Question

How would I get the last occurrence of an NSString within another NSString? For example, in “abc def ghi abc def ghi,” I want to find the index of the second “abc,” not the first. I know I could do this with a bunch of rangeOfStrings, but is there already a function for that?

Answer 1

Use rangeOfString:options:, including NSBackwardsSearch in the options.

[@"abc def ghi abc def ghi" rangeOfString:@"abc" options:NSBackwardsSearch];
