iOS 8 定位失败问题

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
