ラベルとボタンを使用してカスタム tableView を作成しました。セルのボタンをクリックすると、そのセルのラベル テキストのみを変更したい。私の問題は、ボタンをクリックすると、他のセルの対応するラベルも変更されることです。これが私のコードです
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier=@"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier];
if (cell == nil) { cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier: CellIdentifier] autorelease];
UILabel *labelOne = [[UILabel alloc]initWithFrame:CGRectMake(70, 10, 100, 20)];
labelOne.tag = 100;
labelOne.backgroundColor=[UIColor clearColor];
labelOne.font=[UIFont systemFontOfSize:14];
[cell.contentView addSubview:labelOne];
[labelOne release];
UIButton *minusbutton=[[UIButton alloc]initWithFrame:CGRectMake(152, 5, 15, 20)];
minusbutton.backgroundColor=[UIColor clearColor];
[minusbutton addTarget:self action:@selector(DecreaseTickets:) forControlEvents:UIControlEventTouchUpInside];
[minusbutton setTitle:@"-" forState:UIControlStateNormal];
[minusbutton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[minusbutton setBackgroundImage:[UIImage imageNamed:@"button-green1.png"] forState:UIControlStateNormal];
[cell.contentView addSubview:minusbutton];
[minusbutton release];
UILabel *quantity = [[UILabel alloc]initWithFrame:CGRectMake(170, 5, 20, 20)];
quantity.tag = 103;
quantity.backgroundColor=[UIColor clearColor];
quantity.font=[UIFont systemFontOfSize:12];
[cell.contentView addSubview:quantity];
[quantity release];
UIButton *addbutton=[[UIButton alloc]initWithFrame:CGRectMake(192, 5, 15, 20)];
addbutton.backgroundColor=[UIColor clearColor];
[addbutton addTarget:self action:@selector(IncreaseTickets:) forControlEvents:UIControlEventTouchUpInside];
[addbutton setTitle:@"+" forState:UIControlStateNormal];
[addbutton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[addbutton setBackgroundImage:[UIImage imageNamed:@"button-green1.png"] forState:UIControlStateNormal];
[cell.contentView addSubview:addbutton];
[addbutton release];
UILabel *labelTwo = [[UILabel alloc]initWithFrame:CGRectMake(260, 10, 140, 20)];
labelTwo.tag = 101;
labelTwo.backgroundColor=[UIColor clearColor];
labelTwo.font=[UIFont systemFontOfSize:14];
labelTwo.textColor=[UIColor colorWithRed:0.25098 green:0.447059 blue:0.07451 alpha:1];
[cell.contentView addSubview:labelTwo];
[labelTwo release];
UILabel *label3 = [[UILabel alloc]initWithFrame:CGRectMake(70, 30, 230, 30)];
label3.tag = 102;
label3.backgroundColor=[UIColor clearColor];
label3.numberOfLines=2;
label3.font=[UIFont systemFontOfSize:12];
[cell.contentView addSubview:label3];
[label3 release];
}
UILabel *labelOne = (UILabel *) [cell.contentView viewWithTag:100];
NSString *ss2=[[NSString alloc]initWithFormat:@"%@",[[eventTicketListArray objectAtIndex:indexPath.row ]tit] ];
labelOne.text = ss2;
UILabel *labelTwo = (UILabel *) [cell.contentView viewWithTag:101];
labelTwo.text = [[NSString alloc]initWithFormat:@"%@",[[eventTicketListArray objectAtIndex:indexPath.row ]price] ];
UILabel *label3 = (UILabel *) [cell.contentView viewWithTag:102];
label3.text=[[NSString alloc]initWithFormat:@"%@",[[eventTicketListArray objectAtIndex:indexPath.row ]desc ] ];
UILabel *label4 = (UILabel *) [cell.contentView viewWithTag:103];
label4.text=[[NSString alloc]initWithFormat:@"%d",qty];
}
return cell;
}
Initially qty=0
addbutton をクリックすると、そのセルの数量が増えるようになりました。ここに私のボタンクリックイベントがあります
-(void)IncreaseTickets:(id)sender{
NSIndexPath *indexPath =[ticketTable indexPathForCell:(UITableViewCell *)[[sender superview] superview]];
//NSUInteger row = indexPath.row;
UITableViewCell *currentCell = (UITableViewCell *)[[sender superview] superview] ;
UILabel *label4 = (UILabel *) [currentCell.contentView viewWithTag:103];
label4.text=[[[NSString alloc]initWithFormat:@"%d",qty++] ;
//NSLog(@"%d",row);
[ticketTable reloadData];
}
しかし問題は、ボタンをクリックすると、すべてのセルの数量が増加することです。やり方を教えてください。どんな助けでも大歓迎です。
