Dropbox Sync API首先在iOS中同步 [英] Dropbox Sync api first Sync in iOS

问题描述

我使用了DropBox同步api来同步我的应用程序数据并从Dropbox导入图像。现在，我为 FileSystem 写了一个观察者。我的帐户可以正常使用，但不能与其他帐户一起使用。没有出现任何错误。 addObserver：self forPathAndChildren：[DBPath根]块：^ 没有被调用。

  if（！[DBAccountManager sharedManager] .linkedAccount.linked）
 {
 [[DBAccountManager sharedManager] linkFromController：self]; 
} 
 else 
 {
 if（！dbFileSys）
 {
 dbFileSys = [DBFilesystem sharedFilesystem]; 
} 
 __weak id weakSelf = self; 
 [dbFileSys addObserver：self forPathAndChildren：[DBPath根目录]块：^ 
 {
 [weakSelf loadFiles]; //加载文件
}]; 
 
} 
  

该观察员打来了我的帐户。

解决方案

观察者看起来还不错。我假设它是在您对目标Dropbox进行实际更改的情况下调用的，对吧？

根据您的标题，我假设您期望在初次启动时调用它该应用程序。我认为，这将在您首次在设备上关联帐户时发生，前提是该帐户具有对您的应用程序可见的文件。 （例如，也许您正在使用文件类型权限，并且您链接的帐户已经具有该类型的文件。）否则，由于没有从服务器同步的相关更改，我不希望调用观察者。 / p>

I used DropBox sync api to get sync my app data and import images from Dropbox. Now I wrote an observer to FileSystem. It's working fine with my account but is not working with other accounts. It's not giving any errors. addObserver:self forPathAndChildren:[DBPath root] block:^ does not get called.

 if (![DBAccountManager sharedManager].linkedAccount.linked)
        {
            [[DBAccountManager sharedManager] linkFromController:self];
        }
        else
        {
            if(!dbFileSys)
            {
                dbFileSys = [DBFilesystem sharedFilesystem];
            }
            __weak id weakSelf = self;
            [dbFileSys addObserver:self forPathAndChildren:[DBPath root] block:^
             {
                 [weakSelf loadFiles]; //load files
             }];

        }

This observer called in my account. If i use other account not called.

解决方案

The observer looks fine. I assume it's called if you make actual changes to the target Dropbox, right?

Based on your title, I assume you're expecting this to get called when you first start the app. I think that will happen the first time you link an account on a device, assuming that account has files visible to your app. (E.g. maybe you're using File type permissions and the account you link already has files of that type.) Otherwise, I wouldn't expect the observer to be called, since there were no relevant changes sync'd from the server.
