这肯定会被问过几次,但我还没有找到正确的答案,尽管我一直很努力.
我使用Alamofire和SwiftyJSON,我的JSON数据看起来像这样：
{
"528" : {
"name" : "Name 1","id" : "528","product_id" : null,"visible" : "0","level" : "2"
},"29" : {
"name" : "Name 2","id" : "29","visible" : "1","level" : "1"
},"173" : {
"name" : "Name 3","id" : "173","143" : {
"name" : "Name 4","id" : "143",
…使用此代码：
Alamofire.request(.GET,dataURL,parameters: nil,encoding: .JSON)
.responseJSON { (request,response,jsonData,error) in
let json = JSON(jsonData!)
println(json)
}
…所以JSON一切都应该没问题
>我如何访问该数据？我的意思是我如何获得名称,ID,product_ids等
>我如何将该数据(名称)放入我的TableViewController？
解决方法
我在我的一个项目中使用了SwiftyJSON和Alamofire.这是我如何使用它.
>创建一个名为APIProtocol的协议.
>使用GET方法设置API类,该方法接受APIProtocol类型的委托.
>设置TableViewController以实现APIProtocol.
>从TableViewController调用API.get()
码
// Step 1
protocol APIProtocol {
func didReceiveResult(results: JSON)
}
// Step 2
func get(path: String,parameters: [String: AnyObject]? = nil,delegate: APIProtocol? = nil){
let url = "\(self.hostname)\(path)"
NSLog("Preparing for GET request to: \(url)")
Alamofire.request(.GET,url,parameters: parameters)
.responseJSON { (req,res,json,error) in
if(error != nil) {
NSLog("GET Error: \(error)")
println(res)
}
else {
var json = JSON(json!)
NSLog("GET Result: \(json)")
// Call delegate if it was passed into the call
if(delegate != nil) {
delegate!.didReceiveResult(json)
}
}
}
}
// Step 3
class ActivityViewController: UITableViewController,APIProtocol {
var activityModelList: NSMutableArray = [] // This is the array that my tableView is using.
...
func didReceiveResult(result: JSON) {
var activities: NSMutableArray = []
NSLog("Activity.didReceiveResult: \(result)")
for (index: String,activity: JSON) in result {
var activityModel = ActivityModel(
id: activity["id"].intValue,message: activity["message"].stringValue
)
activities.addObject(activityModel)
}
// Set our array of new models
activityModelList = activities
// Make sure we are on the main thread,and update the UI.
dispatch_sync(dispatch_get_main_queue(),{
self.refreshControl!.endRefreshing()
self.tableView.reloadData()
})
}
}
// Step 4
override func viewDidLoad() {
MyAPI.get("/activities",delegate: self)
}
