示例代码:
#import "ViewController.h"
#import <MapKit/MapKit.h>
@interface ViewController ()
// 目标地址
@property (weak, nonatomic) IBOutlet UITextField *destination_TF;
@end
@implementation ViewController
// 开始导航按钮点击事件
- (IBAction)navgationBtnClick:(UIButton *)sender {
// 将起点和重点传递给系统地图
// 1.获取起点和终点
// 起点: 当前定位点
MKMapItem *sourceItem = [MKMapItem mapItemForCurrentLocation];
// 终点: 手动输入的地址 地理编码
CLGeocoder *geocoder = [[CLGeocoder alloc]init];
[geocoder geocodeAddressString:self.destination_TF.text completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
if (placemarks.count == 0 || error) {
return ;
}
CLPlacemark *clPlacemark = placemarks.lastObject;
MKPlacemark *mkPlacemark = [[MKPlacemark alloc]initWithPlacemark:clPlacemark];
MKMapItem *destinItem = [[MKMapItem alloc]initWithPlacemark:mkPlacemark];
// 2.打开地图
[MKMapItem openMapsWithItems:@[sourceItem,destinItem] launchOptions:@{MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsMapTypeKey:@0}];
}];
}
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
