我真的很犹豫是否要发布关于这个主题的第四个问题，但是根据之前的答案对所有内容进行了三次检查，仍然得到不好的结果。
问题：CLLocationManager 在 iOS6 中没有调用didEnterRegion。
设置：iOS6。
这是与 CLLocationManager 相关的所有功能的代码
myMapViewController.h
@interface FirstViewController : UIViewController <UIApplicationDelegate,CLLocationManagerDelegate, MKMapViewDelegate, UISearchBarDelegate,RKObjectLoaderDelegate >
{
/* variables */
}
@property (strong, nonatomic) CLLocationManager *locationManager;
myMapViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
/* other initialization code */
locationManager = [[CLLocationManager alloc] init];
[locationManager setDelegate:self];
[locationManager setDistanceFilter: kCLLocationAccuracyBest];
[locationManager setDesiredAccuracy: kCLLocationAccuracyBest];
}
- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects {
/* other application code */
Step* step = [_steps lastObject];
CLRegion *tmpReg = [[CLRegion alloc] initCircularRegionWithCenter:step.start_location.coordinate radius:1000 identifier: [step.start_locationLat stringValue] ];
[locationManager startMonitoringForRegion:tmpReg];
NSLog(@"Setting region with latitude %f", tmpReg.center.latitude);
}
- (void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region{
NSLog(@"Monitoring region with latitude %f", region.center.latitude);
}
- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region{
NSLog(@"ENTERED REGION!");
}
}
- (void) locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region{
NSLog(@"EXITED REGION!");
}
- (void)locationManager:(CLLocationManager *)manager monitoringDidFailForRegion:(CLRegion *)region withError:(NSError *)error
{
NSLog(@"Region monitoring failed with error: %@", [error localizedDescription]);
}
应用程序以零警告运行，这是日志：
