runtime correlation principleRuntime involves a wide range of areas, this article only for the message delivery mechanism to expand this (finally began to focus ... )。 Okay, let's get to the point.In OC, when a method of an object is called, it essentially sends a message to the object, such as:
ID returnvalue = [someobject messagename:paramater];
The above example calls the MessageName: method of the Someobject object, passes in a para

You can conclude from the following example:1, figure one appears in three kinds of errors, respectively, in the Open/Create/Replace file function, write a text file function, read file file functions. Indicates that three functions have been run.2, figure two there is only one error, located in the Open/Create/Replace file function, the other two functions are not executed, indicating that the error chain is not only the delivery function, but also c

The problem is just about the Floyd for the transfer closure, because the problem is not a large amount of data, if the big estimate will use other methods. But this is, after all, a very simple and easy-to-write algorithm.After the delivery closure is found, the set will be merged with the person in a telephone ring, and the final output can be obtained.See the code for details:#include Copyright NOTICE: This article for Bo Master original article,
