Sort a dictionary array when the key is given as the parameter

Question

I'm working in a project in swift3 and I have an NSArray named "details" that contains NSDictionary Objects. My requirement is to sort this NSArray If a "key" is passed as the parameter (eg:- name, lastName, age). My NSArray looks like bellow.

(
 {name:"John";
  lastName :"bow";
  age: "26"; 
 },
 {
  name:"paul";
  lastName :"law";
  age: "19";
  }

)

how can I achieve this ??

Answer 1

Try this :

NSSortDescriptor * sortDescriptors = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; // change your key here
NSArray * arrSortDescriptors = [NSArray arrayWithObject:sortDescriptor];
NSArray * sortedArray = [yourArray sortedArrayUsingDescriptors:arrSortDescriptors];
NSLog(@"sortedArray %@",sortedArray);
