蘋果在iPhone6s和iPhone6s Plus中加入了3D Touch技術(shù)茸时，其實Apple Watch的屏幕上很早就用到這一技術(shù)了符隙，并不新穎，由于本人剛買的iPhone6s下硕，所以試玩一下砰左。沒有6S和6SP的小伙伴也不要抱怨，好東西來了：SBShortcutMenuSimulator,能讓模擬器支持HomeScreen Quick Action睡榆。趕緊去嘗試吧~

SBShortcutMenuSimulator

1.編譯：在終端依次輸入下面的命令

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

cd SBShortcutMenuSimulator

make

2.讓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.預(yù)覽：

echo 'com.apple.mobilecal' | nc 127.0.0.1 8000

注意：'com.apple.mobilecal' 是系統(tǒng)自帶日歷的BundleID萍肆，記得要換成自己的喔~

Home Screen Quick Action

預(yù)覽圖1.png

- (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;
}

響應(yīng)回調(diào)：

- (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");
    }
}

特別注意：
**1.每個APP最大支持4個Action Item；
2.靜態(tài)動態(tài)同時設(shè)置的時候宿崭，不會覆蓋亲铡；

UIKit Peek & Pop

短時間按壓屏幕可以實現(xiàn)預(yù)覽，這就是peek葡兑，再用力按壓奖蔓，直接進(jìn)到另一個頁面，就是Pop了讹堤。要實現(xiàn)Peek和Pop功能吆鹤，首先要判斷設(shè)備是否支持3D Touch功能，然后遵守UIViewControllerPreviewingDelegate洲守，并實現(xiàn)它僅有的兩個方法：

監(jiān)測3D Touch:

我們可以在viewWillAppear方法里檢測：

- (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 未檢測");
    }
}

如果程序內(nèi)修改了3D Touch設(shè)置疑务，我們通過traitCollectionDidChange來檢測：

//生命周期內(nèi)可以通過這個方法重新檢測3D Touch功能
- (void)traitCollectionDidChange:(UITraitCollection *)previousTraitCollection
{
    if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {
        //功能可用的情況下進(jìn)行注冊
        [self registerForPreviewingWithDelegate:self sourceView:self.tableView];
        NSLog(@"已注冊");
    }else{
        NSLog(@"沒注冊");
    }
}

實現(xiàn)UIViewControllerPreviewingDelegate的代理方法：

#pragma mark - viewcontrollerPrewingdelegate
//Peek 代理方法：
- (UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location
{
    //防止重復(fù)彈出
    if ([self.presentationController isKindOfClass:[PeekViewController class]]) {
        return nil;
    }else{
        //找到正在按壓的cell，從而著重顯示梗醇，
        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" bundle:nil];
        peekVC.preferredContentSize = CGSizeMake(0, 0);
        return peekVC;
    }
}
//Pop 代理方法：
- (void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit
{
    PeekViewController *peekVC = [[PeekViewController alloc] initWithNibName:@"PeekViewController" bundle:nil];
    peekVC.sendData = @"from POP";
    [self presentViewController:peekVC animated:YES completion:nil];   
}

你可能見過類似的效果:

那么底下的這些選項又是怎么實現(xiàn)的呢知允？這個呢，需要在目標(biāo)控制器里設(shè)置叙谨，也就是說温鸽，如果你的A控制器實現(xiàn)了上面的代理方法，然后想跳到B控制器手负，那么這些選項的設(shè)置就要在B控制器里通過UIPreviewAction來設(shè)置涤垫。

//初始化preViewActionsItems
- (NSArray<id<UIPreviewActionItem>> *)previewActionItems
{
    UIPreviewAction *action0 = [UIPreviewAction actionWithTitle:@"取消關(guān)注" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
        NSLog(@"取消關(guān)注");
    }];
    UIPreviewAction *action1 = [UIPreviewAction actionWithTitle:@"刪除" style:UIPreviewActionStyleDestructive handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
        NSLog(@"刪除");
    }];
    NSArray *previewActionItemsArray = @[action0,action1];
    return previewActionItemsArray;
}

OK~終于大功告成了。
