[英]How to do action using Button in UITableViewCell?
我有一个在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,该按钮显示在我在TableViewController中创建的UITableView内的单元格中。 我可以将onoffBtn按下我的单元格,但它无法执行操作。 我该如何做才能使我的按钮起作用?
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;
}
还有其他问题,我应该在哪里写流程? 在我的TableViewController.m或CustomCell.m中? 如果您不介意,请向我提供代码和说明,此处是新内容,并且仍在学习中。 我想了解您编写的每一行代码。 谢谢。
更新:
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:
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?
这是您如何在细胞中添加按钮的动作
- (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
}
}
