How do I use the Question and Password Dialogues in iOS?
This lesson describes how to use the LiveCode Question and Password Dialogues in iOS. Source code and screen captures are provided.
The Question and Password Dialogues provide simple pop up windows that allow you to prompt the user for the answer to a question or a password. The keyboard is raised at the same time as a dialogue is displayed. This allows the user to enter the required information.
Creating the Question Dialogue
The Question Dialogue is raised using the ask question syntax that is demonstrated in the following example:
ask question "What Time is it:" with "10:00" titled "Time Check"
Observe how the respective areas of the dialogue are populated with the values specified in the ask command. The default result is shown in gray, indicating to the user what the default value is and that an answer has not yet been provided.
Responding to the Question Dialogue
Creating the Password Dialogue
The Password Dialogue is raised using the ask password syntax that is demonstrated in the following example:
ask password "Please log in:" with "Your Password" titled "System Password"
The respective dialogue areas are populated in the same way for the Question Dialogue as for the Password Dialogue. The default result is also shown in gray, indicating to the user what the default value is and that an answer has not yet been provided. As the default value is not concealed, it should ideally not be a valid password, but may be some kind of message requesting the user to enter the password.
