在UITableView中显示多个自定义单元格? [英] Display multiple custom cells in a UITableView?

问题描述

我正在SnowLeopard上使用Xcode 4.2，而我的项目正在使用情节提要.我正在尝试使用2种不同的自定义单元格类型sessionCell和infoCell来实现UITableView.我可以使这两种类型出现在同一列表中，但是现在我有一个新问题? sessionCell仅显示一次，然后显示infoCells的X数-正如我想要的一样-除了第一个infoCell总是被sessionCell覆盖！

I am using Xcode 4.2 on SnowLeopard, and my project is using storyboards. I am trying to implement a UITableView with 2 different custom cell types, sessionCelland infoCell. I can get the 2 types to appear within the same list, but now I have a new problem?! The sessionCell is displayed once, and then X number of infoCells are displayed after it - just as I wanted - except that the first infoCell is always overwritten by the sessionCell!

- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return [self.people count];
}

//inside cellForRowAtIndexPath
    if(indexPath.row == 0) {
cell = [tableView dequeueReusableCellWithIdentifier:@"sessionCell"];
} else {
cell = [tableView dequeueReusableCellWithIdentifier:@"infoCell"];
}
...
return cell;

我试图说return array count + 1，甚至是硬编码的return 7(符合我的示例)，但是两者都不正确！

I've tried to say return array count + 1, or even hardcoded return 7 (it fits my example) but both are incorrect!

myObject *person = [self.people objectAtIndex:indexPath.row];

还是我的问题出在上述那行?我什至尝试过indexPath.row+1 ...

Or does my problem lie in the above line? I've even tried indexPath.row+1...

任何帮助将不胜感激！

推荐答案

如果我正确理解了您的问题，则第一个infoCell(第二个UITableView行)应该显示第一人称对象的数据，对吗?

If I understand your question correctly, the first infoCell (second UITableView row) should display the first person object's data, right?

那么看来您想要:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *sessionCellID = @"sessionID";
    static NSString *infoCellID = @"infoID";

    if( indexPath.row == 0 ) {
        SessionCellClass *cell = nil;
        cell = (SessionCellClass *)[tableView dequeueReusableCellWithIdentifier:sessionCellID];
        if( !cell ) {
            //  do something to create a new instance of cell
            //  either alloc/initWithStyle or load via UINib
        }
        //  populate the cell with session model
        return cell;
    }
    else {
        InfoCellClass *cell = nil;
        cell = (InfoCellClass *)[tableView dequeueReusableCellWithIdentifier:infoCellID];
        if( !cell ) {
            //  do something to create a new instance of info cell
            //  either alloc/initWithStyle or load via UINib
            // ...

            //  get the model object:
            myObject *person = [[self people] objectAtIndex:indexPath.row - 1];

            //  populate the cell with that model object
            //  ...
            return cell;
        }
    }

，您需要返回[[self people] count] + 1作为行数:

and you need to return [[self people] count] + 1 for the row count:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [[self people] count] + 1;
}

以便第n行显示第(n-1)个数据.

so that the n'th row shows the (n-1)th data.
