Detecting where a text is in text.

[mrPROgramer]

Hello,
I need to find a function that will find if something is in a text. For example, if there is a decimal then something would be true. I need to find the "." in any number like 65.435. If there is no decimal point like in 5, then the Boolean or whatever would be false.
Thank you

try rangeOfString. My code snippet is looking for 'fbid'. Should work for what you want.

    NSRange idRange = [pictureStr rangeOfString:@"fbid"];// position of string fbid 
// does the string contain fbid ? 
    if(idRange.length == 4)

NSRange idRange = [someString rangeOfString:@"."]; 
if(idRange. location != NSNotFound)
  //The string contains a decimal
else
  //The string DOES NOT contain a decimal
