I want know the passed time that also is between two date,
for example , dateTime1
and dateTime2
, I want a function like getPassedTime( time1, time2)
The function result should be like 1 day 3 hours 12 minutes 10 second
or just 40 second
.
I know that the method timeIntervalSinceDate
of the class NSDate
can be use, but the problem is convert to details string that could be easy understand.
Anyone can help? share some code will be appreciate or give me some tip if possible.
