hi i am trying to get the son response from the server and the following is the response i get from server while using postman
{
"stories": [
{
"image_url": "http://storybox.dk/wp-content/uploads/2016/11/Hansa.jpg",
"name": "New story",
"story_key": "ahJlfnN0b3J5Ym94LWJhY2tlbmRyEgsSBVN0b3J5GICAgIC8oYIKDA"
},
{
"image_url": "http://storybox.dk/wp-content/uploads/2016/11/Hansa.jpg",
"name": "Story of Foo the fox.",
"story_key": "ahJlfnN0b3J5Ym94LWJhY2tlbmRyEgsSBVN0b3J5GICAgID4woQKDA"
}]
}
but when i try to get the values inside the stories tag as array it gets only one value as
self.StoryListArr = (reponsedict.value(forKey: "stories") as? NSArray)!
(
{
"image_url" = "http://storage.googleapis.com/storybox-backend.appspot.com/5649391675244544/Screenshot_from_2017-03-16_113338.png";
name = "Story of Foo";
"story_key" = ahJlfnN0b3J5Ym94LWJhY2tlbmRyEgsSBVN0b3J5GICAgID4woQKDA;
}
)
please advice how to deal this
when i try to print response dict it shows only one value in it
{
stories = (
{
"image_url" = "http://storage.googleapis.com/storybox-backend.appspot.com/5649391675244544/Screenshot_from_2017-03-16_113338.png";
name = "Story of Foo";
"story_key" = ahJlfnN0b3J5Ym94LWJhY2tlbmRyEgsSBVN0b3J5GICAgID4woQKDA;
}
);
}
There is no reason to use NSArray in Swift. Simply cast the object to [Dictionary].
if let stories = responsedict["stories"] as? [Dictionary<String,String>] {
print(stories)
}

I have a large JSON response and inside
{
"availabilityResultList": [
{
"availabilityRouteList": [
{
"availabilityByDateList": [
{
"originDestinationOptionList": [
there are 3 separate
"originDestinationOptionList": [
{
"fareComponentGroupList":[...]
},
{
"fareComponentGroupList":[...]
},
{
"fareComponentGroupList":[...]
},
],
I can access the values in the first 'fareComponentGroupList' with Codables
as
root.availabilityResultList.first?.availabilityRouteList.first?.availabilityByDateList.first?.originDestinationOptionList.first?.fareComponentGroupList.first?.xxx
How do I access values the second and third fareComponentGroupList ?
(I am sorry about these silly questions but I am new with swift Codables)
Since originDestinationOptionList returns an array of dictionary, just fetch it from there by index.
let originDestinationOptionList = root.availabilityResultList.first?.availabilityRouteList.first?.availabilityByDateList.first?.originDestinationOptionList
let firstobject = originDestinationOptionList[0]["fareComponentGroupList"]
let secondObject = originDestinationOptionList[1]["fareComponentGroupList"]
let firstObjectsFirstItem = firstObject[0]
If the above gives error, this works ( Swift 5)
let originDestinationOptionList = root.availabilityResultList.first?.availabilityRouteList.first?.availabilityByDateList.first?.originDestinationOptionList
let firstobject = originDestinationOptionList[0].fareComponentGroupList.first
let firstObjectsFirstItem = firstObject?. (add the remaining part)
in my Api call i getting response in [String : AnyObject] format from this i need to get few elements and store it on Array how to achieve this in Swift4 here my sample response could help how to get values from my response
My Sample Response :
["result": valid: (
{
id = 1;
"name" = "Alen"
},
{
id = 12;
"name" = "Peter"
},
{
id = 14;
"name" = "John"
},
{
id = 16;
"name" = "Ema"
},
{
id = 19;
"name" = "Shane"
},
{
id = 211;
"name" = "Mia"
}
)]
From this response i need to get all "name" values in array how to acheive this in swift 4
You can use swiftyJSON for seperate "name" from the response
let jsonData = JSON(data : data)
data - response of your api
then use forloop for adding name data in array
Hope so, this will help you.
struct Details{
let Name : String
}
And where you are getting result from server, use this code and after that your name values will be in Result Array.
var RecordsArr = [Details]()
let Result = recordJSON.value(forKey: "result") as? [NSDictionary]
for item in Result {
let id_records = Details(Name: item[“name”]! as! String)
RecordsArr.append(id_records)
}
Let me tell, if you have any problem.
Suppose i have json string in which there is a json array called data.
The array holds json object of user profile data for example name,age,gender etc.
Now want to parse that json object as per order, for example if the object is
{
"name": "sample name",
"age": "30",
"gender": "male"
}
i want to parse the list as ordered like name,age,gender but with ios,when i convert the json object as dictionary , the order is changed,i know dictionary is not ordered so what is the the alternative to achieve this?
its a third party api so i dont have any hand on it,we have done it in android with linked hash map,but really stuck in swift , the last thing i would want to do is parse with regular expression.
im parsing the json in following way :
var rootData = try JSONSerialization.jsonObject(with: data!) as! [String:Any]
if let val = fromList["data"] {
let dataNode = val as! [[String:Any]]
for row in dataNode {
for (key,keyVal) in row {
//here the key is not in order.because when we cast it as dictionary the order gets changed.
}
}
For android we have achieved to do this with following function :
public ArrayList<LinkedHashMap<String, Object>> parseJsonArrayList(String odata, String arrayName) {
ArrayList<LinkedHashMap<String, Object>> mylist = new ArrayList<>();
try {
JSONObject e = new JSONObject(odata);
JSONArray data = e.getJSONArray(arrayName);
for(int i = 0; i < data.length(); ++i) {
JSONObject v = data.getJSONObject(i);
LinkedHashMap<String, Object> map = new LinkedHashMap<>(100, 0.75f, false);
Iterator keys = v.keys();
while(keys.hasNext()) {
String key = String.valueOf(keys.next());
//gph.log("debug4", key);
map.put(key, v.getString(key));
//gph.log("debug4", v.getString(key));
}
mylist.add(map);
}
} catch (JSONException var10) {
var10.printStackTrace();
}
return mylist;
}
Don’t try to order the dictionary. Instead create an array of the keys in the order you desire:
let keys = [“name”, “age”, “gender”]
Then access the dictionary with them:
for key in keys {
let value = dict[key]
// Present the value.
}
That will ensure the order you expect.
As you mentioned you cannot get the ordered data in Dictionary. If possible you can add the "order" key in your JSON like
[
{
"name": "sample name",
"order": 1
},
{
"age": "30",
"order": 1
},
{
"gender": "",
"male": "",
"order": 1
}
]
so that based on the order key you can do the sorting.
{
"item": [
{
"pid": 89334,
"productsname": "Long Way",
"address": "B-4/7, Malikha Housing, Yadanar St., Bawa Myint Ward,",
"telephone": "[\"01570269\",\"01572271\"]"
},
{
"pid": 2,
"productsname": "Myanmar Reliance Energy Co., Ltd. (MRE)",
"address": "Bldg, 2, Rm# 5, 1st Flr., Hninsi St., ",
"telephone": "[\"202916\",\"09-73153580\"]"
}
],
"success": true
}
I cannot parse telephone value from above JSON object with following code.
for item in swiftyJsonVar["item"].array! {
if let jsonDict = item.dictionary {
let pid = jsonDict["pid"]!.stringValue
let productsname = jsonDict["productsname"]!.stringValue
var telephones = [String]()
for telephone in (jsonDict["telephone"]?.array)! {
telephones.append(telephone.stringValue)
}
}
}
I want to get and display one by one phone number of above JSON. I'm not sure why above code is not working. Please help me how to solve it, thanks.
Because telephone is a string that looks like an array, not an array itself. The server encoded this array terribly. You need to JSON-ify it again to loop through the list of telephone numbers:
for item in swiftyJsonVar["item"].array! {
if let jsonDict = item.dictionary {
let pid = jsonDict["pid"]!.stringValue
let productsname = jsonDict["productsname"]!.stringValue
var telephones = [String]()
let telephoneData = jsonDict["telephone"]!.stringValue.data(using: .utf8)!
let telephoneJSON = JSON(data: telephoneData)
for telephone in telephoneJSON.arrayValue {
telephones.append(telephone.stringValue)
}
}
}
When using the Alamofire Framework, my responses don't seem to be getting parsed correctly. The JSON response I get has some keys that appear to not be strings, and I don't know how to reference them/get their values.
Here is the part of my code that makes the call:
var url = "http://api.sandbox.amadeus.com/v1.2/flights/low-fare-search"
var params = ["origin": "IST",
"destination":"BOS",
"departure_date":"2014-10-15",
"number_of_results": 1,
"apikey": KEY]
Alamofire.request(.GET, url, parameters: params)
.responseJSON { (_, _, json, _) in
println(json)
}
}
And here is the first section printout when that function is called
Optional({
currency = USD;
results = ({
fare = {
"price_per_adult" = {
tax = "245.43";
"total_fare" = "721.43";
};
restrictions = {
"change_penalties" = 1;
refundable = 0;
};
"total_price" = "721.43";
};
...
});
});
You'll notice that results is not "results", but "price_per_adult" is the correct format. Is there some step I'm missing? When I cast it to NSDictionary it doesn't do anything to help the key format either.
I also tried the same endpoint in javascript and ruby, and both came back without problem, so I'm fairly confident that it is not the API that is causing problems.
Those keys are still Strings, that's just how Dictionarys are printlnd. It looks like it will surround the String in quotes when printing it only if it contains non-alphanumeric characters (_ in this case). You can test this by manually creating a Dictionary similar to the one you're getting back from your API request and then printing it:
let test = [
"currency": "USD",
"results": [
[
"fare": [
"price_per_adult": [
"tax": "245.43",
"total_fare": "721.43"
],
"restrictions": [
"change_penalties": 1,
"refundable": 0
],
"total_price": "721.43"
]
]
]
]
println(test)
Outputs:
{
currency = USD;
results = (
{
fare = {
"price_per_adult" = {
tax = "245.43";
"total_fare" = "721.43";
};
restrictions = {
"change_penalties" = 1;
refundable = 0;
};
"total_price" = "721.43";
};
}
);
}
