我有一个我在CustomCell中创建的按钮。
- (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,按钮显示在我在TableViewController中创建的UITableView中的单元格中。我可以在我的单元格内按下onoffBtn,但它无法做出动作。我怎么这样做,我的按钮可以采取行动?
这是我的TableViewController.m
中的cellForRowAtIndexPath- (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;
}
对于其他问题,我应该在哪里写do process?在我的TableViewController.m或我的CustomCell.m中?如果你不介意,请提供代码和解释,我在这里新的,仍在学习。我想了解你编写的每一行代码。谢谢。

到目前为止,这是我在TableViewController.m中的cellForRowAtIndexPath:
- (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;
}
这是日志说的:
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?
答案 0 :(得分:1)
这就是你如何在一个细胞中加入按钮
- (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
}
}
