Question

这个问题与我以前的帐户问题有关。

How to make API call for this web service to fetch array of present and absent dates separately in swift?

码

import UIKit
import FSCalendar

class AttendenceViewController : UIViewController, FSCalendarDelegate, FSCalendarDataSource, FSCalendarDelegateAppearance
{

@IBOutlet weak var calendar: FSCalendar!

var presentdays : Array = [String]()
var absentdays : Array = [String]()
fileprivate let gregorian: Calendar = Calendar(identifier: .gregorian)
fileprivate lazy var dateFormatter1: DateFormatter = {
    let formatter = DateFormatter()
    formatter.dateFormat = "yyyy-MM-dd"
    return formatter
}()
fileprivate lazy var dateFormatter2: DateFormatter = {
    let formatter2 = DateFormatter()
    formatter2.dateFormat = "dd"
    return formatter2
}()

    override func viewDidLoad() {
    super.viewDidLoad()
        self.getdateFromJSON()


}



func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, fillDefaultColorFor date: Date) -> UIColor? {
    let datestring2 : String = dateFormatter1.string(from: date)
    if presentdays.contains(datestring2)
    {
        return UIColor.green
    }
    else if absentdays.contains(datestring2)
    {
        return UIColor.red
    }
    else
    {
        return nil
    }

}
func getdateFromJSON()
{
    let url = NSURL(string: "ezschoolportalapi.azurewebsites.net/api/Student/AttendanceDetails?schoolid=1&studentid=2&month=6&year=2017")
    let request = NSMutableURLRequest(url: url! as URL)
    let task = URLSession.shared.dataTask(with: request as URLRequest) { (data, response, error)
        in
        guard error == nil && data != nil else
        {
            print("Error:",error)
            return
        }
        let httpstatus = response as? HTTPURLResponse
        if httpstatus?.statusCode == 200
        {
            if data?.count != 0
            {
                if let responseJSON = (try? JSONSerialization.jsonObject(with: data!, options: .allowFragments)) as? [String:Any],
                    let presentdetails = responseJSON["Present"] as? [[String:Any]],
                    let Absentdetails = responseJSON["Absent"] as? [[String:Any]] {

                    let dateFormatter = DateFormatter()
                    dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"


                    self.presentdays = presentdetails.flatMap { dateFormatter.date(from: $0["Date"] as! String) }.flatMap {
                        self.dateFormatter2.string(from:$0)
                    }
                    self.absentdays = Absentdetails.flatMap { dateFormatter.date(from: $0["Date"] as! String) }.flatMap { self.dateFormatter2.string(from:$0) }
                    DispatchQueue.main.async
                        {
                    self.calendar.reloadData()
                    }
                }
                }

            else
            {
                print("No data got from URL")
            }
        }
        else{
            print("error httpstatus code is :",httpstatus?.statusCode)
        }

    }
    task.resume()

}

 }

将函数getdateFromJSON()替换为

func getdateFromJSON()
        {
            let url = NSURL(string: "http://ezschoolportalapi.azurewebsites.net/api/Student/AttendanceDetails?schoolid=1&studentid=2&month=6&year=2017")
            let request = NSMutableURLRequest(url: url! as URL)
            let task = URLSession.shared.dataTask(with: request as URLRequest) { (data, response, error)
                in
                guard error == nil && data != nil else
                {
                    print("Error:",error ?? "error")
                    return
                }
                let httpstatus = response as? HTTPURLResponse
                if httpstatus?.statusCode == 200
                {
                    if data?.count != 0
                    {
                        if let responseJSON = (try? JSONSerialization.jsonObject(with: data!, options: .allowFragments)) as? [String:Any],
                            let presentdetails = responseJSON["Present"] as? [[String:Any]],
                            let Absentdetails = responseJSON["Absent"] as? [[String:Any]] {

                            let dateFormatter = DateFormatter()
                            dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"


                            self.presentdays = presentdetails.flatMap { dateFormatter.date(from: $0["Date"] as! String) }.flatMap {
                                self.dateFormatter1.string(from:$0)
                            }
                            self.absentdays = Absentdetails.flatMap { dateFormatter.date(from: $0["Date"] as! String) }.flatMap { self.dateFormatter1.string(from:$0) }
                            DispatchQueue.main.async
                                {
                                    self.calendar.reloadData()
                            }
                        }
                    }
                    else
                    {
                        print("No data got from URL")
                    }
                }
                else{
                    print("error httpstatus code is :",httpstatus?.statusCode ?? "5")
                }

            }
            task.resume()
        }
