Add UIScrollView with Paging to Existing UIViewController

Question

I\'m wanting to add a UIScrollView with paging to go through different views from my existing view controller which is the root view of my app. I also have tab bar and navi

This works really well for me:

Declare a property for your UIScrollView, and set your ViewController as a UIScrollViewDelegate

@interface ViewController : UIViewController

@property (strong, nonatomic) UIScrollView *theScrollView;

@end

**Note that I'm setting up my UIScrollView with code, but it can easily be done with a XIB.

In viewDidLoad: of your ViewController

    self.theScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 50, self.view.frame.size.width, 300)];
    self.theScrollView.delegate = self;
    self.theScrollView.pagingEnabled = YES;
    self.theScrollView.showsHorizontalScrollIndicator = NO;     
    self.theScrollView.showsVerticalScrollIndicator = NO;
    [self.view addSubview:self.theScrollView];

    NSArray *viewArray = [NSArray arrayWithObjects://your UIViews];

    for(int i=0; i

Most paging scrollViews also have a UIPageControl associated with it. To do that, override this UIScrollViewDelegate method:

- (void)scrollViewDidScroll:(UIScrollView *)sender {
    CGFloat pageWidth = self.theScrollView.frame.size.width;
    int page = floor((self.theScrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
    self.thePageControl.currentPage = page;
}
