要给Swift应用添加3D Touch菜单,需要遵循以下步骤:
<key>UIApplicationShortcutItems</key>
<array>
<dict>
<key>UIApplicationShortcutItemTitle</key>
<string>Action 1</string>
<key>UIApplicationShortcutItemType</key>
<string>com.example.app.action1</string>
<key>UIApplicationShortcutItemIconType</key>
<string>UIApplicationShortcutIconTypePlay</string>
<key>UIApplicationShortcutItemUserInfo</key>
<dict>
<key>key1</key>
<string>value1</string>
</dict>
</dict>
...
</array>
在上述示例中,"UIApplicationShortcutItemTitle"是菜单项的标题,"UIApplicationShortcutItemType"是菜单项的标识符,"UIApplicationShortcutItemIconType"是菜单项的图标类型,"UIApplicationShortcutItemUserInfo"是菜单项的附加信息。
application(_:performActionFor:completionHandler:)
方法来处理用户点击3D Touch菜单项的操作。func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {
if shortcutItem.type == "com.example.app.action1" {
// 处理点击Action 1的操作
completionHandler(true)
} else if shortcutItem.type == "com.example.app.action2" {
// 处理点击Action 2的操作
completionHandler(true)
} else {
completionHandler(false)
}
}
在上述示例中,我们根据菜单项的类型来执行相应的操作,并在操作完成后调用completionHandler。
override func viewDidLoad() {
super.viewDidLoad()
let item1 = UIApplicationShortcutItem(type: "com.example.app.action1", localizedTitle: "Action 1", localizedSubtitle: nil, icon: UIApplicationShortcutIcon(type: .play), userInfo: [
"key1": "value1"
])
let item2 = UIApplicationShortcutItem(type: "com.example.app.action2", localizedTitle: "Action 2", localizedSubtitle: nil, icon: UIApplicationShortcutIcon(type: .pause), userInfo: [
"key2": "value2"
])
UIApplication.shared.shortcutItems = [item1, item2]
}
在上述示例中,我们创建了两个UIApplicationShortcutItem对象,并设置了相应的属性,包括类型、标题、图标和附加信息。然后将这些菜单项通过UIApplication.shared.shortcutItems属性设置给应用。
这样,当用户使用3D Touch手势点击应用图标时,就会出现相应的菜单项,点击菜单项后,应用会执行相应的操作。
