【问题描述】:
我在 TableView 中显示 JSON 数组时遇到问题 - 结果是一个空白表,我知道它设置正确,因为它与固定数据数组一起使用。我似乎能够正确解析 JSON,因为我能够在控制台中操作打印输出,我认为问题是重新加载表函数但是我尝试了我在网上找到的解决方案的每一个变体,但似乎无法让它工作。 实际的 JSON 如下所示:
[{
"locationNumber": 10,
"locationName": "Test Site",
"locationPhoneNumber": "",
"locationAddress": "test address"
},
{
"locationNumber": 99,
"locationName": "Test Site2",
"locationPhoneNumber": "",
"locationAddress": "second test address"
}]
LocationTableViewController
import UIKit
import Alamofire
import AlamofireObjectMapper
class LocationTableViewController: UITableViewController {
var locations = [LocationResponse]()
override func viewDidLoad() {
super.viewDidLoad()
getLocationResponse()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return locations.count}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellIndentifier = "Cell"
let cell = tableView.dequeueReusableCellWithIdentifier(cellIndentifier, forIndexPath: indexPath) as! LocationTableViewCell
//configure the cell
cell.locationLabel.text = locations[indexPath.row].locationName
cell.locationidLabel.text = "$\(locations[indexPath.row].locationID)"
return cell
}
func getLocationResponse() {
let URL = "https://test.com.au/api/Store?uid=7654380A-D18F-46A1&username=app&password=apptest"
Alamofire.request(.GET, URL).responseArray { (response: Response<[LocationResponse], NSError>) in
let locationArray = response.result.value
if let locationArray = locationArray {
for location in locationArray {
print(location.locationID)
print(location.locationName)
}
}
}
}
LocationResponse.swift
import Foundation
import ObjectMapper
class LocationResponse: Mappable {
var locationName: String?
var locationID: Int?
required init?(_ map: Map){
}
func mapping(map: Map) {
locationName <- map["locationName"]
locationID <- map["locationNumber"]
}
}
自定义单元格:
import UIKit
class LocationTableViewCell: UITableViewCell {
@IBOutlet var locationLabel: UILabel!
@IBOutlet var locationidLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
我在控制台中从 print 函数中得到这个,看起来正确,我猜这意味着数组已正确创建:
Optional(10)
Optional("Test Site")
Optional(99)
Optional("Test Site2")
如果可以的话请帮忙
