how to use UISegmentedControl to change datasource in tableview? with sql tables or read data from arrays 开发者_开发知识库 thanks

1. Use -addTarget:action:forControlEvents: (with events UIControlEventValueChanged) to set up a response action for the segmented control.
2. In the action, check the sender's selectedSegmentIndex property. Use this to determine which data source to use.
3. Change the table view's dataSource property.
