Find and Replace question NSArray

An NSArray arr = {@ "aa", @ "bb" @ "cc", "dd", @ "aa", @ "dd", @ "cc", @ "aa"};

Want to convert NSArray arr = {@ "aa", @ "bb" @ "cc", "dd", @ "aa1", @ "dd1", @ "cc1", @ "aa2"};

Is repeated to add the next int type distinction, God horse good way?

I recommend you a way:

 
# Define format (fmtString, args ...) [NSString stringWithFormat: fmtString, args] 
NSArray * arr = @ [@ "aa", @ "bb", @ "cc", @ "dd", @ "aa", @ "dd", @ "cc", @ "aa"]; 

NSMutableDictionary * dict = [NSMutableDictionary dictionary]; 
for (NSString * value in arr) 
{
[Dict setObject: @ "-1" forKey: value]; 
} 

NSMutableArray * finalArray = [NSMutableArray array]; 
for (NSString * value in arr) 
{
for (NSString * key in dict) 
{
if ([value isEqualToString: key]) 
break; 
} 
dict [value] = format (@ "% d", [dict [value] intValue] +1); 

? NSString * obj = (! [Dict [value] intValue]) format (@ "% @", value): format (@ "% @% d", value, [dict [value] intValue]); 

[FinalArray addObject: obj]; 
} 

NSLog (@ "% @", finalArray);

Thank you very much for the object is not enough to grasp such an approach can not think of a good way
