crash on iOS10.3

[jinjuezhou]

hi,
I have receive crash Completion handler passed to -[WKWebViewJavascriptBridge webView:decidePolicyForNavigationAction:decisionHandler:] was called more than once
only on iOS10.3

[summerdev10]

I'm getting this too, any ideas for a workaround?

The crash is in simulator,not present in iPhone.
in WKWebViewJavascriptBridge.m, modify like this (comment with add this)

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
    if (webView != _webView) { return; }
    NSURL *url = navigationAction.request.URL;
    __strong typeof(_webViewDelegate) strongDelegate = _webViewDelegate;

    if ([_base isWebViewJavascriptBridgeURL:url]) {
        if ([_base isBridgeLoadedURL:url]) {
            [_base injectJavascriptFile];
        } else if ([_base isQueueMessageURL:url]) {
            [self WKFlushMessageQueue];
        } else {
            [_base logUnkownMessage:url];
        }
        decisionHandler(WKNavigationActionPolicyCancel);
        return; // add This
    }
    
    if (strongDelegate && [strongDelegate respondsToSelector:@selector(webView:decidePolicyForNavigationAction:decisionHandler:)]) {
        [_webViewDelegate webView:webView decidePolicyForNavigationAction:navigationAction decisionHandler:decisionHandler];
    } else {
        decisionHandler(WKNavigationActionPolicyAllow);
    }
}

@mengxiangyue Did you pull request for this issue?

[darvintang]

什么时候能解决这个问题？修改源码就不能用pod管理了，痛苦。

[mengxiangyue]

我没有用pod，因为我也添加了 原生调用js 不存在的方法 返回9999的能力，另外添加了白名单功能
