saveWebViewAsPdf doesn't generate the PDF

[Isuru-Nanayakkara]

I tried this first in a Swift project. I added the library via CocoaPods.

platform :ios, '8.0'
use_frameworks!

pod 'BNHtmlPdfKit', :git => 'https://github.com/brentnycum/BNHtmlPdfKit'

Here's the code.

var htmlPdfKit: BNHtmlPdfKit!

override func viewDidLoad() {
    super.viewDidLoad()

    webView.loadRequest(NSURLRequest(URL: NSURL(string: "https://www.google.com/")!))
}

@IBAction func saveButtonTapped(sender: UIBarButtonItem) {
    let documentsDirectoryPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first!
    let documentsDirectoryPathURL = NSURL(string: documentsDirectoryPath)!
    let pdfPath = documentsDirectoryPathURL.URLByAppendingPathComponent("Google.pdf")
    print(pdfPath.absoluteString)

    htmlPdfKit = BNHtmlPdfKit()
    htmlPdfKit.delegate = self
    htmlPdfKit.pageSize = BNPageSizeA4
    htmlPdfKit.saveWebViewAsPdf(webView, toFile: pdfPath.absoluteString)
}

When the save button is tapped, the PDF isn't generated. Nor any of the BNHtmlPdfKitDelegate methods get called.

However other methods like saveUrlAsPdf and saveHtmlAsPdf do work. I tested this in Xcode 7.1 with iOS 8.4 and iOS 9.1 simulators.

I've uploaded a demo project too.

Later I tested this in a Objective-C project as well. And it didn't work either. So I guess this isn't a language issue.

@Isuru-Nanayakkara did you get to fix it?

[Isuru-Nanayakkara]

@vinbhai4u Nope, I had to resort to saving via a HTML string.

[vin-the-dev]

@Isuru-Nanayakkara even that doesn't work for me,

generateBNHtmlPDF(){
let pdfKit = BNHtmlPdfKit()
pdfKit.delegate = self
let toFile = Path.documentsDir["file.pdf"].path_string
let htmlString = Path.documentsDir["BSM.html"].readString()
pdfKit.saveHtmlAsPdf(htmlString, toFile: toFile)
print("open " + toFile)
}

is there something wrong?

i also can not generate pdf from an webView, follow the code, i add the save method in the - (void)saveWebViewAsPdf:(UIWebView *)webView toFile:(NSString *)file;
And it work now. i am not sure if this is correct ,but the doc has no use case on this .

-(void)saveWebViewAsPdf:(UIWebView *)webView toFile:(NSString *)file {
[[self class] cancelPreviousPerformRequestsWithTarget:self selector:@selector(_timeout) object:nil];
self.outputFile = file;
webView.delegate = self;
self.webView = webView;
//add for test
[self _savePdf];
}

Hey, I have solved the issue while generating pdf file from webview --saveWebViewAsPdf(webView, toFile: pdfPath.absoluteString) and now delegates are being called properly with the path of saved pdf file.

Actually I have done my changes after forking the project. Infact I have make a test project for this but unfortunately I don't know how to push my changes.
