Apple のコア ロケーション ドキュメントに記載されているように、独自のロケーション取得クラスを設定しました。
MyCLControl.h
:
@protocol MyCLControllerDelegate
@required
- (void)locationUpdate:(CLLocation *)location;
- (void)locationError:(NSError *)error;
@end
@interface MyCLController : NSObject <MyCLControllerDelegate, CLLocationManagerDelegate> {
CLLocationManager *locationManager;
id <MyCLControllerDelegate> delegate;
}
@property (nonatomic, retain) CLLocationManager *locationManager;
@property (strong) id <MyCLControllerDelegate> delegate;
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation;
- (void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error;
- (BOOL) connected;
@end
MyCLController.m
のandinit
メソッドlocationManager:didUpdateToLocation:fromlocation
:
- (id) init {
self = [super init];
if (self != nil) {
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
//locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
}
return self;
}
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
[self.delegate locationUpdate:newLocation];
}
私がそれを呼んでいる方法は次のとおりです。
- (void)viewDidLoad {
MyCLController *locationController = [[MyCLController alloc] init];
locationController.delegate = locationController.self;
[locationController.locationManager startUpdatingLocation];
}
- (void)locationUpdate:(CLLocation *)location {
NSLog(@"%@", location);
}
[MyCLController locationUpdate:]: unrecognized selector sent to instance
ヒットするとランタイムエラーが発生します[self.delegate locationUpdate:newLocation]
。
