How to add hours to an NSDate?
问题 I have a date converted to double value and saved in database. Now, I want to compare if currentDate > myDataBaseDate + 8 hours i.e., I want to get 8 hours added to myDataBaseDate. I'm converting date into double values. So how do I get 8 hours later time from my database saved date. How do I compare if (currentDateTime > DateFromdatabaseValue + DateByAdding8HoursInDataBase) 回答1: I'm not entirely sure what you are trying to do, but you can create an NSDate object by adding time in seconds on
