首先是一个视图实现表格方法

<UITableViewDelegate,UITableViewDataSource>


{

//数组

UITableView *table;

//    表格元素

NSArray *imgarr,*name;

}

这里是初始化

table = [[UITableView alloc]initWithFrame:self.view.frame style:UITableViewStylePlain];

//    代理

table.delegate = self;

table.dataSource = self;

//    加载

[self.view addSubview:table];

//    数组内容

imgarr = @[@"1",@"2",@"3"];

name = @[@"确认添加",@"删除添加",@"关闭"];

这里是代理方法

//分区行数

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

return imgarr.count;

}

//内容

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@""];

if (!cell) {

cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@""];

}

cell.imageView.image = [UIImage imageNamed:imgarr[indexPath.row]];

cell.textLabel.text = name[indexPath.row];

return cell;

}

//点击行相应事件

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

//    判断第几行

if (indexPath.row == 0) {

//        提示框

UIAlertController*alertController = [UIAlertController alertControllerWithTitle:@"确认添加"message:@"操作以完成" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *action = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil];

[alertController addAction:action];

[self presentViewController:alertController animated:YES completion:nil];

}

//如果等于第二行

else if (indexPath.row == 1){

//        提示框

UIAlertController*alertController = [UIAlertController alertControllerWithTitle:@"删除添加"message:@"操作以完成" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *action = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil];

[alertController addAction:action];

[self presentViewController:alertController animated:YES completion:nil];

}

else if (indexPath.row == 2){

//        提示框

UIAlertController*alertController = [UIAlertController alertControllerWithTitle:@"关闭"message:@"操作以完成" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *action = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil];

[alertController addAction:action];

[self presentViewController:alertController animated:YES completion:nil];

}

}

调用在这里实现

//实现按钮方法

-(void)btnclick{

//初始化内容视图控制器

PopViewController *popview = [[PopViewController alloc]init];

//设置大小

popview.preferredContentSize = CGSizeMake(150, 140);

// 设置弹出效果

popview.modalPresentationStyle = UIModalPresentationPopover;

//初始化一个popover

self.pop = popview.popoverPresentationController;

self.pop.delegate = self;

//设置弹出视图的颜色

self.pop.backgroundColor = [UIColor whiteColor];

//设置popover的来源按钮(以button谁为参照)

self.pop.sourceView = btn;

//设置弹出视图的位置(以button谁为参照)

self.pop.sourceRect = btn.bounds;

//箭头的方向 设置成UIPopoverArrowDirectionAny 会自动转换方向

self.pop.permittedArrowDirections = UIPopoverArrowDirectionUp;

//模态出弹框

[self presentViewController:popview animated:YES completion:nil];

}

- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller{

return UIModalPresentationNone;

}

//点击蒙版是否消失,默认为yes;

-(BOOL)popoverPresentationControllerShouldDismissPopover:(UIPopoverPresentationController *)popoverPresentationController{

return YES;

}

//弹框消失时调用的方法

-(void)popoverPresentationControllerDidDismissPopover:(UIPopoverPresentationController *)popoverPresentationController{

NSLog(@"弹框已经消失");

}
