How do you convert an unsigned char array to an NSData in objective c?
This is what I am trying to do, but it doesn't work. Buffer is my unsigned char array.
NSData *data = [NSData dataWithBytes:message length:length];
You can just use this NSData class method
+ (id)dataWithBytes:(const void *)bytes length:(NSUInteger)length
Something like
NSUInteger size = // some size
unsigned char array[size];
NSData* data = [NSData dataWithBytes:(const void *)array length:sizeof(unsigned char)*size];
You can then get the array back like this (if you know that it is the right data type)
NSUInteger size = [data length] / sizeof(unsigned char);
unsigned char* array = (unsigned char*) [data bytes];
