NSData not working correctly

Question

NSData *myRequest = [NSString stringWithFormat:(@"&site=%@&key=%@",tmpSite,tmpKey)];

Why is this not working ?

Thanks

Answer 1

Problem is that you are assigning NSString instance to variable of NSData type. Try this:

NSString* s = [NSString stringWithFormat:@"&site=%@&key=%@",tmpSite,tmpKey];
NSData* d = [s dataUsingEncoding:NSASCIIStringEncoding]; //or any other encoding!

Answer 2

NSData *myRequest = [[NSString stringWithFormat:(@"&site=%@&key=%@",tmpSite,tmpKey)] dataUsingEncoding: NSASCIIStringEncoding];

You can't just mix the two classes like that.
