Question

在UITableViewCell中，不同的单元格上有不同的按钮，当我单击单元格的按钮时，对所有单元格的按钮执行相同的操作，但是当我按下特定单元格的按钮时，我想要的是那个单元应该工作，我知道我需要将它们放在数组中，但是如何？

当我点击按钮时，一个值正在增加，它应该显示在同一个单元格的标签上。

这是代码： -

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    SHEDLIST *info1 = [shed_list objectAtIndex:indexPath.row];
    cell.textLabel.text=info1.SHED_Name;
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

    IDlbl = [[UILabel alloc] initWithFrame:CGRectMake(100, 0, 50, 50)];
    IDlbl.text = info1.SHED_ID;
    IDlbl.textAlignment = NSTextAlignmentCenter;
    [cell addSubview:IDlbl];

    tickbtn = [UIButton buttonWithType:UIButtonTypeCustom];
    [tickbtn setBackgroundImage:[UIImage imageNamed:@"tick.png"]forState:UIControlStateNormal];
    [tickbtn addTarget:self action:@selector(addsheddata) forControlEvents:UIControlEventTouchUpInside];
tickbtn.frame = CGRectMake(170, 5, 30, 30);
    [cell addSubview:tickbtn];

    return cell;
}

-(void) addsheddata:(UIEvent *)event
{
   // here i am performing my action which i want.
}

Answer 1

首先为您的按钮分配标签。

[tickbtn setTag:indexPath.row];
[tickbtn addTarget:self action:@selector(addsheddata:) forControlEvents:UIControlEventTouchUpInside];
tickbtn.frame = CGRectMake(170, 5, 30, 30);
[cell addSubview:tickbtn];

通过此更正您的方法实现。

-(IBAction) addsheddata:(UIControl *)sender
{
        // here i am performing my action which i want.
        UIButton *button = (UIButton*)sender;
        NSIndexPath *myIP = [NSIndexPath indexPathForRow:sender.tag inSection:0];

        //Type cast cell
        UITableViewCell *cell = (UITableViewCell*)[mytblView cellForRowAtIndexPath:myIP];

        UILabel *lbl = cell.lbl;
        lbl.text = @"Your text";
}

Answer 2

将这样的目标添加到按钮

[tickbtn addTarget:self action:@selector(addsheddata:event:) forControlEvents:UIControlEventTouchUpInside];

方法应该是这样的：

 - (void) addsheddata:(id)sender event:(id)event {

        NSSet *touches = [event allTouches];
        UITouch *touch = [touches anyObject];
        CGPoint currentTouchPosition = [touch locationInView:chatContent];
        NSIndexPath *indexPath = [YOUR_TABLE_OBJ indexPathForRowAtPoint: currentTouchPosition];
        UITableViewCell *cell = [YOUR_TABLE_OBJ cellForRowAtIndexPath:indexPath];

}

Answer 3

cellForRowAtIndexPath

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

tickbtn.tag =500+indexPath.row;
//Initialise your  UILabel *lbl and define
lbl.tag = 200+indexPath.row;
lbl.text = // Add Text 
// Add the Uilabel to the tableView
}

处理标签的行动

 -(IBAction) addsheddata:(UIButton *)sender{
     NSIndexPath *indexPath = [NSIndexPath indexPathForRow:sender.tag-500 inSection:0];

     UILabel *lbl = (UILabel *)[self.view viewWithTag:indexPath.Row+200];
NSLog (@"%@", lbl.text);
    // Do further as per your Requirement
    }

Answer 4

tickbtn = [UIButton buttonWithType：UIButtonTypeCustom]; [tickbtn setBackgroundImage：[UIImage imageNamed：@“tick.png”] forState：UIControlStateNormal]; [tickbtn addTarget：self action：@selector（addsheddata）forControlEvents：UIControlEventTouchUpInside]; tickbtn.frame = CGRectMake（170,5,30,30）;

[cell addSubview：tickbtn];

NSString * str = [urarray objectAtIndex：indexPath.row];

[tickbtn setTag：[str intValue]];

- （void）addsheddata：（UIEvent *）event

{

UITableViewCell * clickedCell =（UITableViewCell *）[发送者超级视图];

NSIndexPath *clickedButtonPath = [urtableview indexPathForCell:clickedCell];

}
