You can override UIButton‘s setHighlighted method. Objective-C – (void)setHighlighted:(BOOL)highlighted { [super setHighlighted:highlighted]; if (highlighted) { self.backgroundColor = UIColorFromRGB(0x387038); } else { self.backgroundColor = UIColorFromRGB(0x5bb75b); } } Swift 3.0 and Swift 4.1 override open var isHighlighted: Bool { didSet { backgroundColor = isHighlighted ? UIColor.black : UIColor.white } }
Here’s one: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; [button addTarget:self action:@selector(aMethod:) forControlEvents:UIControlEventTouchUpInside]; [button setTitle:@”Show View” forState:UIControlStateNormal]; button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0); [view addSubview:button];
In Apple’s Accessory sample the following method is used: [button addTarget:self action:@selector(checkButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; Then in touch handler touch coordinate retrieved and index path is calculated from that coordinate: – (void)checkButtonTapped:(id)sender { CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView]; NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition]; if (indexPath != nil) { … } }
Programmatically: let image = UIImage(named: “image”) btn.setImage(btnImage , forState: .normal) Storyboard: Select your image > Attributes inspector > Image
You can’t pass arguments when you use @selector. @selector(buttonClicked:WithString:title) // This here is invalid^^ That operator can only be used on a method name; the selector you get from it is later used to call the method, at which point arguments can be passed.
You don’t need to add () to the end of a method when you are passing that method as a selector! This is because () is used to specify the arguments when you are calling the method. But you don’t want to call the method, do you? So remove the ()! //Adding BUtton let btn … Read more
