NSDateFormatter dateFromString return null

I want to get NSDate from NSString. My code:

NSDateFormatter *dateFormatter = [NSDateFormatter new];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSDate *date = [dateFormatter dateFromString:@"2016-05-05 09:29:31"];
NSLog(@"date %@",date);

And I see in console:

date (null)

What is wrong with my date format? Thank you.

Your code is correct. 

If the device is set to AM/PM time and requested string format is set to @"yyyy-MM-dd HH:mm:ss" dateFromString will return nil. Try setting the locale like :

[dateFormatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]];

You can also use my code for getting NSDate from NSString for any kind of format you want.

Below is my code :

- (NSDate *)dateFromString:(NSString *)stringDate withFormat:(NSString *)format {
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

    formatter.dateFormat = format;

    NSDate *dateFromString = [formatter dateFromString:stringDate];

    return dateFromString; }

try this code

NSString *dateString = @"05-05-2016 09:29:31";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

// if format doesn't match you'll get nil from your string, so be careful

[dateFormatter setDateFormat:@"dd-MM-yyyy HH:mm:ss"];
NSDate *dateFromString = [[NSDate alloc] init];

dateFromString = [dateFormatter dateFromString:dateString];

Use below code ..

[dateFormatter setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
NSString *date_time  =  [dateFormatter stringFromDate:[NSDate date]];

Hope this is useful
