NSString question - rangeOfString method

Question

I am having an issue that I can\'t figure out.

I\'m trying to run the rangeOfString method on a string, and I\'m not sure how to determine if the string was not foun

Answer 1

From the documentation of NSString

-[NSString rangeOfString]

Return Value

An NSRange structure giving the location and length in the receiver of the first occurrence of aString. Returns {NSNotFound, 0} if aString is not found or is empty (@"").

So it looks like:

if ([@"abc" rangeOfString:@"d"].location == NSNotFound){
  //Do something

Is the Apple-approved way.

EDIT:

I made a really bad typo, fixed it, thanks Kalle.

Answer 2

Check the length of the range. If it's non-zero, it was found.
