NSDate in string shows date of one month before

I am taking date of string having format yyyy-MM-DD from database then converting it into NSDate having format yyyy-MM-DD. And again converting back it into string format dd-MM.

But when at last I get date in string format it shows one month before date.

Here is the code I have used:

   NSDateFormatter *format=[[NSDateFormatter alloc]init];
   NSDateFormatter *format2=[[NSDateFormatter alloc]init];

   NSString *date;
   [format setDateFormat:@"yyyy-MM-DD"];
   [format2 setDateFormat:@"DD-MMM"];

   dict=[[NSMutableDictionary alloc]init];

   for(int i=0;i<[viewHistoryData count];i++)
   {
       dict=[viewHistoryData objectAtIndex:i];


           date=[dict objectForKey:@"Date"];

       NSLog(@"My date with out format = %@",date);
       NSString *dateString =[format2 stringFromDate:[format dateFromString:date]];
       NSLog(@"My date is = %@",dateString);


       [tempArray addObject:dateString];  
   }

OUTPUT

2014-02-07 15:01:07.586 VirtualRunner-V3[3580:c07] My date with out format = 2014-02-07
2014-02-07 15:01:07.588 VirtualRunner-V3[3580:c07] My date is = 07-Jan

Does anybody know how to solve this?

Correct the two format. 

[format setDateFormat:@"yyyy-MM-dd"];
[format2 setDateFormat:@"dd-MMM"];

But I think, Issue related with timezone. Use below to format.

[format2 setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"GMT+0:00"]];

The format DD representes day of the year, not day of the month, so change your formatters to this:

 [format setDateFormat:@"yyyy-MM-dd"];
 [format2 setDateFormat:@"dd-MMM"];

You are using the wrong placehodler for day of month. What you are using is Day of Year ranging from 1 ... 365. So instead of

[format setDateFormat:@"yyyy-MM-DD"];

use

[format setDateFormat:@"yyyy-MM-dd"];

See this link for a complete overview.
