【Swift】SpotLight搜索
SpotLight主要功能是在iOS9系统界面下拉会出现搜索功能界面,在这里可以搜索关键信息,来展示应用内的内容,并且点击信息打开应用跳转具体页面等操作。这个功能还是很有用的,面对这越来越多的应用霸占你手机,给你的应用加上这么一个搜搜功能,还是有点与众不同,主要是提升逼格。
1、导入头文件
import CoreSpotlightimport MobileCoreServices
2、设置应用内搜索
func indexItem(title: String, desc: String, identifier: String) { let attributeSet = CSSearchableItemAttributeSet(itemContentType: kUTTypeText as String) attributeSet.title = title attributeSet.contentDescription = desc attributeSet.keywords = ["abc","cd","efg"] let item = CSSearchableItem(uniqueIdentifier: "\(identifier)", domainIdentifier: "Lingye.OopsVoice", attributeSet: attributeSet) CSSearchableIndex.default().indexSearchableItems([item]) { error in if let error = error { print("Indexing error: \(error.localizedDescription)") } else { print("Search item successfully indexed!") } } } func deindexItem(identifier: String) { CSSearchableIndex.default().deleteSearchableItems(withIdentifiers: ["\(identifier)"]) { error in if let error = error { print("Deindexing error: \(error.localizedDescription)") } else { print("Search item successfully removed!") } } }
3、在Appdelegate中实现SpotLight搜索
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool { if userActivity.activityType == CSSearchableItemActionType { if let uniqueIdentifier = userActivity.userInfo?[CSSearchableItemActivityIdentifier] as? String { deindexItem(identifier: uniqueIdentifier) } } return true }
