一、3D Touch 的实现：

1.在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中实现添加和分享的入口，代码如下 ：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    UIApplicationShortcutIcon *firstItemIcon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeAdd];
    UIMutableApplicationShortcutItem *firstItem = [[UIMutableApplicationShortcutItem alloc]initWithType:@"First" localizedTitle:@"添加" localizedSubtitle:nil icon:firstItemIcon userInfo:nil];

    UIApplicationShortcutIcon *secondItemIcon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeShare];
    UIMutableApplicationShortcutItem *secondItem = [[UIMutableApplicationShortcutItem alloc]initWithType:@"Second" localizedTitle:@"分享" localizedSubtitle:nil icon:secondItemIcon userInfo:nil];

    application.shortcutItems = @[firstItem,secondItem];

    return YES;
}

2.实现这个方法-(void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler 在这个方法中处理添加和分享的事件，代码如下：

-(void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler{

    if ([shortcutItem.type isEqual:@"add"]) {
    
         NSLog(@"执行添加事件");

    }else if([shortcutItem.type isEqual:@"share"]){
    
        NSLog(@"执行分享的操作 ");
    
    }
}

二、通过模拟器进行调试
使用SBShortcutMenuSimulator来配置模拟器，使模拟器支持3D Touch

• 在终端中按顺序输入以下命令：

1.git clone https://github.com/DeskConnect/SBShortcutMenuSimulator.git

2.cd SBShortcutMenuSimulator

3.make

• 然后打开刚才写好的程序 运行一下打开模拟器，再去终端中按顺序输入一下命令：

1.xcrun simctl spawn booted launchctl debug system/com.apple.SpringBoard --environment DYLD_INSERT_LIBRARIES=$PWD/SBShortcutMenuSimulator.dylib

2.xcrun simctl spawn booted launchctl stop com.apple.SpringBoard

3.echo 'com.apple.mobilecal' | nc 127.0.0.1 8000
**注意: 'com.apple.mobilecal' ''里边写的是自己项目的Bundle identifier. **
**这行命令就是要让模拟器显示出3D Touch，每次想要显示快速入口只要重复操作即可 **

三、现在看一下效果：
