How can I increase the Tap Area for UIButton?

You can simply adjust the content inset of the button to get your desired size. In code, it will look like this:

button.contentEdgeInsets = UIEdgeInsets(top: 12, left: 16, bottom: 12, right: 16)//Or if you specifically want to adjust around the image, instead use button.imageEdgeInsets

In interface builder, it will look like this:

Very easy. Create a custom UIButton class. Then override pointInside... method and change the value as you want.

#import "CustomButton.h"@implementation CustomButton-(BOOL) pointInside:(CGPoint)point withEvent:(UIEvent *)event{    CGRect newArea = CGRectMake(self.bounds.origin.x - 10, self.bounds.origin.y - 10, self.bounds.size.width + 20, self.bounds.size.height + 20);        return CGRectContainsPoint(newArea, point);}@end

It will take more 10 points touch area for every side.

And Swift 5 version:

class CustomButton: UIButton {    override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {        return bounds.insetBy(dx: -10, dy: -10).contains(point)    }}

I confirm that Syed's solution works well even with autolayout. Here's the Swift 4.x version:

import UIKitclass BeepSmallButton: UIButton {    // MARK: - Functions    override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {        let newArea = CGRect(            x: self.bounds.origin.x - 5.0,            y: self.bounds.origin.y - 5.0,            width: self.bounds.size.width + 10.0,            height: self.bounds.size.height + 20.0        )        return newArea.contains(point)    }    override init(frame: CGRect) {        super.init(frame: frame)    }    required init?(coder aDecoder: NSCoder) {        fatalError("init(coder:) has not been implemented")    }}
