MKMapItem 到 TableView

Question

我正在尝试将位置搜索列表显示到 TableView 中，首先这可能吗？

如果可以，我该怎么办？

我收集列表的代码是：

MKLocalSearchRequest *searchRequest = [[MKLocalSearchRequest alloc] init];
[searchRequest setNaturalLanguageQuery:@"Cafe"];

CLLocationCoordinate2D userCenter = CLLocationCoordinate2DMake(48.8566, 2.3522);
MKCoordinateRegion userRegion = MKCoordinateRegionMakeWithDistance(userCenter, 15000, 15000);
[searchRequest setRegion:userRegion];

MKLocalSearch *localSearch = [[MKLocalSearch alloc] initWithRequest:searchRequest];
[localSearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) {

    if (!error) {
        NSMutableArray *gLoc = [NSMutableArray array];
        for (MKMapItem *mapItem in [response mapItems]) {
            [gLoc  addObject:mapItem.placemark];
            NSLog(@"Name: %@, Placemark title: %@", [mapItem name], [[mapItem placemark] title]);

在上面的示例中，我在巴黎搜索 "Cafe"，并将信息存储到名为 gLoc 的数组中。

内容：

NSLog(@"Name: %@, Placemark title: %@", [mapItem name], [[mapItem placemark] title]);

是所有位置的完整列表，格式为：

Name: Strada Café, Placemark title: 94 Rue du Temple, 75003 Paris, France

内容：

NSLog(@"%@",  gLoc);

是所有位置格式如下的数组：

"Strada Caf\U00e9, 94 Rue du Temple, 75003 Paris, France @ <+48.86220020,+2.35731150> +/- 0.00m, region CLCircularRegion (identifier:'<+48.86220020,+2.35731150> radius 49.91', center:<+48.86220020,+2.35731150>, radius:49.91m)",

我不知道如何继续。我希望将这些信息理想地转换为名称作为标题和地址作为副标题，有没有办法以这种方式操作数据来实现这一点？

试试下面的代码：

#import "ViewController.h"

@interface ViewController () <UITableViewDataSource, UITableViewDelegate>

@end

@implementation ViewController
{
    NSMutableArray *gLoc;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    UITableView *tableView = [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain];
    tableView.delegate = self;
    tableView.dataSource = self;
    [self.view addSubview:tableView];

    // Do any additional setup after loading the view, typically from a nib.
    MKLocalSearchRequest *searchRequest = [[MKLocalSearchRequest alloc] init];
    [searchRequest setNaturalLanguageQuery:@"Cafe"];

    CLLocationCoordinate2D userCenter = CLLocationCoordinate2DMake(48.8566, 2.3522);
    MKCoordinateRegion userRegion = MKCoordinateRegionMakeWithDistance(userCenter, 15000, 15000);
    [searchRequest setRegion:userRegion];

    MKLocalSearch *localSearch = [[MKLocalSearch alloc] initWithRequest:searchRequest];
    [localSearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) {

        if (!error) {
            gLoc = [NSMutableArray array];
            for (MKMapItem *mapItem in [response mapItems]) {
                [gLoc  addObject:mapItem.placemark];
                NSLog(@"Name: %@, Placemark title: %@", [mapItem name], [[mapItem placemark] title]);
            }
            [tableView reloadData];
        }
    }];
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)theTableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)theTableView numberOfRowsInSection:(NSInteger)section
{
    return [gLoc count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle
                                      reuseIdentifier:cellIdentifier];
    }

    MKPlacemark *placemark = gLoc[indexPath.row];
    cell.textLabel.text = placemark.name;
    NSArray *lines = placemark.addressDictionary[ @"FormattedAddressLines"];
    cell.detailTextLabel.text = [lines componentsJoinedByString:@","];

    return cell;
}

#pragma mark - UITableViewDelegate

// when user tap the row, what action you want to perform
- (void)tableView:(UITableView *)theTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"selected %d row", indexPath.row);
}

结果：

MKMapItem 到 TableView

MKMapItem to TableView

objective-c

uitableview

mapkit
