Periscope iOS ReplayKit

Classes for parsing Periscope's iOS ReplayKit Streaming metadata (chats, hearts, joins, etc). Data is passed from Periscope's ReplayKit extension to your app via the serviceInfo dictionary in the broadcastController:didUpdateServiceInfo: method.

Usage

Include the contents of the PTVReplayKitServiceInfo directory in your project. Then implement the broadcastController:didUpdateServiceInfo: method (from the RPBroadcastControllerDelegate protocol) similar to the following:

- (void)broadcastController:(RPBroadcastController *)broadcastController didUpdateServiceInfo:(NSDictionary <NSString *, NSObject <NSCoding> *> *)serviceInfo {
   NSString *format = (NSString *)serviceInfo[@"format"];
   if (format && [format isEqualToString:@"periscope/v1"]) {
       dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
           PTVReplayKitServiceInfo *periscopeServiceInfo = [[PTVReplayKitServiceInfo alloc] initWithDictionary:serviceInfo];
           for (__kindof PTVReplayKitServiceInfoMessage *message in periscopeServiceInfo.messages) {
               if ([message isKindOfClass:PTVReplayKitServiceInfoMessageChat.class]) {
                   PTVReplayKitServiceInfoMessageChat *chat = message;
                   NSLog(@"Got chat message %@ from %@ with color %@", chat.text, chat.user.username, chat.color);
               } else if ([message isKindOfClass:PTVReplayKitServiceInfoMessageHeart.class]) {
                   PTVReplayKitServiceInfoMessageHeart *heart = message;
                   NSLog(@"Got heart from %@ with color %@", heart.user.username, heart.color);
               } else if ([message isKindOfClass:PTVReplayKitServiceInfoMessageJoin.class]) {
                   PTVReplayKitServiceInfoMessageJoin *join = message;
                   NSLog(@"%@ joined with color %@", join.user.username, join.color);
               } else if ([message isKindOfClass:PTVReplayKitServiceInfoMessageScreenshot.class]) {
                   PTVReplayKitServiceInfoMessageScreenshot *screenshot = message;
                   NSLog(@"%@ took screenshot with color %@", screenshot.user.username, screenshot.color);
               } else if ([message isKindOfClass:PTVReplayKitServiceInfoMessageShare.class]) {
                   PTVReplayKitServiceInfoMessageShare *share = message;
                   NSLog(@"%@ shared on %@ with color %@", share.user.username, share.service, share.color);
               } else if ([message isKindOfClass:PTVReplayKitServiceInfoMessageViewerCount.class]) {
                   PTVReplayKitServiceInfoMessageViewerCount *count = message;
                   NSLog(@"Viewer count changed to %ld", (long int)count.viewerCount);
               }
           }
       });
   }
