位置服务在iOS 6不工作 [英] Location Services in iOS 6 not working

问题描述

   - （void）locationManager：（CLLocationManager *）manager 
 didUpdateToLocation：（CLLocation *）newLocation 
 fromLocation：（CLLocation *）oldLocation {
 static int i = 0; 
 if（[self getCurrentLocation] == nil）{
 i ++; 
 if（i> 3）{
 [[self locationManager] stopUpdatingLocation]; 
 useMyLocation = NO; 
 [self locationUpdated]; 
} 
} else {
 [self locationUpdated]; 
} 
} 
 
  - （void）alertView：（UIAlertView *）anAlertView clickedButtonAtIndex：（NSInteger）buttonIndex {
 if（buttonIndex == 1）{
 self.useMyLocation = YES; 
 [[self locationManager] startUpdatingLocation]; 
} else {// buttonIndex == 0 
 self.useMyLocation = NO; 
 [self locationUpdated]; 
} 
  

}

这是一个在ios 4和5的工作代码。我的问题是，我无法获得位置在ios 6工作。该应用程序甚至不要求用户的权限。阅读完这些是我到目前为止所尝试的：

• CFBundleDisplayName解决方案。我已经有CFBundleDisplayName在我的plist。




• 将位置管理器的属性pausesLocationUpdatesAutomatically设置为NO，如下所示：

...

   - （CLLocationManager * ）locationManager {
 if（locationManager！= nil）{
 return locationManager; 
} 
 CLLocationManager * tmp = [[CLLocationManager alloc] init]; 
 tmp.pausesLocationUpdatesAutomatically = NO; //！@＃
 [self setLocationManager：tmp]; 
 [tmp release]; 
 [locationManager setDesiredAccuracy：kCLLocationAccuracyBest]; 
 [locationManager setDelegate：self]; 
 return locationManager; 
} 
  

我还阅读了 locationManager：didUpdateLocations： code>，我不知道如何在代码中实现它，也不知道如果这是解决方案。

解决方案<

  [locationManager startUpdatingLocation]; 
  

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation{
    static int i=0;
    if([self getCurrentLocation]==nil){
        i++;
        if(i>3){
            [[self locationManager] stopUpdatingLocation];
            useMyLocation = NO;
            [self locationUpdated];
        }
    }else{
        [self locationUpdated];
    }
}

- (void)alertView:(UIAlertView *)anAlertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if(buttonIndex==1){
    self.useMyLocation = YES;
    [[self locationManager] startUpdatingLocation];
}else{ // buttonIndex==0
    self.useMyLocation = NO;
    [self locationUpdated];
}

}

This is a working code in ios 4 and 5. My problem is that I can't get location to work in ios 6. The app doesn't even asks for permission from the user. After reading around this is what I've tried so far:

• CFBundleDisplayName solution. I already had CFBundleDisplayName in my plist. I tried removing it and adding it again - no go.

• setting the property pausesLocationUpdatesAutomatically of Location Manager to NO like this:

...

- (CLLocationManager *)locationManager{
        if (locationManager != nil){
            return locationManager;
        }   
        CLLocationManager *tmp = [[CLLocationManager alloc] init];
        tmp.pausesLocationUpdatesAutomatically = NO;  //!@#
        [self setLocationManager:tmp];
        [tmp release];
        [locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
        [locationManager setDelegate:self];
        return locationManager;
    }

I also read about locationManager:didUpdateLocations: , I didn't know how to implement it in the code, also i'm not sure if that's the solution.

解决方案

Do you ever start the location manager?

[locationManager startUpdatingLocation];
