ios - 为什么从 json 响应显示在 tableView 无序列表值 swift 5
问题描述
在此处输入图像描述导入 UIKit
类 MyCircleViewPresenter：BaseViewPresenter {
typealias V = MyCircleViewDelegate
var mView: V?
func getMyCircle(url: String){
mView?.onNetworkCallStarted("please_wait".localized())
AlamofireService.getSession()
.request(url, method: .get).validate()
.responseJSON { (response) in
self.mView?.onNetworkCallEnded()
switch(response.result){
case .success(_):
guard let decodedObj = response.decode(objectType: MyCircleResponse.self) else {
self.mView?.myCircleDidReceived(response: nil)
return
}
self.mView?.myCircleDidReceived(response: decodedObj)
break
case .failure(let error):
self.mView?.handleError(httpSatusCode: response.response?.statusCode, errorData: response.data, error: error)

解决方案
JSON 响应永远不会以某种方式排序。它总是以不同的顺序出现，并被如此解码。我建议您自己按日期或其他方式对数组进行排序，以获得一致的对象顺序。
