This section describes adding C1MaskedTextField controls to an iOS application for specifying four input fields, namely ID, Date of Birth, Phone, and State. The ID input field accepts a nine-digit number separated by hyphens, the Date of Birth field accepts a date in mm/dd/yyyy format, the Phone field accepts a 10-digit number with area code, and the State field accepts abbreviated postal code of a state.

The following image shows the input fields configured after completing the above steps.

Add the following code in ViewDidLoad method to display C1MaskedTextField controls.

public override void ViewDidLoad()
   {
        base.ViewDidLoad();

        MaskedID.Mask = "000-00-0000";
        MaskedDOB.Mask = "90/90/0000";
        MaskedPhone.Mask = "(999) 000-0000";
        MaskedState.Mask = "LL";
                
        this.View.Add(MaskedID);
        this.View.Add(MaskedDOB);
        this.View.Add(MaskedPhone);
        this.View.Add(MaskedState);
      }
