我正在努力从此站点获取Swapi(星球大战API) -> https://swapi.co/要在我的tableview单元格上填充,但我有点对如何抓住角色并显示所有空数阵列的内容感到困惑。变量"人"起作用,它抓住了这些确切的字符并在控制台中显示其数据。我该如何在ViewDidload()中进行此操作?这就是我到目前为止的。我也在Swift 2.3中这样做。
import UIKit
class PeopleViewController: UITableViewController {
// var people = ["Luke Skywalker", "Leia Organa", "Han Solo", "C-3PO", "R2-D2"]
var people = [Person]()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let url = NSURL(string: "http://swapi.co/api/people/")
// Create an NSURLSession to handle the request tasks
let session = NSURLSession.sharedSession()
// Create a "data task" which will request some data from a URL and then run a completion handler after it is done
let task = session.dataTaskWithURL(url!, completionHandler: {
data, response, error in
print("in here")
print(data)
do {
if let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary {
print(jsonResult)
if let results = jsonResult["results"] {
let resultsArray = results as! NSArray
print(resultsArray.count)
print(resultsArray.firstObject)
}
}
} catch {
print("Something went wrong")
}
})
task.resume()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// return the count of people
return people.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
// Create a generic cell
let cell = UITableViewCell()
// set the default cell label to the corresponding element in the people array
cell.textLabel?.text = people[indexPath.row]
// return the cell so that it can be rendered
return cell
}
}
您有正确的想法。您只需要填充您的人数组,然后告诉表观以重新加载(来自主线程)
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let url = NSURL(string: "http://swapi.co/api/people/")
// Create an NSURLSession to handle the request tasks
let session = NSURLSession.sharedSession()
// Create a "data task" which will request some data from a URL and then run a completion handler after it is done
let task = session.dataTaskWithURL(url!, completionHandler: {
data, response, error in
print("in here")
print(data)
do {
if let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary {
print(jsonResult)
if let results = jsonResult["results"] {
let resultsArray = results as! NSArray
print(resultsArray.count)
print(resultsArray.firstObject)
//------------------------------------------------------
//Install the array in people and tell the table view to
//reload
DispatchQueue.main.async() {
//Replace the code below with code create Person
//objects from your data.
people = resultsArray.map(){Person(name:$0)}
tableView.reloadData()
}
//------------------------------------------------------
}
}
} catch {
print("Something went wrong")
}
})
task.resume()
}
