Objective C TCP Socket

Question

我试图绕过目标c tcp套接字连接到服务器，我使用了这两个教程中的代码：https://www.raywenderlich.com/3932/networking-tutorial-for-ios-how-to-create-a-socket-based-iphone-app-and-server和https://gist.github.com/rjungemann/446256。我注意到，当我尝试将数据发送出去时，直到我停止应用程序（在服务器上接收到该点）之前，在遵循两个教程时，在相关代码下面的行为相同：

- (void)setup {
    NSURL *url = [NSURL URLWithString:host];

    NSLog(@"Setting up connection to %@ : %i", [url absoluteString], port);

    CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, (__bridge CFStringRef)[url host], port, &readStream, &writeStream);

    if(!CFWriteStreamOpen(writeStream)) {
        NSLog(@"Error, writeStream not open");

        return;
    }
    [self open];

    NSLog(@"Status of outputStream: %lu", (unsigned long)[outputStream streamStatus]);

    return;
}

- (void)writeOut:(NSString *)s {
    uint8_t *buf = (uint8_t *)[s UTF8String];

    [outputStream write:buf maxLength:strlen((char *)buf)];

    NSLog(@"Writing out the following:");
    NSLog(@"%@", s);
}
