objective c - Defeating the "multiple methods named 'xxx:' found" error -

In my existing project in File ViewController.m, I am running the method:

  [[Connection Writer] Write Data: Data];  

This warns:

  Warning: Several methods were found in the name of 'writeData:'  

I To call the method trying to:

  - (zero) write data: TCPRIR in (NSDT *) data   
 .... M. Unfortunately, there are two other  writing data  methods  
  - (zero) write data: (NSDT *) data;  
 
 ... nsfile in handheld and ... 
 
  - Writing data: (NSDT *) data   
 ... in NSURLHandle.h. This is especially confusing to me because the  [conn writer]  should return the  TCPWriter  class and correct that class to the right  writeData  method Besides calling, I am not entirely sure that NSFillHandleH and NSURHRWHDLH have been included in any library included in the visual controller instead of any part of the project.  
 How can I show the compiler that I want to call the  writeData  method and why is this error?  
 
 
 Be sure that [connection author] is actually returning a TCPWriter * if it returns an ID , The compiler will not know which data to use the data. Also, make sure that you are importing the TCPRRH file - if the compiler does not see the header files, then it will default to returning id, which will return you to the same problem.  
 Try  
  TCPDriver * Author = [Connection Writer]; [Write author: data];  
 
 or 
 
  [(TCPR author *) Write [connection author] data: data];
