我创建了 5 个类，包括 ProfileHomeModel、ProfileLocationModel、ProfileRequestManager、ProfileTableUserViewController 和 ProfileTableViewCell。我的目标是正确解析 json 并显示数据。我在请求管理器类中遇到了问题。我对 swift 完全陌生。我想在不使用 swiftyJSON 和 Alamofire 的情况下做到这一点。
import Foundation
class ProfileRequestManager{
let urlPath = "*********"
let url = NSURL(string: urlPath)
let data = NSData(contentsOfURL: url!)
do {
let jsonData = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) as? NSDictionary
print(jsonData)
let results = jsonData!.objectForKey("strengths") as? [NSDictionary] ?? []
for result in results {
print(result)
}
}
catch {
print("Something went wrong while parsing json data fetched from the API")
}
}
json数据

我正在尝试归还上面的所有内容
我得到的错误是在做的事情上。Xcode给了我一个预期的声明错误。我检查了我的花括号。
希望能得到一些帮助来解决这个问题。
此外，出于安全目的，我不需要包含 url。我希望它有所帮助。
我也试图在单独的单元格中显示所有值。这就是我现在所拥有的。
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCellWithIdentifier("ProfileCell", forIndexPath: indexPath) as! ProfileUserTableViewCell
cell.firstName?.text = firstName
cell.lastName?.text = lastName
cell.title?.text = title
return cell
}
}
你知道我该如何解决这个问题吗？
这是我目前的情况。我无法让它显示在表格视图单元格上。问题似乎在于我如何将我的 json 值分配给标签。
