How to convert byte array to NSString

Question

I am reading data from a TCP/IP stream and am successfully receiving a byte array from the pre-existing server. I am now trying to find a way to convert that array to an NSString. I have found several examples, but am having a hard time getting my desired results.

NSData *data=[[NSMutableData alloc] init];

uint8_t buffer[1024];
unsigned int len=0;

len=[(NSInputStream *)stream read:buffer maxLength:1024];
if(len>0){  

    [data appendBytes:&buffer length:len];
    //BYTE ARRAY OBTAINED OK!!
    ///////////////////////////////////////////////////////

    //METHOD #1 - Yields 'nil'
    NSString *string = [[NSString alloc] initWithData:data
                                             encoding:NSUTF8StringEncoding];

    ///////////////////////////////////////////////////////
    //METHOD #2 - Log prints OK, but messageString says
    //'invalid' in debugger, and get warnings all over the 
    //place. I know this is wrong, but it semi-works :)

    size_t length=[data length];
    unsigned char aBuffer[length];
    [data getBytes:aBuffer length:length];
    aBuffer[length - 1]=0;

    NSString *messageString =aBuffer; 
    NSLog (@"%s",messageString);

    ///////////////////////////////////////////////////////

}else{
    NSLog(@"No Buffer");
}

Please help! Any assistance provided is GREATLY appreciated.

I got the answer.

I had to change this:

NSString *string = [[NSString alloc] initWithData:data
                                         encoding:NSUTF8StringEncoding];

To this:

NSString *string = [[NSString alloc] initWithData:data
                                         encoding:NSASCIIStringEncoding];
