For a simple sort like this, I like to use sort descriptors.

Suppose you have an mutable array of objects whose class has a name NSString property:

NSSortDescriptor *sort=[NSSortDescriptor sortDescriptorWithKey:@"name" ascending:NO];
[myArray sortUsingDescriptors:[NSArray arrayWithObject:sort]];

This will start with "W" and not with "A". How to start with "A"? –  Jonathan Developer Aug 16 at 20:20

Absolutely, you can use sortUsingSelector: for this:

[myArray sortUsingSelector:@selector(compare:)];

If your array has custom objects, then you will need to implement a sorting method on those objects:

@implementation myCustomObject
  ...

  -(NSComparisonResult) compare:(myCustomObject*) other {
      return [self.name compare:other.name];
  }

@end

nice one line answer (for simple arrays). –  newenglander Jun 2 '12 at 10:48

TechZen's approach works well, but it would work better if you used NSSortDescriptor's +sortDescriptorWithKey:ascending:selector:, passing "localizedCompare:" as the selector. This way, the sorting is localized to the user's language, which can make a big difference in string comparison.

myArray=[myDict keysSortedByValueUsingSelector:@selector(compare:)];

Simply Worked for me!
