具體應(yīng)用場(chǎng)景看簡(jiǎn)書首頁(yè)檩奠、微博首頁(yè), 實(shí)現(xiàn)預(yù)覽的效果, 而下面是我做的效果圖
預(yù)覽.png
預(yù)覽
在開始之前
UIViewControllerPreviewingDelegate // 簽訂這個(gè)協(xié)議
Objective-C版本
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cellId"];
// 對(duì)每個(gè)cell指定代理, 大致是這個(gè)意思
[self registerForPreviewingWithDelegate:self sourceView:cell];
//
cell.textLabel.text = self.arrayData[indexPath.row];
return cell;
}
#pragma mark - peek的代理方法桩了，輕按即可觸發(fā)彈出vc
- (UIViewController *)previewingContext:(id <UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location{
//通過(guò)[previewingContext sourceView]拿到對(duì)應(yīng)的cell的數(shù)據(jù)；
NSIndexPath *indexPath = [_tableView indexPathForCell:(UITableViewCell* )[previewingContext sourceView]];
// 用于顯示預(yù)覽的vc
ListViewController *listVc = [[ListViewController alloc] init];
// 演示的是傳入一個(gè)字符串 , 實(shí)際可能是你需要的model
listVc.strText = [self.arrayData objectAtIndex:indexPath.row];
return listVc;
}
#pragma mark - pop的代理方法埠戳，在此處可對(duì)將要進(jìn)入的vc進(jìn)行處理
- (void)previewingContext:(id <UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit
{
}
在 ListViewController 中我用一個(gè)label作為演示的, 您可能還需要添加底部菜單(類似于 收藏 喜歡這樣)
-(NSArray<id<UIPreviewActionItem>> *)previewActionItems
{
UIPreviewAction * action1 = [UIPreviewAction actionWithTitle:@"收藏" style:1 handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
NSLog(@"收藏");
}];
UIPreviewAction * action2 = [UIPreviewAction actionWithTitle:@"喜歡" style:0 handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
NSLog(@"喜歡");
}];
NSArray *items = @[action1,action2];
return items;
}
Swift版本
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
// 指定代理人
if #available(iOS 9.0, *) {
self.registerForPreviewingWithDelegate(self, sourceView: cell)
} else {
// Fallback on earlier versions
}
}
/// MARK: - peek的代理方法, 長(zhǎng)按觸發(fā)彈出預(yù)覽VC
func previewingContext(previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
let preVC = PreviewViewController()
if #available(iOS 9.0, *) {
let indexPath = self.tableView.indexPathForCell((previewingContext.sourceView) as! AlamofieCustomCell)! as NSIndexPath
preVC.preViewModel = self.dataArray[indexPath.row] as! AlamofireVCModel
} else {
// Fallback on earlier versions
}
return preVC
}
/// MARK: - pop的代理方法井誉，在此處可對(duì)將要進(jìn)入的vc進(jìn)行處理
func previewingContext(previewingContext: UIViewControllerPreviewing, commitViewController viewControllerToCommit: UIViewController) {
// code
}
@available(iOS 9.0, *)
override func previewActionItems() -> [UIPreviewActionItem] {
var items = [UIPreviewAction]()
let action1 = UIPreviewAction.init(title: "收藏", style: UIPreviewActionStyle.Default, handler: { (action: UIPreviewAction, previewViewController: UIViewController) in
print("收藏")
})
let action2 = UIPreviewAction.init(title: "喜歡", style: UIPreviewActionStyle.Default, handler: { (action: UIPreviewAction, previewViewController: UIViewController) in
print("喜歡")
})
items.append(action1)
items.append(action2)
return items;
}
