我在 iOS 中使用 Nextpeer 和 cocos2dx。我已经成功配置了带有 cocos2dx 的 Nextpeer sdk。在“AppController.mm”中，我使用以下代码

    [Nextpeer initializeWithProductKey:@"KEY" andDelegates:[NPDelegatesContainer containerWithNextpeerDelegate:self]];

但我的代码因以下日志而崩溃

Nextpeer SDK 版本为 2.2.2。Cocos2dx SDK 版本为 3.7.1。Xcode 版本是 6.3.2。

我该如何解决这个问题。

我尝试了以下代码

@try {
    if([Nextpeer isNextpeerSupported])
    {
        NSLog(@"AAAAAAAAA");
        [Nextpeer initializeWithProductKey:@"88b83720cf1fa8e9f2007f29e91b9dd6" andDelegates:[NPDelegatesContainer containerWithNextpeerDelegate:self]];
    }
    else
        NSLog(@"BBBBBBBB");
}
@catch (NSException * e) {
    NSLog(@"Exception: %@", e);
}
@finally {

}

但得到异常
