libPusher not receiving pushes (obj c) - objective-c

Question

I am trying to implement a OS X (10.10) client for the real time bitcoin exchange rate from bitstamp.com. They offer a great api, unfortunately I can't get the websocket api (https://www.bitstamp.net/websocket/) to work in an OS X Objective C app.
Everyone is pointing me to the libPusher Github project (https://github.com/lukeredpath/libPusher) but I tried literally everything I can think of, I can't get it to receive any pushes on 10.10.
Following the wiki page I downloaded the pre-compiled static library and dragged all files into my projects (I also made sure the "copy" checkbox was checked) and my sample applications compiles. Unfortunately, I never see either the "event through block" or "event through delegate" on the console. However I know that trades happened in the mean time, so that can't be the issue. Any ideas?
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
// Insert code here to initialize your application
PTPusher* client = [PTPusher pusherWithKey:#"de504dc5763aeef9ff52" delegate:self encrypted:YES];
[client connect];
PTPusherChannel *channel = [client subscribeToChannelNamed:#"live_trades"];
[channel bindToEventNamed:#"trade" handleWithBlock:^(PTPusherEvent *channelEvent) {
// channelEvent.data is a NSDictionary of the JSON object received
NSLog(#"event through block"); // <-- never called
}];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(didReceiveEventNotification:)
name:PTPusherEventReceivedNotification
object:client];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(didReceiveChannelEventNotification:)
name:PTPusherEventReceivedNotification
object:channel];
}
- (void)didReceiveEventNotification:(NSNotification *)notification // <-- never called
{
NSLog(#"event through delegate");
PTPusherEvent *event = [notification.userInfo objectForKey:PTPusherEventUserInfoKey];
}

After talking to the developer I found the problem:
In my code, the PTPusher instance is a local variable defined in the .m file.
However, it needs to be a strong variable defined in the .h file:
#property (strong) PTPusher* client;
Then in the .m file, you can easily use it (don't forget to synthesize it!):
self.client = [PTPusher pusherWithKey:#"de504dc5763aeef9ff52" delegate:self encrypted:YES];
[self.client connect];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(didReceiveEventNotification:)
name:PTPusherEventReceivedNotification
object:self.client];
PTPusherChannel *channel = [client subscribeToChannelNamed:#"live_trades"];
