我想添加一个带有分页的 UIScrollView 以浏览来自我现有视图控制器的不同视图,这是我的应用程序的根视图。我也有标签栏和导航栏控制器。我可以向这个视图控制器添加一个滚动视图来完成我想要的,如果是这样,有人可以指出我如何去做吗?

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

@interface KFBViewController ()
{

}

@end

@implementation KFBViewController

这对我来说非常有效:

为您声明一个属性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UIScrollView的代码,但可以使用 XIB 轻松完成。

viewDidLoad:您的 ViewController 中

    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与之关联的。为此,请覆盖此UIScrollViewDelegate方法:

- (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;
}

此链接对您有所帮助。这里使用了页面控制器和滚动视图 -

我可能会尝试使用UIPageViewController,而不是常规的分页滚动视图。

Apple 的PhotoScroller 示例代码提供了一个很好的示例来说明如何使用UIPageViewController.

我在 github 上也有一些代码可以修改 PhotoScroller 以加载UIPageViewController内部UIViewController子类。(在 Apple 的示例代码中,UIPageViewController是根视图控制器。)

我从来没有在每个页面中使用UIPageViewController带有不同UIViewController子类的 a(PhotoScroller 示例代码PhotoViewController在所有页面中都使用 s),但我不明白为什么不能通过对代码进行一些修改来完成它。
