iOS Generate UI by parsing xml using NSXMLParser

[Knight Rider]

Hi,
I can parse the XML file using NSXMLParser. I can get the tags and the attributes....
But my XML has tags like <Textfield>,<Label>,<Picker>..
I have to bring these controls dynamically on view...

And I have to display different view after getting a <Page> tag..
How to display a different view?

Is there any Tutorial for this..?

Thanx in advance

Hi, In the following XML, I can display controls (textfield,buttons,labels) dynamically on view according to XML tags... I am using NSXMLParser..

The XML is like this.....

<Text></Text>
< /Ctl>
< /row>



< row index="2">
< Ctl type="Label" name="lblPassword">
< loc pos="Left">
</loc>
< text>Password< /text>
< /Ctl>

< Ctl type="TextBox" name ="txtPassword">

I can display Username,Password labels by creating them dynamically using self.view

But After Authentication To display FAQ page,I need to load another view (Or clear current view...) How to generate Labels on next view ? As I cant use self.view

Any suggestions...newbie here.. Thanx in advance..

You just have to make a good program logic. Where exactly you have a problem? What can't you do when you already parse the XML file?

Generate different views using xml parsing

Thanks for reply...

I can display labels and textbox on first page..
I am creating label as soon as I get <label> tag...Using self.view...
[I am not parsing the XML in different class].

So, when next <page> tag comes, if I load another view then how to Create and displaY LABEL...
I cant use self.view...

It may be using controllers and data passing between Views..
But I dont know how to do it...

Plz Help.
