问题描述
谷歌地图应用程序有到这里的方向和从这里开始的指示，如
Google Map App has "directions to here" and "directions from here" like 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？
When I call contact page, can I add "directions to here" button into the info page of address book?
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];
推荐答案
"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];
}
}
