如何使用Swift将带有pdf的webview页面加载到ibooks中

这是我能找到的最接近的代码，但没有使用包含pdf文件的webview页面的语法

var docController:UIDocumentInteractionController

如果let path=NSBundle.mainBundle（）.pathForResource（“book”，类型为“pdf”）{ 如果让targetURL=NSURL.fileURLWithPath（路径）{

在ibooks中打开之前，您发现需要将pdf文件写入设备。以下是有效的代码：

func downloadPDF() {
    // Running operations that takes a long time in a background thread is recommended
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), { () -> Void in
        // Get the PDF data from the URL
        let url = self.webview.request?.URL
        let pdfURL = url?.absoluteString
        let pdfData = NSData(contentsOfURL: NSURL(string: pdfURL!)!)!

        // Store the data locally as a PDF file in the Documents directory
        let documentsDirPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first as! String
        localPdfPath = documentsDirPath.stringByAppendingPathComponent(pdfURL!.lastPathComponent)
        pdfData.writeToFile(localPdfPath, atomically: true)

        // UI related stuff should be called in the main thread.
        dispatch_async(dispatch_get_main_queue(), { () -> Void in
            self.openIniBooks()
            IJProgressView.shared.hideProgressView()
        })
    })
}

我高估了你的票数，因为这是一个措辞得体的问题，我也在寻找这个问题的答案，但一直找不到。如果我遇到任何问题，我会把它放在这里。我高估了你的票数，因为这是一个措辞得体的问题，我也在寻找这个问题的答案，但一直找不到。如果我遇到任何问题，我会把它放在这里重新。
