根据这tutorial,我有一个UITextView
内UITableViewCell
。当UITableView
已加载时,我想要UITextView
和UITableViewCell
调整它们的高度。UITextView里面的UITableViewCell
但是我根据教程所做的一切,UITextView
无法显示全部内容,部分UITextView
内容仍然需要滚动显示。
这里是我的代码:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *contentTableIdentify = @"contentTableIdentify";
UITableViewCell *cell = nil;
//UILabel *label = nil;
UITextView *textView = nil;
cell = [self.tableView dequeueReusableCellWithIdentifier:contentTableIdentify];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:contentTableIdentify];
textView = [[UITextView alloc] initWithFrame:CGRectZero];
[textView setTextColor:[UIColor blackColor]];
[textView setFont:[UIFont fontWithName:@"Helvetica" size:12.0f]];
[textView setBackgroundColor:[UIColor clearColor]];
[textView setTag:1];
[textView setEditable:NO];
[[cell contentView] addSubview:textView];
}
NSString *text = [self.contentArray objectAtIndex:[indexPath row]];
CGSize constraint = CGSizeMake(320 - (10 * 2), 99999.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:12.0f] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping];
if (!textView)
textView = (UITextView *)[cell viewWithTag:1];
[textView setText:text];
[textView setFrame:CGRectMake(10, 10, 320 - (10 * 2), MAX(size.height, 44.0f))];
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *text = [self.contentArray objectAtIndex:[indexPath row]];
CGSize constraint = CGSizeMake(320 - (10 * 2), 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:12] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping];
CGFloat height = MAX(size.height, 44.0f);
return height + (10 * 2);
}
您是否在故事板中制作此单元格,并且您是否使用自动布局? – rdelmar
