摘要：
虽然3DTouch已经推出了很长时间，但该项目最近才接触到它，所以我已经整理并记录了我实现的代码。
尽管3DTouch已经出来很久，但是项目最近才接触到，所以就整理了一下自己实现的代码，记录。
1.实现重按app，弹出窗口（如图所示）
在
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中实现：
//添加3dtouch
//动态加载自定义的ShortcutItem
if (application.shortcutItems.count == 0) {
UIMutableApplicationShortcutItem *itemScan = [[UIMutableApplicationShortcutItem alloc]initWithType:@"Scan" localizedTitle:@"扫一扫" localizedSubtitle:nil icon:[UIApplicationShortcutIcon iconWithTemplateImageName:@"icon2"] userInfo:nil];
UIMutableApplicationShortcutItem *itemWrite = [[UIMutableApplicationShortcutItem alloc]initWithType:@"listen" localizedTitle:@"去写作" localizedSubtitle:nil icon:[UIApplicationShortcutIcon iconWithTemplateImageName:@"icon1"] userInfo:nil];
application.shortcutItems = @[itemScan,itemListen];
}
/*ps：about icon
[UIApplicationShortcutIcon iconWithTemplateImageName:@"icon1"]//这是替换自己的图片
[UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeCompose];//这是系统内的特定icon*/
随后实现：
-(void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void(^)(BOOL succeeded))completionHandler；
在该方法中，可以通过判断唯一标示符（之前设置的initwithtype：）或者判断localizedTitle来区别点击的哪一行
而后可以使用通知或者直接导航等等跳转到你想要去的界面，这里就不细说了。
2.重按cell的3DTouch效果
实现
UIViewControllerPreviewingDelegate代理方法
- (void)viewDidLoad { [self registerPreview]; } -(void)registerPreview{ //判断是否支持3dtouch，设置委托代理 if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) { [self registerForPreviewingWithDelegate:self sourceView:self.tableView]; } else { NSLog(@"该设备不支持3D-Touch"); } } #pragma mark - UIViewControllerPreviewingDelegate - (nullable UIViewController *)previewingContext:(id <UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location { NSIndexPath * indexPath =[_tableView indexPathForRowAtPoint:location]; UITableViewCell * cell = [_tableView cellForRowAtIndexPath:indexPath]; //以上得到你点击的哪一行的cell if (!cell) { return nil; } //显示3dtouchpreviewViewcontroller界面 3DTouchPreviewViewController *detailVC =[[3DTouchPreviewViewController alloc]init]; detailVC.preferredContentSize = CGSizeMake(0, 0); previewingContext.sourceRect = cell.frame; return detailVC; } - (void)previewingContext:(id <UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit { [self.navigationController pushViewController:viewControllerToCommit animated:NO]; }
在3dtouchpreviewViewController.m中实现：
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor =[UIColor whiteColor];
//你所想要显示的东西
UILabel *textlabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 40)];
textlabel.backgroundColor = [UIColor colorWithRed:54/255.0 green:54/255.0 blue:54/255.0 alpha:1];
textlabel.textColor = [UIColor whiteColor];
textlabel.text = @"哈哈哈哈哈哈";
textlabel.textAlignment = NSTextAlignmentCenter;
textlabel.font = [UIFont fontWithName:@"STHeitiSC-Light" size:16];
[self.view addSubview:textlabel];
_imageViewShow =[[UIImageView alloc]init];
_imageViewShow.frame = CGRectMake(0, 40, self.view.bounds.size.width, self.view.bounds.size.height-40);
_imageViewShow.image = [UIImage imageNamed:@"picture"];
[self.view addSubview:_imageViewShow];
}
//下面的actionview
- (NSArray <id <UIPreviewActionItem>> *)previewActionItems
{
UIPreviewAction *action = [UIPreviewAction actionWithTitle:@"删除" style: UIPreviewActionStyleDestructive handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
NSLog(@"实现删除功能！");
}];
return @[action];
}
以上就是3DTouch的简单使用，如有不足之处，欢迎指出。
