When developing iOS applications, you may encounter a situation where you need to change the background color of a UIButton while it is highlighted. This typically occurs when a user presses and holds the button. Unfortunately, simply setting the background color does not work as expected in this scenario. This article provides a comprehensive guide on how to achieve this effect using several approaches.
Solution Overview
There are multiple methods to change the background color of a UIButton when it is highlighted. Below, we explore some of the most effective techniques, focusing on a method that overrides the UIButton’s behavior to achieve the desired effect.
Method 1: Override the setHighlighted
Method
One of the most reliable methods is to override the UIButton’s setHighlighted
method. This allows you to customize the background color based on the button’s state.
Objective-C Implementation
- (void)setHighlighted:(BOOL)highlighted {
[super setHighlighted:highlighted];
if (highlighted) {
self.backgroundColor = UIColorFromRGB(0x387038);
} else {
self.backgroundColor = UIColorFromRGB(0x5bb75b);
}
}
Swift Implementation
override open var isHighlighted: Bool {
didSet {
super.isHighlighted = isHighlighted
backgroundColor = isHighlighted ? UIColor.black : UIColor.white
}
}
Method 2: Use UIButton Extensions
Another approach is to use UIButton extensions to set background colors for different states. This method is particularly useful because it allows you to manage colors for various button states efficiently.
extension UIButton {
func setBackgroundColor(_ color: UIColor, for state: UIControl.State) {
let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
UIGraphicsBeginImageContext(rect.size)
color.setFill()
UIRectFill(rect)
let colorImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
setBackgroundImage(colorImage, for: state)
}
}
Conclusion and Further Recommendations
Changing the background color of a UIButton when it is highlighted can significantly enhance the user interface of your application by providing visual feedback. While there are several methods to achieve this, overriding the setHighlighted
method or using UIButton extensions are particularly effective solutions.
