创建自定义tableview分隔符时出错 [英] error creating custom tableview separator

问题描述

我正在尝试使用自定义分隔符创建一个表视图.我制作了一个自定义单元格，用于保存内容，而另一个单元格仅包含带有分隔符的UIImageView. 问题在于如何访问内容. 我不能使用indexPath.row

I'm trying to create a tableview with custom separator. I made a custom Cell that holds the content, and another that contains only a UIImageView with the separator. The problem is in how content is being accessed. I can not use the indexPath.row

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier: @"CustomCell"];
    if(cell == nil) 
    { 
        cell = [[[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil] objectAtIndex:0];
    }

    SeparatorCell *cellSeparator = (SeparatorCell *) [tableView dequeueReusableCellWithIdentifier: @"SeparatorCell"];
    if(cellSeparator == nil) 
    { 
        cellSeparator = [[[NSBundle mainBundle] loadNibNamed:@"SeparatorCell" owner:self options:nil] objectAtIndex:0];
    }

    if(indexPath.row % 2)
    {
        UIFont * myCustomFont = [UIFont fontWithName:@"Arial Black" size:16];
        [cell.titulo setFont:myCustomFont];
        cell.titulo.textColor = [UIColor colorWithRed:103/255.0f green:169/255.0f blue:0/255.0f alpha:1];

        cell.titulo.text = [Title objectAtIndex:myRow];
        cell.subtitle.text = [Subtitle objectAtIndex:myRow];

        cell.tag = myRow;
        myRow++;
    }
    else [cellSeparator.imagem setImage:[UIImage imageNamed:@"CustomSeparator.png"]];

    if(indexPath.row % 2) return cell;
    else return cellSeparator;
}

myRow

myRow

是全局NSInteger.

is a global NSInteger.

我已经尝试过

if(myRow == Title.count) myRow=0;
        else myRow++;

推荐答案

尝试一下:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // Return the number of rows in the section.
    NSInteger numOfRowsIncludeSeparator = 0;

    if (self.model.count > 0) {
        NSInteger numOfSeperators = self.model.count - 1;
        numOfRowsIncludeSeparator = self.model.count + numOfSeperators;
    }
    return numOfRowsIncludeSeparator;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *ContentCellIdentifier = @"ContentCell";
    static NSString *SeparatorCellIdentifier = @"SeparatorCell";

    UITableViewCell *cell = nil;

    if (indexPath.row % 2 == 0) {
        // this is a content cell
        cell = [tableView dequeueReusableCellWithIdentifier:ContentCellIdentifier];

        if(cell == nil) 
        { 
            cell = [[[NSBundle mainBundle] loadNibNamed:@"ContentCell" owner:self options:nil] objectAtIndex:0];
        }

        // get the model index
        NSInteger indexInModel = indexPath.row / 2;

        // get the model for this row
        NSString *modelObject = [self.model objectAtIndex:indexInModel];

        // Configure the cell...
        cell.textLabel.text = modelObject;
    }
    else {
        // this is a separator cell
        cell = [tableView dequeueReusableCellWithIdentifier:SeparatorCellIdentifier];

        if(cell == nil) 
        { 
            cell = [[[NSBundle mainBundle] loadNibNamed:@"SeparatorCell" owner:self options:nil] objectAtIndex:0];
        }
    }

    return cell;
}  

不要忘记将ContentCell.xib的IB中的Identifier字段设置为"ContentCell"，将SeparatorCell.xib设置为"SeparatorCell".

Don't forget to set the Identifier field in IB of the ContentCell.xib to be "ContentCell" and the SeparatorCell.xib to be "SeparatorCell".
