iPhone：如何在选项卡视图中添加可滚动文本

Question

Looking for some guidance.

In my main window nib file, i have a tab controller where each tab control item is being loaded by a separate nib file and controller. One of the tab items is being loaded by a navigation controller. Looks like this (excuse me for not including screenshot)

• MainWindow.xib
  • Windows
  • UITabBarController
    • UITabBar
    • UINavigationController (loaded from Test.xib file)
      • TabBar Item
• Test.xib
  • View

Now I like to add a scrollable text in the Test.xib. So that when the user clicks on the tab item, my Test view opens up with some text that the user can scroll.

Do I need to add a UITextView as a child of my View in Test.xib? Do I need to add a UIScrollableView? And how would I connect them all so that I can manage the text.

Answer 1

Yes, UITextView needs to be a child of your View in Test.xib (you can add it programatically if you like or through IB). You do not need a UIScrollableView. The textview will scroll as long as you set scrollEnabled = YES;

Not sure what you mean by "how would I connect them so I can manage the text". You can send the UITextView a message of setText to whatever text you want in there. Hope that helps some!

Answer 2

If you add an UITextView to your view, connect it to a proper Outlet in your controller, than you can manipulate the text with setText: . The scrolling behaviour is added automatically.
