我使用以下代码为索引路径处的每一行实现单元格:但问题是当我滚动 tableView 时,单元格会在一行中的一个单元格中加载大量 UIImageView *itemimageview,我尝试使用
for (UIImageView *sView in cell.subviews) {
[sView removeFromSuperview];
}
但它会删除一个单元格的所有子视图。如何解决这个问题呢?...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSUInteger row = [indexPath row];
NSUInteger oldRow = [lastIndexPath row];
static NSString *CheckMarkCellIdentifier = @"CheckMarkCellIdentifier";
//dequeueReusableCellWithIdentifier --
// Returns a reusable table-view cell object located by its identifier.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CheckMarkCellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CheckMarkCellIdentifier] autorelease];
}
/*
for (UIImageView *sView in cell.subviews) {
[sView removeFromSuperview];
}
*/
UIImageView *itemimageview=[[UIImageView alloc]initWithFrame:CGRectMake(5, 5, 232, 54)];
itemimageview.image=[UIImage imageNamed:[tabsImageArray objectAtIndex:row]];
itemimageview.userInteractionEnabled = YES;
[cell.contentView addSubview:itemimageview];
[itemimageview release];
UIImageView *dictIcon=[[UIImageView alloc]initWithFrame:CGRectMake(30, 18, 30, 30)];
dictIcon.image=[UIImage imageNamed:@"dictionary_icon.png"];
dictIcon.userInteractionEnabled = YES;
[cell.contentView addSubview:dictIcon];
[dictIcon release];
UILabel *dictNameLabel = [[UILabel alloc] initWithFrame:CGRectMake(80, 23, 100, 21)];
dictNameLabel.text = dictName;
dictNameLabel.textColor = [UIColor whiteColor];
dictNameLabel.shadowColor = [UIColor blackColor];
dictNameLabel.backgroundColor = [UIColor clearColor];
dictNameLabel.userInteractionEnabled = YES;
[cell.contentView addSubview:dictNameLabel];
[dictNameLabel release];
//cell.textLabel.text = [tabsImageArray objectAtIndex:row];
cell.accessoryType = (row == oldRow && lastIndexPath != nil) ? UITableViewCellAccessoryCheckmark : UITableViewCellAccessoryNone;
return cell;
}
