iOS：使用ABUnknownPersonViewController

Question

大家好，

我使用 LocationManager，Geocoder和Placemark 来获取用户的地址。一切正常。

启动standardUpdates后，我使用以下函数：

[...]

 -(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {

    CLLocation* location = [locations lastObject];
    [self.geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {

    if (error == nil && [placemarks count] > 0) {
        self.placemark = [placemarks lastObject];

    NSString *placemarkCountry = self.placemark.country;
    NSString *placemarkPostalCode = self.placemark.postalCode;
    NSString *placemarkAdministrativeArea = self.placemark.administrativeArea;
    NSString *placemarkLocality = self.placemark.locality;
    NSString *placemarkThoroughfare = self.placemark.thoroughfare;
    NSString *placemarkSubThoroughfare = self.placemark.subThoroughfare;

    [...] //here I'm displaying the address, nothing special

}

现在我想使用 ABUnknownPersonViewController 和 AddressBookUI 将地址添加到新的或现有的联系人。

-(IBAction)addAddressToContactButtonPressed {

    [...]

}

下图显示了它应该是什么样的：

问题： 函数 addAddressToContactButtonPressed 应该如何？你能帮帮我吗？该函数应使用NSStrings placemarkCountry，placemarkPostalCode，...并打开带有这些信息的ABUnknownPersonViewController。用户应使用此地址创建新联系人，或将此地址添加到现有用户。

我找了一些教程，但找不到任何有用的（对我有用）帮助。我是一个通过寻找教程学习的人，现在我被卡住了。

Thank you for your help and your answers.
:-)

Answer 1

1. 制作一个ABUnknownPersonViewController。给它一个代表。

2. 创建一个ABPerson。为ABPerson（ABRecord）分配您希望它拥有的任何功能：在本例中为地址。

3. 将ABPerson设为ABUnknownPersonViewController＆＃39; s Dim startDate As DateTime Dim endDate As DateTime If Not DateTime.TryParse(TextBox2.Text, startDate) Then ' there was an error parsing - do something useful startDate = New DateTime(2000, 1, 1) End If If Not DateTime.TryParse(TextBox3.Text, endDate) Then ' there was an error parsing - do something useful endDate = New DateTime(2100, 12, 31) Else ' add a day to include it in the range selected in the SQL query endDate = endDate.AddDays(1) End If Dim query As String = "SELECT inDate1, inTime1 FROM loginlog WHERE personID = @PersonID AND inDate1 BETWEEN @StartDate AND @EndDate" Dim mycon As New OleDbConnection(con) Dim command As New OleDbCommand(query, mycon) command.Parameters.Add(New OleDbParameter With {.ParameterName = "@PersonID", .OleDbType = OleDbType.VarWChar, .Value = TextBox1.Text}) command.Parameters.Add(New OleDbParameter With {.ParameterName = "@StartDate", .OleDbType = OleDbType.Date, .Value = startDate}) command.Parameters.Add(New OleDbParameter With {.ParameterName = "@EndDate", .OleDbType = OleDbType.Date, .Value = endDate}) ' now execute the query... 。

4. 将ABUnknownPersonViewController推送到现有的UINavigationController。
