将NSString转换为NSDate不起作用

Question

I've read the DateFormatting guide and I'm still not able to get why my date conversion is not working as per requirement. For example:

NSString *str1 = @"12/20/2013 12:39:55 PM";
NSDateFormatter *dateFo = [[NSDateFormatter alloc] init];

[dateFo setDateFormat:@"MM/dd/YYYY hh:mm:ss a"];
NSDate *serverDate1 = [NSDate date];
serverDate1 = [dateFo dateFromString:str1];

In return I'm getting date as " 2013-01-05 07:09:55 +0000 ". I have tried a lot why NSDate is not returning correct date.

Any help would be appreciated.

Answer 1

Instead of YYYY use yyyy in your dateFormat: .

NSString *str1 = @"12/20/2013 12:39:55 PM";
NSDateFormatter *dateFo = [[NSDateFormatter alloc] init];

[dateFo setDateFormat:@"MM/dd/yyyy hh:mm:ss a"];
NSDate *serverDate1 = [NSDate date];
serverDate1 = [dateFo dateFromString:str1];

Answer 2

NSString *dateWithInitialFormat = @"12/20/2013 12:39:55 PM";
NSDateFormatter *dateFo = [[NSDateFormatter alloc] init];
[dateFo setDateFormat:@"MM/dd/yyyy hh:mm:ss a"];
NSDate *serverDate1 = [NSDate date];
serverDate1 = [dateFo dateFromString:dateWithInitialFormat];

This will get you your solution
