TransWeb

Demonstrates how to implement UIWebView with a transparent background.

To achieve this you need to make the HTML body's background color transparent by doing the following -

1) set the UIWebView's backgroundColor property to [UIColor clearColor]

2) use the UIWebView's content in the html: <body style="background-color: transparent">

3) the UIWebView's opaque property set to NO

Build Requirements

iOS 4.0 SDK

Runtime Requirements

Using the Sample

Launch the TransWeb project using Xcode.

To run in the simulator, set the Active SDK to Simulator. To run on a device, set the Active SDK to the appropriate Device setting.  When launched scroll vertically through the web content and observe the transparent background image.
