A statement
He has not made essays, and there are now more than a year. Also I want to continue to write essays period, but was delayed due to various reasons. Recently thought for a moment, there are still many things you want to write, you want to share, you want something recorded. Then I will continue to write essays, but not only for iOS direction, but also want to experience new things. In this much to say, we start reading the text of it.
Brief introduction
On supported 3D Touch devices, Quick Actions allows users to quickly and fewer steps to accomplish what they usually do, where so much can be done directly from the main screen. Such as micro hard to press the letter icon will pop up, such as "sweep swept away" and "My two-dimensional code" and other common functions, which I often used in the case of adding a friend, not a "sweep" of others is to be someone else. " sweep". Then this is its official presentation, 3D Touch - iOS - the Apple Developer .

Supported devices from iOS 9.0 is the start to support 3D Touch in iPhone 6S and 6S Plus and iPhone series of follow-up out of the system.
Info.plist Create Shortcut
Shortcuts defined in the Info.plist direct support, the primary key is UIApplicationShortcutItemsthat it is an array Array. Key values each can view the Information Property List Key Reference , here a brief introduction about the role of each Key.
| Key | effect |
|---|---|
| UIApplicationShortcutItemType (required) | Uniquely identifies |
| UIApplicationShortcutItemTitle (required) | The title of the show |
| UIApplicationShortcutItemSubtitle (optional) | The subtitle display |
| UIApplicationShortcutItemIconType (optional) | Icon using the system |
| UIApplicationShortcutItemIconFile (optional) | Using the Project icon |
| UIApplicationShortcutItemUserInfo (optional) | Additional information |
The following is a detailed example of the above-described UIApplicationShortcutItemUserInfo Key addition, the other are achieved.
Now we look at operating results, it is worth mentioning that, in the case of icons on the screen half and the lower half of the screen, displaying the sort that will be different, as shown in the following specific operating results.
Icon in the upper half of the screen
Icon in the lower half screen
Which determines whether the user clicks the shortcut
By implementing proxy method UIApplicationDelegate in AppDelegate.m file application:performActionForShortcutItem:completionHandler:, which the user can know a shortcut from coming in, specific code as follows.
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler API_AVAILABLE(ios(9.0)) {
NSLog(@"%s", __FUNCTION__);
if ([shortcutItem.type isEqualToString:@"search"]) {
NSLog(@"用户从快捷方式“搜索”进来的");
} else if ([shortcutItem.type isEqualToString:@"list"]) {
NSLog(@"用户从快捷方式“榜单”进来的");
} else if ([shortcutItem.type isEqualToString:@"public"]) {
NSLog(@"用户从快捷方式“一键发布”进来的");
}
}Code Create Shortcut
Shortcuts also supports code creation, each UIApplicationShortcutItem is a shortcut, the general method is implemented in AppDelegate.m file application:didFinishLaunchingWithOptions:write the implementation code, the code easier to understand, there is no longer explained.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSLog(@"%s", __FUNCTION__);
if (@available(iOS 9.0, *)) {
UIApplicationShortcutIcon *searchIcon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeSearch];
UIApplicationShortcutItem *search = [[UIApplicationShortcutItem alloc] initWithType:@"search" localizedTitle:@"搜索" localizedSubtitle:nil icon:searchIcon userInfo:nil];
UIApplicationShortcutIcon *publicIcon = [UIApplicationShortcutIcon iconWithTemplateImageName:@"upload"];
UIApplicationShortcutItem *public = [[UIApplicationShortcutItem alloc] initWithType:@"public" localizedTitle:@"一键发布" localizedSubtitle:nil icon:publicIcon userInfo:nil];
UIApplicationShortcutItem *list = [[UIApplicationShortcutItem alloc] initWithType:@"list" localizedTitle:@"榜单" localizedSubtitle:@"全区排行" icon:nil userInfo:nil];
application.shortcutItems = @[list, public, search];
}
return YES;
}data

Xcode: Version 10.1 (10B61)
Test models: iPhone XS Max
Test System: iOS 12.1
to sum up
Whether you are creating Quick Actions in info.plist or code are relatively simple, nothing complicated logic, it is easy to learn.
Quick Actions 的使用情况还是比较多的，就我而言，我经常会用支付宝和微信放出来的"扫一扫"，支付宝的"乘车码"等等。
3D Touch 的应用范围不止这些，还有 Peek and Pop 和 Pressure Sensitivity，在以后或许会补上这系列的文章。
