NSDateFormatter producing (null) SQLite and iOS 5.1

Question

Maybe somebody can help explain why I am getting a null value when converting a string to a date. It all looks right but I\'m obviously missing something here.

Answer 1

I changed your date format to HH not hh and it works. Here is my test code....

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];  // SQLite default date format


// test SQLite as String
NSString *testDate = @"2012-04-23 18:20:51";



NSDate *aDate = [formatter dateFromString:testDate];

NSLog(@"Using formmater on string date results in: %@", aDate);

Answer 2

NSDateFormatter uses the format patterns from the Unicode Technical Standard #35.

For the hour format, you need HH (Hour [0-23]) not hh (Hour [1-12]).
