應用程序崩潰捏地圖輸入地圖

我正在使用MKMapKit地圖。我添加了註釋，甚至提供了setCenterCoordinate和setRegion。我正在編譯使用iOS7.0，但我的設備有iOS6.1版本。當我捏緊輸入時，放大它會崩潰。我試過運行儀器，但沒有看到任何內存問題。所有分配和泄漏都得到妥善處理。請任何人知道這是什麼問題？應用程序崩潰捏地圖輸入地圖

代碼提供註解：

NSMutableArray *arr = [[NSMutableArray alloc] init]; 
    for(int i =0;i<[mListArr count];i++) 
    { 
     NSDictionary *theDict = [mListArr objectAtIndex:i]; 
     CLLocationCoordinate2D annotationCoord; 

     annotationCoord.latitude = [[theDict objectForKey:kLatitudeKey] doubleValue]; 
     annotationCoord.longitude = [[theDict objectForKey:kLongitudeKey] doubleValue]; 

     MKPointAnnotation *annotation = [[MKPointAnnotation alloc] init]; 
     annotation.coordinate = annotationCoord; 
     annotation.title = [theDict objectForKey:kAddressKey]; 
     annotation.subtitle = [theDict objectForKey:kRegionKey]; 
     [arr addObject:annotation]; 

    } 
    if([arr count]>0) 
    { 
     [mapView addAnnotations:arr]; 

     NSDictionary *theDict = [mListArr objectAtIndex:0]; 
     CLLocationCoordinate2D annotationCoord; 

     annotationCoord.latitude = [[theDict objectForKey:kLatitudeKey] doubleValue]; 
     annotationCoord.longitude = [[theDict objectForKey:kLongitudeKey] doubleValue]; 

     [mapView setCenterCoordinate:annotationCoord animated:YES]; 

     MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(annotationCoord, 50000, 50000); 
     [mapView setRegion:[mapView regionThatFits:region] animated:YES]; 

    }

提前感謝！

編輯：我正在使用ARC。

編輯：以下是日誌：

什麼是錯誤信息？ – Larme

沒有錯誤信息。它顯示了主要的EXC_BAD_ACCESS。 –

使用NSZombies來幫助你知道你想訪問的對象不存在（已經存在）。 – Larme

應設置異常斷點在Xcode和應用程序崩潰時您將可以訪問lldb控制檯以獲取與bt的回溯，這可以非常有幫助。
