ios – 如何将我当前的位置分享给UIActivityViewController？

我知道我可以将文本,URL,图像等内容添加到UIActivityViewController中,但是如何使用我的位置缩略图添加当前位置,如下面显示的推文中所示？换句话说,如何在UIActivityViewController中共享坐标“纬度,经度”？

谢谢

解决方法

我有一个完整的代码示例以及执行此操作的所有重要类/方法.我知道答案很晚,但这有助于将来的某些人：

- (void)shareTab
{
    PFGeoPoint *geoPoint = self.vidgeoObject[kParseLocation];
    Nsstring *coordinates = [Nsstring stringWithFormat:@"http://maps.apple.com/maps?q=%f,%f",geoPoint.latitude,geoPoint.longitude];
    CLLocation *userLocation = [[CLLocation alloc] initWithLatitude:geoPoint.latitude longitude:geoPoint.longitude];
    CLGeocoder *geocoder;
    geocoder = [[CLGeocoder alloc]init];

    [geocoder reverseGeocodeLocation:userLocation completionHandler:^(NSArray *placemarks,NSError *error)
    {
        CLPlacemark *rootPlacemark = placemarks[0];
        MKPlacemark *evolvedplacemark = [[MKPlacemark alloc]initWithPlacemark:rootPlacemark];

        ABRecordRef persona = ABPersonCreate();
        ABRecordSetValue(persona,kABPersonFirstNameProperty,(__bridge CFTypeRef)(evolvedplacemark.name),nil);
        ABMutableMultiValueRef multiHome = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);

        bool didAddHome = ABMultiValueAddValueAndLabel(multiHome,(__bridge CFTypeRef)(evolvedplacemark.addressDictionary),kABHomeLabel,NULL);

        if(didAddHome)
        {
            ABRecordSetValue(persona,kABPersonAddressproperty,multiHome,NULL);

            NSLog(@"Address saved.");
        }

        NSArray *individual = [[NSArray alloc]initWithObjects:(__bridge id)(persona),nil];
        CFArrayRef arrayRef = (__bridge CFArrayRef)individual;
        NSData *vcards = (__bridge NSData *)ABPersonCreateVCardRepresentationWithPeople(arrayRef);

        Nsstring* vcardString;
        vcardString = [[Nsstring alloc] initWithData:vcards encoding:NSASCIIStringEncoding];
        NSLog(@"%@",vcardString);


        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
        Nsstring *documentsDirectory = [paths objectAtIndex:0]; // Get documents directory

        Nsstring *filePath = [documentsDirectory stringByAppendingPathComponent:@"pin.loc.vcf"];
        [vcardString writetoFile:filePath
                              atomically:YES encoding:NSUTF8StringEncoding error:&error];

        NSURL *url =  [NSURL fileURLWithPath:filePath];
        NSLog(@"url> %@ ",[url absoluteString]);


        // Share Code //
        NSArray *itemsToShare = [[NSArray alloc] initWithObjects: url,nil] ;
        UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil];
        activityVC.excludedActivityTypes = @[UIActivityTypePrint,UIActivityTypecopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypeSavetoCameraRoll,UIActivityTypePostToWeibo];

        if (UI_USER_INTERFACE_IdioM()==UIUserInterfaceIdiomPhone)
        {
            [self presentViewController:activityVC animated:YES completion:nil];
        } else
        {
        popControl = [[UIPopoverController alloc] initWithContentViewController:activityVC];
        }

    }];

}
