Objective c 使用重要位置管理器的应用程序在设备上意外关闭，但在模拟器上未关闭

我希望有人能帮助我。我正在xcode 4.5.2上开发一个iOS 6应用程序，该应用程序使用重大更改位置服务，它检测到本地化使用反向地理编码，并使用web服务将国家代码、adminArea、subAdminArea、locality和sublocality上传到在线数据库。在iphone模拟器上，它工作正常，但在iOS设备上，它会毫无理由地直接关闭。如果我将位置服务停用到我的应用程序，它会正常运行，但当它有权使用这些服务时，它会在一秒钟内关闭

代码如下：

        #import "searchViewController.h"
    #import <CoreLocation/CoreLocation.h>
    #import "resultViewController.h"

    @interface searchViewController () <UIPickerViewDataSource, UIPickerViewDelegate, CLLocationManagerDelegate, NSXMLParserDelegate>
    @property (weak, nonatomic) IBOutlet UITextView *errorSearchTextView;
    - (IBAction)searchButton:(id)sender;
    @property (weak, nonatomic) IBOutlet UIPickerView *bloodTypePicker;

    @end

    @implementation searchViewController

    @synthesize bloodType,locationManager,geocoder, webData, xmlParser, soapResults, localizacion, usuarios, correos, coincidencias;

- (void)viewDidLoad
{
    [super viewDidLoad];
    bloodType = [[NSArray alloc] initWithObjects:@"A+", @"A-", @"B+", @"B-", @"O+", @"O-", @"AB+", @"AB-", nil];
    [self startLocating];//here is where i start the location monitoring
    // Do any additional setup after loading the view.
}

//这些是在接收到位置更新时调用的方法

-(void) locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    CLLocation *location = [locations lastObject];
    [self geocoder:location];
    localizacion = 0;
}

//metodo para el geocoder
-(void) geocoder:(CLLocation *)location
{
    if (!geocoder) geocoder = [[CLGeocoder alloc] init];
    [geocoder reverseGeocodeLocation:location  completionHandler:^(NSArray *placemarks, NSError *error) {
        if ([placemarks count]>0)
        {
            NSString *usuario = [[NSUserDefaults standardUserDefaults] stringForKey:@"usuario"];
            CLPlacemark *place = [placemarks objectAtIndex:0];

            NSMutableURLRequest *theResquest = [NSMutableURLRequest requestWithURL:url];
            NSString *messageLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
            [theResquest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
            [theResquest addValue:@"urn:LoginAction" forHTTPHeaderField:@"SOAPAction"];
            [theResquest addValue:messageLength forHTTPHeaderField:@"Content-Length"];
            [theResquest setHTTPMethod:@"POST"];
            [theResquest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
            webData = [NSMutableData data];
            localizacion = 0;
            NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theResquest delegate:self];
            if (theConnection) {
                self.errorSearchTextView.text = NSLocalizedString(@"BloodyHelp is updating your data.", @"updating location");
            } else {
                self.errorSearchTextView.text = NSLocalizedString(@"Conection error.\n", @"connection error updating");
            }
        }
    }];
}

还有很多，但是太长了。够了吗

编辑我把控制台拿出来：

***由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：'-[\u NSCFString appendString::]：nil参数'

我终于解决了这个问题，崩溃日志和控制台输出是找到错误的确切点并解决它的关键，问题不在location services，问题是在make gocoding之后，sub Adminarea为空，我试图附加到字符串，因为它的值为零，它抛出异常并关闭

解决方案就是创建这个

 NSString *subAdminArea = [NSString StringWithFormat:@"%d",place.subAdministrativeArea];

因此，如果place.subAdministrativeArea的值为零，则为“”字符串

建议：要解决此问题，请将设备连接到xcode，并在看到console out时发生错误，（您可以将“console标志”与NSLog放在一起，以了解错误的位置

谢谢！！

你有崩溃日志吗？还没有。我怎么能得到这些呢？从Xcode菜单栏-窗口->管理器，然后单击“设备”部分，然后单击左侧栏中设备附近的显示箭头，然后单击“设备日志”。请确保您的计算机上有应用程序包和dSYM，并且可通过聚光灯进行索引，以便您可以对其进行象征。您的应用程序是否真的命名为BloodyHelp？是的，它是真实名称
