触摸tableview后，PopOver中的iOS TableViewController消失 [英] iOS TableViewController in PopOver disappears after touching tableview

问题描述

我正在开发通用的iOS应用，并尝试实现弹出窗口. 我已经尝试过WYPopoverController和FPPopover，但是那两个也有同样的问题.

I am developing universal iOS app and try to achieve popover. I have tried WYPopoverController and FPPopover but those 2 does the same issue.

我有一个简单的UITableViewController，其中有10个单元格，在每个单元格上放置一个静态文本(仅用于测试).

I have simple UITableViewController having 10 cells putting a static text on each cell (just for a test).

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
     return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 10;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath     *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier     forIndexPath:indexPath];

    UILabel *label = (UILabel *) [cell viewWithTag:1];
    [label setText:@"test"];

    return cell;
}

并尝试在弹出窗口中显示.

and try to show this in popover.

应用FPPopover的示例代码为

Sample code to apply FPPopover is

- (IBAction)test:(id)sender {
    PopOverTableViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"PopOverTableViewController"];

    FPPopoverController *popOver = [[FPPopoverController alloc] initWithViewController:vc];

    [popOver presentPopoverFromView:sender];
}

这会在一个按钮上显示10个单元格中的文本，但是一旦我在表格视图中滚动， 文本消失，随后将调用非tableview数据源方法.

This shows text in 10 cells at a button tap but once I scroll inside of tableview, the texts disappear and non of tableview data source methods are called afterwards.

WYPopoverController和FPPopover都发生了，所以我假设我这边出了问题. 但是，我无法弄清楚哪里出了问题.

It happened for both WYPopoverController and FPPopover so I am assuming there is something wrong in my side. However, I could not figure out where I went wrong.

感谢您在此方面的帮助.

I appreciate your help on this.

推荐答案

谢谢你们回答我的问题. 我解决了自己.这是由于在局部变量中有FPPopoverController.我需要将具有强大属性的实例变量放入，否则控制器将由ARC释放.使得弹出框仍然可见，但是弹出框内的表视图内容被忽略了.

Thank you guys for answering my question. I solved myself. It was due to having FPPopoverController as in local variable. I needed to put as instance variable with strong property, otherwise the controller is deallocated by ARC. That made a popover frame is still visible but table view content inside of popover is dismissed.
