Non-arc modeRetain: When the variable is a pointer type, it needs to be retain decorated, and the reference series increases by 1 when using the Setter method (Assignment).Assign: Modifies a variable of a non-pointer type and ID type, such as Nsinteger,cgfloat, or delegate3.

ARC is not used for newly created projects using cocos2d 2.x. Therefore, to save the manual memory management, it is necessary to use arc to improve coding efficiency.CodeArc conversion.
After reading some tutorials, some of them are very difficult to write. Later I found that arc conversion is too easy, as long as I
Arc length of §6.4 plane curve
I. The case of rectangular coordinates
The function has the first order successive derivative on the interval, calculates the curve length.
If the integral variable is taken, the length of the curve arc segment corresponding to the small interval can be approximated by its arc differential.
So, the
There are two ways to convert non-ARC Code to ARC Code: 1. use Xcode's automatic conversion tool 2. manually set certain files to support ARC 1. Xcode's automatic conversion tool Xcode provides an automatic conversion tool to convert the old source code to the ARC Mode 1.

A memory leak has occurred! */Circular references are prone to memory leaks, so-called memory leaks mean that objects that should be discarded persist beyond their lifetimes.As in this case, there is only one object, but a circular reference occurs when the object holds itself.

Compile the hadoop 2.x Hadoop-eclipse-plugin plug-in windows and use eclipsehadoopI. Introduction
Without the Eclipse plug-in tool after Hadoop2.x, we cannot debug the code on Eclipse. We need to package MapReduce of the written java code into a jar and then run it on Linux, therefore, it is inconvenient for us to debug the code. Therefore, we compile an Eclipse plug-in so that we can debug it locally. Afte
