date - iOS 时间计算，月数间隔

Question

iOS开发中如何获取某三个月之间的秒数，主要现在有个需求，要得到个时间间隔，要求起始时间为现在的时间点，终止时间为某些月后的这个时间点。有没有什么方法，难道必须要做判断吗，什么闰月之类的！！！

iOS是否有原生的方法啊？T__T

Answer 1

There is no native method from Apple to get this time point after a certain month. There is an open source library on Github that helps with date calculation

Answer 3

I would like to recommend you a commonly used time processing library in open source libraries - DateTools, which can accomplish almost everything you want.
If you are interested, you can refer to how it is implemented.
