ios6 - 有谁知道如何为 iOS 6 设置 plist 的演练或教程？

Question

我需要设置 plist 以允许 CLLocation 在后台更新当前位置。

Answer 1

以下是设置地理围栏的方法：

{
  self.manager = [[CLLocationManager alloc] init];
  self.manager.delegate = self;

  CLLocationCoordinate2D location;

  location.latitude  = <some lat>;
  location.longitude = <some long>;

  [self.manager startMonitoringForRegion:
   [[CLRegion alloc] initCircularRegionWithCenter: location
                                           radius: 1.0
                                       identifier: @"someplace"]];
}

然后实现委托方法以适当地响应：

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region
{ NSLog (@"didEnterRegion"); }

- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region
{ NSLog (@"didExitRegion"); }

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{ NSLog (@"monitoringDidFailForRegion"); }

- (void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region
{ NSLog (@"didStartMonitoringForRegion"); }
