我正在使用 GKPeerPickerController，这是我的简单代码：

- (IBAction)turnOn:(id)sender {
    GKPeerPickerController *peerpicker = [[GKPeerPickerController alloc]init];
    peerpicker.delegate = self;
    peerpicker.connectionTypesMask = GKPeerPickerConnectionTypeNearby;
    [peerpicker show];
}

-(GKSession*)peerPickerController:(GKPeerPickerController *)picker sessionForConnectionType:(GKPeerPickerConnectionType)type
{
    [picker dismiss];
    NSLog(@"picker Dismissed");
    return nil;
}

turnOn 是从按钮触发的 IBAction。问题是在选择器被关闭后，应用程序崩溃并出现 EXC_BAD_ACCESS 错误，为什么？我该如何解决？这是来自控制台：

2013-06-01 14:29:00.883 iShare[829:907] picker Dismissed

我的 iPhone 3GS 越狱了，会不会有问题？谢谢！！

您正在从 sessionForConnection 中解散您的选择器，这是一个不寻常的选择，但是调用 [self dismissModalViewControllerAnimated: YES]; 而不是 [picker dismiss] 应该更适合你。
