先导入
然后在 info.plist 文件中添加 Privacy - Location Always and When In Use Usage Description 和 Privacy - Location When In Use Usage Description 两个就可以了。
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
我要评论#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];
// 精确度
[_locManager setDesiredAccuracy:kCLLocationAccuracyBest];
// 精确到米
_locManager.distanceFilter = 100;
_locManager.delegate = self;
if (![CLLocationManager locationServicesEnabled]) { // 判断当前服务是否开启
NSLog(@"开启定位服务");
} else {
// 当前状态
CLAuthorizationStatus status = [CLLocationManager authorizationStatus];
if (status == kCLAuthorizationStatusNotDetermined) { // 未选中状态时候
[_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;
// 开始定位
[self.locManager startUpdatingLocation];
}
@end
调用方法：
[[LocationManager shareManager] getGps:^(NSString *lat, NSString *lon) {
NSLog(@"%@, %@", lat, lon);
}];
