Now I want to develop a safari plugin use SIMBL , but I searched a lot of webpage not found some sourcecode or simple sample , someone can give me or point to a location ? Thank you very much!!!
Did you consider writing a WebKit Plugin?
As far as I understand, SIMBL plug-ins are still some kind of Input Manager and therefore not well supported on new Mac OS X versions, and not supported at all if Safari runs as 64-bit process.
A good starting point to write a WebKit plug-in: Creating Plug-ins with Cocoa and WebKit
You can also peek into the ClickToFlash source.
ClickToFlash is implemented as WebKit plug-in.
