Getting Started Using the DropboxSDK for iOS: Requirements: 1. You need the 4.2 version of the iPhone SDK. The version of your Xcode should be at least 3.2.5. 2. You need to have registered as a Dropbox application with mobile access at http://www.dropbox.com/developers/apps. You should have an app key and secret. Building and using the example app: 1. Open the project file in examples/DBRoulette/DBRoulette.xcodeproj 2. Fill in the values for appKey, appSecret, and root in DBRouletteAppDelegate.m application:didFinishLaunchingWithOptions: 3. Make sure the build is set to Simulator. This setting should be near the top-left corner of Xcode. 4. Build and Run app 5. Once running, make sure you can use the app to login and view photos in your Photos Dropbox folder without getting errors. If you cannot run the app without getting errors, make sure your consumer key and consumer token are correct. Also make sure that your app has been approved by Dropbox for mobile access. Adding DropboxSDK to your project: 1. Open your project in Xcode 2. Right-click on your project in the files tab of the left pane and select "Add Files to '<PROJECT_NAME>'" 4. Navigate to where you uncompressed the Dropbox SDK and select the DropboxSDK.framework subfolder 5. Select "Copy items into destination group's folder" 6. Press Add button 7. Ensure that you have the Security.framework and QuartzCore.framework are added to your project. To do this in Xcode4, select your project file in the file explorer, select your target, and select the "Build Phases" sub-tab. Under "Link Binary with Libraries", press the + button, select Security.framework, and press Add. Repeat for QuartzCore.framework if necessary. 8. Build your application. At this point you should have no build failures or warnings Using the Dropbox SDK: To learn more about using the Dropbox SDK, there is a tutorial on the Developers page at https://www.dropbox.com/developers_beta/start/authentication#ios.
