【问题描述】:
我真的很难解析这个 JSON (https://www.kimonolabs.com/api/7flcy3qm?apikey=gNq3hB1j0NtBdAvXJLEFx8JaqtDG8y6Y) 并用“日期”文本、“事件”文本、“Hasta”文字和“位置”文字。我意识到这对于非新手来说可能很容易。这是我可能很糟糕的代码:
import UIKit
import Foundation
class MasterTableViewController: UITableViewController {
var vigoData = [String]()
override func viewDidLoad() {
super.viewDidLoad()
splitViewController!.preferredDisplayMode = UISplitViewControllerDisplayMode.AllVisible
UINavigationBar.appearance().barTintColor = UIColor(red: 52.0/255.0, green: 170.0/255.0, blue: 220.0/255.0, alpha: 1.0)
UINavigationBar.appearance().tintColor = UIColor.whiteColor()
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]
let url = NSURL(string: "https://www.kimonolabs.com/api/7flcy3qm?apikey=gNq3hB1j0NtBdAvXJLEFx8JaqtDG8y6Y")!
let task = NSURLSession.sharedSession().dataTaskWithURL(url) { (data, response, error) -> Void in
if let urlContent = data {
do {
let jsonResult = try NSJSONSerialization.JSONObjectWithData(urlContent, options: NSJSONReadingOptions.MutableContainers)
if let eventData = jsonResult["Collection2"] as? [[String: AnyObject]] {
for event in eventData {
if let _ = event["Event"] as? String {
self.vigoData.append("text")
}
}
}
print(self.vigoData)
} catch {
print("JSON Serialization failed")
}
}
}
task.resume()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 0
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 0
}
【问题讨论】:
-
您可能希望将任务拆分为几个步骤并尝试一次修复每个步骤:1)在数据结构(元组数组)中提取您需要的数据,2)使用数据填写表格单元格的结构
-
想通过示例更深入地解释这一点吗?我是业余爱好者
-
例如尝试解析 JSON 文档并在元组数组中提取所需的值。您可以按照本教程学习如何在 Swift 中使用 JSON:raywenderlich.com/82706/working-with-json-in-swift-tutorial;这是另一个关于元组的教程:raywenderlich.com/115300/…
