Question

NSLog中的错误：

*** -[NSThread initWithTarget:selector:object:]: target does not implement selector (*** -[Document myTcpClient])

代码：

-(void) myTcpStart: (NSButton*) button{   
    //need threads for the following
    thread_Client = [[NSThread alloc] initWithTarget:self selector:@selector(myTcpClient) object:nil];
    thread_Display = [[NSThread alloc] initWithTarget:self selector:@selector(displayData) object:nil];

    [thread_Client start];
    [thread_Display start];

    [textField1 setStringValue:@"waiting for threads to run"];
}


-(void) myTcpStop: (NSButton*) button{   
    //need threads for the following

    //[thread_Client cancel];
    //[thread_Display cancel];
}

-(void) displayData{
    while(1){   
        [textField1 setStringValue:[NSString stringWithFormat:@"%d %d %f", j, i, genValue]];
        j++;
    }
}

-(void) myTcpClien{
    //some code
}

头文件：

#import <Cocoa/Cocoa.h>

@interface Document : NSDocument
{
    NSTextField *textField1;
    int i;
    int j;
    double genValue;
    NSWindowController *bController;
    NSThread *thread_Client;
    NSThread *thread_Display;
}

-(void) myTcpClient;
-(void) displayData;

-(void) myTcpStart: (NSButton*) button;
-(void) myTcpStop: (NSButton*) button;

@end

你在myTcpClient实现中忘记了T.再次看到这些消息时，请检查代码是否存在拼写错误。

变化：

- (void)myTcpClien { /* ... */ }

要：

- (void)myTcpClient { /* ... */ }

NSLog：线程错误
