Today Extension和3D Touch

Today Extension

1.点击文件，选择如下图

2.选择scheme为demo，run之后显示“hello world”

在MainInterface.storyboard里或在TodayViewController里的viewdidload方法里布局UI（跟app开发一样）

3.当需要与主app共享数据时，需配置App Group，具体如下图

注：App Group为空时，请点左下角的”+”

1	let userDefault = UserDefaults(suiteName: "group.shine")!

使用userDefault来存储需要共享的数据

4.当extension需要调用主app的方法时通过URL方式

1
2
3

self.extensionContext?.open(URL(string: "shineDemo://todayExtension?index=0")!, completionHandler: { (res) in
            
        })

主App配置URL的scheme

3D Touch

上代码（动态3D Touch方式）

guard let filePath = Bundle.main.url(forResource: "3dtouchdemo", withExtension: "json"),
    let data = try? Data.init(contentsOf: filePath),
        let json = (try? JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.mutableContainers)) as? [[String: Any]] else {
    return
}
    
var items = [UIApplicationShortcutItem]()
for jsonItem in json {
    let icon = UIApplicationShortcutIcon(type: shortcutIconWithType(jsonItem["icon"] as! String))
    let item = UIApplicationShortcutItem(type: jsonItem["icon"] as! String, localizedTitle: jsonItem["title"] as! String, localizedSubtitle: (jsonItem["subtitle"] as! String), icon: icon, userInfo: jsonItem["userInfo"] as? [AnyHashable : Any])
    items.append(item)
}
UIApplication.shared.shortcutItems = items

附：3dtouchdemo.json

[{
    "icon": "add",
    "title": "增加",
    "subtitle": "增加-add",
    "userInfo": {
        "type": "add"
    }
 },{
     "icon": "alarm",
     "title": "闹钟",
     "subtitle": "闹钟-alarm",
     "userInfo": {
         "type": "alarm"
     }
 }]

在AppDelegate委托方法里实现点击后的事件处理，可以通过UIApplicationShortcutItem的type来判断不同的Item
