https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSDate_Class/index.html#//apple_ref/occ/clm/NSDate/dateWithNaturalLanguageString:
Creates and returns an NSDate object set to the date and time specified by a given string.
Declaration
Swift
class func dateWithNaturalLanguageString(_ string: String) -> AnyObject?
Objective-C
+ (id)dateWithNaturalLanguageString:(NSString *)string
Parameters
string
A string that contains a colloquial specification of a date, such as
“last Tuesday at dinner,” “3pm December 31, 2001,” “12/31/01,” or
“31/12/01.”
Return Value
A new NSDate object set to the current date and time specified by string.
Discussion
This method supports only a limited set of colloquial phrases,
primarily in English. It may give unexpected results, and its use is
strongly discouraged. To create a date object from a string, you should
use a date formatter object instead (see NSDateFormatter and Data Formatting Guide).
In parsing the string, this method uses the date and time preferences stored in the user’s defaults database. (See dateWithNaturalLanguageString:locale: for a list of the specific items used.)
Import Statement
import Foundation
Availability
Available in OS X v10.4 and later.
Deprecated in OS X v10.10.

[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSDate *date = [dateFormatter dateFromString:@"2010-08-04 16:01:03"];
NSLog(@"%@", date);
[dateFormatter release];
使用NSDate和NSString相互转换
