暂停并继续玩app午餐/退出app ( SpriteKit Swift)

Question

我在游戏中有按钮暂停，它工作得很好！但当我再次退出应用程序或午餐应用程序时，我需要我的游戏暂停。

我希望屏幕是打开的，当我点击按钮时，暂停会在我返回游戏时打开

怎样才能做好呢？

Answer 1

您应该看到https://github.com/aaronabentheuer/AAWindow这个项目。首先，您应该添加打开的AppDelegate.swift和

var window: UIWindow? = {
    let window = AAWindow(frame: UIScreen.mainScreen().bounds, cornerRadius: 8)
    return window
    }()

之后添加您的项目。

func NC()

{
    NSNotificationCenter.defaultCenter().addObserverForName(UIApplicationDidBecomeActiveNotification, object: nil, queue: NSOperationQueue.mainQueue(), usingBlock: { notification in
    })
    NSNotificationCenter.defaultCenter().addObserverForName("applicationWillResignActiveWithoutControlCenter", object: nil, queue: NSOperationQueue.mainQueue(), usingBlock: { notification in
        //code
    })
}
func CC()
{
    NSNotificationCenter.defaultCenter().addObserverForName("applicationWillResignActiveWithControlCenter", object: nil, queue: NSOperationQueue.mainQueue(), usingBlock: { notification in
  //code
    })
}
func opened()
{
    NSNotificationCenter.defaultCenter().addObserverForName(UIApplicationDidBecomeActiveNotification, object: nil, queue: NSOperationQueue.mainQueue(), usingBlock: { notification in
        // code
    })
}

并创建新的快速文件并添加以下代码

import UIKit

class AAWindow: UIWindow {


private var activeCornerRadius : CGFloat = 0
private var inactiveCornerRadius : CGFloat = 0
private var cornerRadiusAnimationDuration : Double = 0.15

private var willOpenControlCenter : Bool = false
private var controlCenterOpened : Bool = false
var timer : NSTimer = NSTimer()

private var applicationWillResignActiveWithControlCenterNotification = NSNotification(name: "applicationWillResignActiveWithControlCenter", object: nil)

private var applicationWillResignActiveWithoutControlCenterNotification = NSNotification(name: "applicationWillResignActiveWithoutControlCenter", object: nil)

init(frame: CGRect, cornerRadius: Float) {
    super.init(frame: frame)

    self.clipsToBounds = true
    self.layer.cornerRadius = inactiveCornerRadius

    activeCornerRadius = CGFloat(cornerRadius)

    NSNotificationCenter.defaultCenter().addObserver(self, selector: "applicationDidBecomeActive:", name: UIApplicationDidBecomeActiveNotification, object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "applicationWillResignActive:", name: UIApplicationWillResignActiveNotification, object: nil)
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

@objc private func applicationDidBecomeActive (notification : NSNotification) {

    if (controlCenterOpened) {
        controlCenterOpened = false
    } else {
        self.layer.cornerRadius = activeCornerRadius

    }
}
@objc private func applicationWillResignActive (notification : NSNotification) {

    if (willOpenControlCenter) {

        NSNotificationCenter.defaultCenter().postNotification(applicationWillResignActiveWithControlCenterNotification)

        willOpenControlCenter = false
        controlCenterOpened = true
    } else {
        NSNotificationCenter.defaultCenter().postNotification(applicationWillResignActiveWithoutControlCenterNotification)

        self.layer.cornerRadius = inactiveCornerRadius
    }
}

private var touchLocation : CGPoint = CGPoint()

override func sendEvent(event: UIEvent) {
    super.sendEvent(event)

    if (event.type == UIEventType.Touches) {
        for touchevent in event.allTouches()! {
            let touch = touchevent

            if (touch.phase == UITouchPhase.Began && touch.locationInView(self).y - self.frame.height * 0.9 >= 0) {
                willOpenControlCenter = true
            }
        }
    }
}

}
