Question

谷歌地图应用程序有“到这里的方向”和“从这里开始的方向”，如http://static.intomobile.com/wp-content/uploads/2008/10/iphone-22-os-google-maps-street-view-23.png

当我拨打联系页面时，我可以在地址簿的信息页面添加“到这里的路线”按钮吗？

ABAddressBookRef addressBook = ABAddressBookCreate();
NSArray *allPeople = (NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
ABRecordRef person = ABAddressBookGetPersonWithRecordID(addressBook, (ABRecordID) iRecordNo);

ABPersonViewController *personController = [[ABPersonViewController alloc] init];

personController.addressBook = addressBook;
personController.displayedPerson = person;
personController.allowsEditing = YES;       

[self.navigationController pushViewController:personController animated:YES];

[personController release];

"http://maps.google.com/maps?daddr=%f,%f&saddr=%f,%f",userLatitude,userLongitude,targetLatitude,targetLongitude


-(void)goToMaps{

[[UIApplication sharedApplication]openURL:url];//the url i gave you above
NSLog(@"the URL for directions is %@", [url absoluteString]);

}
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {

if (indexPath.row == x) {//whatever row in the table it is on
    [self goToMaps];
}

}

如何将“路线到这里”按钮添加到地址簿中？
