3D Touch Quick Actions 无法与 SpriteKit 一起正常工作
3D Touch Quick Actions not working properly with SpriteKit
我目前正在使用 Swift 3、SpriteKit 和 Xcode 8 beta 开发游戏。我正在尝试通过 info.plist 从主屏幕实现静态 3D Touch 快速操作。目前,操作在主屏幕上看起来很好,但不会转到正确的 SKScene - 转到初始场景或最后打开的场景(如果应用程序仍处于打开状态),这意味着场景没有被更改。我尝试了各种在 switch 语句中设置场景的方法,但是 none 似乎可以正常显示 SKScene,因为行 window!.rootViewController?.present(gameViewController, animated: true, completion: nil)
仅适用于 UIViewController。
此代码的各个部分来自各种教程,但通过调查我相当确定损坏的部分是正在呈现的场景(除非我错了),因为它甚至不应该加载任何场景如果零件坏了。
有什么方法可以从 AppDelegate 呈现 SKScene 或根据 switch 语句设置开场场景?
AppDelegate
import UIKit
import SpriteKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
guard !handledShortcutItemPress(forLaunchOptions: launchOptions) else { return false } // ADD THIS LINE
return true
}
}
extension AppDelegate: ShortcutItem {
/// Perform action for shortcut item. This gets called when app is active
func application(_ application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
completionHandler(handledShortcutItemPress(forItem: shortcutItem))
}
}
extension AppDelegate: ShortcutItemDelegate {
func shortcutItem1Pressed() {
Timer.scheduledTimer(timeInterval: 0.5, target: self, selector: #selector(loadShopScene), userInfo: nil, repeats: false)
}
@objc private func loadShopScene() {
let scene = ShopScene(size: CGSize(width: 768, height: 1024))
loadScene(scene: scene, view: window?.rootViewController?.view)
}
func shortcutItem2Pressed() {
Timer.scheduledTimer(timeInterval: 0.5, target: self, selector: #selector(loadGameScene), userInfo: nil, repeats: false)
}
@objc private func loadGameScene() {
let scene = GameScene(size: CGSize(width: 768, height: 1024))
loadScene(scene: scene, view: window?.rootViewController?.view)
}
func shortcutItem3Pressed() {
// do something else
}
func shortcutItem4Pressed() {

}
func loadScene(scene: SKScene?, view: UIView?, scaleMode: SKSceneScaleMode = .aspectFill) {

guard let skView = view as? SKView else { return }
skView.ignoresSiblingOrder = true

您的代码无法正常工作,因为在您的应用委托中您创建了一个新的 GameViewController 实例,而不是引用当前实例
let gameViewController = GameViewController() // creates new instance
在我的 2 个游戏中,我正在使用 3d 触摸快速操作来做您想要做的事情。我直接从 appDelegate 加载场景,不要为此尝试更改 gameViewController 场景。
我为此使用了一个可重复使用的助手。假设您在 info.plist 中正确设置了所有内容。 (我在枚举中使用小写字母,所以在 info.plist 中以 .first、.second 等结束你的项目),删除你之前为 3d 触摸快速操作而拥有的所有应用程序委托代码。
比在您的项目中创建一个新的 .swift 文件并添加此代码
这是swift3码。
import UIKit
/// Shortcut item delegate
protocol ShortcutItemDelegate: class {
func shortcutItemDidPress(_ identifier: ShortcutItemIdentifier)
}
/// Shortcut item identifier
enum ShortcutItemIdentifier: String {
case first // I use swift 3 small letters so you have to change your spelling in the info.plist
case second
case third
case fourth
private init?(fullType: String) {
guard let last = fullType.componentsSeparatedByString(".").last else { return nil }
self.init(rawValue: last)
}
public var type: String {
return (Bundle.main.bundleIdentifier ?? "NoBundleIDFound") + ".\(rawValue)"
}
}
/// Shortcut item protocol
protocol ShortcutItem { }
extension ShortcutItem {
// MARK: - Properties
/// Delegate
private weak var delegate: ShortcutItemDelegate? {
return self as? ShortcutItemDelegate
}
// MARK: - Methods
func didPressShortcutItem(withOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
guard let shortcutItem = launchOptions?[.shortcutItem] as? UIApplicationShortcutItem else { return false }
didPressShortcutItem(shortcutItem)
return true
}
/// Handle item press
@discardableResult
func didPressShortcutItem(_ shortcutItem: UIApplicationShortcutItem) -> Bool {
guard let _ = ShortcutItemIdentifier(fullType: shortcutItem.type) else { return false }
switch shortcutItem.type {
case ShortcutItemIdentifier.first.type:
delegate?.shortcutItemDidPress(.first)
case ShortcutItemIdentifier.second.type:
delegate?.shortcutItemDidPress(.second)
case ShortcutItemIdentifier.third.type:
delegate?.shortcutItemDidPress(.third)
case ShortcutItemIdentifier.fourth.type:
delegate?.shortcutItemDidPress(.fourth)
default:
return false
}
return true
}
}
然后在您的应用程序委托中使用此方法创建一个扩展(您在代码中错过了这个)
extension AppDelegate: ShortcutItem {
/// Perform action for shortcut item. This gets called when app is active
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
completionHandler(didPressShortcutItem(shortcutItem))
}
您需要将 AppDelegate 中的 didFinishLaunchingWithOptions 方法调整为如下所示
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
...
return !didPressShortcutItem(withOptions: launchOptions)
}
最后创建另一个扩展以确认 ShortcutItem 委托
extension AppDelegate: ShortcutItemDelegate {
func shortcutItemDidPress(_ identifier: ShortcutItemIdentifier) {
switch identifier {
case .first:
let scene = GameScene(size: CGSize(width: 1024, height: 768))
loadScene(scene, view: window?.rootViewController?.view)
case .second:
//
case .third:
//
case .fourth:
//
}
}
func loadScene(scene: SKScene?, view: UIView?, scaleMode: SKSceneScaleMode = .aspectFill) {
guard let scene = scene else { return }
guard let skView = view as? SKView else { return }
skView.ignoresSiblingOrder = true
#if os(iOS)
skView.isMultipleTouchEnabled = true
#endif
scene.scaleMode = scaleMode
skView.presentScene(scene)
}
}
我通常在另一个帮助器中使用的加载场景方法,这就是为什么我将视图传递给函数的原因。
希望对您有所帮助。
