Question

I have an array of NSDictionary.

NSDictionary*  dictionary = [NSDictionary dictionaryWithObjects:bothUserName forKeys:bothUID];  // here array "bothUserName" and "bothUID" is an NSArray type


[dictionary keysSortedByValueUsingSelector:@selector(compare:)];

NSLog(@" dictionary objects %@",dictionary);

I am getting an output like this.

dictionary objects {

 14172368 = webtickle;
271882407 = electrodealio;
314125883 = Coral5mz;
316212228 = ajaysinghHF2;
316348693 = Caroline99a;
43944597 = WorldStuffer;
 }

but I want to have output like this.

dictionary objects {

 316212228 = ajaysinghHF2;
316348693 = Caroline99a;
314125883 = Coral5mz;
271882407 = electrodealio;
14172368 = webtickle;
43944597 = WorldStuffer;
 }

Thanks in advance.

keysSortedByValueUsingSelector returns a sorted array containing dictionary’s keys, you have to use this returned array to retrieve the associated objects:

NSDictionary*  dictionary = [NSDictionary dictionaryWithObjects:bothUserName forKeys:bothUID];  

NSArray *sortedKeys = [dictionary keysSortedByValueUsingSelector:@selector(compare:)];

for (NSString *key in sortedKeys) {
  NSLog(@"%@: %@", key, [dictionary objectForKey:key]);
}
