Question

For text bozo__foo!!bar.baz, how to split an NSString containing this into (bozo, foo, bar, baz)?

That is, separe it in components with strings (delimiters) __, !! and ..

Answer 1

You can split the strings using NSCharacterSet. Try this

NSString *test=@"bozo__foo!!bar.baz";
NSString *sep = @"_!.";
NSCharacterSet *set = [NSCharacterSet characterSetWithCharactersInString:sep];
NSArray *temp=[test componentsSeparatedByCharactersInSet:set];
NSLog(@"temp=%@",temp);
