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.
pod 'KYParallaxView', '~> 1.0.2'
Two situations to use this framework:
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!
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:@"第%ld页",(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];
}
How to customize the vertical scroll view's content?
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;
