How does one sort an array of objects by accessing their NSDate properties?

我知道一个人可以在日期数组上使用[mutableArray sortUsingSelector:@selector(compare:)];，但是如何通过访问数组中每个元素的NSDate属性并按最早日期到最新日期对对象进行排序呢?

I know one can use [mutableArray sortUsingSelector:@selector(compare:)]; on an array of dates, but how does one do it by accessing a NSDate property on each element in the array, sorting the objects by earliest date to latest date?
