我创建了5个类，其中包括Profile Homemodel，ProfileLocationModel，ProfilereQuestManager，ProfileTableEserviewController和ProfileTable ViewCell。我的目标是正确解析JSON并显示数据。我已经在我的Request Manager课程中遇到了一个问题。我是Swift的新手。我想在不使用swiftyjson和alamofire的情况下这样做。
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")
}
}
jsondata

我试图将其归还上面的所有内容
我遇到的错误是在捕获上。Xcode给我带来了预期的声明错误。我检查了我的卷发。
很高兴能解决这个问题。
另外，我不需要为安全目的包含URL。我希望它有帮助。
我还试图在单独的单元格中显示所有值。这就是我现在拥有的。
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
}
}
您知道我如何解决此问题吗？
这是我目前的情况。我无法在表观视图单元格上显示它。问题似乎与我如何将JSON值分配给标签。
导入Uikit

这是您可以采取序列化JSON的一小部分尝试。我在viewDidLoad()块中实现了以下代码，以在Xcode Console中成功打印JSON数据。
let requestURL: NSURL = NSURL(string: "https://*******************")!
//Your baseURL
let urlRequest: NSMutableURLRequest = NSMutableURLRequest(URL: requestURL)
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(urlRequest) {
(data, response, error) -> Void in
let httpResponse = response as! NSHTTPURLResponse
let statusCode = httpResponse.statusCode
if (statusCode == 200) {
print("Everyone is fine")
do {
let JSON = try NSJSONSerialization.JSONObjectWithData(data!, options:NSJSONReadingOptions(rawValue: 0))
guard let JSONDictionary :NSDictionary = JSON as? NSDictionary else {
print("Not a Dictionary")
return
}
// print("JSONDictionary! (JSONDictionary)")
if let profile = JSONDictionary["profile"] as? NSDictionary {
print(profile)
//This is where we should begin parsing json into whatever you want to
let biography = profile["biography"] as? String
let designations = profile["designations"] as? String
let dob = profile["dob"] as? String
let doh = profile["doh"] as? String
let email = profile["email"] as? String
// do the same for firstname, goals, interests, lastname, location, mentors, phone, skills, speciality
print(biography!, designations, dob!)
let settings = profile["settings"] as? NSDictionary
let enableSMS = settings!.valueForKey("enable_sms") as? String
print(enableSMS!)
let strengths = profile["strengths"] as? NSArray
for eachItem in strengths! {
let color = eachItem.valueForKey("color") as? String
let description = eachItem.valueForKey("description")
let id = eachItem.valueForKey("id")
let name = eachItem.valueForKey("name")
print(name!, description!, color!, id!)
}
}
}
catch let JSONError as NSError {
print("(JSONError)")
}
}
}
task.resume()
我希望这对您有帮助。播放数组和词典，您将能够从API中提取所有值。
