這是代碼：

func stream(aStream: NSStream, handleEvent eventCode: NSStreamEvent) { 
    switch(eventCode){ 


    case NSStreamEvent.HasBytesAvailable: 

     var buffer = [UInt8](count: 4096, repeatedValue: 0) 


     if (aStream == GlobalVariables.inputStream){ 

      while (GlobalVariables.inputStream!.hasBytesAvailable){ 
       let len = GlobalVariables.inputStream!.read(&buffer, maxLength: buffer.count) 
       if(len > 0){ 
        let output = NSString(bytes: &buffer, length: buffer.count, encoding: NSUTF8StringEncoding)!.stringByTrimmingCharactersInSet( 
         NSCharacterSet.whitespaceAndNewlineCharacterSet()) 
        if (output != ""){ 
         / 

         / 
         var buf = UnsafeMutablePointer<CChar>(buffer) 

         var bufString: String = String.fromCString(buf)! 

         if ((delegate) != nil){ 
          delegate!.dataReceived(bufString) 
         } 

        } 
       } 
      } 


     } 


     break 

    case NSStreamEvent.OpenCompleted: 

     break 

    default: break 

    } 


}

如果你想執行backSegue Segue公司？ –

在另一個視圖控制器中的dataReceived函數內 –

顯然你不是呼喚g正確的對象上你的繼續。請確保您在正確的對象上調用performSegueWithIdentifier:函數。例如：

這是正確的：

[self performSegueWithIdentifier:@"backSegue" sender:self];

這是不正確的：

[self.navigationController performSegueWithIdentifier:@"backSegue" sender:self];

不，我使用self.performSegueWithIdentifier（「backSegue」，發件人：自我），所以它應該工作：/ –
