ios - 如何在UITableview中检查UIButtons的条件

我在表格视图中有三个按钮图像，我想检查它们之间的条件。当我单击按钮1时，表示背景图像变为蓝色。同时单击按钮1，它将变为正常状态的白色。其他两个按钮相同。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath![button3 condition][3]
{
static NSString *cellIdentifier = @"HistoryCell";
CustomizedCellView *cell = (CustomizedCellView *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[CustomizedCellView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}

UIButton *button1;
 button1 = [UIButton buttonWithType:UIButtonTypeCustom];
button1.frame = CGRectMake(80, 27, 36, 36);
[button1 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"l"ofType:@"png"]] forState:UIControlStateNormal];
button1.tag = 1;
[button1 addTarget:self action:@selector(radiobtn:) forControlEvents:UIControlEventTouchUpInside];
 [button1 setSelected:true];
[cell.contentView addSubview:button1];

 UIButton *button2;
button2 = [UIButton buttonWithType:UIButtonTypeCustom];
button2.frame = CGRectMake(160, 27, 36, 36);
[button2 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"e"ofType:@"png"]] forState:UIControlStateNormal];
   button2.tag = 1;
[button2 addTarget:self action:@selector(radiobtn:) forControlEvents:UIControlEventTouchUpInside];
[button2 setSelected:true];
[cell.contentView addSubview:button2];

UIButton *button3;
  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 = 1;
[button3 addTarget:self action:@selector(radiobtn:) forControlEvents:UIControlEventTouchUpInside];
[button3 setSelected:true];
[cell.contentView addSubview:button3];

return cell;
}

我的条件是：单击按钮1时，按钮3不应更改。当单击按钮3时，意味着按钮1不应更改。按钮2可以在两种情况下选择。

- (void)radiobtn:(UIButton *)button
{
if(button.tag == 1)
{
[button setImage:[UIImage imageNamed:@"lblue.png"] forState:UIControlStateSelected];
}
 if(button.tag == 2)
{


 [button setImage:[UIImage imageNamed:@"eblue.png"] forState:UIControlStateSelected];
}
if(button.tag == 3)
{
[button setImage:[UIImage imageNamed:@"vblue.png"] forState:UIControlStateSelected];
}
}

谁能帮我编码。

最佳答案

首先，您可以为每个按钮的样式设置不同的标签

 button.tag == 1,
 button.tag == 2,
 button.tag == 3

然后，您可以像这样编写radiobtn操作。

-(IBAction) radiobtn:(id)sender
{
  UIButton *yourBtn = (UIButton *)[self.view viewWithTag:[sender tag]];
  if(yourBtn.tag == 1) {
    [yourBtn setImage:[UIImage imageNamed:@"lblue.png"] forState:UIControlStateSelected];
}
else if(yourBtn.tag == 2){
    [yourBtn setImage:[UIImage imageNamed:@"eblue.png"] forState:UIControlStateSelected];
}
else{
    [yourBtn setImage:[UIImage imageNamed:@"vblue.png"] forState:UIControlStateSelected];
  }
}
