iOS WKWebView 跳转appStore或者拨号

WKWebView默认禁止了一些跳转

• UIWebView

打开ituns.apple.com跳转到appStore, 拨打电话, 唤起邮箱等一系列操作UIWebView默认支持的.

• WKWebView

默认禁止了以上行为,除此之外,js端通过window.open()打开新的网页的动作也被禁掉了.

如何支持呢?

// 可以跳转appStore或者拨号
-(void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
    if(webView != self.wkWebView) {
        decisionHandler(WKNavigationActionPolicyAllow);
        return;
    }
    UIApplication *app = [UIApplication sharedApplication];
    NSURL *url = navigationAction.request.URL;
    if ([url.scheme isEqualToString:@"tel"])
    {
        if ([app canOpenURL:url])
        {
            [app openURL:url];
            decisionHandler(WKNavigationActionPolicyCancel);
            return;
        }
    }
    if ([url.absoluteString containsString:@"ituns.apple.com"])
    {
        if ([app canOpenURL:url])
        {
            [app openURL:url];
            decisionHandler(WKNavigationActionPolicyCancel);
            return;
        }
    }
    decisionHandler(WKNavigationActionPolicyAllow);
}
