据说苹果某个神秘的团队闭门潜心研发多年的3DTouch终于，应用在iOS9上，且公开了API。
在系统主界面用力按压 APP 图标，如上会出现自定义菜单
有两种方法可以实现
一.代码（这种方法也是可以动态的改变 3DTouch菜单的内容与功能）：
第一步：自定义一个初始化菜单的方法；
-(void)init3DTouch{
if ([[UIDevice currentDevice] systemVersion].floatValue < 9.0) {
return;
}
UIApplication *app = [UIApplication sharedApplication];
NSMutableArray *its = [[app shortcutItems] mutableCopy];
if (its.count == ) {
NSMutableArray *items = [[NSMutableArray alloc] init];
UIApplicationShortcutIcon *icon2 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeAdd];
UIApplicationShortcutItem *i2 = [[UIApplicationShortcutItem alloc] initWithType:@"com.xiaomi.i2" localizedTitle:@"发起群聊" localizedSubtitle:@"" icon:icon2 userInfo:nil];
[items addObject:i2];
UIApplicationShortcutIcon *icon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeShare];
UIApplicationShortcutItem *i1 = [[UIApplicationShortcutItem alloc] initWithType:@"com.xiaomi.i1" localizedTitle:@"电话会议" localizedSubtitle:@"" icon:icon userInfo:nil];
[items addObject:i1];
[app setShortcutItems:items];
}
}
第二步：实现 UIApplication 协议来响应系统主页按压APP出现菜单的，菜单对应点击事件；
-(void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler{
if ([shortcutItem.type isEqualToString:@"com.xiaomi.i1"]) {
// 点击菜单一 ‘发起群聊’ 执行的内容
}
else if ([shortcutItem.type isEqualToString:@"com.xiaomi.i2"]){
// 点击菜单二 ‘电话会议’ 执行的内容
}
}
// Called when the user activates your application by selecting a shortcut on the home screen,
// except when -application:willFinishLaunchingWithOptions: or -application:didFinishLaunchingWithOptions returns NO.
第三步：判断 launchOptions != nil 则返回NO；顺便获取激活APP的对象，手动执行所点击的菜单事件
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self init3DTouch];
// 当APP 不再后台运行时 通过3DTouch 激活APP，launchOptions不为空手动调用 performActionForShortcutItem
if ( launchOptions != nil ) {
UIApplicationShortcutItem *i = [launchOptions objectForKey: UIApplicationLaunchOptionsShortcutItemKey];
[self application:application performActionForShortcutItem:i completionHandler:^(BOOL succeeded) {
NSLog(@"launchOptions no null");
}];
return NO;
}
return YES;
}
二.info.plist
