I have a few methods that return NSData objects, but the objects are
created and manipulated as NSMutableData, and then copied to an
immutable version along these lines:
NSMutableData *myData = [NSMutableData data];
:
:
return [NSData dataWithData:myData];
Would it be sufficient to cast, like this?
:
return (NSData *)myData;
Does this generalize to other non-collection classes, e.g., NSString?
TIA.
