ios - 如何在 iOS 9 中使用 Apple maps on objective-c？

Question

我正在使用此代码进行苹果 map 集成。

CLLocationCoordinate2D rdOfficeLocation ;

//Apple Maps, using the MKMapItem class

MKPlacemark *placemark = [[MKPlacemark alloc] initWithCoordinate:rdOfficeLocation addressDictionary:nil];
MKMapItem *item = [[MKMapItem alloc] initWithPlacemark:placemark];
       // NSLog(@"val is %@",placemark);
        //item.name = @"ReignDesign Office";
[item openInMapsWithLaunchOptions:nil];

上面的代码放在 viewDidLoad 方法中是这样的。

但我希望用户在地址显示的搜索栏中输入位置，然后如何在 NSLOG

中获取地址

如果我们想通过手势选择位置，如何获取地址位置和纬度、经度值。

如果有人知道这个过程，请告诉我。

您必须根据需要使用 google place search API。首先，您必须从谷歌开发者控制台获取 API key 。并使用下面的 URL 获取搜索位置 https://maps.googleapis.com/maps/api/place/autocomplete/json?input=Vict&types=geocode&language=fr&key=YOUR_API_KEY

从 Github 下载库

步骤 1) 首先在您的 viewController.h 中的 @interface class 之前添加 class @class SPGooglePlacesAutocompleteQuery;>>>>>>>

#import <UIKit/UIKit.h>

@class SPGooglePlacesAutocompleteQuery;

@interface ViewController : UIViewController
{
    SPGooglePlacesAutocompleteQuery *searchQuery;
}
@property (nonatomic,strong) NSMutableArray *mutArrSearchData;

@end

然后是你的 viewDidLoad >>>

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    self.mutArrSearchData = [NSMutableArray array];

    searchQuery = [[SPGooglePlacesAutocompleteQuery alloc] init];
    self.mutArrSearchData = [NSMutableArray array];

}

step-2) 然后如果你使用的是 UISearchBar 然后设置委托(delegate)并添加委托(delegate)方法。对于 EX:

- (void)searchBar:(UISearchBar *)searchBar
    textDidChange:(NSString *)searchText{

    if (searchBar.text.length>=1) {
        [self handleSearchForSearchString:sender.text];
    }
}

- (void)handleSearchForSearchString:(NSString *)searchString {
    [self.mutArrSearchData removeAllObjects];
    searchQuery.location = self.mapView.userLocation.coordinate;
    searchQuery.input = searchString;
    [searchQuery fetchPlaces:^(NSArray *places, NSError *error) {
        if (error) {
            SPPresentAlertViewWithErrorAndTitle(error, @"Could not fetch Places");
        } else {

//            you have got your related responce in this array
            [self.mutArrSearchData addObjectsFromArray:places];
            NSLog(@"responce:%@",self.mutArrSearchData);

            //[self.tableview reloadData];
        }
    }];
}

你在 up 方法中得到了响应。现在您可以在您的表格 View 中分割这个响应。和 didSelect 方法....

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    yourCell *aCell;

    [aCell.yourLbl.text setText:[self placeAtIndexPath:indexPath].name];
    return aCell;
}

// Called after the user changes the selection.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    SPGooglePlacesAutocompletePlace *place = [self placeAtIndexPath:indexPath];
    [place resolveToPlacemark:^(CLPlacemark *placemark, NSString *addressString, NSError *error) {
        if (error) {
            SPPresentAlertViewWithErrorAndTitle(error, @"Could not map selected Place");
        } else if (placemark) {

            // your selected placemark here. get data from placemark which you needed.

        }
    }];
}

- (SPGooglePlacesAutocompletePlace *)placeAtIndexPath:(NSIndexPath *)indexPath {
    return [self.mutArrSearchData objectAtIndex:indexPath.row];
}

make sure to get API_KEY from google developer Console.

希望对你有帮助。
