iPhone：无法识别的选择错误

Question

我threeaing一些这样的任务：

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]; 
} 

给

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

问题是什么？

Answer 1

线程无关紧要。您没有向我们展示的部分代码正在实现，因此您要将foundSomething:选择器发送给不处理该消息的对象。将消息路由到处理它的对象，并且问题将消失。请参阅"Unrecognized selector sent to instance"。
