如何使我的ios应用程序显示在“设置”中的“位置服务”中

Question

我写了一个CLLocationManager ios应用程序。但是，我无法看到我的应用程序出现在位置服务中的设置在我的iPhone上。我需要在Xcode中的ios项目中设置plist中的特定值吗？提前感谢！

Answer 1

在iOS-8中，需要进行一些更改：

locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    if([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]){
        [locationManager requestWhenInUseAuthorization];
    }else{
        [locationManager startUpdatingLocation];
    }

需要在plist中添加2个空值的额外键1）NSLocationWhenInUseUsagedescription ption 2）NSLocationAlwaysUsagedescription ption

#pragma mark - CLLocationManagerDelegate

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    NSLog(@"didFailWithError: %@", error);
    UIAlertView *errorAlert = [[UIAlertView alloc]
                               initWithTitle:@"Error" message:@"Failed to Get Your Location" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [errorAlert show];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    NSLog(@"didUpdateToLocation: %@", newLocation);
    CLLocation *currentLocation = newLocation;

    if (currentLocation != nil) {
        NSString *strLat = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude];
        NSString *strLong = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];
    }
}

一旦调用实际需要位置跟踪的代码，它应该会自动出现（每当弹出窗口首次显示：你允许吗...）

试着打这样的电话：

[self.locationManager startUpdatingLocation];

这应该可以做到
