Could you just add each dictionary to a single dict and then have a
globally unique set of keys? This would presuppose you know which
value of testKey is the one you wan to retain, and you'd add that one
last.

Hi All,
Is there a way to remove dictionary item containing same values for
a key
from a array of dictionaries?
E.g.
NSDictionary *dict1 = [NSDictionary dictionaryWithObjectsAndKeys:@
"testVal",@"testKey",....,nil];
NSDictionary *dict2 = [NSDictionary dictionaryWithObjectsAndKeys:@
"testVal1",@"testKey",....,nil];
NSDictionary *dict3 = [NSDictionary dictionaryWithObjectsAndKeys:@
"testVal3",@"testKey",....,nil];
NSDictionary *dict4 = [NSDictionary dictionaryWithObjectsAndKeys:@
"testVal",@"testKey",....,nil];
NSArray *arrDicts = [NSArray
arrayWithObjects:dict1,dict2,dict3,dict4,nil];
In the above code I want to remove the multiple dictionaries
containing
"testVal" and maintain only one dictionary containing "testVal" in
the array
"arrDict".
