问题描述
我以前的问题是仅使用2个当前和不存在的天数数组在FSCalendar上显示静态数据.
it was my previous question to simply display static data on FSCalendar using 2 arrays of present and absent days.
如何更改背景色的FSCalendar swift 3中的事件数组?
现在，我想以2array的格式从以下json响应中获取当前日期和缺席日期:根据我先前的问题，现在要在FSCalendar上显示.
now I want to fetch the present and absent dates from the following json response in the format of 2array named : present and absent want to display on FSCalendar according to my previous question.
如何解析相同的内容?请指导我.预先感谢.

func getdateFromJSON()

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
{
let responseString = try! JSONSerialization.jsonObject(with: data!, options: .allowFragments) as! NSDictionary
let presentdetails = responseString["Present"] as? [[String:AnyObject]]
let absentdetails = responseString["Absent"] as? [[String:AnyObject]]
print(absentdetails)
print(presentdetails)
// dont know what to do next :(
}
else
{
print("No data got from URL")
}
}
else{
print("error httpstatus code is :",httpstatus?.statusCode)

}
task.resume()

推荐答案
在Swift中不要使用NSDictionary，您只需要使用DateFormatter即可获取格式化日期.同样在Swift 3中正确的JSON词典是[String:Any].
Don't use NSDictionary in Swift, you just need to use DateFormatter to get your formatted date. Also correct JSON dictionary in Swift 3 is [String:Any].
首先在类型为presentDateArray和absentDateArray的类[String]中声明两个实例属性.
First of all declare two instance property in your class of type [String] named presentDateArray and absentDateArray.
var presentDateArray = [String]()
var absentDateArray = [String]()
现在以这种方式在响应完成块中初始化这两个数组.
Now initialize these two array in your response completion block this way.
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.presentDateArray = presentdetails.flatMap { dateFormatter.date(for: $0["Date"] as! String) }.flatMap { dateFormatter1.string(from:$0) }
self.absentDateArray = Absentdetails.flatMap { dateFormatter.date(for: $0["Date"] as! String) }.flatMap { dateFormatter1.string(from:$0) }
DispatchQueue.main.async {
calendar.reloadData()
}
}
现在简单地在
func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, titleDefaultColorFor date: Date) -> UIColor? {
let datestring2 : String = dateFormatter1.string(from:date)
if presentDateArray.contains(datestring2) {
return UIColor.green
}
else if presentDateArray.contains(datestring2) {
return UIColor.red
}
else {
return nil
}
}
