位置服务在iPhone 5中处于"未激活"状态

Question

甚至我的应用程序都在后台注册位置更新.

在我的代码中:

self.locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers;
self.locationManager.distanceFilter = 2500;

我没有搬到任何地方.因此,在控制台日志中完成15分钟后,我收到此消息"位置图标现在应处于"非活动状态".从这一点开始,我的应用程序不在后台运行.

它只在iPhone 5中发生.

@更新

这是我的代码

self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
[self.locationManager setPurpose:@"Enable Location service for \"My App\" to track your"];
self.locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers;

/* Notify changes when device has moved x meters.
 * Default value is kCLDistanceFilterNone: all movements are reported.
 */
self.locationManager.distanceFilter = 2500;
[self.locationManager startUpdatingLocation];

Answer 1

当位置服务变为非活动状态时,您的应用是否在后台？

如果您不想在后台暂停位置更新,则需要设置pausesLocationUpdatesAutomatically flag,

if ([self.locationManager respondsToSelector:@selector(pausesLocationUpdatesAutomatically)]) {
    self.locationManager.pausesLocationUpdatesAutomatically = NO;
}
