GSDropboxActivity is an iOS 6 UIActivity subclass for uploading to Dropbox.

Usage instructions

1. Install the Dropbox iOS SDK

Download the latest Dropbox iOS SDK and follow Dropbox's instructions for incorporating it into your app.

GSDropboxArchive assumes you have configured the shared DBSession object appropriately. If you follow Dropbox's integration instructions you will have done this. In essence, you just need to make sure you include this in your application delegate's application:didFinishLaunchingWithOptions: method:

#import <DropboxSDK/DropboxSDK.h>

...

DBSession* dbSession = [[DBSession alloc] initWithAppKey:@"APP_KEY"
                                               appSecret:@"APP_SECRET"
                                                    root:ACCESS_TYPE]; // either kDBRootAppFolder or kDBRootDropbox
[DBSession setSharedSession:dbSession];

2. Add GSDropboxActivity to your project

Just copy the GSDropboxActivity folder into your project.

3. Add a GSDropboxActivity object to your list of custom activities and share some NSURL objects

GSDropboxActivity can share NSURL objects where each object is the URL of a file on the local disk.

- (void)handleShareButton:(id)sender
{
    NSArray *itemsToShare = @[
        // Your items to share go here.
        // GSDropboxActivity can share NSURL objects where each object is
        // the file URL to a file on disk.
    ];
    NSArray *applicationActivities = @[
        [[GSDropboxActivity alloc] init]
    ];
    UIActivityViewController *vc = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare
                                                                     applicationActivities:applicationActivities];

    // Present modally - suitable for iPhone.
    // On iPad, you should present in a UIPopoverController
    [self presentViewController:vc animated:YES completion:NULL];
}
