objective-c – EXC_BAD_ACCESS(SIGSEGV) – KERN_INVALID_ADDRE

我们发现您的应用程序在运行iOS 7的iPad上崩溃,这不符合App Store审核指南.

好吧,我上传的时间,iOS7没有启动.

崩溃报告说

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)

在崩溃中我们看到MapKit 0x30ca46a6 – [MKMapView mapViewDidFinishLoadingTiles：].

MapKit是否存在问题？

对于mapkit,下面就是我的内容

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.title = @"Location";
    // Do any additional setup after loading the view.
    CLLocationCoordinate2D cords = {29.32511601390379,48.08847418705136};
    MKCoordinateSpan span = {0.008400,0.008400};
    region = (MKCoordinateRegion) {cords,span};
    mapView.showsUserLocation = YES;
    [mapView setRegion:region animated:YES];
    [mapView setDelegate:self];

    DisplayMap *ann = [[DisplayMap alloc] init];
    ann.coordinate = region.center;
    [mapView addAnnotation:ann];
}

另外我在mapkitviewcontroller中没有dealloc.那很好吗？我问这个错误与内存管理有关.

我的应用程序有5个选项卡.前4个选项卡只是UIWebView.对于webview,我发现我没有把webview放在dealloc中.以下是我在webview中的内容,

- (void)dealloc {
    [super dealloc];
}

现在我的xcode上也没有iOS 7.我需要下载它,但想在此之前询问.

注意：一切都与iOS 6完美配合.

有没有猜到我收到这个错误的原因？
