How to append the data from the JSON
How to append the data ?
my api as:-
[
{
"Name": "Vegetables",
"PictureModel": {
"ImageUrl": "http://example.jpeg"
}
},
{
"Name": "Fruits",
"PictureModel": {
"ImageUrl": "http://example1.jpeg"
}
}
]
for fetching the data from json
let session = URLSession.shared
session.dataTask(with: request) { (data, response, error) in
if let response = response {
print(response)
}
if let data = data {
do {
let json = try JSONSerialization.jsonObject(with: data, options: ) as! Array<[String:Any]>
print(json)
let type = json[0]
let name = type["Name"] as! String
let PictureModel = type["PictureModel"] as! [String:Any]
print(PictureModel)
let nameofimage = PictureModel["ImageUrl"] as! String
print(nameofimage)
self.fetchedHome.append(Categories(name: name, images: nameofimage))
self.tableview.reloadData()
} catch {
print(error)
}
}
}.resume()
And i got the output in the tableview .In tableview i got first data as name-vegetable and image in UIImageview.
.But second data not display .So how to append ? how to give for loop and append

Use this code you will get one by one object in For loop:-
if let data = json as? NSArray {
for data in data {
if let data = data as? [String: AnyObject] {
//Here you will get data
print("Name", data["Name"])
}
}
}
Are you getting JSON correctly in print(json)?
If yes, then you should try looping on "json" as follows :-
for (var keyAttr in json) {
let dataRow = json[keyAttr]
}
Inside the dataRow you can get "Name" and "PictureModel".
I am hoping that it should work.
All the best.
let session = URLSession.shared
session.dataTask(with: request) { (data, response, error) in
if let response = response {
print(response)
}
if let data = data {
do {
let json = try JSONSerialization.jsonObject(with: data, options: ) as! Array<[String:Any]>
if let data = json as? [String:Any] {
for data in data {
let name = data["Name"] as! String
let PictureModel = data["PictureModel"] as! [String:Any]
print(PictureModel)
let nameofimage = PictureModel["ImageUrl"] as! String
print(nameofimage)
self.fetchedHome.append(Categories(name: name, images: nameofimage))
}
}
self.tableview.reloadData()
} catch {
print(error)
}
}
}.resume()
