NSString get -characters

Question

I want to get the characters of an NSString. Like this:

NSString *data;
const char * typein = [[data characters] UTF8String];

But obviously NSString won't respond to -characters. How do I get the characters of NSString?

thanks, Elijah

Answer 1

You can use this function:

for(int i =0 ;i<[myString length]; i++) {
  char character = [myString characterAtIndex:i];
}

or

NSString *str = @"astring";
const char *cString = [str UTF8String];

Answer 2

If you just want to get a cString from the NSString just call UTF8String as you are already doing and then iterate the array.
