UIButton 条件适用于单个索引路径行

Question

我正在创建一个足球比赛应用程序，我在 UITableviewcell 中有两个按钮，我正在检查其条件，我的条件适用于整个 table 视图。我的问题是：我的条件应该适用于 table.see 我在那个 L 按钮 select 中的图像的每一行意味着 V 按钮不应该改变它在第 0 个索引路径中的工作，但是当我 select V 按钮没有改变，我的条件应该适用于每个索引路径行。

  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = @"HistoryCell";
CustomizedCellView *cell = (CustomizedCellView *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
    cell = [[CustomizedCellView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
} 
button1 = [UIButton buttonWithType:UIButtonTypeCustom];
button1.frame = CGRectMake(80, 27, 36, 36);
[button1 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"l"ofType:@"png"]] forState:UIControlStateNormal];
[button1 addTarget:self action:@selector(radiobtn2:) forControlEvents:UIControlEventTouchUpInside];

  button1.tag = 56;
[cell.contentView addSubview:button1];

button3 = [UIButton buttonWithType:UIButtonTypeCustom];
button3.frame = CGRectMake(240, 27, 36, 36);
[button3 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"v"ofType:@"png"]] forState:UIControlStateNormal];
button3.tag = 57;
[button3 addTarget:self action:@selector(radiobtn2:) forControlEvents:UIControlEventTouchUpInside];
 [cell.contentView addSubview:button3];
}
- (void)radiobtn2:(UIButton *)button
{


if (button.tag == 56)
        {

            if ([button isSelected]) {
                [button setImage:[UIImage imageNamed:@"l.png"]
                        forState:UIControlStateNormal];
               NSLog(@" select");
                [button setSelected:NO];
            } else {
                [button setImage:[UIImage imageNamed:@"lblue.png"]
             forState:UIControlStateSelected];
               NSLog(@"not select");
             [button setSelected:YES];
            }
           }else
        {
        }


 if (button.tag == 57)
                {
                    if ([button isSelected]) {
                        [button setImage:[UIImage imageNamed:@"v.png"]
                                forState:UIControlStateNormal];
                  NSLog(@"select");
                    [button setSelected:NO];
                } else {
                    [button setImage:[UIImage imageNamed:@"vblue.png"]
                            forState:UIControlStateSelected];
                    NSLog(@"not select");
                    [button setSelected:YES];
                }
            } else
            {
                NSLog(@"button3 == 1");
            }

。请帮助我，我应该听到什么，我很挣扎，请任何人帮助我编码。 我需要这样的条件

您不应为所有行设置相同的按钮标签。为单个按钮设置 button.tag = 1000+indexPath.row，为 V 按钮设置 2000+indexPath.row（以便将它们分开）。因此，当操作被触发时，您知道它属于哪一行，并且只有那一行才会被设置为选中。

添加了一些更改，请查看

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

   static NSString *cellIdentifier = @"HistoryCell";
   CustomizedCellView *cell = (CustomizedCellView *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
   if (cell == nil) {
      cell = [[CustomizedCellView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
      UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];
      button1.frame = CGRectMake(80, 27, 36, 36);
      [button1 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"l"ofType:@"png"]] forState:UIControlStateNormal];
      [button1 setImage:[UIImage imageNamed:@"lblue.png"]
             forState:UIControlStateSelected];
      [button1 addTarget:self action:@selector(radiobtn2:) forControlEvents:UIControlEventTouchUpInside];

     button1.tag=1; 
     [cell.contentView addSubview:button1];

      UIButton *button3 = [UIButton buttonWithType:UIButtonTypeCustom];
      button3.frame = CGRectMake(240, 27, 36, 36);
      [button3 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"v"ofType:@"png"]] forState:UIControlStateNormal];
      [button3 setImage:[UIImage imageNamed:@"vblue.png"]
                            forState:UIControlStateSelected];

      [button3 addTarget:self action:@selector(radiobtn2:) forControlEvents:UIControlEventTouchUpInside];
 [cell.contentView addSubview:button3];
  button3.tag=2;
} 



- (void)radiobtn2:(UIButton *)sender
{

    UITableViewCell *cell=(UITableViewCell *)sender.superview;
    sender.selected=YES;

   if(sender.tag==1){
      UIButton *otherButton=(UIButton *)[cell viewWithTag:2];
      otherButton.selected=NO;
   }else if(sender.tag==2){
      UIButton *otherButton=(UIButton *)[cell viewWithTag:1];
      otherButton.selected=NO;
   }
}

这应该适合您。但是你应该为这样的设计使用自定义单元格，并使用数据来切换状态..

干杯。

 I think your problem is with button tag. from your current code every 
buttons will get same tag.. 
do this
declare a variable glabally,  NSIndexPath *butIndexPath;
in cellForRow method ,after cell==nil method
put this code
butIndexPath.row=2*indexpath.row;
then use
button1.tag=butIndexPath.row;
button3.tag=butIndexPath.row.+1;


update button action method with below code

 change button.tag == 56 into  button.tag == butIndexPath.row
and  button.tag == 57 into   button.tag == butIndexPath.row+1

您想要在 table 中逐个选择按钮图像（第一行 "L" 看起来已选中，第二行 "V" 看起来已选中，第三行 "L"，第四行"V", 等..)

然后您想获取特定行的特定按钮的状态。我猜对了吗？

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
 {

       static NSString *cellIdentifier = @"HistoryCell";
       CustomizedCellView *cell = (CustomizedCellView *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
       if (cell == nil) {
          cell = [[CustomizedCellView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
          UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];
          button1.frame = CGRectMake(80, 27, 36, 36);
          [button1 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"l"ofType:@"png"]] forState:UIControlStateNormal];
          [button1 setImage:[UIImage imageNamed:@"lblue.png"]
                 forState:UIControlStateSelected];
          [button1 addTarget:self action:@selector(radiobtn2:) forControlEvents:UIControlEventTouchUpInside];

         button1.tag=1; 
         [cell.contentView addSubview:button1];

          UIButton *button3 = [UIButton buttonWithType:UIButtonTypeCustom];
          button3.frame = CGRectMake(240, 27, 36, 36);
          [button3 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"v"ofType:@"png"]] forState:UIControlStateNormal];
          [button3 setImage:[UIImage imageNamed:@"vblue.png"]
                                forState:UIControlStateSelected];

          [button3 addTarget:self action:@selector(radiobtn2:) forControlEvents:UIControlEventTouchUpInside];
     [cell.contentView addSubview:button3];
      button3.tag=2;
    } 

    if ((indexPath.row % 2) == 0) {
        // Make left button selected by default by using setSelected property
    }
    else
    {
        // Make right button selected by default by using setSelected property
    }

}
    So now when ever you do any action you will get appropriated state

UIButton 条件适用于单个索引路径行
