How to get the time in iOS Programming

Question

I wanted to get random numbers according to time. How do you get the current time in iOS Programming for the iPhone?

Answer 1

NSDate *now = [[NSDate alloc] init]; OR NSDate *now = [NSDate date];
an NSDate object by default will be initialised to the current date.

Answer 2

in addition to the existing answers:

gettimeofday for high accuracy

or

CFAbsoluteTimeGetCurrent if you want a fairly high level interface without an object.
