目标C.获取app delegate.m上的lat / lng信息

Question

AppDelegate.h

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
@interface AppDelegate : UIResponder <UIApplicationDelegate,CLLocationManagerDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (nonatomic, strong) CLLocationManager * locationManager;
@property (nonatomic, strong) CLLocation *currentLocation;

@end

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    NSLog(@"11111");
    CLLocationManager *manager = [[CLLocationManager alloc] init];

    manager.delegate = self;
     [manager requestAlwaysAuthorization];
    //Here you set the Distance Filter that you need
    manager.distanceFilter = kCLDistanceFilterNone;
    // Here you set the Accuracy
    manager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
    NSLog(@"startUpdatingLocation");
    CLAuthorizationStatus status = [CLLocationManager authorizationStatus];
    NSLog(@"startUpdatingLocation %@" , status);



    [manager startUpdatingLocation];

     NSLog(@"22222");
    return YES;
}

第一个问题是，在qsecxswpoi调用许可的弹出窗口在0.5秒~3秒之后被解雇。我不知道为什么要解雇。

即使我总是被批准（我不知道英文版本是如何确切的），[manager requestAlwaysAuthorization];状态总是空的

CLAuthorizationStatus status = [CLLocationManager authorizationStatus];

其次

对于这个阶段，

    -(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(CLLocation *)newLocation{
//    currentLocation = newLocation;
    NSLog(@"locationinfor %@!   ,,, %@!!!!", newLocation.coordinate.latitude,newLocation.coordinate.longitude);


}

它应该去[manager startUpdatingLocation];功能，应该记录didUpdateLocations但它不来NSLog(@"locationinfor %@! ,,, %@!!!!", newLocation.coordinate.latitude,newLocation.coordinate.longitude);。

Answer 1

问题可能是你宣布didUpdateLocations。当你已经定义了一个类成员CLLocationManager *manager时，为什么不使用它。

CLLocationManager *locationManager

编辑：确保您的Info.plist具有用户敏感数据的描述性文本。如果授权未确定，您还可以检查

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    NSLog(@"11111");
    self.locationManager = [[CLLocationManager alloc] init];

    self.locationManager.delegate = self;
     [self.locationManager requestAlwaysAuthorization];
    //Here you set the Distance Filter that you need
    self.locationManager.distanceFilter = kCLDistanceFilterNone;
    // Here you set the Accuracy
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
    NSLog(@"startUpdatingLocation");
    CLAuthorizationStatus status = [CLLocationManager authorizationStatus];
    NSLog(@"startUpdatingLocation %@" , status);



    [self.locationManager startUpdatingLocation];

     NSLog(@"22222");
    return YES;
}

并再次请求。

authorization status
