JSON->Dictionary->Model?
1. Take a look at the data returned by json. It is recommended that you use AFN to request. The returned data response is an object dictionary or array, because json is generally packaged into an array (the array is also a dictionary in fact) or a dictionary. You can Go to json.cn to directly see the detailed structure of the returned data
2. Set a model. The attribute names required to be defined in the model are the same as the key values of the dictionary because kvc is used to directly convert the dictionary to the model
Definition and assignment of simple models:
Model definition
`import UIKit
class UserInfo: NSObject {
var screen_name:String?
var profile_image_url:String?
var verified: Int = -1
var mbrank: Int = 0
// kvc 遍历赋值
init(dict:[String:AnyObject]) {
super.init()
setValuesForKeysWithDictionary(dict)
}
// 防止未定义属性未赋值报错
override func setValue(value: AnyObject?, forUndefinedKey key: String) {
}
}`
If you want to assign a value, just take the attributes of the instantiated model and assign it to the cell when it needs it
Supplement: In this way, the data source is an array and stores multiple sets of data you need at the same time

Don’t use models to return cells. One is the model and the other is the view. The two should be separated as much as possible. You are doing the right thing. But it is best to make a table_nameAndIdArray. Each element of this array is a name and id (you can use tuple, struct or class).
