How to add label inside ScrollView - objective-c

Question

I am a newbie to Xcode 5 and Objective C. I want to develop word processing app. Still, I can't figure how to do it with Xcode.
How do I add label inside ScrollView with swipe left to right direction: left to preview, right to next word?
How do I add 100 words to a UIlabel in Xcode?
For example, swiping right for next word, "Apple", then swiping right again for next word "Bananas"; Swiping left to preview: "Apple".

This is the behavior of UIScrollView paging. Here you can find documentation.
How can you add UILabel ( in general any instance on UIView ) to UIScrollView.
UIScrollView* scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds];
scrollView.pagingEnabled = YES; // replace default scroll with paging
for ( int i = 0; i < mWordsCount; i++ )
{
UILabel* textLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width * i, self.view.frame.size.height)];
textLabel.text = #"currnet word"; // wordsArray[i]; or [wordsArray objectAtIndex:i];
[scrollView addSubview:textLabel];
// Uncomment if you don't use ARC
//[textLabel release];
}
