DispatchQueue.main.async

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

推荐答案
将功能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()
}
