[問題] leak of NSThread

[lemonstar (筆記本)]

在Stanford教學中
http://www.stanford.edu/class/cs193p/cgi-bin/index.php

有篇NSThrad的Sample : Lecture 10  - LetsMakeAThread

Sample Code連結 :
http://www.stanford.edu/class/cs193p/downloads/10-LetsMakeAThread.zip

他的架構大致如下 :

1. Thread進入點:

[NSThread detachNewThreadSelector:@selector(someFunction)
 toTarget:self withObject:nil];

(說明文件有提到,"detachNewThreadSelector:.." method中,
 selector function 必須自訂一個autoreleasepool )


2.someFunction 內容: (沒忘了加autoreleasepool)

-(void)someFunction{

  NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
  [NSThread sleepforTimeInterval:3];
  [self performSelectorOnMainThread:@selector(finishFunction) withObject:nil
   waitUntilDown:NO];
  [pool release];

}

3.end:
 -(void)finishFunction{
   ...................
}


問題來了,當我把它放上實機跑Insttrument,就出現一根memory leaks
(General Block - 3584)

情形大致就與這篇論壇的情形一樣(有畫面)

用這個method去啟動新的NSThread,每啟動一個都會出現memory leak...
不知有無解決之道 :(
