同样的脚本在 iOS 11.3 和ios 11 转换出来的代码不一样

[xiaodai]

OC 方法
-(void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler
{
NSURL *url = navigationAction.request.URL;
if ([url.scheme isEqualToString:@"weixin"] || [url.scheme isEqualToString:@"alipay"]) {
if ( [[UIApplication sharedApplication] canOpenURL:url]) {
if (@available(iOS 10.0, *)) {
[[UIApplication sharedApplication] openURL:url options:@{UIApplicationOpenURLOptionUniversalLinksOnly: @no} completionHandler:nil];
} else {
[[UIApplication sharedApplication] openURL:url];
}
decisionHandler(WKNavigationActionPolicyCancel);
return;
}
}
decisionHandler(WKNavigationActionPolicyAllow);
}

脚本如下
defineClass("LYWebViewController", {
webView_decidePolicyForNavigationAction_decisionHandler: function (webView, navigationAction,decisionHandler) {
var url = navigationAction.request().URL();
if (url.scheme().isEqualToString("weixin") || url.scheme().isEqualToString("alipay")) {
if (UIApplication.sharedApplication().canOpenURL(url)) {
if (UIDevice.currentDevice().systemVersion().floatValue() >= 10) {
UIApplication.sharedApplication().openURL_options_completionHandler(url, {
UIApplicationOpenURLOptionUniversalLinksOnly: NO
}, null);
} else {
UIApplication.sharedApplication().openURL(url);
}
decisionHandler(0);
return;
}
}
decisionHandler(1);
}
}, {});

ios 11 正常执行，ios 11.3 脚本报错，说decisionHandler不是函数，是个object

我也遇到了相同的问题 请问解决了吗

试试

if (typeof decisionHandler == 'function') {
decisionHandler(0);
}
if (typeof decisionHandler == 'function') {
decisionHandler(1);
}
