Objective-C iOS如何將UIPageControl添加到我的CollectionView？

Question

我有一個帶有pagedEnable和水平滾動的collectionView。 我只想在滾動時將pageControl的點添加到我的collectionView中。

Answer 1

如下實現滾動視圖的委託方法： -

說collectionViewTestimonial：名稱您的收藏視圖（IBOutlet中），pageControlTestimonial：頁面控件的名稱

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView 
{ 
    CGFloat pageWidth = collectionViewTestimonial.frame.size.width; 
    pageControlTestimonial.currentPage = collectionViewTestimonial.contentOffset.x/pageWidth; 
} 

Answer 2

嘗試這樣的：

-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{ 
// Suppose your collectionview cell width is equal to your screen size 
CGFloat collectionViewCellWidth = self.view.frame.size.width;  
_pageControl.currentPage = (scrollView.contentOffset.x/collectionViewCellWidth); 
} 

Answer 3

設置頁面頁數控制

NSUInteger numberOfCells = 10; 
_pageControl.numberOfPages = numberOfCells; 

實現滾動視圖的委託方法

-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{ 
// Suppose your collectionview cell width is equal to your screen size 
CGFloat collectionViewCellWidth = self.view.frame.size.width;  
_pageControl.currentPage = (scrollView.contentOffset.x/collectionViewCellWidth); 
}
