如何将静态单元格链接到 Outlet/Actions - 例如点击呼叫单元以呼叫号码

Question

我的代码。顺便说一句，我无法接听上班电话，网站也打不开！

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *urlToOpen = @"";
if( indexPath.section == 0 ){
    // call number
    urlToOpen = @"tel:442074036933";
} else if( indexPath.section == 1 ){
    // open website
    urlToOpen = @"http://www.designmuseum.org";
} else {
    // open address

    urlToOpen = @"http://maps.apple.com/maps?daddr=Design+Museum+London";
}
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlToOpen]];
NSString *destinationAddress = [NSString stringWithFormat:@"%@+%@+%@",
                                [address street],
                                [address city],
                                [address country]];

NSString *sourceAddress = [LocalizedCurrentLocation currentLocationStringForCurrentLanguage];

NSString *url = [NSString stringWithFormat:@"http://maps.apple.com/maps?saddr=%@&daddr=%@",
                 [sourceAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
                 [destinationAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];

我需要为我的应用添加目的地地址 = 28 Shad Thames, London, United Kingdom。用什么格式写？因为我无法让它工作，真的需要快速解决我的应用程序的这个问题

您不需要为每个单元创建插座。

你的 didSelectRowAtIndexPath 方法被调用了吗？

那么你可以这样做：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *urlToOpen = @"";
    if( indexPath.section == 0 ){
        // call number
        urlToOpen = @"tel:12125551212";
    } else if( indexPath.section == 1 ){
        // open website
        urlToOpen = @"http://www.google.nl";
    } else {
        // open address
            NSString *destinationAddress = @"Amsterdam";

            Class itemClass = [MKMapItem class];
            if (itemClass && [itemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)]) {

                CLGeocoder *geocoder = [[CLGeocoder alloc] init];
                [geocoder geocodeAddressString:destinationAddress completionHandler:^(NSArray *placemarks, NSError *error) {
                    if([placemarks count] > 0) {

                        MKPlacemark *placeMark = [[MKPlacemark alloc] initWithPlacemark:[placemarks objectAtIndex:0]];

                        MKMapItem *mapItem = [[MKMapItem alloc]initWithPlacemark:placeMark];

                        MKMapItem *mapItem2 = [MKMapItem mapItemForCurrentLocation];


                        NSArray *mapItems = @[mapItem, mapItem2];

                        NSDictionary *options = @{
                                        MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving,
                                        MKLaunchOptionsMapTypeKey:
                                        [NSNumber numberWithInteger:MKMapTypeStandard],
                                        MKLaunchOptionsShowsTrafficKey:@YES
                        };

                        [MKMapItem openMapsWithItems:mapItems launchOptions:options];

                    } else {
                        //error nothing found
                    }
                }];
                return;
            } else {

                NSString *sourceAddress = [LocalizedCurrentLocation currentLocationStringForCurrentLanguage];

                urlToOpen = [NSString stringWithFormat:@"http://maps.google.com/maps?saddr=%@&daddr=%@",
                             [sourceAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
                             [destinationAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
            }
    }
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlToOpen]];
}

indexPath.section 也可以是 indexPath.row，这取决于您制作 tableView 的方式。

编辑： 我添加了“获取路线”部分。这将检查它是 ios5 还是 ios6。

对于 ios5，我使用这篇文章中的 LocalizedCurrentLocation http://www.martip.net/blog/localized-current-location-string-for-iphone-apps

对于 ios6，我使用 CLGeocoder 获取地标，然后用它和当前位置打开地图。

记得添加CoreLocation.framework和MapKit.framework
