iPhone：无法识别的选择器错误 [英] iPhone: unrecognized selector error

问题描述

我正在做一些像这样的任务：

I'm threeaing some tasks like this :

- (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

oneObject

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

给出

gives

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

问题是什么？

推荐答案

线程无关紧要。你没有向我们展示的一些代码是这样做的，所以你将 foundSomething：选择器发送给一个不处理该消息的对象。将邮件路由到处理邮件的对象，问题就会消失。

The threading is irrelevant. Some of the code you're not showing us is making it so you are sending the foundSomething: selector to an object that doesn't handle that message. Route the message to an object that does handle it, and your problem will go away.

另请参阅无法识别的选择器已发送到实例。
