NSMutableData the right way?

I am having a function that is being called many times , it creates data to send to server via tcp. i think i am loosing the data somewhere .

I am wondering what is the right way to go :

  1. using finalData=[[NSMutableData alloc]init]; at the start of the program,and than the function to send is like (being call many times) :

    -(NSMutableData*)setProtocolDataForString:(NSString*)data{ 
finalData=nil;
//here construct new finalData..

or, whitin the function , retain it :

 -(NSMutableData*)setProtocolDataForString:(NSString*)data{

finalData=[[NSMutableData data]retain]; //but its wrong because it happens many times
//construct a finalData to send

I am not using ARC . First way crash, second way-i think i am loosing him ..

Should i use property? if yes, what is the exact way to do so ?

Ok, you are sending a chunk of data everytime you call 

 -(NSMutableData*)setProtocolDataForString:(NSString*)data;

You could do something like:

if(finalData){
 [finalData release];
 finalData = nil;
}

finalData = [[NSMutableArray alloc] init];
