UITableVIewCell重疊圖像中的自定義按鈕

Question

我在UITableViewCell的每個單元格中添加了一個自定義按鈕。該按鈕的類型是custom.I已將圖像添加到此按鈕。當用戶選擇此按鈕時，其圖像被更改。但是這些按鈕的圖像是重疊的。以下是我的代碼。

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

static NSString *CellIdentifier = @"CountryCell"; 

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


} 

// Configure the cell... 

cell.textLabel.lineBreakMode = UILineBreakModeWordWrap; 
cell.textLabel.numberOfLines = 0; 
cell.selectionStyle = UITableViewCellSelectionStyleNone ; 
cell.textLabel.text = [[_listArray objectAtIndex:indexPath.row] wish]; 
cell.textLabel.textColor = [UIColor whiteColor]; 

CustomWishButton *newBtn = [CustomWishButton buttonWithType:UIButtonTypeCustom]; 
[newBtn setFrame:CGRectMake(280,5,35,34)]; 
cell.textLabel.font = [UIFont fontWithName:@"Times New Roman" size:21]; 
newBtn.customString = [[_listArray objectAtIndex:indexPath.row] wish] ; 
newBtn.customStatus = [[_listArray objectAtIndex:indexPath.row] status]; 
newBtn.imageName = [[_listArray objectAtIndex:indexPath.row]imageName]; 

[newBtn setImage:[UIImage imageNamed:newBtn.imageName] forState:UIControlStateNormal]; 
[newBtn addTarget:self action:@selector(changeStatus:) forControlEvents:UIControlEventTouchUpInside]; 

[cell addSubview:newBtn]; 

return cell; 
} 

-(void)changeStatus:(id)sender{ 

    CustomWishButton *resultButton= (CustomWishButton*)sender; 

if ([resultButton.imageName isEqualToString:@"cancel.png"]) { 

    NSString *wish = resultButton.customString; 

    NSLog(@"wish: %@",wish); 

    [sql updateData:wish:1:@"tick.png"]; 


} 
else{ 


    NSString *wish = resultButton.customString; 



    [sql updateData:wish:0:@"cancel.png"]; 
} 

_listArray = [sql getList]; 

[wishTableView reloadData]; 
}

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
    { 
     NSString *CellIdentifier = [NSString stringWithFormat:@"CountryCell%d",indexPath.row]; 

     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

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

      //CustomWishButton shouldn't add each and everytime! So why I kept inside. 
      CustomWishButton *newBtn = [CustomWishButton buttonWithType:UIButtonTypeCustom]; 
      [newBtn setFrame:CGRectMake(280,5,35,34)]; 
      cell.textLabel.font = [UIFont fontWithName:@"Times New Roman" size:21]; 
      newBtn.customString = [[_listArray objectAtIndex:indexPath.row] wish] ; 
      newBtn.customStatus = [[_listArray objectAtIndex:indexPath.row] status]; 
      newBtn.imageName = [[_listArray objectAtIndex:indexPath.row]imageName]; 

      [newBtn setImage:[UIImage imageNamed:newBtn.imageName] forState:UIControlStateNormal]; 
      [newBtn addTarget:self action:@selector(changeStatus:) forControlEvents:UIControlEventTouchUpInside]; 

      [cell addSubview:newBtn]; 
     } 

     // Configure the cell... 

     cell.textLabel.lineBreakMode = UILineBreakModeWordWrap; 
     cell.textLabel.numberOfLines = 0; 
     cell.selectionStyle = UITableViewCellSelectionStyleNone ; 
     cell.textLabel.text = [[_listArray objectAtIndex:indexPath.row] wish]; 
     cell.textLabel.textColor = [UIColor whiteColor]; 


     return cell; 
    } 

    //instead of (id) reference I make it your CustomWishButton reference 
    -(void)changeStatus:(CustomWishButton *)resultButton 
    { 
     if ([resultButton.imageName isEqualToString:@"cancel.png"]) 
     { 
      NSString *wish = resultButton.customString; 

      NSLog(@"wish: %@",wish); 

      [sql updateData:wish:1:@"tick.png"]; 
     } 
     else 
     { 
      NSString *wish = resultButton.customString; 
      [sql updateData:wish:0:@"cancel.png"]; 

     } 

     //Change image as per your condition 
     [resultButton setImage:[UIImage imageNamed:NewImageName] forState:UIControlStateNormal]; 

     _listArray = [sql getList]; 

     [wishTableView reloadData]; 
    }
