我似乎对这种一般方法有疑问。问题出在行[（TCPClient *）tcpClient connectHost：@“localhost”port：5000];
-(IBAction) asClientClicked:(id)sender{
if(tcpClient) {
if([tcpClient respondsToSelector:@selector(setShouldKeepRunning:)])
[(TCPServer *)tcpServer setShouldKeepRunning: NO];
[tcpClient release];
}
tcpClient = [[TCPClient alloc] initWithDelegate:self];
[(TCPClient *) tcpClient connectHost: @"localhost" port:5000];
mTextView.text = @"Client Waiting";
}
我认为上面的tcpClient配置存在问题。这是initWithDelegate方法，但我没有看到它的问题。
- (TCPClient *) initWithDelegate: (id) delegate
{
self = [super init];
[self setTheDelegate: delegate];
NSLog (@"Creating socket.");
socket = [[AsyncSocket alloc] initWithDelegate:self];
return self;
}
感谢。

你的问题就在这些方面，
if([tcpClient respondsToSelector:@selector(setShouldKeepRunning:)])
[(TCPServer *)tcpServer setShouldKeepRunning: NO];
[tcpClient release];
您正在检查tcpClient是否能够回复setShouldKeepRunning:并稍后在tcpServer上调用它。在崩溃时，tcpServer不是nil，无法回复setShouldKeepRunning:。你可能意味着tcpClient。根据需要调整代码。
