copied!<p>Although you can calculate heights for labels contained in table view cells, truly dynamically, in '- layoutSubviews' of a UITableViewCell subclass, there's no similar way of doing this (that I know of) for cell heights in '- tableView:heightForRowAtIndexPath:' of a table view delegate.</p> <p>Consider this:</p> <pre><code>- (void)layoutSubviews { [super layoutSubviews]; CGSize size = [self.textLabel.text sizeWithFont:self.textLabel.font constrainedToSize:CGSizeMake(self.textLabel.$width, CGFLOAT_MAX) lineBreakMode:self.textLabel.lineBreakMode]; self.textLabel.$height = size.height; } </code></pre> <p>Unfortunately though, by the time '- tableView:heightForRowAtIndexPath:' is called, that is too early, because <code>cell.textLabel.frame</code> is yet set to <code>CGRectZero = {{0, 0}, {0, 0}}</code>.</p> <p>AFAIK you won't be able to do this neither with content view's frame, nor summing up individual labels' frames...</p> <p>The only way I can think of is to come up with a convenience class, methods, constants, or such that will try to cover up all possible width in any device orientation, on any device:</p> <pre><code>@interface UITableView (Additions) @property (nonatomic, readonly) CGFloat padding; @end @implementation UITableView (Additions) - (CGFloat)padding { if (self.formStyle == PTFormViewStylePlain) { return 0; } if (self.$width < 20.0) { return self.$width - 10.0; } if (self.$width < 400.0 || [[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { return 10.0; } return MAX(31.0, MIN(45.0, self.$width * 0.06)); } @end </code></pre> <p>Also note that, recently we also have new iPhone 5's 4-inch width (568 instead of 480) in landscape orientation.</p> <p>This whole thing is pretty disturbing, I know... Cheers.</p>
