静态 Quick Actions

编辑 Info.plist 文件，如下图：

Info.plist

源码如下：

<key>UIApplicationShortcutItems</key>
    <array>
        <dict>
            <key>UIApplicationShortcutItemIconType</key>
            <string>UIApplicationShortcutIconTypeCompose</string>
            <key>UIApplicationShortcutItemTitle</key>
            <string>标签1</string>
            <key>UIApplicationShortcutItemType</key>
            <string>com.mycompany.myapp.item1</string>
            <key>UIApplicationShortcutItemUserInfo</key>
            <dict>
                <key>key1</key>
                <string>value1</string>
            </dict>
        </dict>
        <dict>
            <key>UIApplicationShortcutItemSubtitle</key>
            <string>副标题</string>
            <key>UIApplicationShortcutItemIconType</key>
            <string>UIApplicationShortcutIconTypeCloud</string>
            <key>UIApplicationShortcutItemTitle</key>
            <string>标签2</string>
            <key>UIApplicationShortcutItemType</key>
            <string>com.mycompany.myapp.item2</string>
            <key>UIApplicationShortcutItemUserInfo</key>
            <dict>
                <key>key2</key>
                <string>value2</string>
            </dict>
        </dict>
    </array>

动态 Quick Actions

AppDelegate 文件中添加如下代码：

private func handleDynamicQuickActions() {
        if 0 == UIApplication.sharedApplication().shortcutItems?.count {
            let newItem = UIApplicationShortcutItem(type: "com.mycompany.myapp.item3", localizedTitle: "dynamic标签3")
            UIApplication.sharedApplication().shortcutItems?.append(newItem)
        }
    }

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        handleDynamicQuickActions()
        return true
    }

func application(application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
        
        let type = shortcutItem.type
        if "com.mycompany.myapp.item1" ==  type {
            print("item1 selected")
        } else if "com.mycompany.myapp.item2" == type {
            print("item2 selected")
        } else if "com.mycompany.myapp.item3" == type {
            print("item3 selected")
        }
    }

当前 ViewController

class ViewController: UIViewController, UIViewControllerPreviewingDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        
        // Add test button
        let btn = UIButton(type: .System)
        btn.setTitle("Peek & Pop Test: click me", forState: .Normal)
        btn.sizeToFit()
        btn.backgroundColor = UIColor.yellowColor()
        btn.center = self.view.center

        self.view.addSubview(btn)
        
        // register preview
        if .Available == traitCollection.forceTouchCapability {
            registerForPreviewingWithDelegate(self, sourceView: btn)
        }
    }

    func previewingContext(previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
        return DetailViewController()
    }
    
    func previewingContext(previewingContext: UIViewControllerPreviewing, commitViewController viewControllerToCommit: UIViewController) {
        showViewController(viewControllerToCommit, sender: self)
    }
    
}

DetailViewController

class DetailViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        self.view.backgroundColor = UIColor.redColor()
    }
    
    override func previewActionItems() -> [UIPreviewActionItem] {
        let action1 = UIPreviewAction(title: "Action 1", style: .Default) { (action, viewController) -> Void in
            print("Action 1 selected")
        }
        
        let action2 = UIPreviewAction(title: "Action 2", style: .Destructive) { (action, viewController) -> Void in
            print("Action 2 selected")
        }
        
        return [action1, action2]
    }
    
}
