I'd like to vote for closing this question as a duplicate. But there are so many duplicates that I can't decide which one to select. So please be more specific and provide details on what you've already tried and why it didn't work. — tilo, Oct 28 '13 at 11:03
This is simply duplicate of `NSDateFormatter` there is no need for any complex and extra calculation @tilo — TheTiger, Oct 28 '13 at 11:04
@TheTiger this was more of a "you said you've gone through so many answers .. go on and you'll find the one that fits your specific problem." — tilo, Oct 28 '13 at 11:06
@tilo Actually I'm unable to find any issue here. If anybody knows use of `NSDateFormatter` its very simple. And I'm sure 2-3 minutes R&D on google can solve this easily. — TheTiger, Oct 28 '13 at 11:09

Apply this code changing the manually coded time and date with your properties and It should work.

NSDateFormatter * dateFormatter = [[NSDateFormatter alloc]init];
[dateFormatter setDateFormat:@"yyyy-MM-dd"];
NSDate * dateNotFormatted = [dateFormatter dateFromString:@"2013-10-29"];
[dateFormatter setDateFormat:@"d MMM.YYYY"];    
NSString * dateFormatted = [dateFormatter stringFromDate:dateNotFormatter];

[dateFormatter setDateFormat:@"HH:mm"];
NSDate * timeNotFormatted = [dateFormatter dateFromString:@"11:30"];
[dateFormatter setDateFormat:@"hh:mm a"];    
NSString * timeFormatted = [dateFormatter stringFromDate:timeNotFormatter];

The other option is put tighter time and date in one string and use this format:

    [dateFormatter setDateFormat:@"d MMM.YYYY at hh:mm a"];

Use NSDateFormatter. In first case your format will be: @"yyyy-MM-dd", @"HH:mm", and in the second one: @"dd MMM.yyyy", @"hh:mm a"

NSDateFormatter *formatter=[[NSDateFormatter alloc]init]; [formatter setDateFormat:@"dd MMM.YYYY "]; NSDate *date=[[NSDate alloc]init]; date=[formatter dateFromString:@"2013-10-29"]; and here date is returning "null" – Srinivasa Reddy Oct 28 '13 at 11:02

First of combine date & Time like "2013-10-29 11:30"

than use the below function like [self dateFormat:@"yyyy-NN-dd HH:ss" newFormat:@"dd MMM.yyyy hh:mm a"]

- (NSString*) dateFormat : (NSString*)date currentFormat:(NSString*) currentFormat newFormat : (NSString*) newFormat
{
    NSString *dateStr = date;
    NSDateFormatter *dtF = [[NSDateFormatter alloc] init];
    [dtF setDateFormat:currentFormat];
    NSDate *d = [dtF dateFromString:dateStr];

    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:newFormat];
    NSString * strFinalDate = [dateFormat stringFromDate:d];
    NSLog(@"%@",strFinalDate);

    [dtF release];
    [dateFormat release];

    return strFinalDate;
}

if you want Date and Time differ than separate it using NSArray.
