1342+
1343+
Demonstrates how to implement UIWebView with a transparent background.
1344+
1345+
To achieve this you need to make the HTML body's background color transparent by doing the following -
1346+
1347+
1) set the UIWebView's backgroundColor property to [UIColor clearColor]
1348+
1349+
2) use the UIWebView's content in the html: <body style="background-color: transparent">
1350+
1351+
3) the UIWebView's opaque property set to NO
