将具有分页功能的 UIScrollView 添加到现有 UIViewController

我想添加一个带有分页功能的 UIScrollView 来浏览现有视图控制器（我的应用程序的根视图）中的不同视图。我还有标签栏和导航栏控制器。我可以向该视图控制器添加一个滚动视图来完成我想要的事情吗？如果是这样，有人可以为我指明如何去做的正确方向吗？

这是我的视图控制器。

#import "KFBViewController.h"
#import "ListViewController.h"
#import "ActionAlertsViewController.h"
#import "MarketUpdatesViewController.h"
#import "AgStoriesViewController.h"
#import "KFBNewsViewController.h"
#import "MemberBenefits.h"

#import "WebViewController.h"
#import "YouTubeView.h"
#import "KFBFlickrViewController.h"
#import "RSFM.h"
#import "UAPush.h"
#import "TUSafariActivity.h"

@interface KFBViewController ()
{

}

这对我来说非常有效：

为您申报财产UIScrollView，并将您的 ViewController 设置为UIScrollViewDelegate

@interface ViewController : UIViewController<UIScrollViewDelegate>

@property (strong, nonatomic) UIScrollView *theScrollView;

@end

**请注意，我正在设置我的UIScrollView可以使用代码，但可以使用 XIB 轻松完成。

In viewDidLoad:你的ViewController的

    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<viewArray.count; i++)
    {
        CGRect frame;
        frame.origin.x = self.theScrollView.frame.size.width * i;
        frame.origin.y = 0;
        frame.size = self.theScrollView.frame.size;

        UIView *subview = [[UIView alloc] initWithFrame:frame];
        [subview addSubview:[viewArray objectAtIndex:i]];
        [self.theScrollView addSubview:subview];
    }

    self.theScrollView.contentSize = CGSizeMake(self.theScrollView.frame.size.width * viewArray.count, self.theScrollView.frame.size.height);

大多数分页滚动视图也有一个UIPageControl与之相关。为此，请覆盖此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;
}
