iphone - 如何使用 UIPageControl 从一个视图导航到另一个视图？

Question

我有页面控制但没有导航到其他视图。所以请提供解决方案。

    pageControl=[[UIPageControl alloc] initWithFrame:CGRectMake(0,380,320,40)];
    pageControl.backgroundColor=[UIColor clearColor];
    pageControl.userInteractionEnabled =YES;
    [pageControl addTarget:self action:@selector(pageAction:) forControlEvents:UIControlEventValueChanged];

    [pageControl setHighlighted:YES];


-(void)pageAction:(UIPageControl*)control
{       
    [self displayNextPage];
    [self displayPreviousPage];
}

谢谢你，马丹·莫汉。

Answer 1

希望这可以帮助：

-(void)pageAction:(UIPageControl*)control
{       
int page = pageControl.currentPage;
CGRect frame = pagingScrollView.frame;
frame.origin.x = (myScrollView.frame.size.width * page);
[myScrollView scrollRectToVisible:frame animated:YES];
}

斯威夫特：

       func changeImageOnPageControl(sender: UIPageControl) {
            let page = sender.currentPage;
            var frame = self.scrollViewBase.frame;
            frame.origin.x = self.scrollViewBase.frame.size.width * CGFloat(page);
            self.scrollViewBase.scrollRectToVisible(frame, animated: true);

        }
