Dynamically increase height of UILabel & TableView Cell?

First of all you should not calculate height manually in auto layout environment. Just set both labels TopSpace and BottomSpace to cell's contentView and make sure you set both labels NumberOfLines to 0 and LineBreakMode to WordWrap.

And the other constraint are as below,

ItemLabel:

SeparatorView:

DescriptionLabel:

And add the delegates for height as below,

#pragma mark - UITableView Delegates-(CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath {    return 44.0;}-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {    return UITableViewAutomaticDimension;}

You should get the output as below,

Hope this would help you.

To set automatic dimension for row height & estimated row height, ensure following steps to make, auto dimension effective for cell/row height layout.

• Assign and implement tableview dataSource and delegate
• Assign UITableViewAutomaticDimension to rowHeight & estimatedRowHeight
• Implement delegate/dataSource methods (i.e. heightForRowAt and return a value UITableViewAutomaticDimension to it)

Objective C:

// in ViewController.h#import <UIKit/UIKit.h>@interface ViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>  @property IBOutlet UITableView * table;@end// in ViewController.m- (void)viewDidLoad {    [super viewDidLoad];    self.table.dataSource = self;    self.table.delegate = self;    self.table.rowHeight = UITableViewAutomaticDimension;    self.table.estimatedRowHeight = UITableViewAutomaticDimension;}-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {    return UITableViewAutomaticDimension;}

Swift:

@IBOutlet weak var table: UITableView!override func viewDidLoad() {    super.viewDidLoad()    // Don't forget to set dataSource and delegate for table    table.dataSource = self    table.delegate = self   // Set automatic dimensions for row height    // Swift 4.2 onwards    table.rowHeight = UITableView.automaticDimension    table.estimatedRowHeight = UITableView.automaticDimension    // Swift 4.1 and below    table.rowHeight = UITableViewAutomaticDimension    table.estimatedRowHeight = UITableViewAutomaticDimension}// UITableViewAutomaticDimension calculates height of label contents/textfunc tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {    // Swift 4.2 onwards    return UITableView.automaticDimension    // Swift 4.1 and below    return UITableViewAutomaticDimension}

For label instance in UITableviewCell

• Set number of lines = 0 (& line break mode = truncate tail)
• Set all constraints (top, bottom, right left) with respect to its superview/ cell container.
• Optional: Set minimum height for label, if you want minimum vertical area covered by label, even if there is no data.

Note: If you've more than one labels (UIElements) with dynamic length, which should be adjusted according to its content size: Adjust 'Content Hugging and Compression Resistance Priority` for labels which you want to expand/compress with higher priority.

You need to define maximum estimated Height when view is loading

tblObject.estimatedRowHeight = 300;tblObject.rowHeight = UITableViewAutomaticDimension;
