I created a project with Tabbar template. The First View of my Tabbar project

  • 0

I created a project with Tabbar template. The First View of my Tabbar project just wants the same function of the TTCatalog sample project. The Second View will integrate a Map function.

I integrate some code from TTCatalog sample project to do so. But when my App starts, only an empty tableview displayed in my first view. It’s just a white table with some empty rows. nothing else.

When I quit my App from emulator, and start it again from emulator,first I can see a table view like that of TTCatalog ( with blue titles and labels), But soon the table view is covered with an empty table view.

Please help

thanks

    There is no need to inherit CatalogController, if the only thing you need is a tableView inside a tabBarController then there is even no need to use three20 at all. To get started I would recommend you use a simpler approach. While three20 and the TTTableViewController can help a lot with a certain kind of setups, it is not the general best way to do things.

    Let your FirstViewController inherit from UITableViewController, implement the UITableViewDataSource methods. If you are experiencing problem or need with a specific problem feel free to ask here.

    If you got this working and you really need something that three20 can help you achieve, read through the TTTableViewController sources, TTModel, TTTableViewDataSource, find a tutorial and go on.

    Maybe this question may help you: Three20's URL-based navigation + tab bar example? especially this link: http://three20.pypt.lt/url-based-navigation-and-state-persistence
