Get three letter month and day from string date?

Question

I have string date such like,

NSString * dateStr = @"2014-12-31";

I want to get month in three letter month such like Des (from dateStr) and day such like 31

I tried about 2 hour but i can't get it properly..

My code is..

First convert string to date ;

NSString *dateStr = [[self.listOfEvents objectAtIndex:indexPath.row] objectForKey:@"EventDate"];
NSDateFormatter *DTFormatter = [[NSDateFormatter alloc] init];
[DTFormatter setDateFormat:@"yyyy-MM-dd"];
NSDate *eventDate = [DTFormatter dateFromString:dateStr];
NSLog(@"eventDate - %@", eventDate);

And now convert date to string;

NSDateFormatter *currentDTFormatter = [[NSDateFormatter alloc] init];
[currentDTFormatter setDateFormat:@"dd MMM"];
NSString *eventDateStr = [DTFormatter stringFromDate:eventDate];
NSLog(@"eventDateStr - %@", eventDateStr);

So, please suggest me where i was wrong here.

EDITED :

I got console output is

eventDate - 2014-12-31 18:30:00 +0000
eventDateStr - 2014-12-31

Answer 1

The problem is you are converting using old dateformatter that is DTFormatter you have to use currentDTFormatter in place of it.

Try with currentDTFormatter this formatter.

NSDateFormatter *currentDTFormatter = [[NSDateFormatter alloc] init];
[currentDTFormatter setDateFormat:@"dd MMM"];
NSString *eventDateStr = [currentDTFormatter stringFromDate:eventDate];
NSLog(@"%@", eventDateStr);

Answer 2

Try adding this line [currentDTFormatter setDateStyle:NSDateFormatterMediumStyle]; before you are calling setDateFormat

Here is the appropriate passage from apple's documentation:

    NSDateFormatterMediumStyle

    Specifies a medium style, typically with abbreviated text, such as “Nov 23, 1937”.

    Equal to kCFDateFormatterMediumStyle.

    Available in OS X v10.4 and later.

    Declared in NSDateFormatter.h.

这也是在这里说https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/DataFormatting/Articles/dfDateFormatting10_4.html#//apple_ref/doc/uid/TP40002369-SW1仅使用一个“ d”因此，“ EdMMM”应该适用于英语语言环境，或者我猜“ dMMM”甚至是“ d MMM”

Answer 4

Have you tried:

[formatter setDateFormat:@"dd-MMM-YYYY HH:mm"]; 

and then

[formatter stringFromDate:someNSDate];

Answer 5

Here is the Solution

NSString * dateStr = @"2014-12-31";
NSDateFormatter* df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"yyyy-MM-dd"];
NSDate* date = [df dateFromString:dateStr];
NSLog(@"%@", date);
[df setDateFormat:@"dd MMM"];
NSString *dateString = [df stringFromDate:date];
NSLog(@"%@", dateString);

Answer 6

Please try to use the below code to convert your date string...

- (NSString*) formatDateString:(NSString*)date
{
NSDateFormatter *inputFormatter = [[NSDateFormatter alloc] init];
[inputFormatter setDateFormat:@"yyyy-MM-dd"];

NSDate *formattedDate = [inputFormatter dateFromString: date];
NSDateFormatter *outputFormatter = [[NSDateFormatter alloc] init];
[outputFormatter setDateFormat:@"dd MMM"];

NSString *displayDate = [NSString stringWithFormat:@"%@", [outputFormatter stringFromDate:formattedDate]];

return displayDate;

}

And also you can set format styles to NSDateFormatter for formatting your date string

setTimeStyle:  

setDateStyle:

You can check NSDateFormatter for your reference from below link.
