iPhone：無法識別的選擇錯誤

Question

我threeaing一些這樣的任務：

RootViewController的

- (void)viewDidLoad { 
[NSThread detachNewThreadSelector:@selector(findSomething) toTarget:self withObject:nil]; 
} 

- (void) findSomething { 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
doMoreThings 
[pool release]; 
} 

- (void) doMoreThings { 
    doMoreMoreMoreThings on different objects 
} 

- (void) foundSomething:(NSFoundThing*)foundObj { 
    do your stuff 
} 

oneObject

- (void) doMoreMoreMoreThings { 
    do things 
[self performSelectorOnMainThread:@selector(foundSomething:) withObject:thingFound waitUntilDone:NO]; 
} 

給

-[KMLParser foundSomething:]: unrecognized selector sent to instance 0x5888080 

問題是什麼？

線程無關緊要。您沒有向我們展示的部分代碼正在實現，因此您要將foundSomething:選擇器發送給不處理該消息的對象。將消息路由到處理它的對象，並且問題將消失。請參閱"Unrecognized selector sent to instance"。
