Order by NSDate a NSMutableArray containing NSObjects that contain NSDates

Question

My object "Event" has got a property NSDate. I fill a NSMutableArray with "Event" objects. Is there a way to order by NSDate the members of my NSMutableArray? Thank you all.

Answer 1

Assuming you have an NSMutableArray

[yourArray sortUsingComparator:^NSComparisonResult(Event *obj1, Event *obj2){
     return [obj1.date compare:obj2.date];
}];

Otherwise :

NSArray sortedArray = [yourArray sortedArrayUsingComparator:^NSComparisonResult(Event *obj1, Event *obj2) {
    return [obj1.date compare:obj2.date];
}];
