Use +[NSPropertyListSerialization dataWithPropertyList:format:options:error:] to convert the data, then check if the result -isKindOfClass:[NSArray class].

It will work :)

I have no idea what is inside your byte buffer. This code works for a simple buffer of character bytes.

Try: 

char buf[]="123456";
NSData *bufObj=[NSData dataWithBytes:(const void *)buf length:sizeof buf];
if(bufObj==nil)
    NSLog(@"failed to create obj");
else {
    NSMutableArray *marr=[NSMutableArray array];
    [marr addObject:bufObj];
    NSArray *arr=[NSArray arrayWithObject:bufObj];

    NSLog(@"test:\n\tbufObj: %@\n\tmarr: %@\n\tarr: %@",bufObj,marr,arr);
}
