我想在OSX桌面的軟件中使用Parse PFUser。當我嘗試使用PFUser.query()時,它會發出一條消息:Failed to set (contentViewController) user defined inspected property on (NSWindow): The class PFUser must be registered with registerSubclass before using Parse.
解析PFUser未註冊子類
這是在沒有註冊類的情況下發生的。
我試着用這種方式註冊類:PFUser.registerSubclass()
但它仍然不起作用。
我將使用默認PFUser而不添加任何字段,所以我不需要創建一個自定義類作爲我的PFUser。
我試圖用PFUser.enableAutomaticUser()
沒有成功
代碼:
AppDelegate.swift
import Cocoa
import Parse
import Bolts
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
let APP_ID = "app_id"
let CLIENT_KEY = "client_key"
let SERVER = "https://parseserver.com/"
func applicationDidFinishLaunching(_ aNotification: Notification) {
PFUser.registerSubclass()
let configuracaoParse = ParseClientConfiguration {
$0.applicationId = self.APP_ID
$0.clientKey = self.CLIENT_KEY
$0.server = self.SERVER
}
Parse.initialize(with: configuracaoParse)
}
func applicationWillTerminate(_ aNotification: Notification) {
// Insert code here to tear down your application
}
}
ViewController.swift
import Cocoa
import Parse
class ViewController: NSViewController {
@IBOutlet weak var emailTextField: NSTextField!
@IBOutlet weak var senhaSecureTextField: NSSecureTextField!
override func viewDidLoad() {
super.viewDidLoad()
contaUsuarios()
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
@IBAction func entrarButtonClicked(_ sender: NSButton) {
}
func contaUsuarios() {
let query = PFUser.query()
query?.countObjectsInBackground(block: {
(count, error) -> Void in
let numeroUsers = Int(UInt32(count))
if numeroUsers > 0 {
}
print(numeroUsers)
})
}
}
