// 自定义卡片尺寸 self.stackedLayout.itemSize CGSizeMake(300, 200); // 控制每个卡片显示的部分高度 self.stackedLayout.topReveal 100.0; // 启用高度填充模式 self.stackedLayout.fillHeight YES; // 单个卡片时垂直居中 self.stackedLayout.centerSingleItem YES;关键配置参数说明layoutMargin控制卡片与容器边界的间距itemSize自定义卡片尺寸设置为CGSizeZero时自动计算topReveal每个堆叠卡片显示的高度部分fillHeight当卡片数量不足时是否均匀分布高度centerSingleItem单个卡片是否垂直居中2. 展开布局高级配置TGLExposedLayout提供了展开状态下的布局控制// 设置展开布局的边距 self.exposedLayoutMargin UIEdgeInsetsMake(40.0, 20.0, 20.0, 20.0); // 自定义展开卡片尺寸 self.exposedItemSize CGSizeMake(320, 400); // 控制卡片重叠效果 self.exposedTopOverlap 15.0; self.exposedBottomOverlap 15.0; self.exposedBottomOverlapCount 2; // 设置固定模式 self.exposedPinningMode TGLExposedLayoutPinningModeAll;展开布局模式详解TGLExposedLayoutPinningModeNone卡片被推到展开卡片的上方和下方TGLExposedLayoutPinningModeBelow上方卡片推到展开卡片顶部下方卡片固定到底部TGLExposedLayoutPinningModeAll所有非展开卡片固定到底部✨ 高级动画效果定制1. 手势交互动画配置TGLStackedViewController支持丰富的手势交互动画// 设置移动卡片的缩放因子 self.movingItemScaleFactor 0.90; // 控制移动卡片是否在最上层显示 self.movingItemOnTop YES; // 配置展开卡片的手势关闭阈值 self.collapsePanMinimumThreshold 100.0; self.collapsePanMaximumThreshold 0.0; // 使用卡片高度 self.collapsePinchMinimumThreshold 0.30; // 启用交互式折叠 self.exposedItemsAreCollapsible YES; // 允许点击未展开卡片进行选择 self.unexposedItemsAreSelectable NO;2. 自定义转场动画通过继承TGLStackedViewController你可以实现完全自定义的转场动画// 自定义展开/折叠动画 - (void)setExposedItemIndexPath:(NSIndexPath *)indexPath animated:(BOOL)animated completion:(void (^)(void))completion { // 自定义动画前的准备工作 [self prepareForCustomAnimation]; // 调用父类方法执行默认动画 [super setExposedItemIndexPath:indexPath animated:animated]; // 添加自定义动画效果 if (animated) { [UIView animateWithDuration:0.3 animations:^{ // 自定义动画代码 [self applyCustomAnimationEffects]; } completion:^(BOOL finished) { if (completion) completion(); }]; } else { if (completion) completion(); } } 自定义布局类开发1. 创建自定义堆叠布局继承TGLStackedLayout以实现完全自定义的布局算法// CustomStackedLayout.h interface CustomStackedLayout : TGLStackedLayout property (nonatomic, assign) CGFloat customSpacing; property (nonatomic, assign) BOOL enableParallaxEffect; end // CustomStackedLayout.m implementation CustomStackedLayout - (NSArrayUICollectionViewLayoutAttributes * *)layoutAttributesForElementsInRect:(CGRect)rect { NSArray *attributes [super layoutAttributesForElementsInRect:rect]; // 添加自定义布局逻辑 for (UICollectionViewLayoutAttributes *attribute in attributes) { if (self.enableParallaxEffect) { // 实现视差滚动效果 CGFloat distanceFromCenter fabs(attribute.center.y - self.collectionView.contentOffset.y - CGRectGetHeight(self.collectionView.bounds) / 2); CGFloat scale 1.0 - distanceFromCenter / CGRectGetHeight(self.collectionView.bounds) * 0.3; attribute.transform3D CATransform3DMakeScale(scale, scale, 1.0); } } return attributes; } - (UICollectionViewLayoutAttributes *)layoutAttributesForItemAtIndexPath:(NSIndexPath *)indexPath { UICollectionViewLayoutAttributes *attributes [super layoutAttributesForItemAtIndexPath:indexPath]; // 自定义每个卡片的位置计算 if (self.customSpacing 0) { CGRect frame attributes.frame; frame.origin.y indexPath.item * self.customSpacing; attributes.frame frame; } return attributes; } end2. 创建自定义展开布局继承TGLExposedLayout以实现独特的展开效果// CustomExposedLayout.h interface CustomExposedLayout : TGLExposedLayout property (nonatomic, assign) CGFloat cornerRadius; property (nonatomic, assign) BOOL enableShadowEffect; end // CustomExposedLayout.m implementation CustomExposedLayout - (void)prepareLayout { [super prepareLayout]; // 自定义布局准备工作 if (self.enableShadowEffect) { for (UICollectionViewLayoutAttributes *attributes in [self layoutAttributesForElementsInRect:self.collectionView.bounds]) { attributes.shadowColor [UIColor blackColor].CGColor; attributes.shadowOffset CGSizeMake(0, 3); attributes.shadowOpacity 0.3; attributes.shadowRadius 5.0; } } } - (UICollectionViewLayoutAttributes *)layoutAttributesForItemAtIndexPath:(NSIndexPath *)indexPath { UICollectionViewLayoutAttributes *attributes [super layoutAttributesForItemAtIndexPath:indexPath]; // 添加圆角效果 if (self.cornerRadius 0) { attributes.zIndex indexPath.item; if (available(iOS 13.0, *)) { attributes.backgroundView [[UIView alloc] init]; attributes.backgroundView.layer.cornerRadius self.cornerRadius; attributes.backgroundView.layer.masksToBounds YES; } } return attributes; } end 性能优化技巧1. 内存管理优化// 在视图控制器中优化内存使用 - (void)viewDidLoad { [super viewDidLoad]; // 注册自定义单元格类 [self.collectionView registerClass:[CustomCollectionViewCell class] forCellWithReuseIdentifier:CustomCell]; // 预加载布局属性 [self.collectionView.collectionViewLayout prepareLayout]; // 启用预估尺寸优化 if (available(iOS 10.0, *)) { self.collectionView.prefetchingEnabled YES; } } // 重用单元格优化 - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath { CustomCollectionViewCell *cell [collectionView dequeueReusableCellWithReuseIdentifier:CustomCell forIndexPath:indexPath]; // 轻量级配置 [cell configureWithData:self.dataArray[indexPath.item]]; return cell; }2. 平滑滚动优化// 在TGLStackedViewController子类中 - (void)scrollViewDidScroll:(UIScrollView *)scrollView { [super scrollViewDidScroll:scrollView]; // 优化滚动性能 [self optimizeScrollingPerformance]; } - (void)optimizeScrollingPerformance { // 减少离屏渲染 self.collectionView.layer.shouldRasterize YES; self.collectionView.layer.rasterizationScale [UIScreen mainScreen].scale; // 启用硬件加速 for (UICollectionViewCell *cell in self.collectionView.visibleCells) { cell.layer.drawsAsynchronously YES; } } 手势交互深度定制1. 自定义手势识别器// 添加自定义手势 - (void)setupCustomGestures { // 添加长按手势进行高级操作 UILongPressGestureRecognizer *longPressGesture [[UILongPressGestureRecognizer alloc] initWithTarget:self action:selector(handleLongPress:)]; longPressGesture.minimumPressDuration 0.5; [self.collectionView addGestureRecognizer:longPressGesture]; // 添加双击手势快速切换 UITapGestureRecognizer *doubleTapGesture [[UITapGestureRecognizer alloc] initWithTarget:self action:selector(handleDoubleTap:)]; doubleTapGesture.numberOfTapsRequired 2; [self.collectionView addGestureRecognizer:doubleTapGesture]; } // 处理自定义手势 - (void)handleLongPress:(UILongPressGestureRecognizer *)gesture { if (gesture.state UIGestureRecognizerStateBegan) { CGPoint location [gesture locationInView:self.collectionView]; NSIndexPath *indexPath [self.collectionView indexPathForItemAtPoint:location]; if (indexPath) { // 执行长按操作 [self showContextMenuForItemAtIndexPath:indexPath]; } } }2. 手势冲突解决// 处理手势冲突 - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { // 允许特定手势同时识别 if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]] [otherGestureRecognizer isKindOfClass:[UIScreenEdgePanGestureRecognizer class]]) { return YES; } return NO; } // 优先级控制 - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { // 确保特定手势优先 if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]] [otherGestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]]) { return YES; } return NO; } 实际应用场景1. 卡片式任务管理器利用TGLStackedViewController创建类似Reminders的任务管理应用// TaskManagerViewController.m implementation TaskManagerViewController - (void)viewDidLoad { [super viewDidLoad]; // 配置任务管理器样式 self.stackedLayout.topReveal 80.0; self.stackedLayout.layoutMargin UIEdgeInsetsMake(20, 15, 20, 15); // 设置展开卡片样式 self.exposedItemSize CGSizeMake(self.view.bounds.size.width - 40, 300); self.exposedLayoutMargin UIEdgeInsetsMake(60, 20, 20, 20); // 启用手势交互 self.exposedItemsAreCollapsible YES; self.unexposedItemsAreSelectable YES; } // 自定义单元格配置 - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath { TaskCardCell *cell [collectionView dequeueReusableCellWithReuseIdentifier:TaskCard forIndexPath:indexPath]; Task *task self.tasks[indexPath.item]; [cell configureWithTask:task]; // 根据任务状态设置样式 if (task.isCompleted) { cell.alpha 0.7; cell.transform CGAffineTransformMakeScale(0.95, 0.95); } return cell; } end2. 图片浏览器应用创建具有堆叠效果的图片浏览器// PhotoBrowserViewController.m implementation PhotoBrowserViewController - (void)configureForPhotoBrowser { // 优化图片浏览体验 self.stackedLayout.itemSize CGSizeMake(280, 200); self.stackedLayout.topReveal 60.0; // 设置展开模式为无固定 self.exposedPinningMode TGLExposedLayoutPinningModeNone; self.exposedTopOverlap 20.0; self.exposedBottomOverlap 20.0; self.exposedBottomOverlapCount 3; // 自定义动画参数 self.movingItemScaleFactor 0.85; self.collapsePinchMinimumThreshold 0.4; } // 处理图片加载和缓存 - (void)loadImageForCell:(PhotoCell *)cell atIndexPath:(NSIndexPath *)indexPath { Photo *photo self.photos[indexPath.item]; // 使用异步加载和缓存 [cell.imageView setImageWithURL:photo.url placeholderImage:[UIImage imageNamed:placeholder] completed:^(UIImage *image, NSError *error) { if (image !error) { // 图片加载成功后的处理 [cell setNeedsLayout]; } }]; } end 高级技巧与最佳实践1. 动态布局调整// 响应设备旋转和尺寸变化 - (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(idUIViewControllerTransitionCoordinator)coordinator { [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator]; [coordinator animateAlongsideTransition:^(idUIViewControllerTransitionCoordinatorContext context) { // 动态调整布局参数 [self adjustLayoutForSize:size]; // 强制重新布局 [self.collectionView.collectionViewLayout invalidateLayout]; [self.collectionView reloadData]; } completion:nil]; } - (void)adjustLayoutForSize:(CGSize)size { // 根据屏幕尺寸调整布局 if (size.width size.height) { // 横屏模式 self.stackedLayout.itemSize CGSizeMake(250, 180); self.exposedItemSize CGSizeMake(size.width - 100, size.height - 150); } else { // 竖屏模式 self.stackedLayout.itemSize CGSizeMake(size.width - 40, 200); self.exposedItemSize CGSizeMake(size.width - 40, 300); } }2. 状态保存与恢复// 保存和恢复展开状态 - (void)encodeRestorableStateWithCoder:(NSCoder *)coder { [super encodeRestorableStateWithCoder:coder]; // 保存当前展开的卡片索引 if (self.exposedItemIndexPath) { [coder encodeInteger:self.exposedItemIndexPath.item forKey:exposedItemIndex]; } // 保存滚动位置 [coder encodeCGPoint:self.collectionView.contentOffset forKey:contentOffset]; } - (void)decodeRestorableStateWithCoder:(NSCoder *)coder { [super decodeRestorableStateWithCoder:coder]; // 恢复展开状态 if ([coder containsValueForKey:exposedItemIndex]) { NSInteger index [coder decodeIntegerForKey:exposedItemIndex]; if (index [self.collectionView numberOfItemsInSection:0]) { NSIndexPath *indexPath [NSIndexPath indexPathForItem:index inSection:0]; [self setExposedItemIndexPath:indexPath animated:NO]; } } // 恢复滚动位置 if ([coder containsValueForKey:contentOffset]) { self.collectionView.contentOffset [coder decodeCGPointForKey:contentOffset]; } } 性能监控与调试1. 布局性能分析// 添加布局性能监控 - (void)monitorLayoutPerformance { // 使用CADisplayLink监控帧率 CADisplayLink *displayLink [CADisplayLink displayLinkWithTarget:self selector:selector(updateFrameRate:)]; [displayLink addToRunLoop:[NSRunLoop mainRunLoop] forMode:NSRunLoopCommonModes]; // 监控布局计算时间 CFTimeInterval startTime CACurrentMediaTime(); [self.collectionView.collectionViewLayout prepareLayout]; CFTimeInterval endTime CACurrentMediaTime(); NSLog(布局计算时间: %.3f ms, (endTime - startTime) * 1000); } - (void)updateFrameRate:(CADisplayLink *)link { static CFTimeInterval lastTime 0; static int frameCount 0; CFTimeInterval currentTime link.timestamp; if (lastTime 0) { lastTime currentTime; return; } frameCount; if (currentTime - lastTime 1.0) { CGFloat fps frameCount / (currentTime - lastTime); NSLog(当前帧率: %.1f FPS, fps); frameCount 0; lastTime currentTime; } } 总结TGLStackedViewController为iOS开发者提供了一个强大而灵活的工具用于创建具有专业级动画效果的卡片堆叠界面。通过掌握本文介绍的高级技巧你可以完全自定义布局行为- 通过继承TGLStackedLayout和TGLExposedLayout实现独特的布局效果精细控制动画参数- 调整手势阈值、缩放因子和转场动画优化性能表现- 使用内存管理和滚动优化技术创建丰富的交互体验- 添加自定义手势和状态管理无论是构建任务管理应用、图片浏览器还是任何需要卡片式界面的场景TGLStackedViewController都能帮助你快速实现高质量的用户体验。记住最好的用户体验来自于对细节的关注和不断的优化迭代。开始使用TGLStackedViewController吧让你的应用拥有令人惊艳的卡片堆叠效果【免费下载链接】TGLStackedViewControllerA stacked view layout with gesture-based reordering using a UICollectionView -- inspired by Passbook and Reminders apps.项目地址: https://gitcode.com/gh_mirrors/tg/TGLStackedViewController创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
