[WebView] Error trying to display PDF in web view component

Hello,

I am trying to display a pdf file from the app bundle but I could not do it, this is what I have done:

            <WebView
                startInLoadingState={true}
                style={styles.web}
                url={"localFile.pdf"}
                />

localFile.pdf is obviously included in the bundle but when I try to display this webview it doesn’t show it properly.

From xcode I have got these error messages:

[85869:8794860] DiskImageCache: Could not resolve the absolute path of the old directory. [85869] <Error>: CGAffineTransformInvert: singular matrix. [85869] <Error>: CGAffineTransformInvert: singular matrix. [85869] <Error>: CGAffineTransformInvert: singular matrix.

And I can’t see it

 <WebView
                startInLoadingState={true}
                style={styles.web}
                url={"localFile.pdf"}
                /> 

Removing the startInLoadingState={true} line fixes the issue. The pdf gets displayed

TEMPORARY SOLUTION:

I have modified the class RCTWebView and method initWithEventDispatcher to have something like this:

- (instancetype)initWithEventDispatcher:(RCTEventDispatcher *)eventDispatcher
{
  RCTAssertParam(eventDispatcher);

  if ((self = [super initWithFrame:CGRectZero])) {
    super.backgroundColor = [UIColor clearColor];
    _automaticallyAdjustContentInsets = YES;
    _contentInset = UIEdgeInsetsZero;
    _eventDispatcher = eventDispatcher;
    _webView = [[UIWebView alloc] initWithFrame:[[UIScreen mainScreen]bounds]];
    _webView.delegate = self;
    [self addSubview:_webView];
  }
  return self;
}

the key to solve the problem it has been the line:

_webView = [[UIWebView alloc] initWithFrame:[[UIScreen mainScreen]bounds]];

previously it was something like this:

_webView = [[UIWebView alloc] initWithFrame:self.bounds];

I guess there is some issue getting the bounds of the webview, that’s why I have specified the main screen bounds.
