iOS开发 解决WKWebView加载的h5，调用拨打电话功能

h5的拨打电话代码是

a href="tel:13112345678 

移动WEB页面JS一键拨打号码咨询功能UIWebView加载的h5，可以调用；但是WKWebView就是不行，找了半天，最后解决，在WKWebView的WKNavigationDelegate代理方法处理，

代码如下：/ 处理拨打电话以及Url跳转等等 

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {

NSURL *URL = navigationAction.request.URL;

NSString *scheme = [URL scheme];

if ([scheme isEqualToString:@"tel"]) {

NSString *resourceSpecifier = [URL resourceSpecifier];

NSString *callPhone = [NSString stringWithFormat:@"telprompt://%@", resourceSpecifier];

/// 防止iOS 10及其之后，拨打电话系统弹出框延迟出现

dispatch_async(dispatch_get_global_queue(0, 0), ^{

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]];

});

}

decisionHandler(WKNavigationActionPolicyAllow);

}
