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

Answer 1

Try stringByReplacingOccurrencesOfString:withString:.

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