How to get first date of month?

Question

I am working on get start and end date from today's date.

I am getting start and end date of current month by using formula given by Martin R

Get first and last day of month

It is working perfectly.

My issue is how to put my custom value in this line

let components1 = calendar.components([.Year, .Month], fromDate: date)

Can I replace my custom month value to this code?

My requirement is:

I have one tableView for months like January, etc. When I will click TableView I am getting current month according to tableview.

Suppose I click on January, I will get value 1.

So how to get start and end date of month using my custom month value?

My Code

 let date = NSDate()
        let calendar   = NSCalendar.currentCalendar()
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "dd MM yyyy"

        //To Get Start Date of Month
        let components1  = calendar.components([.Year,.Day], fromDate: date)
        components1.month = 3
        let startOfMonth = calendar.dateFromComponents(components1)!
        txtStartDate.text = dateFormatter.stringFromDate(startOfMonth)

Answer 1

try this code:

    let calendar = NSCalendar.currentCalendar()
    let date = "January 2016" // custom value
    let dateFormatter = NSDateFormatter()
    dateFormatter.dateFormat = "MMMM yyyy"

    let components = calendar.components([.Year, .Month, .Day], fromDate: dateFormatter.dateFromString(date)!)
    let startOfMonth = calendar.dateFromComponents(components)!
    dateFormatter.dateFormat = "MM"
    print(dateFormatter.stringFromDate(startOfMonth))
    //NSLog("%@ : %@", startOfMonth,dateFormatter.stringFromDate(startOfMonth));

Output:

01

plz go through this solution to get start and end date from custom values thanks @Martin R

let calendar   = NSCalendar.currentCalendar()

        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "dd MM yyyy"

        //To Get Start Date of Month
        let components1 = calendar.components([.Year], fromDate: NSDate())
        components1.month = Int(tempNumber!)!
        let startOfMonth = calendar.dateFromComponents(components1)!
        txtStartDate.text = dateFormatter.stringFromDate(startOfMonth)

        //To Get End Date of Month
        let comps2 = NSDateComponents()
        comps2.month =  1
        comps2.day   = -1
        let endOfMonth = calendar.dateByAddingComponents(comps2, toDate: startOfMonth, options: [])!
        txtEndDate.text = dateFormatter.stringFromDate(endOfMonth)
