ios微信分享时报:"fail to load Keychain

在正确配置了ulink后，我们做微信分享发现出现微信链接界面之后，就会自动跳回自己的应用，如此往复，添加如下代码得到解决:
直接在AppDelegate中添加方法:

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void(^)(NSArray<id<UIUserActivityRestoring>> * __nullable restorableObjects))restorationHandler {
    return [WXApi handleOpenUniversalLink:userActivity delegate:self];
}
