When Elipse is a Java project, there is a very user-friendly "task management" feature that makes it easy to document some of the tasks in the project that need to be handled. Let's take a look at how "task management" is used.The following class adds a section of Fixme and Todo tags to the comment of the class and name properties, and the Fixme and TODO tags also follow a text to illustrate what needs to b

In xcode 3, we can use annotations like this to easily mark the parts to be modified:

Xcode 4 does not support this function. There is a solution on the Internet to forward it:

essentially executed only once, but such a design allows the client to retry multiple times, seemingly as a idempotent operation.
The basic idea of how to implement a idempotent operation is to get a transaction ID and use this ID to record whether the operation has been executed. Each time the client tries to take the money with this ID, the server will know whether the transaction has been executed.My question is, when will the server be able to erase these transaction ID data? or keep it?
