Getting the substring from a certain character in NSString

Question

If I have an NSString that is initially:

"ABCDE*FGHI"

How do I make it turn into

"FGHI"

In other words, everything from the asterisk onwards is kept.

Likewise, how would I turn it into:

"ABCDE"

(everything up to the asterisk is kept)

Thanks

Answer 1

NSString *myString = @"ABCDE*FGHI";
NSString *subString = [myString substringWithRange: NSMakeRange(0, [myString rangeOfString: @"*"].location)];

Answer 2

NSString *myString = @"ABCDE*FGHI"; 
NSArray *myArray = [myString componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"*"]];

• key 0 of myArray will contains @"ABCDE"
• key 1 will contains @"FGHI"
