Cocoa has always been lacking in the RegEx department (at least the
'built-in' Cocoa classes, there's a bunch of third-party regex
frameworks), especially when compared to languages like Python. Since
your situation isn't very complex, I would just use the bread-n-butter
string APIs:
NSString *originalString = @"everything_else_is_my_name";
NSArray *originalStringComponents,
*resultingComponents;
NSMutableString *result = [NSMutableString string];
originalStringComponents = [originalString
componentsSeparatedByString: @"_"];
for (NSString *currentStringComponent in originalStringComponents)
[result appendString: [NSString stringWithFormat: @"%...@%@",
[currentStringComponent capitalizedString],
(currentStringComponent != [originalStringComponents lastObject] ? @"
" : @"")]];
NSLog(@"%@", result);
(Better-formatted version here: http://pastie.org/444173).
Note that this snippet isn't incredibly efficient, but should get the
point across...
