ios - UITableView 中的复选框

Question

在 UITableView 中，我想放置选中取消选中按钮，当我单击第一行 [indexpath.row=0] 时，其余行将取消选中，当单击 indexpath.row>0 时，row=0 取消选中。我必须反之亦然，

最初我拿了一个数组，其中所有对象都未选中，当检查它时索引将替换对象检查，

for(int i=0; i<[carwasharray count]; i++)
{
    [arrayCheckUnchek addObject:@"Uncheck"];
}
/cell row at indexpath my code is
cell.textLabel.text = [carwasharray objectAtIndex:indexPath.row];
if (indexPath.row==0) {
     button1 = [UIButton buttonWithType:UIButtonTypeCustom];
     [button1 setImage:[UIImage imageNamed:@"uncheck_icon.png"] forState:UIControlStateNormal];
    [button1 addTarget:self action:@selector(buttonClic:) forControlEvents:UIControlEventTouchUpInside];
    button1.tag=1;
    [button1 setFrame:CGRectMake(150.0, 7.0, 30.0, 30.0)];
    [cell.contentView addSubview:button1];
}
else{
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(150.0, 7.0, 30.0, 30.0)];
    button.tag=2;
if([[arrayCheckUnchek objectAtIndex:indexPath.row] isEqualToString:@"Uncheck"])
    [button setImage:[UIImage imageNamed:@"uncheck_icon.png"] forState:UIControlStateNormal];
else
    [button setImage:[UIImage imageNamed:@"check_icon"] forState:UIControlStateNormal];

[button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button];
}
return cell;

-(void)buttonClic:(id)sender
{
//Getting the indexPath of cell of clicked button
CGPoint touchPoint = [sender convertPoint:CGPointZero toView:carwashtable];
NSIndexPath *indexPath = [carwashtable indexPathForRowAtPoint:touchPoint];
UIButton *button = (UIButton *)sender;
if (button1.tag==1)
{
    if([[arrayCheckUnchek objectAtIndex:indexPath.row] isEqualToString:@"Uncheck"])
    {

     //[button1 setImage:[UIImage imageNamed:@"check_icon.png"] forState:UIControlStateNormal];
        //[button setImage:[UIImage imageNamed:@"uncheck.png"] forState:UIControlStateNormal];
       // [arrayCheckUnchek replaceObjectAtIndex:indexPath.row withObject:@"Check"];
        button.tag=3;
        [self buttonClicked:button];
    }
    else
    {
        //[button1 setImage:[UIImage imageNamed:@"check_icon.png"] forState:UIControlStateNormal];
        [arrayCheckUnchek replaceObjectAtIndex:indexPath.row withObject:@"Check"];

        button.tag=3;
        [self buttonClicked:button];

    }
}
else if(button1.tag==0){
    [button1 setImage:[UIImage imageNamed:@"uncheck_icon.png"] forState:UIControlStateNormal];

}

-(void)buttonClicked:(id)sender
{ 
//Getting the indexPath of cell of clicked button
 CGPoint touchPoint = [sender convertPoint:CGPointZero toView:carwashtable];
NSIndexPath *indexPath = [carwashtable indexPathForRowAtPoint:touchPoint];
// No need to use tag sender will keep the reference of clicked button
UIButton *button = (UIButton *)sender;
if (button.tag==2) {
    if([[arrayCheckUnchek objectAtIndex:indexPath.row] isEqualToString:@"Uncheck"])
    {      
        [button setImage:[UIImage imageNamed:@"check_icon.png"] forState:UIControlStateNormal];
        [button1 setImage:[UIImage imageNamed:@"uncheck_icon.png"] forState:UIControlStateNormal];
        [arrayCheckUnchek replaceObjectAtIndex:indexPath.row withObject:@"Check"];

        button1.tag=1;
    }
    else
    {
        [button setImage:[UIImage imageNamed:@"uncheck_icon.png"] forState:UIControlStateNormal];
        [arrayCheckUnchek replaceObjectAtIndex:indexPath.row withObject:@"Uncheck"];

    }
}
else
{
    if ([[arrayCheckUnchek objectAtIndex:indexPath.row] isEqualToString:@"Check"]) {
        [button setImage:[UIImage imageNamed:@"uncheck_icon.png"] forState:UIControlStateNormal];


    }
    [button1 setImage:[UIImage imageNamed:@"check_icon.png"] forState:UIControlStateNormal];

}

现在它只在我点击 row=1 时工作 1st 次，row=0 将取消选中，直到这个 ok，但是当我重新选中 row=0 时它也会检查..

提前致谢

UITableView 仅显示您想要的 UITableViewCell。

我建议创建一个原型(prototype)单元格来保存您的文本和“CheckBox”

这是一个页面，展示了创建自定义 UITableViewCell 对象的几种不同方法。

了解如何完成任务与完成任务本身一样重要。
