Character occurrences in a String Objective C

Question

How can I count the occurrence of a character in a string?

Example

String: 123-456-7890

I want to find the occurrence count of \"-\

Answer 1

The current selected answer will fail if the string starts or ends with the character you are checking for.

Use this instead:

int numberOfOccurances = (int)yourString.length - (int)[yourString stringByReplacingOccurrencesOfString:@"-" withString:@""].length;
