我有一个tableview,其中我从2个不同的自定义类加载单元格。我的代码看起来像这样
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier1 = @"CellIdentifier";
static NSString *CellIdentifier2 = @"Cell";
if(messagesarray==nil||[messagesarray count]==0)
{
}
else
{
NSMutableDictionary *dicttable=[messagesarray objectAtIndex:indexPath.row];
NSString *head=[dicttable objectForKey:@"gfgfg"];
NSString *head1=[dicttable objectForKey:@"gfgfgf"];
if([type isEqualToString:@"m"])
{
if([head isEqualToString:@"NA"])
{
CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (cell == nil)
{
cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier1] autorelease];
cell.backgroundView = [ [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:@"white_top_portion.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:5.0] ]autorelease];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.nameLabel.text=head;
cell.msg.text=head1;
[cell.button addTarget:self action:@selector(callAction:) forControlEvents:UIControlEventTouchUpInside];
if(icon!=nil)
{
if(![[ImageCache sharedImageCache] hasImageWithKey:icon])
{
cell.myImageView.image = [UIImage imageNamed:@"fggtgf.png"];
NSArray *myArray = [NSArray arrayWithObjects:cell.myImageView,icon,@"fgfgfg.png",[NSNumber numberWithBool:NO],nil];
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate performSelectorInBackground:@selector(updateImageViewInBackground:) withObject:myArray];
}
else
{
cell.myImageView.image = [[ImageCache sharedImageCache] getImagefromCacheOrUrl:icon];
}
}
else
{
cell.myImageView.image = [UIImage imageNamed:@"fgfgfg.png"];
}
cell.label.text=sub;
return cell;
}
else
{
Customcellwithimage *cell = (Customcellwithimage *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell == nil)
{
cell = [[[Customcellwithimage alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier2] autorelease];
cell.backgroundView = [ [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:@"white_deal_bg.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:5.0] ]autorelease];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.datelabel1.text=subtitle;
cell.nameLabel1.text=head;
cell.msg1.text=head1;
if(icon!=nil)
{
if(![[ImageCache sharedImageCache] hasImageWithKey:icon])
{
cell.myImageView1.image = [UIImage imageNamed:@"fgfgfgf.png"];
NSArray *myArray = [NSArray arrayWithObjects:cell.myImageView1,icon,@"fgfgfgf.png",[NSNumber numberWithBool:NO],nil];
MFAppDelegate *appDelegate = (MFAppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate performSelectorInBackground:@selector(updateImageViewInBackground:) withObject:myArray];
}
else
{
cell.myImageView1.image = [[ImageCache sharedImageCache] getImagefromCacheOrUrl:icon];
}
}
else
{
cell.myImageView1.image = [UIImage imageNamed:@"fgfgfgf.png"];
}
cell.cellview1.image=[UIImage imageNamed:@"vf.png"];
cell.label1.text=sub;
[cell.button1 addTarget:self action:@selector(callAction:) forControlEvents:UIControlEventTouchUpInside];
cell.bannerview1.image=[UIImage imageNamed:@"vfgf.png"];
return cell;
}
}
}
}
我的问题是只有数组中的第一个元素在单元格中重复引用(单元格重复),任何人都可以帮助我知道为什么会发生这种情况。我有数组计数的节数,每个节只有单行。
答案 0 :(得分:2)
如果每个部分只有一行,那么每次调用此方法时indexPath.row
将为0。由于该行是您用来选择数组元素的行,因此它总是相同的是合理的。
如果您为部分数量返回indexPath.section
而对行数返回1,则需要使用[messagesarray count]
。
