我真的遇到了将UIImageView添加到单个UITableView单元的麻烦。在我的Storyboard中,我有一个UITableViewController和四个原型动态单元格。其中三个像普通的左细节细胞一样好,它们工作正常。但是其中一个我需要有一个UIImageView。
所以我已经将所述视图添加到单元格,给定单元格一个带有属性的自定义类,以便我可以访问图像视图。
我有以下单元格:
标题单元格
Image Cell。
URL Cell。
备注细胞。
表视图的内容会根据用户是否要添加URL,注释或图像而更改。因此,用户总是会看到标题单元格中的一个。
这是我的代码,无论出于什么原因,我都无法在该图像单元格上显示UIImageView。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
//0 = Image
if ([[NSUserDefaults standardUserDefaults] integerForKey:@"NewScrapbookEntry"] == 0)
{
if (indexPath.row == 0) CellIdentifier = @"titleCell";
if (indexPath.row == 1) CellIdentifier = @"imageCell";
if (indexPath.row == 2) CellIdentifier = @"notesCell";
}
//1 = URL
else if ([[NSUserDefaults standardUserDefaults] integerForKey:@"NewScrapbookEntry"] == 1)
{
if (indexPath.row == 0) CellIdentifier = @"titleCell";
if (indexPath.row == 1) CellIdentifier = @"urlCell";
if (indexPath.row == 2) CellIdentifier = @"notesCell";
}
//2 = Notes
else if ([[NSUserDefaults standardUserDefaults] integerForKey:@"NewScrapbookEntry"] == 2)
{
if (indexPath.row == 0) CellIdentifier = @"titleCell";
if (indexPath.row == 1) CellIdentifier = @"notesCell";
}
ScrapbookImageDetailCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[ScrapbookImageDetailCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:CellIdentifier];
cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
[cell setBackgroundColor:[UIColor colorWithRed:250.0f/255.0f green:250.0f/255.0f blue:250.0f/255.0f alpha:1.0f]];
[cell setSelectionStyle:UITableViewCellSelectionStyleGray];
cell.textLabel.adjustsFontSizeToFitWidth = YES;
cell.textLabel.text = [firstSection objectAtIndex:indexPath.row];
cell.detailTextLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:13.0f];
cell.detailTextLabel.numberOfLines = 0;
cell.accessoryView = nil;
switch (indexPath.section)
{
case 0:
switch (indexPath.row)
{
case 0:
{
cell.detailTextLabel.text = scrapbook.title;
}
break;
case 1:
{
//0 = Image
if ([[NSUserDefaults standardUserDefaults] integerForKey:@"NewScrapbookEntry"] == 0)
{
cell.detailTextLabel.text = nil;
cell.iv.image = [UIImage imageNamed:@"image.png"];
}
//1 = URL
else if ([[NSUserDefaults standardUserDefaults] integerForKey:@"NewScrapbookEntry"] == 1)
{
cell.detailTextLabel.text = scrapbook.url;
}
//2 = Notes
else if ([[NSUserDefaults standardUserDefaults] integerForKey:@"NewScrapbookEntry"] == 2)
{
cell.detailTextLabel.text = scrapbook.notes;
}
}
break;
case 2:
{
cell.detailTextLabel.text = scrapbook.notes;
}
break;
default:
break;
}
break;
default:
break;
}
return cell;
}

为什么要更改标识符值?您需要做的就是制作自定义单元格,并在行高,检查它是否是您想要的行,并返回图像高度,否则默认大小,并在单元格行方法,再次检查所需的行并添加图像你想添加其他使得imageview无。
