Question

I have an array of dictionaries..looks like this.

(
   {name = somename;
    date = NSDate;
    other_params = some other params;
   },
   ...
)

How can I then sort the array items by NSDate (oldest to newest or vice versa). Do I just do a basic select-sort algorithm or is there a shorter way?

Answer 1

You can sort the array using descriptors or using comparators, whatever you feel more comfortable with. Here is an example of using comparators:

NSArray *sortedArray = [myArray sortedArrayUsingComparator: ^(id obj1, id obj2) {
    return [[obj1 date] compare:[obj2 date]];
}];
