我想从项目中可用的本地文件解析JSON数据，然后将这些数据填充到UITableView。
我的要求
从本地路径而不是从URL解析json数据
将json数据填充到UITableView
面临的问题
无法显示已分析的数据（括号显示在表视图中）。
我可以使用dump（）在控制台中打印数据，但无法在tableView中打印数据
已更新视图控制器，用于将数据传递到另一个控制器。
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return lookArrayModel.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cells = myTableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let displayData = lookArrayModel[indexPath.row]
cells.textLabel?.text = String(describing: displayData.Lookname!)
cells.detailTextLabel?.text = String(describing: displayData.Lookdetails!)
// print(displayData.shadeModel)
return cells
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("You selected cell #\(indexPath.row)!")
// Get Cell Label
let indexPath = myTableView.indexPathForSelectedRow;
let currentCell = myTableView.cellForRow(at: indexPath!) as UITableViewCell!;
lookNameValue = currentCell?.textLabel?.text
lookDetailValue = currentCell?.detailTextLabel?.text
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
//let lookShade = LookModelData()
if (segue.identifier == "segueToLook") {
let destController:DetailsViewController = segue.destination as! DetailsViewController
//Set the selecte row index value
destController.LabelText = String(describing: lookNameValue)
destController.DetailText = String(describing: lookDetailValue)
// destController.arrayData = lookShade.shadeModel as! NSMutableArray
}
}
}
目标视图控制器。斯威夫特
class DetailsViewController:UIViewController,UITableViewDataSource,UITableViewDelegate {
var lookArrayModel = [LookModelData]()
var arrayData: NSMutableArray = []
@IBOutlet weak var secondView: UITableView!
var LabelText = String()
var DetailText = String()
var shadeText = String()
@IBOutlet weak var LookLabel: UILabel!
@IBOutlet weak var LookName: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
print(arrayData)
LookName?.text = LabelText
LookLabel?.text = DetailText
secondView.dataSource = self
secondView.delegate = self
secondView.reloadData()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arrayData.count
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cells = secondView.dequeueReusableCell(withIdentifier: "secondCell", for: indexPath)
let displayData = arrayData
// cells.textLabel?.text = String(describing: (displayData as AnyObject))
// print(arrayData)
return cells
}
}
最佳答案
请检查我的代码：
将lookArrayModel类型NSMutableArray更改为[LookModelData]。就像那些我做了一些改变。请检查一下。
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var lookArrayModel = [LookModelData]()
@IBOutlet weak var myTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
guard let Path = Bundle.main.path(forResource: "ColorShade", ofType: "json") else { return }
let url = URL(fileURLWithPath: Path)
do {
let data = try Data(contentsOf: url)
let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers)
myTableView.dataSource = self
myTableView.delegate = self
//Calling the function for adding look
createLooks(dictionary: json as! NSArray)
myTableView.reloadData()
} catch {
print(error)
}
}
func createLooks(dictionary:NSArray) {
for item in dictionary {
let item1 = item as! NSDictionary
let lookModal = LookModelData()
lookModal.Lookname = item1.value(forKey: "Lookname") as? String
lookModal.LookId = item1.value(forKey: "LookId") as? String
lookModal.Lookdetails = item1.value(forKey: "Lookdetails") as? String
lookModal.shadeModel = createshade(shades: item1.value(forKey: "shades") as! NSArray)
lookArrayModel.append(lookModal)
}
}
func createshade(shades: NSArray) -> [ShadeDescription] {
var arrayShade = [ShadeDescription]()
for item in shades
{
let item1 = item as! NSDictionary
let shadeModal = ShadeDescription()
shadeModal.comboID = item1.value(forKey: "comboID") as? String
shadeModal.shadeName = item1.value(forKey: "shadeName") as? String
shadeModal.ShadeType = item1.value(forKey: "ShadeType") as? String
shadeModal.ShadeCode = item1.value(forKey: "shadeCode") as? String
arrayShade.append(shadeModal)
}
return arrayShade
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return lookArrayModel.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cells = myTableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let displayData = lookArrayModel[indexPath.row]
// You will get like this
// print(displayData.LookId!)
// print(displayData.Lookname!)
// print(displayData.Lookdetails!)
// print(displayData.shadeModel!)
// This is the way to get shade model data
if let shadeModels = displayData.shadeModel {
for var shadeModel in shadeModels {
print(shadeModel.comboID)
print(shadeModel.ShadeType)
print(shadeModel.shadeName)
print(shadeModel.ShadeCode)
}
}
cells.textLabel?.text = String(describing: displayData.Lookname!)
return cells
}
}
class LookModelData
{
var Lookname:String?
var LookId:String?
var Lookdetails:String?
//Shades Array
var shadeModel : [ShadeDescription]?
}
class ShadeDescription {
var ShadeType:String?
var shadeName:String?
var comboID:String?
var ShadeCode:String?
}
