objective-c使用Cordova dropbox pugin如何通过从文件列表中选择特定文件从Dropbox服务器下载文件

我需要知道如何从文件列表中下载文件，而不在代码中提供特定的文件名。



NSArray * paths = NSSearchPathForDirectoriesInDomains （NSDocumentDirectory，NSUserDomainMask，YES）;

NSString * documentsDirectory = [paths objectAtIndex：0]; //获取文档目录



NSString * localPath = [documentsDirectory stringByAppendingPathComponent：@somefile.txt];



NSString * dropBoxFile = @/ somefile.txt;



这是我为单个文件创建的，我知道这个名字。任何人都知道从文件列表中选择文件的解决方案请帮帮我。

I need to know how can i download a file from a list of files,without giving the specific file name in the code.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex: 0]; // Get documents directory

NSString *localPath = [documentsDirectory stringByAppendingPathComponent:@"somefile.txt"];

NSString *dropBoxFile = @"/somefile.txt";

This is how i created for a single file of which i know the name.Anyone who know the solution to select a file from a list of files please help me.
