Question

I have a NSString that I can decide the format for, in which I will store contact groups and group members, like so:

Friends|John Smith|Jane Doe
Imaginary Friends|Mary Poppins|Harry Potter|Arya Stark
(\n after last member name)

The “|” is a temporary divider I’m using because it is unlikely to appear in contact and group names.

I save this to file and need to extract the groups and group members names as NSStrings when I next load up this file. How would I do this?

Answer 1

I think you want to look at NSString method – (NSArray *)componentsSeparatedByCharactersInSet:(NSCharacterSet *)separator or – (NSArray *)componentsSeparatedByString:(NSString *)separator

e.g.

NSArray* members = [contactLine componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString: @"|"]];
