how to print out UInt16 pointer to NSLog

I am just trying to print out UInt16 pointer to my log, So i can see its contence... however thus far am not having any sucsess, dose anyone know how to do this, I am thinking its the format specifier but because I dont have alot of experience with this type of thing I just dont know. the warning I am getting is "initialization discards qualifiers from pointer target type"

//....
    [nissanCode seekToFileOffset: 2];
    dataBuffer = [nissanCode readDataOfLength:SETSIZE];
    UInt16 *ans = dataBuffer.bytes;
    UInt16 a = *ans;
    NSLog (@"Data = %@", a);
//....

//Revised code that clears the warning and prints data out fine. thanks f开发者_StackOverflow社区or the help guys.

//....
    [nissanCode seekToFileOffset: 2];
    dataBuffer = [nissanCode readDataOfLength:SETSIZE];
    const UInt16 *ans = dataBuffer.bytes; 
    NSLog (@"Data = %d", a);
//....

try using for int's

NSLog(@"Data = %d", a);

or for your UInt16's (thanks to @bshirley for the list of format specifiers below)

NSLog(@"Data = %hu", a);

Are you trying to print the address or the value? From how your code is setup you should be using %d, but for the pointer you would use NSLog("%p", ans);. The %@ format is for objects only.
