how to change order of NSMutable array in same way another mutable arrays get changed

Question

I have three arrays. They are name, birthdates and remaining days like below:

    name                         birth         


        

Answer 1

Put each row into a dictionary, and out those dictionaries into an array. Then sort your away using a predicate or sort block. If you want an array containing just the sorted names for example, you could use [ array valueForKeyPath:@"name" ]

Array looks like:

[
    { @"name" : ..., 
        @"birthdate" : ...birthdate..., 
        @"remaining" : ...days remaining... } ,
    {...},
    {...}
]
