Need to sort an NSArray in a jiffy? Not to worry! There’s an app—err, method
for that! Using NSMutableArray’s built-in sortUsingDescriptors method,
sorting is a snap!
Here’s an example from an app I’m working on now:
[tempChampList sortUsingDescriptors:@[
[NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES]
]];
Things to keep in mind:
- This is a method of
NSMutableArray, that’s NS—Mutable—Array. - This method requires an NSArray of descriptors
- You must construct the
NSSortDescriptorobjects—how else would we know how to sort? - Descriptors could be properties of your objects. In my case, the
NSMutableArray contains a list of objects that all have a
nameproperty.
