But while creating instance of UAirship, it is showing error that UAirship is undeclared.i have implemented urbanairship upto http://urbanairship.com/docs/apns_test_client.html#prerequisite and after then i do not know what should i do ? Waiting for response. Thanks.
回答1:
Have you included UAirship.h and UAPush.h ?
回答2:
I got something similar just now. Might not be the same problem, but there seems to be a massive bug in the UA library - a combination of careless code design, and badly written code.
Apparently ... you MUST NOT make calls to "UAPush" until AFTER you have invoked
[UAirship takeOff:...]
This shouldn't be a problem. Firstly, UA shouldn't crash! Secondly, there's plenty of calls to UAPush that make sense before calling takeOff. So far as I can tell, this is undocumented (like most of UA, sadly :( ). i.e. I'd read through the official website and the scant docs multiple times, and never saw mention of this requirement.

See https://docs.urbanairship.com/display/DOCS/Getting+Started%3A+iOS%3A+Push, the mostly simplest guide with pictures... Watch for the possible cases you have missed which you shouldn't have.
