如何在UITableViewCell中使用按钮进行操作？

Question

我有我在我的CustomCell创建一个按钮。

- (IBAction)onoffBtn:(id)sender 
{ 
    UIButton *button = (UIButton *)sender; 
    button.selected = !button.selected; 
    if (button.selected) 
    { 
     // Do action 1 
    } 
    else 
    { 
     // Do action 2 
    } 
} 

当我运行它时，按钮显示在我创建TableViewController UITableView的单元格中。我可以在我的牢房内按下onoffBtn，但它不能采取行动。我该如何做，以便我的按钮可以执行操作？

这是我的我的TableViewController.m

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:[CustomCell reuseIdentifier]]; 
    if (cell == nil) 
    { 
     [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; 
     cell = _customCell; 
     _customCell = nil; 
    } 
    // Show my cell 
    return cell; 
} 

和其它问题内的cellForRowAtIndexPath，在那里我应该写在做的过程吗？在我的TableViewController.m或我的CustomCell.m？如果你不介意，请给我提供代码和解释，即时通讯新的在这里，仍然在学习。我想了解你编写的每一行代码。谢谢。

更新：

这是我的cellForRowAtIndexPath里面TableViewController.m至今：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:[CustomCell reuseIdentifier]]; 
    if (cell == nil) 
    { 
     [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; 
     cell = _customCell; 
     _customCell = nil; 
    } 
    button.tag = indexPath.row; 
    cell.titleLabel.text = [titleArray objectAtIndex:indexPath.row]; 
    cell.timerLabel.text = [timeArray objectAtIndex:indexPath.row]; 
    time = [[secondArray objectAtIndex:indexPath.row] integerValue]; 
    NSLog(@"Title %@, time %@, second %@, time %i, tag %d", titleArray, timeArray, secondArray, time, button.tag); 
    return cell; 
} 

，这是日志说：

2012-08-04 17:38:36.257 Table[1269:f803] Title (
    "Test 1", 
    "Test 2" 
), time (
    "10 secs", 
    "5 secs" 
), second (
    10, 
    5 
), time 10, tag 0 // tag 0 for cell 1 
2012-08-04 17:38:36.261 Table[1269:f803] Title (
    "Test 1", 
    "Test 2" 
), time (
    "10 secs", 
    "5 secs" 
), second (
    10, 
    5 
), time 5, tag 0 // tag should be 1 for cell 2 but it said 0. How to fix it?

这是你如何添加按钮与动作在单元格中

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

// ADDING A BUTTON WITH TARGET 
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundRect]; 
btn.frame = CGRectMake(0, 0, 50, 50); 
btn.showsTouchWhenHighlighted = YES; 
btn.tag = indexPath.row; 
[btn addTarget:self action:@selector(onoffBtn:) forControlEvents:UIControlEventTouchUpInside]; 

[cell.contentView addSubview:btn]; 

return cell; 
} 


- (IBAction)onoffBtn:(id)sender 
{ 
UIButton *button = (UIButton *)sender; 
button.selected = !button.selected; 
if (button.selected) 
{ 
    // Do action 1 
} 
else 
{ 
    // Do action 2 
} 
}
