Converting string to date and get date string

In my app I have a string 'date'="2015-03-16".

I need to show it in a label as Lunes 16 de marzo 2015 (Monday 16 March 2015). I am using the following code to do it:

   NSString *dateStr = date;

    // Convertimos el string date a objeto de fecha
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"yyyy-MM-d"];
    NSDate *fecha = [dateFormat dateFromString:dateStr];
    NSLog(@"DATE CONVERTIDO A FECHA =%@", fecha);

    NSDateFormatter *df = [[NSDateFormatter alloc] init];

    [df setDateFormat:@"EEEE, dd MMM yyyy"];


    fecha = [df dateFromString: date];

    NSLog(@"date: %@", fecha);

But at the end I get (null) for the variable 'fecha' Log --> date: (null)

What am I doing wrong?

You were using format @"yyyy-MM-d", Use @"yyyy-MM-dd"

NSString *dateStr = date;

// Convertimos el string date a objeto de fecha
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd"];//You were using only d
dateFormat.dateStyle = NSDateFormatterFullStyle
NSDate *fecha = [dateFormat dateFromString:dateStr];

NSLog(@"DATE CONVERTIDO A FECHA =%@", fecha);

NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"EEEE, dd MMM yyyy"];
NSString *newDatestr = [df stringFromDate:fecha];
NSLog(@"date: %@", newDatestr);

You are going in opposite direction after your df formatter replace your code with this:

NSString *dateStr=@"2015-03-16";
// Convertimos el string date a objeto de fecha
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd"];
NSDate *fecha = [dateFormat dateFromString:dateStr];
NSLog(@"DATE CONVERTIDO A FECHA =%@", fecha);

NSDateFormatter *df = [[NSDateFormatter alloc] init];

[df setDateFormat:@"EEEE, dd MMM yyyy"];


NSString *newDatestr = [df stringFromDate:fecha];

NSLog(@"date: %@", newDatestr);

Hope it helps...........:)

Your df formatter code is doing another dateFromString And I think you intended to go the other direction for this second formatter (e.g. stringFromDate of the fecha previously determined).
