crash - 在iOS7中[提示显示]导致应用崩溃

Question

我在iOS6，iOS5中的代码工作正常，但是在我安装xcode5并在iOS7中运行我的应用程序之后。该应用程序在[alert show]行中崩溃了。错误信息是:线程1:EXC_BAD_ACCESS(代码= 1，地址= 0x3)

我不知道为什么任何人都可以帮助我。谢谢!

我的代码:

- (void) whetherRememberDialog{

dialogFlag = WHETHER_REMEMBER_DIALOG;

    NSString *titleInfo = @"Whether remember?";
    NSString *cancelInfo = @"cancel";
    NSString *okInfo = @"Ok";

    UIAlertView *storeQuesitonDialog = [[UIAlertView alloc] initWithTitle:titleInfo
                                                                  message:nil
                                                                 delegate:self
                                                        cancelButtonTitle:cancelInfo
                                                        otherButtonTitles:okInfo, nil];
    //[storeQuesitonDialog show];
    [storeQuesitonDialog performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:YES]; // In this line the app is crash this codes 
    [storeQuesitonDialog release];

}

由于ARC，您无法在iOS 7中手动释放对象。 ARC为您管理对象的重新分配，因此您不应释放对象。这可能会导致ARC在完成操作后释放对象，从而引发错误。另外，如果您释放警报 View ，它应该如何显示在屏幕上？删除发行版可能会为您解决此问题。
