UITableView 一次只勾选一行

问题描述

使用此代码，我可以检查表中的多行.

With this code, I can check multiple rows in a table.

但我想要的是一次只检查一行.这是我的代码:

But what I want is to only have one row checked at a time. Here's my code:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    
    UITableViewCell *theCell = [tableView cellForRowAtIndexPath:indexPath];
    
    if (theCell.accessoryType == UITableViewCellAccessoryNone) {
        theCell.accessoryType = UITableViewCellAccessoryCheckmark;
    } else if (theCell.accessoryType == UITableViewCellAccessoryCheckmark) {
        theCell.accessoryType = UITableViewCellAccessoryNone;
    }
}

如果用户选择了不同的行，那么我希望旧行简单地自动取消选中.不知道该怎么做.

If a user selects a different row, then I want the old row to simply automatically uncheck. Don't know how to do that.

推荐答案

最好的方法是在cellForRowAtIndexPath中设置附件类型.

The best way is to set the accessory type in cellForRowAtIndexPath.

使用didSelectRowAtIndexPath只记录应该选择哪条路径，然后调用reloadData.

Use didSelectRowAtIndexPath to only record which path should be selected and then call reloadData.
