如果添加图标上的3d touch

则在appdelegate中添加如下代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // Override point for customization after application launch.

    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];

    

    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:[[BSTableViewController alloc] init]];

    

    self.window.rootViewController = nav;

    

    // 动态添加快捷启动

    UIApplicationShortcutIcon *icon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeAlarm];

    UIApplicationShortcutItem *item = [[UIApplicationShortcutItem alloc] initWithType:@"shortcutTypeTwo" localizedTitle:@"two" localizedSubtitle:nil icon:icon userInfo:nil];

    [[UIApplication sharedApplication] setShortcutItems:@[item]];

    

    

    [self.window makeKeyAndVisible];

    return YES;

}

这是新增添的方法
