3DTouch那点事
公司之前在新的版本中添加了3DTouch,今天就总结出来方面大家参考和查阅
一、3D Touch 的Quick Action实现
Quick Action有两种方式:静态和动态,静态是在plist文件中申明,动态则是在代码中注册,系统支持两者同时存在。但是系统限制每个app最多显示4个快捷图标,包括静态和动态。
第一种方式动态添加入口标签
-(BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
方法中实现添加和分享的入口,代码如下 :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// 创建标签的ICON图标。
UIApplicationShortcutIcon *firstItemIcon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeAdd];
// 创建一个标签,并配置相关属性。
UIMutableApplicationShortcutItem *firstItem = [[UIMutableApplicationShortcutItem alloc]initWithType:@"First" localizedTitle:@"添加" localizedSubtitle:nil icon:firstItemIcon userInfo:nil];
UIApplicationShortcutIcon *secondItemIcon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeShare];
UIMutableApplicationShortcutItem *secondItem = [[UIMutableApplicationShortcutItem alloc]initWithType:@"Second" localizedTitle:@"分享" localizedSubtitle:nil icon:secondItemIcon userInfo:nil];
// 自定义创建标签的ICON图标。
UIApplicationShortcutIcon *thirdItemIcon = [UIApplicationShortcutIcon iconWithTemplateImageName:@""];
UIMutableApplicationShortcutItem *thirdItem = [[UIMutableApplicationShortcutItem alloc]initWithType:@"Third" localizedTitle:@"自定义" localizedSubtitle:nil icon:thirdItemIcon userInfo:nil];
application.shortcutItems = @[firstItem,secondItem,thirdItem];
return YES;
}
系统提供的图标样式
typedef NS_ENUM(NSInteger, UIApplicationShortcutIconType) { UIApplicationShortcutIconTypeCompose,
UIApplicationShortcutIconTypePlay,
UIApplicationShortcutIconTypePause,
UIApplicationShortcutIconTypeAdd,
UIApplicationShortcutIconTypeLocation,
UIApplicationShortcutIconTypeSearch,
UIApplicationShortcutIconTypeShare,
UIApplicationShortcutIconTypeProhibit NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeContact NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeHome NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeMarkLocation NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeFavorite NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeLove NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeCloud NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeInvitation NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeConfirmation NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeMail NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeMessage NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeDate NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeTime NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeCapturePhoto NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeCaptureVideo NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeTask NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeTaskCompleted NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeAlarm NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeBookmark NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeShuffle NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeAudio NS_ENUM_AVAILABLE_IOS(9_1),
UIApplicationShortcutIconTypeUpdate NS_ENUM_AVAILABLE_IOS(9_1)
}
NS_ENUM_AVAILABLE_IOS(9_0) __TVOS_PROHIBITED;
2.实现这个方法
-(void)application:(UIApplication *)application performActionForShortcutItem:
(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
在这个方法中处理添加和分享的事件,代码如下:
-(void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
{
if ([shortcutItem.type isEqual:@"add"])
{ NSLog(@"执行添加事件"); }
else if([shortcutItem.type isEqual:@"share"])
{ NSLog(@"执行分享的操作 ");}
}
第二种方式静态添加入口标签
静态添加入口标签不需要写代码,只需要在info.plist文件中添加相关功能设置即可。
静态的方法加入:
即在plist文件中加入UIApplicationShortcutItems标签,标签类型为NSArray,根据需要可以添加四个不同的子标签。类型为NSDictionary。然后加如所需键值对:
必填项(下面两个键值是必须设置的):
UIApplicationShortcutItemType 这个键值设置一个快捷通道类型的字符串
UIApplicationShortcutItemTitle 这个键值设置标签的标题
选填项(下面这些键值不是必须设置的):
UIApplicationShortcutItemsUIApplicationShortcutItemSubtitle 设置标签的副标题
UIApplicationShortcutItemIconType 设置标签的图标样式,系统提供了29中样式的图标
UIApplicationShortcutItemIconFile 设置自定义标签图片文件的路径
UIApplicationShortcutItemUserInfo 设置用户信息,是一个字典类型,可以用来传值
<key>UIApplicationShortcutItems</key>
<array>
<dict>
<key>UIApplicationShortcutItemType</key>
<string>First</string>
<key>UIApplicationShortcutItemTitle</key>
<string>添加</string>
<key>UIApplicationShortcutItemIconType</key>
<string>UIApplicationShortcutIconTypeFavorite</string>
<string>UIApplicationShortcutIconTypeShare</string>
</dict>
<dict>
<key>UIApplicationShortcutItemType</key>
<string>Second</string>
<key>UIApplicationShortcutItemTitle</key>
<string>帅哥</string>
<key>UIApplicationShortcutItemIconType</key>
<string>UIApplicationShortcutIconTypeFavorite</string>
</dict>
</array>

二、3D Touch 的Peek和Pop实现
3D Touch 的Peek和Pop实现使用步骤:
- 给Cell注册3DTouch
- 遵守协议<UIViewControllerPreviewingDelegate>
- 实现协议方法
第1步:给Cell注册3DTouch
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
MyTableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:@"zhan" forIndexPath:indexPath];
//判断是否支持3DTouch
if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {
//注册Cell支持3DTouch,并设置代理
[self registerForPreviewingWithDelegate:self sourceView:cell];
}
return cell;
}
第2步:遵守协议<UIViewControllerPreviewingDelegate>
@interface ViewController ()<UITableViewDelegate,UITableViewDataSource,UIViewControllerPreviewingDelegate>
@property (weak, nonatomic) IBOutlet UITableView *myTableView;
第3步:实现协议方法
-(UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location
{
//获取sourceView
MyTableViewCell *cell = (MyTableViewCell *)[previewingContext sourceView];
//设置弹出预览的位置(peek是从哪个位置弹出)
[previewingContext setSourceRect:cell.bounds];
//设置弹框的View.
UIStoryboard *sb=[UIStoryboard storyboardWithName:@"Main" bundle:nil];
DetailViewController *detailVC = [sb instantiateViewControllerWithIdentifier:@"DetailViewController"];
//设置弹出peek的高度(设置宽度是没有效果的)
detailVC.preferredContentSize = CGSizeMake(0, self.view.bounds.size.height*0.6);
//取出Cell的模型传递给详情控制器.
return detailVC;
//设置标题
//detailVC.title = @"帅";
//在这里想弹一个带有导航条的控制器,控制器里面包装一个导航条.直接返回导航控制器.那么就会peek出一个导航控制器.
//return [[UINavigationController alloc] initWithRootViewController:detailVC];
}

弹框出现后,继续重按时调用
//弹框出现后,继续重按时调用 //viewControllerToCommit:就是上面return的控制器.
- (void)previewingContext:(id <UIViewControllerPreviewing>)previewingContext commitViewController:(UINavigationController *)viewControllerToCommit{
//*******如果上面返回的是导航控制器*********
//获取导航控制器的根控制器.因为当前已经是一个导航控制器了,不能再继续push一个导航控制器,所以要先获取peek的导航控制器里面的根控制器.
//然后再拿当前的控制器把获取的控制器push进去.
//DetailViewController *detailVC = (DetailViewController*)viewControllerToCommit.childViewControllers.lastObject;
//*******如果上面返回的是导航控制器*********
DetailViewController *detailVC = (DetailViewController*)viewControllerToCommit;//.childViewControllers.lastObject;
[self.navigationController pushViewController:detailVC animated:YES];
//使用show和push是一样的效果
//[self showViewController:viewControllerToCommit sender:self];
弹窗出现后,向上滑动,会出现类似ActionSheet的控件.
实现该效果必须得要是在previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location return回去那个控制器当中实现以下方法,(我们这里peek出来的是DetailViewController,所以必须得要在DetailViewController中实现该方法)
-(NSArray<id<UIPreviewActionItem>> *)previewActionItems
{
//弹出的第一个按钮
UIPreviewAction *action0 = [UIPreviewAction actionWithTitle:@"收藏" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
NSLog(@"收藏");
}];
UIPreviewAction *action1 = [UIPreviewAction actionWithTitle:@"点赞" style:UIPreviewActionStyleDestructive handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
NSLog(@"点赞");
}];
UIPreviewAction *action2 = [UIPreviewAction actionWithTitle:@"试试" style:UIPreviewActionStyleSelected handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
NSLog(@"试试");
}];
UIPreviewAction *action3 = [UIPreviewAction actionWithTitle:@"星星" style:UIPreviewActionStyleSelected handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
NSLog(@"星星");
}];
//该按钮可以是一个组,点击该组时,跳到组里面的按钮.
UIPreviewActionGroup *actionGroup = [UIPreviewActionGroup actionGroupWithTitle:@"组" style:UIPreviewActionStyleSelected actions:@[action2, action3]];
//直接返回数组.
return @[action0,action1,actionGroup];
}

三、通过模拟器进行调试
使用SBShortcutMenuSimulator来配置模拟器,使模拟器支持3D Touch
在终端中按顺序输入以下命令:
1.git clone https://github.com/DeskConnect/SBShortcutMenuSimulator.git
2.cd SBShortcutMenuSimulator
3.make
然后打开刚才写好的程序 运行一下打开模拟器,再去终端中按顺序输入一下命令:
1.xcrun simctl spawn booted launchctl debug system/com.apple.SpringBoard --environment DYLD_INSERT_LIBRARIES=$PWD/SBShortcutMenuSimulator.dylib
2.xcrun simctl spawn booted launchctl stop com.apple.SpringBoard
3.echo 'com.apple.mobilecal' | nc 127.0.0.1 8000
注意: 'com.apple.mobilecal' ''里边写的是自己项目的Bundle identifier. 这行命令就是要让模拟器显示出3D Touch,每次想要显示快速入口只要重复操作即可
echo 'com.zhanming.text.-DTouch-OC
' | nc 127.0.0.1 8000
具体代码放在了GitHub上大家可以下载。
