首先plist定义两个string：
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
然后调用
[self.locationManager requestWhenInUseAuthorization]
或者
[self.locationManager requestAlwaysAuthorization]
例如
#import "ViewController.h"
@import CoreLocation;
@interface ViewController ()
@property (strong, nonatomic) CLLocationManager *locationManager;
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// ** Don't forget to add NSLocationWhenInUseUsageDescription in MyApp-Info.plist and give it a string
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
// Check for iOS 8. Without this guard the code will crash with "unknown selector" on iOS 7.
if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
[self.locationManager requestWhenInUseAuthorization];
}
[self.locationManager startUpdatingLocation];
}
// Location Manager Delegate Methods
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
NSLog(@"%@", [locations lastObject]);
}
@end
