[NSString dataUsingEncoding:] sometimes you have to look at the source object, not the destination (in fact usually, I'd say).
Also, in this case, [NSData initWithString:] would lack the information needed to perform the conversion - you need to pass in what encoding you require. --Graham On 17 May 2014, at 9:46 am, William Squires <wsqui...@satx.rr.com> wrote: > Why doesn't NSData have a +[NSData dataWithString:(NSString *)] or -[NSData > initWithString:(NSString *)] method? i.e. how do I convert the contents of an > NSString object into an NSData object?
