iOS UI相关之UITableView的高度计算02-自适应

- (CGFloat)textViewHeightWithIndexPath:(NSIndexPath *)indexPath{
    //对于textView来说，其高度对于systemLayoutSizeFittingSize:方法不起作用，所以需要另加
    IMTableViewCell02 *cell = (IMTableViewCell02 *)self.prototypeCell;
    cell.textView.text = self.dataArray[indexPath.row];
    CGSize size = [cell systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
    CGFloat textViewH = [cell.textView sizeThatFits:CGSizeMake(400, MAXFLOAT)].height;
    return size.height + textViewH;
}



- (CGFloat)labelHeightWithIndexPath:(NSIndexPath *)indexPath{
    IMTableViewCell01 *cell = (IMTableViewCell01 *)self.prototypeCell;
    cell.label.text = self.dataArray[indexPath.row];
    NSLog(@"text---%@", self.dataArray[indexPath.row]);
    CGSize size = [cell systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
    return size.height;
}
