如何使用 Alamofire 和 SwiftyJSON 将数据发送到 table 视图
How to send data to table view with Alamofire And SwiftyJSON
我有(大量)数据要发送给 Table 使用 alamofire 和 siftyJSON 查看
网络请求:
let postEndPoint :String = "http://jsonplaceholder.typicode.com/posts/"
编码 Alamofire 和 SwiftyJSON:
override func viewDidLoad() {
super.viewDidLoad()
Alamofire.request(.GET, postEndPoint).responseJSON { response in
// handle json
guard response.result.error == nil else{
print("error calling Get on /posts/1")
print(response.result.error)
return
}
if let value: AnyObject = response.result.value{
let post = JSON(value)
// for i in 0...post.count{
if let title = post["data"].arrayValue as? [JSON]{
self.datas = title
self.tableView.reloadData()
print("the title is :\(title)" )
}else{
print("eror parsing /post/1 ")
}
// }
}
}
}
代码table视图:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell : UITableViewCell = tableView.dequeueReusableCellWithIdentifier("Cell")!
var dict = datas[indexPath.row]
cell.textLabel?.text = dict["userId"] as? String
cell.detailTextLabel?.text = dict["id"] as? String
return cell
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return datas.count
}
}

我正在尝试 post 一些 json 数据以 table 查看,但是当我发送数据时 returns 什么都没有。为什么??
这是适合我的代码。最主要的是你必须在 api 调用结束时重新加载 table。并且您将 nuber 打印为字符串,因此您必须将其转换为字符串
我的代码在这里
import UIKit
class 自定义单元格:UITableViewCell {
@IBOutlet weak var lbl1: UILabel!
@IBOutlet weak var lbl2: UILabel!
}
class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
@IBOutlet weak var tabledata: UITableView!
let postEndPoint :String = "http://jsonplaceholder.typicode.com/posts/"
var arr:NSMutableArray = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
web()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("customcell") as! customcell
let dict = arr[indexPath.row] as! NSDictionary
print(dict)
print(dict["userId"])
cell.lbl1?.text = String (dict["userId"]! )
cell.lbl2?.text = String (dict["id"]! )
return cell
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arr.count
}
func web()
{
request(.GET, postEndPoint, parameters: nil, encoding:
.JSON).responseJSON { (response:Response<AnyObject, NSError>) -> Void in
print(response.result.value)
if (response.result.value != nil)
{
self.arr = (response.result.value) as! NSMutableArray
}
self.tabledata.reloadData()
}
}
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if (tableView == tabledata)
{
let cell = tableView.dequeueReusableCellWithIdentifier("customcell") as! customcell
let dict = arr[indexPath.row] as! NSDictionary
cell.lbl1?.text = String (dict["userId"]! )
cell.selectionStyle = .None
return cell
}
else if(tableView == tablefactoryoption)
{
let cell1:Facturyoptioncell = tableView.dequeueReusableCellWithIdentifier("Facturyoptioncell") as! Facturyoptioncell
let dict = arr[indexPath.row] as! NSDictionary
cell1.lbl2?.text = String (dict["Id"]! )
cell1.selectionStyle = .None
cell1.selectionStyle = .None
return cell1
}
else
{
let cell2:Technicalcell = tableView.dequeueReusableCellWithIdentifier("Technicalcell") as! Technicalcell
let dict = arr[indexPath.row] as! NSDictionary
cell2.lbl3?.text = String (dict["userId"]! )
return cell2
}
}
这就是使用多个表格视图显示数据的方法。
