我在从iOS分享图片到小程序的时候，会跳转两次。第一次是链接小程序的界面（如图），load结束后会跳回App，然后又自动跳回微信才是成功的分享图片界面，请问是什么情况？

背景如下：

1. app是有关联小程序的，也执行过WXApi 下面这个方法了；

   + (BOOL)registerApp:(NSString *)appid universalLink:(NSString *)universalLink;

2. 小程序只发布了体验版，正式版尚未发布；

3. 分享图片的时候代码如下：

   + (void)shareImageWithWeChatWithType:(int)scene                                image:(UIImage *)image                           completion:(void (^ __nullable)(BOOL success))completion {     if ([WXApi isWXAppInstalled] && [WXApi isWXAppSupportApi]) {         // 压缩图片小于10M         NSData * imageData = UIImageJPEGRepresentation([SZUtils compressImage:image toByte:10485760], 0.7);         WXImageObject *imageObject = [WXImageObject object];         imageObject.imageData = imageData;         WXMediaMessage *message = [WXMediaMessage message];          // 压缩图片小于32kb         [message setThumbImage:[SZUtils compressImage:image toByte:32768]];         message.mediaObject = imageObject;         SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];         req.bText = NO;         req.message = message;         req.scene = scene;         [WXApi sendReq:req completion:^(BOOL success){             completion(success);         }];     } else {         [SZUtils showAlert:@"请安装微信" okBtn:@"确定" result:^(NSInteger index) {                       }];     } }
