| Re: [paho-dev] MQTT Objective-C Client |
Hi Jeff,
I don't know anything about the objc client, but you're in good
company - other people have wrapped libmosquitto on iphone in the past
- like https://github.com/njh/marquette for example. Facebook use it
in their mobile apps as well, but I don't know more than that.
Cheers,
Roger
