UITableView에서 UIButton의 선택된 상태

Question

UITableView의 각 셀에 UIButton이 있습니다. 내가 만질 때, 그 상태는 선택되도록 설정됩니다. 그러나 테이블보기를 스크롤하여 단추가 보이지 않도록 상태를 보통으로 설정합니다. UIButton이 선택된 상태에서 어떻게해야합니까?

감사합니다.

편집 :

- (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] autorelease]; 
} 

cell.selectionStyle = UITableViewCellSelectionStyleNone; 

if (indexPath.row < [messagesArray count]) { 

    Zprava *msgObj = [messagesArray objectAtIndex:indexPath.row]; 

    int width = 0; 

    if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait) { 
     width = 320; 
    } else { 
     width = 480; 
    } 

    CGSize boundingSize = CGSizeMake(width, CGFLOAT_MAX); 
    CGSize requiredSize = [msgObj.mmessage sizeWithFont:[UIFont systemFontOfSize:17] constrainedToSize:boundingSize lineBreakMode:UILineBreakModeWordWrap]; 

    UIButton *background = [[UIButton alloc] initWithFrame:CGRectMake(10, 25, 300, requiredSize.height + 20)]; 
    [background setBackgroundImage:[[UIImage imageNamed:@"balloon.png"] stretchableImageWithLeftCapWidth:15 topCapHeight:15] forState:UIControlStateNormal]; 
    [background setBackgroundImage:[[UIImage imageNamed:@"selected-balloon.png"] stretchableImageWithLeftCapWidth:15 topCapHeight:15] forState:UIControlStateSelected]; 
    [background addTarget:self action:@selector(action:) forControlEvents:UIControlEventTouchUpInside]; 
    background.tag = msgObj.msgID; 
    [[cell contentView] addSubview:background]; 
    [background release]; 

    UILabel *dateLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 285, 15)]; 
    [dateLabel setFont:[UIFont systemFontOfSize:12]]; 
    [dateLabel setLineBreakMode:UILineBreakModeWordWrap]; 
    [dateLabel setTextColor:[UIColor lightGrayColor]]; 
    [dateLabel setNumberOfLines:0]; 
    [dateLabel setTextAlignment:UITextAlignmentRight]; 
    [dateLabel setText:msgObj.mdate]; 
    [dateLabel setBackgroundColor:[UIColor clearColor]];  
    [dateLabel setOpaque:NO]; 
    [[cell contentView] addSubview:dateLabel]; 
    [dateLabel release]; 

    UILabel *messageLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 30, 275, requiredSize.height + 5)]; 
    [messageLabel setFont:[UIFont systemFontOfSize:17]]; 
    [messageLabel setLineBreakMode:UILineBreakModeWordWrap]; 
    [messageLabel setTextColor:[UIColor blackColor]]; 
    [messageLabel setNumberOfLines:0]; 
    [messageLabel setText:msgObj.mmessage]; 
    [messageLabel setBackgroundColor:[UIColor clearColor]]; 
    [messageLabel setOpaque:NO]; 
    [[cell contentView] addSubview:messageLabel]; 
    [messageLabel release]; 

} 

return cell; 

}

저장 버튼 상태 어딘가에 모델의 별도 테이블보기에서 다시 cellForRowAtIndexpath: 방법에 버튼 상태를 설정 : 다음은 cellForRowAtIndexPath 코드입니다.
