    <p>How long are the strings you're calculating the size against? I ask because you're <code>sizeWithFont:constrainedToSize:</code> function is constraining to the full width of the cell, but your labels are probably not the full width of the cell. </p> <p>What I suspect is happening is <code>song.info</code> is just short enough that it would fit on one line if the line were the full width of the cell, and that your song <code>detail</code> is long enough that it is calculating the correct number of lines, but not so long as to exceed the calculated height.</p> <p>All of that to say, I think what you need to do is find out the widths of <code>textLabel</code> and <code>detailTextLabel</code> and set your constraints to those values.</p> <p><strong>Update - A way of calculating label widths</strong></p> <p>Since the width of the labels inside of a cell are dependent on the width of the cell, and since cell's aren't created at the time <code>heightForRowAtIndexPath:</code> is called, we need to come up with a way to know the labels' widths before they the widths are set. The only way to do this is to set the widths ourselves. Here's how I would do it:</p> <p>MyCell.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface MyCell : UITableViewCell + (CGFloat)textLabelWidthForCellOfWidth:(CGFloat)cellWidth; @end </code></pre> <p>MyCell.m</p> <pre><code>#import "MyCell.h" @implementation MyCell - (void)layoutSubviews { [super layoutSubviews]; CGRect frame = self.textLabel.frame; frame.size.width = [MyCell textLabelWidthForCellOfWidth:self.frame.size.width]; self.textLabel.frame = frame; } + (CGFloat)textLabelWidthForCellOfWidth:(CGFloat)cellWidth { // This calculation can be as complex as necessary to account for all elements that affect the label return cellWidth - 20; } @end </code></pre> <p>Then in your <code>heightForRowAtIndexPath:</code> implementation you can call the same class method:</p> <pre><code>CGFloat labelWidth = [MyCell textLabelWidthForCellOfWidth:self.tableView.frame.size.width]; // Since non-grouped cells are the full width of the tableView CGSize size2 = [detail sizeWithFont:[UIFont fontWithName:setlistFont size:detailFontSize] constrainedToSize:CGSizeMake(labelWidth, CGFLOAT_MAX)]; </code></pre> <p>You would create a separate Class Method (+) for each label that you need to reference.</p>

    1. COThe strings for textLabel aren't long at all, for they are song titles, but the font size for the textLabel is 26.0 right now so they appear large. I changed the constraint width to the width of the textLabel, but heightForRowAtIndexpath gets called before the textLabel is created (creating a runtime error) so I don't think there's a way of accessing the width without hardcoding it? Unless you have any suggestions?

    2. COUnfortunately you're right. Hard coding the values is your simplest option. You could subclass `UITableViewCell` and create class methods that return the appropriate widths and then use those class methods in both `heightForRowAtIndexPath:` and `cellForRowAtIndexPath:` (or in the `layoutSubviews` method of your subclass), but that may be more work than is necessary to do what you're wanting. I'd start with hard coding and grow from there.

    3. COI think your initial theory is correct. When I have song titles that are pretty long, they seem to correctly resize. I will try to find a way to access the width of the textLabel, hopefully without subclassing uitableviewcell.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
