WKWebView出于安全性考虑, 对于打开外部链接 应用等操作进行了拦截
WKWebView打开外部应用, Safari等
设置代理
_webView.navigationDelegate = self;
手动打开拦截
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler{
// WKWebView默认拦截scheme 需在下面方法手动打开
// 打开外部应用 Safari等操作
if ([navigationAction.request.URL.absoluteString hasPrefix:@"xxx"]) { // 对应的scheme
[[UIApplication sharedApplication] openURL:navigationAction.request.URL];
}
decisionHandler(WKNavigationActionPolicyAllow);
}
WKWebView替换JS alert confirm等
设置代理
_webView.UIDelegate = self;
拦截JS alert
- (void)webView:(WKWebView *)webView runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WKFrameInfo *)frame completionHandler:(void (^)(void))completionHandler{
// WKWebView不支持JS的alert 用此方法进行拦截
// message为JS中alert显示的信息 可与前端开发约定好信息
if ([message isEqualToString:@"xxx"]) {
// 做OC操作
}
completionHandler();
}
拦截JS confirm
- (void)webView:(WKWebView *)webView runJavaScriptConfirmPanelWithMessage:(NSString *)message initiatedByFrame:(WKFrameInfo *)frame completionHandler:(void (^)(BOOL result))completionHandler{
// 类比alert 拦截JS confirm
completionHandler(NO);
}
