使用的Xcode 7.1遍歷對象斯威夫特 - 陣列出指數 - AlamofireObjectMapper在TableView中
我試圖做一個請求以下JSON，並顯示在一個的tableView
我使用AlamofireObjectMapper到JSON轉換對象。
問題：我不知道如何來遍歷對象的tableView
下面是自定義類，Alamofire請求&的TableView
類
class WeatherResponse: Mappable {
var location: String?
var threeDayForecast: [Forecast]?
required init?(_ map: Map){}
func mapping(map: Map) {
location <- map["location"]
threeDayForecast <- map["three_day_forecast"]
}
}
class Forecast: Mappable {
var day: String?
var temperature: Int?
var conditions: String?
required init?(_ map: Map){}
func mapping(map: Map) {
day <- map["day"]
temperature <- map["temperature"]
conditions <- map["conditions"]
}
}
Alamofire請求
//Defined within ViewController
var location: String?
var arrayOfForecasts = [Forecast]()
override func viewDidLoad() {
Alamofire.request(.GET, url).responseObject{(response :WeatherResponse?, error: ErrorType?)in
let location1 = response?.location
self.location = location1
let threeDayForecast1 = response?.threeDayForecast
self.arrayOfForecasts = threeDayForecast1!
print(threeDayForecast1)
self.tableView.reloadData()
} }
當我 '打印（threeDayForecast1）' 我得到以下輸出： [MyAppName.Forecast，MyAppName.Forecast，MyAppName.Forecast]
的TableView協議
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! TableViewCell
let threeDayObj1 = arrayOfForecasts[indexPath.row]
cell.tempLabel?.text = threeDayObj1.conditions
return cell
}
我得到錯誤如下：
threeDayObj1 is array out of index
你從哪裏得到錯誤？ threeDayObj1是三天？ – ciccioska
對不起，有一個錯字錯誤..我糾正了它..錯誤是在行threeDayObj1 = arrayOfForecasts [indexPath.row] –
