uitableview

问题 I've read in another thread on SO that you can adjust the font or background colour of the index bar (that is the A-Z # scrollbar) in a UITableView adding a CALayer. My app will be running on iOS 5 and above and since I haven't seen anything about this in the Apple docs, would it be right to say that it simply isn't possible without creating a custom table view?

问题 I'm having some trouble trying to change the background of a UITableView with groups. _tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"tableViewBg.png"]]; This usually works on every other UITableView, but not the one with groups, is there something else I have to do?

问题 I inserted a tableview inside a UIViewController. But my code is not working.

问题 I have a tableview and navigation bar on the top. I have a Edit button on the left of my navigation bar with the following line of code. self.navigationItem.leftBarButtonItem = self.editButtonItem; When i click on the edit button, it changes to done button. All is fine so far.
