準則2.16下的iPhone應用拒絕

Question

這是我的應用第二次因GPS背景密鑰而被拒絕。這裏是我使用的代碼：

-(void)stopGPS{ 
[self.locationManagerAll stopUpdatingLocation]; 
self.locationManagerAll.delegate = nil; 
locationManagerAll = nil; 
self.cloop = 1; 

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
[prefs setValue:[NSNumber numberWithBool:NO] forKey:@"UpdateLocation"]; 
[prefs setValue:[NSNumber numberWithInt:0] forKey:@"updationTime"]; 
[prefs synchronize]; 
[set.gpsOnOff setOn:NO]; 
[set.settingsTable reloadData]; 
[self stopThread]; 
} 
-(void)startGPS{ 

if ([CLLocationManager locationServicesEnabled]){ 
    if(self.locationManagerAll == nil){ 
     self.locationManagerAll = [[CLLocationManager alloc] init]; 
     self.locationManagerAll.delegate = self; 
    } 
    self.locationManagerAll.desiredAccuracy = kCLLocationAccuracyHundredMeters; 
    self.locationManagerAll.distanceFilter = kCLDistanceFilterNone; 
    [self.locationManagerAll startUpdatingLocation]; 

}else { 
    [set.gpsOnOff setOn:NO]; 
    [set.settingsTable reloadData]; 
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Location Service Disabled" 
                message:@"To re-enable, please go to Settings and turn on Location Service for this app." 
                delegate:nil 
              cancelButtonTitle:@"OK" 
              otherButtonTitles:nil]; 
    [alert show]; 
    [alert release]; 
} 
} 

這些用於啓動或停止GPS位置上述功能，下面是GPS位置的實現：

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { 
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
if ([oldLocation.timestamp timeIntervalSinceNow] < - 5) return; 
if (newLocation.horizontalAccuracy > 5.0) return; 
if (newLocation.coordinate.latitude == oldLocation.coordinate.latitude && newLocation.coordinate.longitude == oldLocation.coordinate.longitude) return; 
NSString *currentLatitude = [[NSString alloc] 
          initWithFormat:@"%f", 
          newLocation.coordinate.latitude]; 
NSString *currentLongitude = [[NSString alloc] 
           initWithFormat:@"%f", 
           newLocation.coordinate.longitude]; 
[prefs setValue:currentLatitude forKey:@"UpdateLocationLati"]; 
[prefs setValue:currentLongitude forKey:@"UpdateLocationLongi"]; 
[prefs synchronize]; 
[currentLatitude release]; 
[currentLongitude release]; 
if (self.cloop == 1) { 
    /*UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Current location saved." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [alert show]; 
    [alert release]; */ 

    self.cloop = 0; 
    [prefs setValue:[NSNumber numberWithInt:60] forKey:@"updationTime"]; 
    [prefs setValue:[NSNumber numberWithBool:YES] forKey:@"UpdateLocation"]; 
    [prefs synchronize]; 
    [set.gpsOnOff setOn:YES]; 
    [set.settingsTable reloadData]; 
    [self startThread]; 
} 
} 
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{ 
if ([error code] != kCLErrorLocationUnknown) { 
    [self stopGPS]; 
    UIAlertView *alert = [[UIAlertView alloc] init]; 
    [alert setTitle:@"Location"]; 
    [alert setMessage:@"Unable to get current location"]; 
    [alert setDelegate:self.set]; 
    [alert addButtonWithTitle:@"Cancel"]; 
    [alert addButtonWithTitle:@"Retry"]; 
    [alert show]; 
    [alert release]; 

} 
} 

我也使用定時器的螺紋它在每秒鐘之後更新服務器上的位置。當應用程序去背景計時器停止我使用這個代碼來處理這個問題：

- (void)applicationDidEnterBackground:(UIApplication *)application{ 
/* 
Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.*/ 
if ([[UIDevice currentDevice] respondsToSelector:@selector(isMultitaskingSupported)]) { //Check if our iOS version supports multitasking I.E iOS 4 
    if ([[UIDevice currentDevice] isMultitaskingSupported]) { //Check if device supports mulitasking 
     UIApplication *application = [UIApplication sharedApplication]; //Get the shared application instance 


     __block UIBackgroundTaskIdentifier background_task; //Create a task object 
     background_task = [application beginBackgroundTaskWithExpirationHandler: ^{ 
      [application endBackgroundTask:background_task]; 
      //Tell the system that we are done with the tasks 
      background_task = UIBackgroundTaskInvalid; //Set the task to be invalid 
      //System will be shutting down the app at any point in time now 
     }]; 
     //Background tasks require you to use asyncrous tasks 
     dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ 
      //Perform your tasks that your application requires     
      //I do what i need to do here.... synchronously...     
      NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
      if ([[prefs objectForKey:@"updationTime"] intValue] > 0 && [[prefs objectForKey:@"UpdateLocation"] boolValue]) { 
       self.backgroundTimer = [NSTimer timerWithTimeInterval:[[prefs objectForKey:@"updationTime"] intValue] target:self selector:@selector(backgroundTriggerTimer) userInfo:nil repeats:YES]; 
       NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; 
       [runLoop addTimer:backgroundTimer forMode:NSRunLoopCommonModes]; 
       [runLoop run]; 
      } 
      [application endBackgroundTask:background_task]; 
      //End the task so the system knows that you are done with what you need to perform 
      background_task = UIBackgroundTaskInvalid; //Invalidate the background_task 
     }); 
    }else if (![[UIDevice currentDevice] isMultitaskingSupported]) { 
     NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
     if ([[prefs objectForKey:@"UpdateLocation"] boolValue]){ 
      [self stopGPS]; 
     } 
    } 
}else if (![[UIDevice currentDevice] isMultitaskingSupported]) { 
    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
    if ([[prefs objectForKey:@"UpdateLocation"] boolValue]){ 
     [self stopGPS]; 
    } 
} 
} 

這裏是我使用的線程代碼：

-(void)startThread 
{ 
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
if ([[prefs objectForKey:@"UpdateLocation"] boolValue]) { 
    self.updateLocation = [[NSThread alloc] initWithTarget:self selector:@selector(setUpTimerThread) object:nil]; 
    [self.updateLocation start]; 
} 
} 
-(void)stopThread{ 
[self.updateLocation cancel]; 
updateLocation = nil; 
[self.gpsTimer invalidate]; 
} 
-(void)setUpTimerThread 
{ 
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 

if ([[prefs objectForKey:@"updationTime"] intValue] > 0) { 
    self.gpsTimer = [NSTimer timerWithTimeInterval:[[prefs objectForKey:@"updationTime"] intValue] target:self selector:@selector(triggerTimer) userInfo:nil repeats:YES]; 
    NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; 
    [runLoop addTimer:gpsTimer forMode:NSRunLoopCommonModes]; 
    [runLoop run]; 
} 
[pool release]; 
} 
-(void)triggerTimer 
{ 
NSLog(@"***Timer Called after seconds**"); 
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
NSString *location = [[[NSString alloc] initWithFormat:@"%f_%f",[[prefs objectForKey:@"UpdateLocationLati"] doubleValue], [[prefs objectForKey:@"UpdateLocationLongi"] doubleValue]] autorelease]; 
NSString *urlGen = [[[NSString alloc] initWithFormat:@"%@%d/%@",[prefs objectForKey:@"update_user_location"],[[prefs objectForKey:@"USERID"] intValue], location] autorelease]; 
NSLog(@"urlGen: %@", urlGen); 
NSString *rt = [JSONModel stringWithUrl:urlGen]; 
if (self.alertLoop == 1) { 
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"GPS location has been sent. This alert message will only prompt you once." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [alert show]; 
    [alert release]; 
    self.alertLoop = 0; 
} 
NSLog(@"UPDATE LOCATION : %d", [rt intValue]); 
} 

我完全糊塗了。我不知道我是否錯過了一些東西。任何人都可以幫我解決問題。

它看起來並不像你遺漏的東西，但2.16拒絕的可能原因之一是你的應用程序描述中沒有GPS電池警告iTunesConnect中的應用程序元 - 「持續使用GPS可能會減少電池壽命「 或類似的東西。
