苹果在iPhone6s和iPhone6s Plus中加入了3D Touch技术，其实Apple Watch的屏幕上很早就用到这一技术了，并不新颖，由于本人刚买的iPhone6s，所以试玩一下。没有6S和6SP的小伙伴也不要抱怨，好东西来了：
SBShortcutMenuSimulator
,能让模拟器支持HomeScreen Quick Action。赶紧去尝试吧~
##SBShortcutMenuSimulator
1.编译：在终端依次输入下面的命令
git clone https://github.com/DeskConnect/SBShortcutMenuSimulator.git
cd SBShortcutMenuSimulator
make
2.让SpringBoard支持SBShortcutMenuSimulator
xcrun simctl spawn booted launchctl debug system/com.apple.SpringBoard --environment DYLD_INSERT_LIBRARIES=$PWD/SBShortcutMenuSimulator.dylib
xcrun simctl spawn booted launchctl stop com.apple.SpringBoard
3.预览：
echo 'com.apple.mobilecal' | nc 127.0.0.1 8000
注意：'com.apple.mobilecal' 是系统自带日历的BundleID，记得要换成自己的喔~
##Home Screen Quick Action
![预览图1.png]()
创建Quick Action分为静态和动态两种方式：动态就是代码实现，但是程序要运行一次才会有效果；静态就是通过程序的Info.plist文件来设置。
动态实现的代码如下：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UIApplicationShortcutIcon *addIcon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeAdd];
UIApplicationShortcutIcon *shareIcon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeShare];
UIApplicationShortcutIcon *searchIcon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeSearch];
UIApplicationShortcutItem *item0 = [[UIApplicationShortcutItem alloc] initWithType:@"1" localizedTitle:@"添加" localizedSubtitle:nil icon:addIcon userInfo:nil];
UIApplicationShortcutItem *item1 = [[UIApplicationShortcutItem alloc] initWithType:@"2" localizedTitle:@"分享" localizedSubtitle:nil icon:shareIcon userInfo:nil];
UIApplicationShortcutItem *item2 = [[UIApplicationShortcutItem alloc] initWithType:@"3" localizedTitle:@"搜索" localizedSubtitle:nil icon:searchIcon userInfo:nil];
NSArray *itemArray = [NSArray arrayWithObjects:item0,item1,item2, nil];
[[UIApplication sharedApplication] setShortcutItems:itemArray];
return YES;
}
响应回调：
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
{
if ([shortcutItem.localizedTitle isEqualToString:@"1"]) {
NSLog(@"添加");
}else if ([shortcutItem.localizedTitle isEqualToString:@"2"]){
NSLog(@"分享");
}else if([shortcutItem.localizedTitle isEqualToString:@"3"]){
NSLog(@"搜索");
}
}
特别注意：
**1.每个APP最大支持4个Action Item；
2.静态动态同时设置的时候，不会覆盖；
**
##UIKit Peek & Pop
短时间按压屏幕可以实现预览，这就是peek，再用力按压，直接进到另一个页面，就是Pop了。要实现Peek和Pop功能，首先要判断设备是否支持3D Touch功能，然后遵守UIViewControllerPreviewingDelegate，并实现它仅有的两个方法：
![delegateMethods.png]()
###监测3D Touch:
我们可以在viewWillAppear方法里检测：
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {
NSLog(@"3D Touch 可用");
}else if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityUnavailable){
NSLog(@"3D Touch 不可用");
}else{
NSLog(@"3D Touch 未检测");
}
}
如果程序内修改了3D Touch设置，我们通过traitCollectionDidChange来检测：
//生命周期内可以通过这个方法重新检测3D Touch功能
- (void)traitCollectionDidChange:(UITraitCollection *)previousTraitCollection
{
if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {
//功能可用的情况下进行注册
[self registerForPreviewingWithDelegate:self sourceView:self.tableView];
NSLog(@"已注册");
}else{
NSLog(@"没注册");
}
}
###实现UIViewControllerPreviewingDelegate的代理方法：
//Peek 代理方法：
- (UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location
{
//防止重复弹出
if ([self.presentationController isKindOfClass:[PeekViewController class]]) {
return nil;
}else{
//找到正在按压的cell，从而着重显示，
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:location];
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
if (!cell) {
return nil;
}
previewingContext.sourceRect = cell.frame;
PeekViewController *peekVC = [[PeekViewController alloc] initWithNibName:@"PeekViewController"
