獲取定位信息

先導入

然後在 info.plist 文件中添加 Privacy - Location Always and When In Use Usage Description 和 Privacy - Location When In Use Usage Description 兩個就可以了。

LocationManager.h

#import <Foundation/Foundation.h>

typedef void(^LocationBlock)(NSString *lat, NSString *lon);

@interface LocationManager : NSObject

+ (instancetype)shareManager;

- (void)getGps:(LocationBlock)block;

@property (nonatomic, copy) NSString *lat;
@property (nonatomic, copy) NSString *lon;

@end

LocationManager.m

#import "LocationManager.h"
#import <CoreLocation/CoreLocation.h>

@interface LocationManager ()<CLLocationManagerDelegate>

@property (nonatomic, strong) CLLocationManager *locManager;

@property (nonatomic, copy) LocationBlock block;

@end

@implementation LocationManager

+ (instancetype)shareManager {
    
    static LocationManager *_manager;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        
        _manager = [[LocationManager alloc] init];
    });
    return _manager;
}

- (instancetype)init {
    
    if (self = [super init]) {
        
        _locManager = [[CLLocationManager alloc] init];
        // 精確度
        [_locManager setDesiredAccuracy:kCLLocationAccuracyBest];
        // 精確到米
        _locManager.distanceFilter = 100;
        _locManager.delegate = self;
        
        if (![CLLocationManager locationServicesEnabled]) { // 判斷當前服務是否開啟
            
            NSLog(@"開啟定位服務");
        } else {
            // 當前狀態
            CLAuthorizationStatus status = [CLLocationManager authorizationStatus];
            if (status == kCLAuthorizationStatusNotDetermined) { // 未選中狀態時候
                
                [_locManager requestWhenInUseAuthorization];
            }
        }
    }
    return self;
}

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation {
    
    CLLocationCoordinate2D coor = newLocation.coordinate;
    
    NSString *lat = [NSString stringWithFormat:@"%@", @(coor.latitude)];
    NSString *lon = [NSString stringWithFormat:@"%@", @(coor.longitude)];
    
    [LocationManager shareManager].lat = lat;
    [LocationManager shareManager].lon = lon;
    
    self.block(lat, lon);
    
    // 停止定位
    [self.locManager stopUpdatingLocation];
}

- (void)getGps:(LocationBlock)block {
    
    self.block = block;
    // 開始定位
    [self.locManager startUpdatingLocation];
}

@end

調用方法：

[[LocationManager shareManager] getGps:^(NSString *lat, NSString *lon) {
        
        NSLog(@"%@, %@", lat, lon);
    }];
