微信SDK与Universal Links 的配置

新版微信分享 SDK要求必须使用Universal Links，所以 升级了一下工程，概要如下：
pod 'WechatOpenSDK', '~> 1.8.7.1'

1.Info.plist里

<string>wechat</string>
<string>weixin</string>
<string>weixinULAPI</string>

App.entitlements 以及AppDebug.entitlements
Targets=>Signing&Capabilities=>Release及
Targets=>Signing&Capabilities=>Debug

这里有个坑，配置了一个 All 后以为Debug和Release都有了，实际不是的，提交代码时才发现。

3. • (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
     里配置

[WXApi registerApp:AppKey universalLink:@"https://xxxxxxx"];

4.AppDelegate里添加如下代码

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
    return  [WXApi handleOpenURL:url delegate:self];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    return [WXApi handleOpenURL:url delegate:self];
}
- (BOOL)application:(UIApplication *)application
  continueUserActivity:(NSUserActivity *)userActivity
   restorationHandler:(nonnull void (^)  (NSArray<id<UIUserActivityRestoring>> * _Nullable))restorationHandler{
    return [WXApi handleOpenUniversalLink:userActivity
                             delegate:self];
}
