You can manipulate the CALayer of your button to do this pretty easily. // assuming you have a UIButton or more generally a UIView called buyButton buyButton.layer.cornerRadius = 2; buyButton.layer.borderWidth = 1; buyButton.layer.borderColor = [UIColor blueColor].CGColor; // (note – may prefer to use the tintColor of the control) you can tweak each of those to … Read more
Your code should look like below let image = UIImage(named: “name”) as UIImage? let button = UIButton(type: UIButtonType.Custom) as UIButton button.frame = CGRectMake(100, 100, 100, 100) button.setImage(image, forState: .Normal) button.addTarget(self, action: “btnTouched:”, forControlEvents:.TouchUpInside) self.view.addSubview(button)
There is only one tiny mistake in the question that causes the shadow to not be displayed: masksToBounds:YES also masks the shadow! Here’s the correct code: self.layer.cornerRadius = 8.0f; self.layer.masksToBounds = NO; self.layer.borderWidth = 1.0f; self.layer.shadowColor = [UIColor greenColor].CGColor; self.layer.shadowOpacity = 0.8; self.layer.shadowRadius = 12; self.layer.shadowOffset = CGSizeMake(12.0f, 12.0f); Unfortunately, this means we cannot mask … Read more
This solution works with Swift 3 and respects original content and image edge insets while keeping the title label always centered in the available space, which makes much easier adjusting margins. It overrides titleRect(forContentRect:) method and returns the correct frame: @IBDesignable class LeftAlignedIconButton: UIButton { override func titleRect(forContentRect contentRect: CGRect) -> CGRect { let titleRect … Read more
you could use a SKSpriteNode as your button, and then when the user touches, check if that was the node touched. Use the SKSpriteNode’s name property to identify the node: //fire button – (SKSpriteNode *)fireButtonNode { SKSpriteNode *fireNode = [SKSpriteNode spriteNodeWithImageNamed:@”fireButton.png”]; fireNode.position = CGPointMake(fireButtonX,fireButtonY); fireNode.name = @”fireButtonNode”;//how the node is identified later fireNode.zPosition = 1.0; … Read more
For the original poster, here is the solution I found: commentButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentFill; This will allow your button to scale horizontally. There is a vertical setting as well. Took me several hours to figure that one out (the naming of the property is very unintuitive) so figured I’d share.
For Swift: Swift 3: extension UIView { @IBInspectable var cornerRadius: CGFloat { get { return layer.cornerRadius } set { layer.cornerRadius = newValue layer.masksToBounds = newValue > 0 } } @IBInspectable var borderWidth: CGFloat { get { return layer.borderWidth } set { layer.borderWidth = newValue } } @IBInspectable var borderColor: UIColor? { get { return UIColor(cgColor: … Read more

With iOS 5+ it’s as easy as: UIBarButtonItem *btnShare = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(share)]; UIBarButtonItem *btnRefresh = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refresh)]; [self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:btnShare, btnRefresh, nil]];
