I'm using the API below to insert a file in iMessage context, and i'm using the alternate file name to customize my sent attachment's name. However, it seemingly doesn't work.
- (void)insertAttachment:(NSURL *)URL withAlternateFilename:(NSString *)filename completionHandler:(void (^)(NSError *))completionHandler;
Maybe it's a bug? Or just because the API is not finished?
Hoping to get some answer, thanks in advance!
