I’m assuming you’re using 

WKWebView
here. If you’re using one of our deprecated web views, there are equivalent techniques available but, rather than go into details, my recommendation is that you switch to 
WKWebView
first.

The standard way of implementing downloads in a web view is:

  1. Implement the 

    -webView:decidePolicyForNavigationAction:decisionHandler:
    delegate method.

  2. Have it look for PDFs.

  3. For non-PDFs, call the decision handler with 

    WKNavigationActionPolicyAllow
    .

  4. For PDFs, call the decision handler with 

    WKNavigationActionPolicyCancel
    and start the download via other means. For example, you might use an 
    NSURLSession
    background session to guarantee that the download continues even if your app is moved to the background.

Share and Enjoy
