how to get the indexpath of selected Action sheet picker Swift - json

Question

I have got myself into confusion.I need someone to help me.
I have been trying to use Action sheet picker and everything was good but I need to get the selected item. How can I do it?
ActionSheetMultipleStringPicker.show(withTitle: "Select Country", rows: [
countriesArray,], initialSelection: [0],
doneBlock: {
picker, indexes, values in
print("values = \(values)")
print("indexes = \(indexes)")
print("picker = \(picker)")
DispatchQueue.main.async {
// Update UI
self.performSegue(withIdentifier: "pdfsegue", sender: nil)
}
return
}, cancel:
{
ActionMultipleStringCancelBlock in return
}, origin: sender)
these are my arrays:
var emiratesArray = [String]()
var emiratesIdArray = [Int]()
I am getting values into my arrays from JSON:
let url = NSURL(string: EMIRATES_URL)
URLSession.shared.dataTask(with: (url as?URL)!, completionHandler: {(data,response,error) ->
Void in
if let jsonObj = try? JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? NSDictionary
{
print(jsonObj.value(forKey: "data")!)
if let messageArray = jsonObj.value(forKey: "data") as? NSArray
{
for message in messageArray
{
if let messageDict = message as? NSDictionary
{
if let data = data {
let successmessage = jsonObj.value(forKey: "success") as? Int
if(successmessage == 1)
{
if let emirate_name = messageDict.value(forKey: "emirate_name")
{
self.emiratesArray.append(emirate_name as! String)
print(emirate_name)
}
if let company_id = messageDict.value(forKey: "id")
{
self.emiratesIdArray.append(company_id as! Int)
print(company_id)
}
} else
{
}
}
}
}
}
}
}).resume()

I didn't found any Custom Class in your given code. You can create a class like below:
class Emirate: NSObject {
var id: Int
var name: String
init(id: Int, name: String) {
self.id = id
self.name = name
}
override var description: String {
return self.name
}
}
I have override the description property because ActionSheetMultipleStringPicker shows description of object given in the array if it is not String.
Declare your Emirate array
var emiratesArray = [Emirate]()
Your API request and Parsing should be like this:
let url = NSURL(string: "EMIRATES_URL")
URLSession.shared.dataTask(with: (url as?URL)!, completionHandler: {(data,response,error) ->
Void in
if let jsonObj = try? JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? NSDictionary
{
print(jsonObj.value(forKey: "data")!)
if let messageArray = jsonObj.value(forKey: "data") as? NSArray
{
for message in messageArray
{
if let messageDict = message as? NSDictionary
{
if let data = data {
let successmessage = jsonObj.value(forKey: "success") as? Int
if(successmessage == 1)
{
if let emirate_name = messageDict.value(forKey: "emirate_name") as? String, let company_id = messageDict.value(forKey: "id") as? Int
{
self.emiratesArray.append(Emirate(id: company_id, name: emirate_name))
print(emirate_name)
}
} else
{
}
}
}
}
}
}
}).resume()
Now feed your action sheet self.emiratesArray
ActionSheetMultipleStringPicker.show(withTitle: "Select Country", rows: [
self.emiratesArray], initialSelection: [0],
doneBlock: {
picker, indexes, values in
print("values = \(values)")
print("indexes = \(indexes)")
print("picker = \(picker)")
DispatchQueue.main.async {
// Update UI
self.performSegue(withIdentifier: "pdfsegue", sender: nil)
}
return
}, cancel:
{
ActionMultipleStringCancelBlock in return
}, origin: sender)
You will now get the selected Emirate class objects in values array.
N.B- This code is just to give you an idea about how it can work.
