ios – popover中的表视图不滚动

我有下面的代码来显示带有tableview的popover,它完美地运行.

tableview显示13个数字,我可以滚动并看到相同的但是当我在模拟器上发布鼠标触摸时它会回到顶部.

它不会停留在显示它的行,但会将我带回第1到第10行.

滚动后如何使其保持在位置.或者以下代码中的任何修复.

提前致谢.

- (IBACtion)btn:(id)sender {

    if([popoverController isPopoverVisible])
    {
        [popoverController dismissPopoverAnimated:YES];
        return;
    }
    //build our custom popover view
    UIViewController* popoverContent = [[UIViewController alloc]init];
    UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0,320,680)];
    popoverView.BACkgroundColor = [UIColor blackColor];

    @R_696_10793@ers = [[NSMutableArray alloc] initWithObjects:@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"11",@"12",@"13",nil];


    UITableView *tblViewMenu = [[UITableView alloc]initWithFrame:CGRectMake(0,680)];
    tblViewMenu.delegate = self;
    tblViewMenu.datasource = self;
    tblViewMenu.rowHeight = 32;

    [popoverView addSubview:tblViewMenu];
    popoverContent.view = popoverView;
    popoverContent.contentSizeForViewInPopover = CGSizeMake(320,320);
    popoverController = [[UIPopoverController alloc]
                              initWithContentViewController:popoverContent];

    [popoverController  presentPopoverFromRect:self.btn.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}




- (NSInteger)@R_696_10793@erOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return 1;
}


- (NSInteger)tableView:(UITableView *)tableView @R_696_10793@erOfRowsInSection:(NSInteger)section {
    // Return the number of rows in the section.
    return [@R_696_10793@ers count];
}


// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowATindexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reusEIDentifier:CellIdentifier] ;
    }

    // Configure the cell...
    NSString *color = [@R_696_10793@ers objectATindex:indexPath.row];
    cell.textLabel.text = color;

    return cell;
}

#pragma mark -
#pragma mark Table view delegate

- (void)tableView:(UITableView *)tableView didSELEctRowATindexPath:(NSIndexPath *)indexPath {
        NSString *@R_696_10793@er = [@R_696_10793@ers objectATindex:indexPath.row];

    NSLog(@"%@",@R_696_10793@er);

    [popoverController dismissPopoverAnimated:YES];

    }

我猜我需要更改以下值：

UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0,680)];


    UITableView *tblViewMenu = [[UITableView alloc]initWithFrame:CGRectMake(0,680)]];

如果我使用

UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0,320)];

然后

UITableView *tblViewMenu = [[UITableView alloc]initWithFrame:CGRectMake(0,320)]];

但是,当我向下滚动时,它会一直到达顶行.它不会停留在滚动到的同一行中.

CGSize contentSize = CGSizeMake(320,320);

UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0,contentSize.width,contentSize.height)];
popoverView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);

UITableView *tblViewMenu = [[UITableView alloc]initWithFrame:popoverView.bounds];
tblViewMenu.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);

popoverContent.contentSizeForViewInPopover = contentSize;
