UISegmentedControl 在 uitableviewcontroller 中切换视图

Question

我有以下场景：

UITabBarController
--tab1
--tab2
----UINavigationController (with a UITableViewController and 3 rows)
------pushedViewController
--tab3
--tab4
--tab5

好的，所以，当用户单击 UINavigationViewController 中的一个选项时，它会推送“pushedViewController”，并且在该视图控制器中，我希望有一个分段控件，就像 App Store 上的那个 http://i.stack.imgur.com/hrdxL.png

我该怎么做？

我已经检查过了

这可以帮助我，但我不知道如何 Switch between UIViewControllers using UISegmentedControl

这个用户也问了同样的问题，但没有完整的代码 Recreating Segmented Control from iPhone App Store

pushViewController 可以包含一个 UIScrollView 以填充屏幕。设置分页启用，并给它三个大的子视图，像这样：

CGFloat width = self.view.bounds.width;
CGFloat height = self.view.bounds.height;

// it's easier to do all this this in xib/storyboard, but to illustrate...

self.scrollView.frame = CGRectMake(0,0,width,height);
self.scrollView.contentSize = CGSizeMake(width*3.0, height);  // this must be done in code
self.scrollView.pagingEnabled = YES;

UIView *subviewA, *subviewB, subviewC;

subviewA.frame = CGRectMake(0.0, 0.0, width, height);
subviewB.frame = CGRectMake(0.0, width, width, height);
subviewB.frame = CGRectMake(0.0, 2.0*width, width, height);

[self.scrollView addSubview:subviewA];
[self.scrollView addSubview:subviewB];
[self.scrollView addSubview:subviewC];

// then when the segmented control changes ...

- (IBAction)segmentedControlChanged:(UISegmentedControl *)sender {

    NSInteger page = sender.selectedSegmentIndex;
    CGFloat contentOffsetX = page*self.view.bounds.width;
    [self.scrollView setContentOffset:CGPointMake(contentOffsetX, 0.0) animated:YES];
}
