It is well known that memory management in Objective-c is managed through a mechanism called "reference counters".For example, when I declare a new instanceNSData *data = [[NSData alloc] init]Now, there is an object of type NSData in memory called data. The value of its reference counter is 1. If I refer to it again, the value of his reference count will be +1 to 2.Call when you are finished using[Data release];Make the reference count-1.

Note: The implementation principle is to use PHP functions to read the data of text files, so as to achieve data statistics. 1. create a new file named counter. php. The code is as follows :? Php // select counter.txt.pdf file counter_file(counter.txt); // open the text file $ visitsfile ($ counter_file); // automatically add 1 EN "" http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">

There are three solutions to summarize the implementation of SharePoint counters:1. powerful functions, but operations are extremely complex. You can read the SharePoint log file and then display it as a chart style through owc11 (or reporting service). Because the log file records are very meticulous, so you can make a variety of charts, of course, you can also display a simple count,However, you need to create a schedule to read the data in the log file to your database and then present it.
