How to get all months of a year in particular format

Question

How can i get all the months of a year in a table view in this particular format "January 2013" and so on. I need to set the starting month also. Below is the code i tried.

int mCurrentMonth = [dateComponents month];
int mCurrentYear = [dateComponents year];

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

NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"MM"];
NSDate* myDate = [dateFormatter dateFromString:dateString];

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"MMMM"];
NSString *stringFromDate = [formatter stringFromDate:myDate];
NSString *mon = [NSString stringWithFormat:@"%@ %d",stringFromDate, mCurrentYear];
NSLog(@"month:%@", mon);

Above code is giving me only current month in required format. Other way i tried is this

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

for (int i = 0; i < 12; i++){
    NSString *monthName = [[df monthSymbols] objectAtIndex:i];
    NSLog(@"months name:%@", monthName);
}

This way i am getting all months name but not with year. I am not getting how to achieve the desired output that is January 2013 February 2013 and so on.

Try this :

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

    NSDate           *today           = [NSDate date];
    NSCalendar       *currentCalendar = [NSCalendar currentCalendar];
    NSDateComponents *yearComponents  = [currentCalendar components:NSYearCalendarUnit  fromDate:today];
    int currentYear  = [yearComponents year];
    for(int months = 0; months < 12; months++)
        NSLog(@"%@ %i",[[dateFormatter monthSymbols]objectAtIndex: months],currentYear);

output will be :

January 2013

February 2013

March 2013

April 2013

May 2013

June 2013

July 2013

August 2013

September 2013

October 2013

November 2013

December 2013

Edited : For Above output from current month Use following code :

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

    NSDate           *today           = [NSDate date];
    NSCalendar       *currentCalendar = [NSCalendar currentCalendar];
    NSDateComponents *yearComponents  = [currentCalendar components:NSYearCalendarUnit |    NSMonthCalendarUnit  fromDate:today];
    int currentYear  = [yearComponents year];
    int currentmonth=[yearComponents month];
    NSLog(@"current Month %d",currentmonth);
    for(int months = currentmonth - 1; months < 12; months++)
        NSLog(@"%@ %i",[[dateFormatter monthSymbols]objectAtIndex: months],currentYear);

Swift 4.2

let dateFormatter = DateFormatter()
let today = Date()
let currentCalendar = Calendar.current
var yearComponents: DateComponents? = currentCalendar.dateComponents([.year], from: today)
let currentYear = Int(yearComponents!.year!)
for months in 0..<12 {
    print("\(dateFormatter.shortMonthSymbols[months]) \(currentYear)")
}

Output:

Jan 2017
Feb 2017
Mar 2017
Apr 2017
May 2017
Jun 2017
Jul 2017
Aug 2017
Sep 2017
Oct 2017
Nov 2017
Dec 2017
