Google Drive API - list specific files in a specific folder using Objective-C
问题 I'm working on a Google Drive integration for iOS and I've hit a snag—I need to check for the existence of a file in a folder, but I keep getting a "500 Internal Error" response no matter how I seem to put together the request. I think this should be legit: // self.directoryDriveFile.identifier is a valid folder identifier retrieved on previous request GTLQueryDrive *query = [GTLQueryDrive queryForChildrenListWithFolderId:self.directoryDriveFile.identifier]; // add query to specify the file
