1、按压应用图标显示Item列表
1.1 代码添加item
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// 长按图标 显示的列表项
let item = UIApplicationShortcutItem(type: "test.xiaopao.item", localizedTitle: "title", localizedSubtitle: "subtitle", icon: UIApplicationShortcutIcon(type: .add), userInfo: ["key" : "value"] as [String : NSSecureCoding])
application.shortcutItems = [item]
let window = UIWindow()
window.rootViewController = ViewController()
window.makeKeyAndVisible()
self.window = window
return true
}
1.2 点击item的 处理
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {
// 创建item时的 type，根据type来区分哪个item点击进来的
let type = shortcutItem.type
switch type {
case "test.xiaopao.item":
// doAction
break
default:
// doAction
break
}
}
2、应用内 3Dtouch (Peek & Pop功能）
概述:
Peek和Pop是应用内的一种全新交互模式,当用户不断增加力量在控件上按压,会依次进入四个阶段：
1、轻按控件,除触发Peek的控件外,其他区域全部虚化
2、继续用力Peek被触发,展示Pop界面快照
3、向上滑动展示快捷选项
4、继续用力跳转进入Pop界面
2.1 源控制器
// 遵守 UIViewControllerPreviewingDelegate协议
class ViewController: UIViewController, UIViewControllerPreviewingDelegate {
// 按压要弹出的控制器
var previewVc: PreviewViewController!
// 按压的view
var touchView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .white
touchView = UIView()
touchView.backgroundColor = .red
touchView.frame = CGRect(x: 100, y: 100, width: 100, height: 100)
view.addSubview(touchView)
previewVc = PreviewViewController()
// 检查页面是否属于3Dtouch
if self.responds(to: #selector(getter: traitCollection)) {
if self.traitCollection.forceTouchCapability == .available {
self.registerForPreviewing(with: self , sourceView: self.view)
}
}
}
func previewingContext(_ previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
// 按压要显示的controller
return previewVc
}
func previewingContext(_ previewingContext: UIViewControllerPreviewing, commit viewControllerToCommit: UIViewController) {
// 按压弹出controller 之后继续按压跳转
self.show(viewControllerToCommit, sender: self)
}
}
2.2 弹出的控制器
重写 previewActionItems 属性
class PreviewViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .green
preferredContentSize = CGSize(width: 300, height: 200)
let backButton = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 100))
backButton.setTitle("返回", for: .normal)
backButton.titleLabel?.textColor = .black
backButton.addTarget(self, action: #selector(backAction), for: .touchUpInside)
view.addSubview(backButton)
}
@objc func backAction() {
dismiss(animated: true, completion: nil)
}
override var previewActionItems: [UIPreviewActionItem] {
return [
UIPreviewAction(title: "title", style: .default, handler: { (action, vc) in
// doAction
})
]
}
}
