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:,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.gitcd SBShortcutMenuSimulatormake复制代码
2.让SpringBoard支持SBShortcutMenuSimulator
xcrun simctl spawn booted launchctl debug system/com.apple.SpringBoard --environment DYLD_INSERT_LIBRARIES=$PWD/SBShortcutMenuSimulator.dylibxcrun simctl spawn booted launchctl stop com.apple.SpringBoard复制代码
3.预览:
echo 'com.apple.mobilecal' | nc 127.0.0.1 8000复制代码
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
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;}复制代码
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"); }}复制代码
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:
###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"); }}复制代码
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"); }}复制代码
###实现UIViewControllerPreviewingDelegate的代理方法:
#pragma mark - viewcontrollerPrewingdelegate//Peek 代理方法:- (UIViewController *)previewingContext:(id)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" bundle:nil]; peekVC.preferredContentSize = CGSizeMake(0, 0); return peekVC; }}//Pop 代理方法:- (void)previewingContext:(id )previewingContext commitViewController:(UIViewController *)viewControllerToCommit{ PeekViewController *peekVC = [[PeekViewController alloc] initWithNibName:@"PeekViewController" bundle:nil]; peekVC.sendData = @"from POP"; [self presentViewController:peekVC animated:YES completion:nil]; }复制代码
你可能见过类似的效果:
那么底下的这些选项又是怎么实现的呢?这个呢,需要在目标控制器里设置,也就是说,如果你的A控制器实现了上面的代理方法,然后想跳到B控制器,那么这些选项的设置就要在B控制器里通过UIPreviewAction来设置。//初始化preViewActionsItems- (NSArray> *)previewActionItems{ UIPreviewAction *action0 = [UIPreviewAction actionWithTitle:@"取消关注" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) { NSLog(@"取消关注"); }]; UIPreviewAction *action1 = [UIPreviewAction actionWithTitle:@"删除" style:UIPreviewActionStyleDestructive handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) { NSLog(@"删除"); }]; NSArray *previewActionItemsArray = @[action0,action1]; return previewActionItemsArray;}复制代码
OK~终于大功告成了。
