Question

Example of what I am trying to do:

String = "2 A2 E10 string"

E10 is not fixed. it may be E222 0r E1 but starting letter E is fixed.

I am looking to get this as a result: "E10"

I am struggling with objective-c and strings for some reason

Answer 1

If you are sure that there are words like “2”, “A2” and “E10” in the string separated by whitespaces and you want the last string, you can use,

NSString *string = @"2 A2 E10";
NSArray *words = [string componentsSeparatedByString:@" "];
NSString *lastWord = [words lastObject];
