Well the time when I uploaded, iOS7 was not launched.

Is MapKit is giving problem?
MapKit 有问题吗？
For mapkit, below is what I have
对于mapkit，下面是我所拥有的
- (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];
}
Also I don't have dealloc in mapkitviewcontroller. Is that fine? I am asking as this error is related to memory management.
另外我在 mapkitviewcontroller 中没有 dealloc。可以吗？我问这个错误与内存管理有关。
My App was having 5 tabs. First 4 tabs are just UIWebView. For webview, I found that I didn't put webview in dealloc. Below is what I had in webview,
我的应用程序有 5 个标签。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];
}
Right now I don't have iOS 7 on my xcode too. I need to download that, but thought to ask before here.
现在我的 xcode 上也没有 iOS 7。我需要下载那个，但想在这里之前问一下。
Note:All is working perfectly with iOS 6.
注意：一切都与 iOS 6 完美配合。
Any guesses why I am getting this error?
猜猜我为什么会收到这个错误？

When I put mapViewin dealloc, the problem get solved.
当我放入mapViewdealloc时，问题就解决了。
On further investigation, also noticed that I didn't added title for DisplayMap.
在进一步调查中，还注意到我没有为DisplayMap.
DisplayMap *ann = [[DisplayMap alloc] init];
ann.title = @"My Location";

Did set the map view delegate to nil before navigating away from the page. Also I think there is some memory management issue with IOS maps. So It is better to release maps in the deallocmethod.
在离开页面之前，将地图视图委托设置为 nil。另外我认为 IOS 映射存在一些内存管理问题。所以最好在dealloc方法中释放maps 。
