for (int i=0; i<[string length]; i++) {
   char = [string characterAtIndex:i];
   NSString *charString = [NSString stringWithFormat:@"%c", char];
   if ([charString isEqualToString:comparisonString]) {
      //match
   }
   else {
      //no match
   }
}

Use characterAtIndex: function of NSString to extract the character by index.

- (unichar)characterAtIndex:(NSUInteger)index

if you want to compare a string. Using isEqualToString method.

NSMutableString *str = [[NSMutableString alloc] initWithString:@"a"];
if([str isEqualToString:@"a"]){
  // match
}
else{
  // not match
}
