我有一个列表视图,有时会有长文本。当文本是几段时,它往往会在某个时候被切断。奇怪的行为的一部分是它不总是在同一个字符上被截断,而是随机的。ios - 列表项在一定长度后有文本截断
这里是我用来填充列表代码:
// CREATING EACH CELL IN THE LIST
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//static const NSInteger kLabelTag = 1;
UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:(UITableViewCellStyleDefault)
reuseIdentifier:@"business"];
NSString *comment = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"comment")];
NSString *first_name = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"first_name")];
//Boolean *is_private = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"is_private")];
// Creating a constraint size for the label you are making
CGSize constraint = CGSizeMake(320 - (10 * 2), 20000.0f);
// Determining the size that you will need for the label based on the comment
// length and the contraint size
CGSize size = [comment sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
// Creating the label and initializing it with the frame that you have
// determined by your size calculations above
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, MAX(size.height, 44.0f) + 20.0f)];
// setting up the label properties
label.numberOfLines = 0;
label.lineBreakMode = UILineBreakModeWordWrap;
standardUserDefaults = [NSUserDefaults standardUserDefaults];
NSString *is_private = [standardUserDefaults objectForKey:@"is_private"];
if (is_private == nil)
{
label.text = [first_name stringByAppendingString:[@": " stringByAppendingString:comment]]; // comment;
}
else
if ([is_private isEqualToString:@"0"])
{
label.text = [first_name stringByAppendingString:[@": " stringByAppendingString:comment]]; // comment;
}
else
{
label.text = comment;
}
// adding the label view to the cell that you have created
[cell.contentView addSubview:label];
// CLOSE THE SPINNER
[spinner stopAnimating];
// return the cell for the table view
return cell;
}
//This method will determine how tall each row needs to be. Cell size for word wrapping.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSString *comment = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"comment")];
// Again you are getting the constraints because you are going to us this size
// to constrain the height of the cell just like you determined the size for the label.
CGSize constraint = CGSizeMake(320 - (10 * 2), 20000.0f);
// Again, determining the size that we will need for the label, because it will drive
// the height of the cell
CGSize size = [comment sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
// Finally, we can determine the height for the cell!
CGFloat height = MAX(size.height, 44.0f);
// return the height, which is the height of the label plus some extra space to make
// it look good.
return height + (10 * 2);
}
此代码是否有任何与它特别不正确的?或者问题可能是其他地方的根源?
谢谢!
我想改变高度为标签的动态高度可能是最好的在这里。有没有简单的方法来做到这一点? – GeekedOut
这里有点难,因为你是从代码构建你的UI,而不是在可视化编辑器中。 我会更新答案 –
谢谢你的帮助:) – GeekedOut
