How to check if a file exists in a Dropbox account of a specific user using the Dropbox iOS SDK 1.1?

I am currently developing an application using the Dropbox iOS SDK version 1.1. I am developing an application for iOS version 5.0 and higher. I looked at all the methods in the DBRestClient.h file, which is included in the SDK. I could not find a method that allowed me to check whether a given file exists in a given location in the directory. I was thinking if I can use the following method in the DBRestClient.h file to do the same

- (void)loadMetadata:(NSString*)path;

Here, I thought about using the Location / FileName parameter in the Path parameter to find out if this file exists or not.

I am not entirely sure of the right approach to doing the same. Please suggest some best methods if this is not the case.

The Dropbox SDK does not support search (it only supports a subset of the Dropbox API). To do what you need, you can directly call the REST API lookup method

If you want to stick with the SDK, you can call loadMetadata recursively for each folder level until you find the file you want. But I do not recommend this (imagine if your user is on a cellular network when you make dozens or hundreds of calls).
