Answer 1

you can format your string using dd / MM / yyyy hh: mm: ss a

example below:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd/MM/yyyy hh:mm:ss a"];
NSLog(@"%@", [dateFormatter dateFromString:@"12/12/2012 12:12:12 AM"]);

Answer 4

You can use the following method, just pass the date to it:

-(NSString *)getDateFromString:(NSString *)string
{

    NSString * dateString = [NSString stringWithFormat: @"%@",string];

    NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"your current date format"];
    NSDate* myDate = [dateFormatter dateFromString:dateString];

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"your desired format"];
    NSString *stringFromDate = [formatter stringFromDate:myDate];

    NSLog(@"%@", stringFromDate);
    return stringFromDate;
}
