There is an issue with the current version of FHSTwitterEngine and posting images. I had the same issue in my app, but was able to solve it using the updates from this forked version:
https://github.com/alvani/FHSTwitterEngine/blob/master/FHSTwitterEngine/FHSTwitterEngine.m
It's easiest to just copy/paste that into FHSTwitterEngine.m, but here's the specific changes you'll need:
On or around Line 1599:
- (NSError *)sendPOSTRequestForURL:(NSURL *)url andParams:(NSDictionary *)params
...
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"\r\n",key] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:data];
Add the following code below:
if ([obj isKindOfClass:[NSData class]]) {
[body appendData:[#"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
}
On or around Line 688:
- (NSError *)postTweet:(NSString *)tweetString withImageData:(NSData *)theData inReplyTo:(NSString *)irt {
...
NSMutableDictionary *params = [NSMutableDictionary dictionary];
params[#"media[]"] = theData;
Add the following code below:
params[#"status"] = tweetString;
Hope this helps!
