Question

我设法恢复了下面代码中指定的所有信息，但我无法检索user.location的纬度和经度。

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user {
        NSString *fbUsername = [NSString stringWithFormat:@"%@",user.username];
        NSString *fbNickname = [NSString stringWithFormat:@"%@",user.name];
        NSString *fbName = [NSString stringWithFormat:@"%@",user.first_name];
        NSString *fbSurname = [NSString stringWithFormat:@"%@",user.last_name];
        NSString *fbLocation = [NSString stringWithFormat:@"%@",user.location.name];
}

请帮助我！

Answer 1

要获取用户的经度和经度，请在您发布的方法中尝试：

NSNumber *userLatitude = user.location.location.latitude;
NSNumber *userLatitude = user.location.location.latitude;
//do whatever you want with the values here

     - (void)placePickerViewControllerSelectionDidChange:(FBPlacePickerViewController *)placePicker
 {
// id&#060;
 // FBGraphPlace&#062;
 place = placePicker.selection;


 // we'll use logging to show the simple typed property access to place and location info
 NSLog(@"place=%@, city=%@, state=%@, lat long=%@ %@",
 place.name,
 place.location.city,
 place.location.state,
 place.location.latitude,
 place.location.longitude);
 }
