app using significant location manger closes unexpectedly on devices but not on simulator
I hope some one can help me. I'm developing a iOS 6 app on xcode 4.5.2, the app use significant-change location service, it detects the localization uses reverse geocoding and upload the country code, adminArea, subAdminArea, locality and sublocality to an online DB using a web service. on the iphone simulator it works fine, but on iOS devices it directly get closed with no reason. if i deactivate the location services to my app it runs ok, but when it have permission to use these it closes within one second.
this is the code:
#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.
}
//this is the metod that starts the location manager.
- (void) startLocating
{
if ([CLLocationManager locationServicesEnabled])//si los servicios de localizacion estan activados.
{
if (nil == locationManager) {
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
[locationManager startMonitoringSignificantLocationChanges];
}
} else
{
self.errorSearchTextView.text = NSLocalizedString(@"location services are not available, app will not work properly, please activate these and restart the app.", @"localization not available");
}
}
//these are the methods called when a location update is received.
-(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"];

NSMutableURLRequest *theResquest = [NSMutableURLRequest requestWithURL:url];

[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");
}
}
}];
}
I really don't know what to do. cause in the simulator everything works fine. P.D. I'm new progamming at objetive-c

1 Answer
I finally solve this, the crash logs and the console out was the point to find the exact point of the error and solve it, the problem was not at the location services, the problem was than after make gocoding the sub Adminarea was null and i was trying to append to a string, since it's value was nil it trows an exception and close.
the solution was to create this
NSString *subAdminArea = [NSString StringWithFormat:@"%d",place.subAdministrativeArea];
so if the value of place.subAdministrativeArea is nil it is an "" Strging.
advice: to solve the problem connect the device to xcode and make the error happen while you see console out, (you can put " console flags" with NSLog to know where is the error.
Thanks!!
