconfig

INSTALL

You can either copy the module package (ti.viewshadow-iphone-0.4.zip) to $HOME/Library/Application\ Support/Titanium and reference the module in your application (the Titanium SDK will automatically unzip the file in the right place), or manually launch the command:

 unzip -uo ti.viewshadow-iphone-0.4.zip -d $HOME/Library/Application\ Support/Titanium/

NOTE: if your Titanium sdk resides in the root /Library/Application Support/Titanium/ directory, change the above command accordingly

Referencing the module in your Titanium Mobile application

Simply add the following lines to your tiapp.xml file:

<modules>
    <module version="0.4" platform="iphone">ti.viewshadow</module> 
</modules>

and add this line in your app.js file:

require('ti.viewshadow');

The module provides no public api. It's simply used for extending the TiUIView class provided by the Ti SDK with additional functionality.
