Question

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，在选择器被解雇后，应用程序崩溃并出现EXC_BAD_ACCESS错误，为什么？我怎么解决？这是来自控制台：

2013-06-01 14:28:57.659 iShare[829:907] BTM: attaching to BTServer
2013-06-01 14:29:00.873 iShare[829:907] BTM: local device power state changed
2013-06-01 14:29:00.876 iShare[829:907] BTM: power is now on
2013-06-01 14:29:00.883 iShare[829:907] picker Dismissed

我的iPhone 3GS越狱了，这可能是个问题吗？谢谢！

Answer 1

你正在从sessionForConnection中解雇你的选择器，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。
