Long to nsdate in Objective C

I have an char arr开发者_Python百科ay of 8 bytes which contains current date in long int. How can I convert this into NSDate.

[NSDate date]

will return the current date.

alternatively, see NSDateFormatter to convert it to a string using format specification and back. beyond that... we'll need to know the internal representation of your char array.

NSDate offers initWithTimeIntervalSinceReferenceDate. The trick is to get the 'reference date' correct. By default, Apple uses 1 January 2001.

If you have something like this=> 20100914

char arr[] = {'2','0','1','0','0','9','1','4','\0'};

NSString *dateString = [NSString stringWithCString:arr encoding:NSASCIIStringEncoding];
NSDateFormatter *df = [NSDateFormatter new];
[df setDateFormat:@"yyyyMMdd"];
NSDate *date = [df dateFromString:dateString];
