如何在UITableview中检查UIButtons的条件 [英] how to check the condition for UIButtons in UITableview

问题描述

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.同样，另外两个按钮.

I am having three button image in table view, I want to check the conditions between them. when I click the button 1 means background image change to blue colour. at the same time I click the button 1 it will move to normal state white colour. Same for another two buttons.

- (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可以在两种情况下都可以选择.

My condition is: when button 1 is clicked means button 3 should not change. when button 3 is clicked means button 1 should not change.button 2 can select in both the condition.

- (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];
}
}

任何人都可以帮助我进行编码.

can any one help me in coding.

推荐答案

首先，您可以为每个按钮的样式设置不同的标签

First of all you can set different tag for each button's like

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

然后您可以像这样编写 radiobtn 操作..

And then after you can write your radiobtn Action like this way..

-(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];
  } 
}
