我已经按照我在stackoverflow上找到的说明来修复以下内容,但没有一个有效。以下是我的代码:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"DoCCell";
DoCCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[DoCCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
CGSize constraintSize = CGSizeMake(cell.infoLabel.frame.size.width, MAXFLOAT);
CGSize labelSize = [_content[[indexPath row] * 2] sizeWithFont:[UIFont fontWithName:@"HelveticaNeue-Light" size:12.0f]
constrainedToSize:constraintSize
lineBreakMode:NSLineBreakByWordWrapping];
CGRect frame = CGRectMake (cell.infoLabel.frame.origin.x, cell.infoLabel.frame.origin.y, labelSize.width, labelSize.height);
[cell.infoLabel setFrame:frame];
cell.infoLabel.lineBreakMode = NSLineBreakByWordWrapping;
cell.infoLabel.numberOfLines = 10;
_font = cell.infoLabel.font;
cell.infoLabel.text = _content[[indexPath row] * 2];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGSize constraintSize = CGSizeMake(280.0f, MAXFLOAT);
CGSize size = [_content[[indexPath row] * 2] sizeWithFont:[UIFont fontWithName:@"HelveticaNeue-Light" size:12.0f]
constrainedToSize:constraintSize
lineBreakMode:NSLineBreakByWordWrapping];
return size.height + 30.0;
}
但是当我运行我的代码时,单元格的高度会被适当地更改,而标签大小却没有。
单元格是自定义单元格,我通过.xib文件添加了标签。我尝试手动拉伸标签,因为它会显示所有文本,因此问题不在标签的包装中。我还测试了cell.infoLabel.frame.size.height,并且高度值DOES随着单元格的高度而变化,只要该值有关,但它不会这样显示。我做错了什么?

我认为问题可能是调整UILabel实例中文本的垂直对齐方式。
我认为你应该在cellForRowAtIndexPath中执行以下操作:
cell.infoLabel.text = _content[[indexPath row] * 2];
cell.infoLabel.numberOfLines = 0;
[cell.infoLabel sizeToFit];

希望这有帮助! :)

在tableView的cellForRowAtIndexPath委托中使用以下代码:
// getDynamicHeight function calculates height based on text length
//Dynamically determine height for cell text
CGFloat calculatedHeight = [self getDynamicHeight:@"Some very long text here"];
//Set name label frame based on text height
cell.infoLabel.frame = CGRectMake(cell.infoLabel.frame.origin.x,cell.infoLabel.frame.origin.y, cell.infoLabel.frame.size.width,calculatedHeight);
cell.infoLabel.numberOfLines = 5;
cell.infoLabel.text = @"Some very long text here";
// getDynamicHeight function
//Dynamically determine height for cell based in containing Text
-(CGFloat) getDynamicHeight : (NSString *) strCellTextName {
UILabel *lblGetDynamicHeight = [[UILabel alloc] init];
lblGetDynamicHeight.lineBreakMode = UILineBreakModeWordWrap;
lblGetDynamicHeight.text = strCellTextName;
CGSize labelStringSize = [lblGetDynamicHeight.text sizeWithFont:lblGetDynamicHeight.font constrainedToSize:CGSizeMake(142, 9999) lineBreakMode:lblGetDynamicHeight.lineBreakMode];
return labelStringSize.height; }
