Obj-C通过tcp套接字为iphone发送和接收数组。

Question

我想弄清楚如何以及如果你可以通过TCP套接字发送和接收数组。我在C目标上有点新手，但我已经能够发送和接收字符串。我只想让它现在做数组。

(void)stream:(NSStream *)theStream handleEvent:(NSStreamEvent)streamEvent { 

NSLog(@"stream event %i", streamEvent); 

switch (streamEvent) { 

    case NSStreamEventOpenCompleted: 
     NSLog(@"Stream opened"); 
     break; 
    case NSStreamEventHasBytesAvailable: 

     if (theStream == inputStream) { 

      uint8_t buffer[1024]; 
      int len; 

      while ([inputStream hasBytesAvailable]) { 
       len = [inputStream read:buffer maxLength:sizeof(buffer)]; 
       if (len > 0) { 
        output = [[NSString alloc] initWithBytes:buffer length:len encoding:NSASCIIStringEncoding]; 

        if (nil != output) { 



         chSent = [output substringWithRange: NSMakeRange (0, 6)]; 

         dimensionString = [output substringWithRange: NSMakeRange (7, 3)]; 
         colorString = [output substringWithRange: NSMakeRange (7, 3)]; 


         if ([chSent isEqualToString:@"dimen:"]) 
         { 

          dimensionInt = [dimensionString intValue]; 

         } 

         if ([chSent isEqualToString:@"color:"]) { 

          // insert array named color in here some how 

         }         


        } 
       } 
      } 
     } 
     break; 


    case NSStreamEventErrorOccurred: 

     NSLog(@"Can not connect to the host!"); 
     break; 

    case NSStreamEventEndEncountered: 

     [theStream close]; 
     [theStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; 
     // [theStream release]; 
     theStream = nil; 

     break; 
    default: 
     NSLog(@"Unknown event"); 
} 
} 

那是什么我有。 其中我已经把/ /插入数组是我想要把它

如果你可以提前致谢。

您可以将数组数据（例如整数）作为字符串分隔，分隔符为“color：1; 2; 3; 4;”然后将这些字符串分开。如果你需要传递更复杂的数据结构，你可以编码，发送，解码。看看那个NSKeyedArchiver类。
