Ios 解析JSON Swift表视图
我想从这个jsonurl()中提取“Event”、“Hasta”和“Location”,但我正在努力解决如何做到这一点?有人能帮我吗?这是我的密码。。。然后我想用这3个参数填充一个tableviewIos 解析JSON Swift表视图,ios,json,swift,parsing,tableview,Ios,Json,Swift,Parsing,Tableview,我想从这个jsonurl()中提取“Event”、“Hasta”和“Location”,但我正在努力解决如何做到这一点?有人能帮我吗?这是我的密码。。。然后我想用这3个参数填充一个tableview override func viewDidLoad() { super.viewDidLoad() splitViewController!.preferredDisplayMode = UISplitViewControllerDisplayMode.AllVisible

用Swift解析JSON简直是地狱。你可以很容易地做到这一点 使用JSON:
// Get content of json url
let jsonString = try NSString.init(contentsOfURL: url!, encoding: NSUTF8StringEncoding)
// Create JSON object from data
let json = JSON(data: jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!)
// Check if array for key "collection2" exists
if let collection2 = json["results"]["collection2"].array {
// Create JSON array from it and loop for each object
for (key, subJson):(String, JSON) in JSON(collection2) {
// Check if dictionary for key "Event" exists
if let event = subJson["Event"].dictionary {
print(event)
}
// Check if string for key "Hasta" exists
if let hasta = subJson["Hasta"].string {
print(hasta)
}
// Check if string for key "Location" exists
if let location = subJson["Location"].string {
print(location)
}
}
}
我创建了这个在线实用程序(),它可以将json转换为swift可表示模型,您可以像这样轻松地进行操作:
// Get content of json url
let jsonString = try NSString.init(contentsOfURL: url!, encoding: NSUTF8StringEncoding)
// Create JSON Dictionary from data
var jsonResult = NSJSONSerialization.JSONObjectWithData(jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, options: NSJSONReadingOptions.MutableContainers, error: &err) as NSDictionary
//Create instance for base model representation
let responseModel = Json4Swift_Base(dictionary: jsonResult)
//print name
print(responseModel!.name)
//Get the collection2 from result
let collection2 = responseModel?.results!.collection2
//Get the first object from collection 2
let firstObject = collection2?.first
//Print the event and hesta
print(firstObject?.event?.text)
print(firstObject?.hasta)
对于tableview,您将实现委托方法CellForRowatineXpath
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("YourCellIdentifier")
if cell == nil {
cell = UITableViewCell()
}
//Assuming you have responseModel instantiated earlier
let collection2 = responseModel?.results!.collection2!
//Get the n'th object from collection 2
let object = collection2[indexPath.row]
//Populate the cell the event and hesta
cell.textLabel?.text = object?.event?.text
cell.detailTextLabel?.text = object?.hasta
return cell
}
免责声明:把上面的代码看作是一个伪代码,而不是实际测试过的,但是给了你关于处理的想法。
优秀的KiTunx。谢谢。是的,用斯威夫特解析它真是一场噩梦!如何用“事件”、“Hasta”和“位置”的文本填充tableview?在collection2中循环之后,您可以将所有子对象存储到NSArray
。然后使用UITableView
显示带有UITableViewDelegate
和UITableViewDataSource
的数据。关于如何在iOS中创建表视图,有很多很好的教程。你应该到处找一个。
