Get Specific Objects Inside An Array of Dictionaries in Objective-C -

I have an array of dictionaries and I want to get the value of that array in which the key is searching. / P>

For example, I have named this array as locationArray :

  ({id = 1, info = {name = "Person1 "Address =" Chicago ";}}}} ID = 2, info = {name =" person2 "; address =" Chicago "}}}} id = 3, info = {name =" person3 "; address = " New York "; };};);   
 And I want to get an array of people with a street address in Chicago. The result will be as follows ( chicagoArray ):  
  ({id = 1, info = {name = "Person1"; address = "Chicago";};}; Id = 2, info = {name = "person2"; address = "Chicago";};};);   
 I have looped this but I do not know what has been made of my result: Error:  
 for  (id result in locationArray) {if ([[Result Value ForKeyPath @ "info.address"] is EqualToString: @ "Chicago"]) // // What is the result inside of Array? // NSArray * resultArray = [[NSArray alloc] initWithObjects: @ ""]; }}   
 How can I do this? Thanks!   
 
 
  NSMutableArray * entries = [NSMutableArray array]; For (NSDictionary * dict in the array) {NSDictionary * innerDict = dict [@ "info"]; If ([Internal [["" address "] is avatostring: @" Chicago "]) [[Add entries: word];}}
