Sorting NSArray of dictionaries by value of a key in the dictionaries

We Got The Solution By Using The Method Follows

[self.jsonData sortUsingDescriptors: [NSArray arrayWithObjects: [NSSortDescriptor sortDescriptorWithKey:"fullname" ascending:YES], [NSSortDescriptor sortDescriptorWithKey:"id" ascending:NO], nil]];

Where:-

jsonData - MutableArray Which holds the Parsed JSON Data.

fullname - the data we want to sort.

id - An unique data which comes with the inner dictionary.

I think this will do it:

brandDescriptor = [[NSSortDescriptor alloc] initWithKey:@"brand" ascending:YES];
sortDescriptors = [NSArray arrayWithObject:brandDescriptor];
sortedArray = [myArray sortedArrayUsingDescriptors:sortDescriptors];

I pulled the code from Sort Descriptor Programming Topics. Also, Key-Value Coding comes into play, in that sortedArrayUsingDescriptors: will send a valueForKey: to each element in myArray, and then use standard comparators to sort the returned values.
