1、导入CoreLocation.frameWork

2，到Plist文件中增加：

NSLocationWhenInUseDescription//使用app时是否允许app使用定位的提示语
NSLocationAlwaysUsageDescription//不使用app时是否允许app使用定位的提示语

3，在AppDelegate.h中添加

#import <CoreLocation/CoreLocation.h>
@interface AppDelegate : NSObject <CLLocationManagerDelegate> //协议
@property(nonatomic) CLLocationManager *locationManager;
@end 

4，在AppDelegate.m中添加

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // Override point for customization after application launch.

    [UIApplication sharedApplication].idleTimerDisabled = TRUE;

    self.locationManager = [[CLLocationManager alloc] init];

    self.locationManager.delegate = self;

    return YES;

}

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status

{

    switch (status) {

        case kCLAuthorizationStatusNotDetermined:

            if ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {

                [self.locationManager requestWhenInUseAuthorization];     //NSLocationWhenInUseDescription

                [self.locationManager requestAlwaysAuthorization];

                  }

            break;

        default:

            break;

    }

}

实现一进入APP就授权定位
