Nextpeer SDK Version is 2.2.2.
Cocos2dx SDK Version is 3.7.1.
Xcode Version is 6.3.2.
How i can resolve this issue.
I have try following code
#try {
if([Nextpeer isNextpeerSupported])
{
NSLog(#"AAAAAAAAA");
[Nextpeer initializeWithProductKey:#"88b83720cf1fa8e9f2007f29e91b9dd6" andDelegates:[NPDelegatesContainer containerWithNextpeerDelegate:self]];
}
else
NSLog(#"BBBBBBBB");
}
#catch (NSException * e) {
NSLog(#"Exception: %#", e);
}
#finally {
}
but getting exception
