我也是微信登录不回调，这个方法也实现了，打印的日志是 WXLog = wxlog:set property list WXLog = wxlog:Error:fail to load Keychain status:-25300, keyData null:1 WXLog = wxlog:Error:token[(null)] is null WXLog = wxlog:launch app with ul only success WXLog = wxlog:launch app with universal link, ret:1 WXLog = wxlog:req:, cid:62b00cbe1f760b0fae06972120fe968160f0c400 PBItemCollectionServicer connection disconnected. Can't end BackgroundTask: no background task exists with identifier 1 (0x1), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.
参考下这个回复：ios sdk 1.8.6.1 授权登录没有回调 onResp ？? AIZEN 的回答 - 微信开放社区 https://developers.weixin.qq.com/community/develop/doc/000a84d6f444b8ade84942a475b400?highLine=onResp&jumpto=comment&commentid=000e6a31b34f200eeb49534de5b8
