一个

1.使用简单

2.高度自定义

3.两种使用方法

的视差滚动框架

it's a easy-to-use / highly customize / two way to use parallax effects framework.

安装 Installation


pod 'KYParallaxView', '~> 1.0.2'


本框架有两种使用场景:

Two situations to use this framework:

1、如果你不需要使用水平滚动的框架,只需要使用效果图中单页垂直滚动效果,那么你只需在你的ViewController中。

If you just wanna use the single vertical scroll view,you should:

    KYParallaxVerticalView *parallaxVerticalView= [[KYParallaxVerticalView alloc]initWithFrame:self.view.frame];
    [self.view addSubview:parallaxVerticalView];
    [parallaxVerticalView bkgImageViewSetImage: [UIImage imageNamed:@"[email protected]"]];// 指定背景图
就可以了。

That's it!

2、如果你需要使用整个框架,那么你需要在你的ViewController中:

 If you wanna use the whole framework.
  KYParallaxHorizontalView *parallaxHorizontalView = [[KYParallaxHorizontalView alloc]initWithFrame:self.view.frame andCollectionDelegate:self];
  [self.view addSubview:self.parallaxHorizontalView];
  • 然后实现UICollectionDataSource的协议方法:

    Then implement the UICollectionDataSource's protocol method:

#pragma mark -- UICollectionDataSource
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{

    return 5;

}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    KYParallaxCollectionCell *cell = (KYParallaxCollectionCell *)[collectionView dequeueReusableCellWithReuseIdentifier:@"HorizontalParallexCell" forIndexPath:indexPath];

    /*****自定义cell视图*****/
    /*****Custom the vertical scrollview content******/
    //设置每个单页的背景图片 Set the background img of every vertical scrollview
    [cell.verticalView bkgImageViewSetImage:[UIImage imageNamed:[NSString stringWithFormat:@"bkgImg_%ld.jpg",(long)indexPath.item+1]]];
    cell.verticalView.customView.label.text = [NSString stringWithFormat:@"%ld",(long)indexPath.item+1];
    cell.verticalView.customView.avatar.image = [UIImage imageNamed:[NSString stringWithFormat:@"kitten_%ld",(long)indexPath.item+1]];
    cell.verticalView.customView.pic.image = [UIImage imageNamed:[NSString stringWithFormat:@"l%ld.jpg",indexPath.item+1]];
    cell.verticalView.scroller.contentOffset = CGPointMake(0, 0); //解决cell同时复用scrollview位置的bug  Fix resuing the contentOffset of cell

    //...

    return cell;

}
  • 最后你还需要实现UIScrollViewDelegate中的scrollViewDidScroll方法:

    Lastly,you should mplement the UIScrollViewDelegate's protocol method

#pragma mark -- UITableViewDelegate
- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
    [self.parallaxHorizontalView parallax:scrollView];
}

3.如何自定义单页滚动视图内容?

How to customize the vertical scroll view's  content?
  • 你会发现有三个文件. there are three files.

  • 你会发现CustomViewXib是这样的:

    So you can customize your content in the xib.

  • 是的,你可以在这里可视化布局你想要的滚动界面的内容。当然,为了方便自定义内容你还需要把这些视图拖到代码中来:

    Also you can use IBOutlet to connect the xib and the code.

@property (strong, nonatomic) IBOutlet UILabel *label;
@property (strong, nonatomic) IBOutlet UIView *box1;
@property (strong, nonatomic) IBOutlet UIView *box2;
@property (strong, nonatomic) IBOutlet UIView *box3;
@property (strong, nonatomic) IBOutlet UIImageView *avatar;
@property (strong, nonatomic) IBOutlet UIImageView *pic;
