Ios PDFView无法移动到下一页
代码:Ios PDFView无法移动到下一页,ios,swift,pdf,ios-pdfkit,Ios,Swift,Pdf,Ios Pdfkit,代码: 我尝试在应用程序中显示pdf文件。它工作正常。如何实现水平滚动(逐页)和搜索功能(如突出显示搜索词)。将显示任何帮助。提前感谢您需要添加这行代码: if let path = Bundle.main.path(forResource: "test", ofType: "pdf") { let url = URL(fileURLWithPath: path) if let pdfDocument = PDFDocument(url: url)

if let path = Bundle.main.path(forResource: "test", ofType: "pdf") {
let url = URL(fileURLWithPath: path)
if let pdfDocument = PDFDocument(url: url) {
pdfView.displayMode = .singlePage
pdfView.autoScales = true
pdfView.displayDirection = .horizontal
pdfView.document = pdfDocument
}
}
****更新**
。有一些关于搜索的通知。请看。尝试使用此代码搜索字符串。在这一行中,可以设置beginFindString
pdfView.usePageViewController(true, withViewOptions: nil)
谢谢,它工作正常。对不起,我没有足够的声誉来支持你。对搜索功能有什么想法?你说的搜索功能是什么意思?比如移动到特定页面或突出显示匹配的单词,比如word Document这里是什么searchedItem?将searchedItem更改为SearchedStringDocumentDiEndDocument,documentDidFindMatch方法未被调用PLS委托您的PDFviewned设置pdfview.delegate=self?
var searchedString: PDFSelection?
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
self.document?.beginFindString("StringName", withOptions: .caseInsensitive)
}
func documentDidEndDocumentFind(_ notification: Notification) {
pdfView.setCurrentSelection(searchedString, animate: true)
}
func documentDidFindMatch(_ notification: Notification) {
if let selection = notification.userInfo?.first?.value as? PDFSelection {
selection.color = .Red
if searchedString == nil {
// The first found item sets the object.
searchedString = selection
} else {
// All other found selection will be nested
searchedString!.add(selection)
}
}
}
