本文介绍了如何创建自定义输入源，包括定义所需处理的信息、设置调度程序以便客户端联系输入源，以及如何在客户端传递数据后唤醒输入源的运行循环。文章还详细解释了在指定时间到期后如何使输入源无效并通知客户端。

Creating a custom input source involves defining the following:

The information you want your input source to process.
A scheduler routine to let interested clients know how to contact your input source.

After it hands off its data to the input source, a client must signal the source and wake up its run loop.
Signaling the source lets the run loop know that the source is ready to be processed
you should always wake up the run loop explicitly

tips
when the allotted time expires,the run loop call CFRunLoopSourceInvalidate to invalidate all the source0(at the same time invoke cancellation routine to inform the client)
CFRunLoopSourceInvalidate removes source from all the run loop modes in which it was registered.
