iOS9.1 判断定位是否可用 并定位自己位置

由于iOS9.1关闭整个系统定位会在调用定位时直接出提示，所以没有做判断 ，这个只是在判断应用定位是否可用，以及定位不到的情况！！

你需要在info.plist表里面添加两条变量

在Info.plist中加入两个缺省没有的字段

• NSLocationAlwaysUsageDescription

• NSLocationWhenInUseUsageDescription

这两个字段没什么特别的意思，就是自定义提示用户授权使用地理定位功能时的提示语。

#import <CoreLocation/CoreLocation.h>
@interface ViewController : UIViewController<CLLocationManagerDelegate>

{
    CLLocationDegrees lati;
    CLLocationDegrees longti;
    
}

/**
 *  地图
 */
@property (nonatomic, strong)CLLocationManager *cllocationManager;

// 设置地图启用定位

- (void)setMap {

        //定位功能可用，开始定位
        _cllocationManager = [[CLLocationManager alloc]init];
        _cllocationManager.delegate = self;
        _cllocationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;
        [_cllocationManager requestWhenInUseAuthorization];
        [_cllocationManager startUpdatingLocation];
        

}

// 判断定位是否可用

- (void)locationManager: (CLLocationManager *)manager didFailWithError: (NSError *)error {

    
    NSString *errorString;
    [manager stopUpdatingLocation];
    NSLog(@"Error: %@",[error localizedDescription]);
    switch([error code]) {
        case kCLErrorDenied:
            //Access denied by user
            errorString = @"用户关闭";
            // 定位不可用 —— 传虚拟经纬度
            lati = 0.000000;
            longti = 0.000000;
            //Do something...
            break;
        case kCLErrorLocationUnknown:
            //Probably temporary...
            errorString = @"位置数据不可用";
            //Do something else...
            break;
        default:
            errorString = @"未知错误";
            break;
    }
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Error" message:errorString delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
    [alert show];

}

// 代理方法 地理位置反编码

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations {
    NSLog(@"5");
    CLLocation *newlocation = locations[0];
    CLLocationCoordinate2D oCoordinate = newlocation.coordinate;
    NSLog(@"经度：%f，维度：%f",oCoordinate.longitude,oCoordinate.latitude);
    // 给经纬度全局属性赋值
    lati = oCoordinate.latitude;
    longti = oCoordinate.longitude;
    
//    [NSTimer scheduledTimerWithTimeInterval:8.0 target:self selector:@selector(action:) userInfo:nil repeats:nil];
    [_cllocationManager stopUpdatingLocation];
    
        CLGeocoder *geocoder = [[CLGeocoder alloc]init];
        [geocoder reverseGeocodeLocation:newlocation completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
            for (CLPlacemark *place in placemarks) {
                NSDictionary *location =[place addressDictionary];
                NSLog(@"国家：%@",[location objectForKey:@"Country"]);
                NSLog(@"城市：%@",[location objectForKey:@"State"]);
                NSLog(@"区：%@",[location objectForKey:@"SubLocality"]);
                NSLog(@"位置：%@", place.name);
                NSLog(@"国家：%@", place.country);
                NSLog(@"城市：%@", place.locality);
                NSLog(@"区：%@", place.subLocality);
                NSLog(@"街道：%@", place.thoroughfare);
                NSLog(@"子街道：%@", place.subThoroughfare);
            }
        }];

        NSLog(@"@@@@@@@@@@=====%f,%f",lati,longti);
