Replace a substring with another substring

Question

Hi,

I want to replace the string "abc" to "def" each time it appears in my NSString object: "axcd abc amamam dff abc kdj abc"

How do I do that??

Thanks,

Sagiftw

Answer 1

Check out replacing regular expressions

Answer 2

Try stringByReplacingOccurrencesOfString:withString:.

NSString* foo = @"axvc abc amamam dff abc kjd abc";
NSString* bar = [foo stringByReplacingOccurrencesOfString:@"abc" withString:@"def"];
NSLog("%@", bar);

EDIT There was a typo in the method name. I've fixed it.
