Change UIButton border color on highlight


You were on the right track. Check the code below, it elaborates on this, but what you'll want to do is link selectors to different control events on your button. One for touchDown to change the shadow to red, and another for touchUpInside to change the shadow back when you lift your finger.

Additionally, I see you've asked several questions on Stack Overflow and have yet to mark any as the correct answer. To continue to receive help on this website, you will need to start marking correct answers to your questions.

[myButton addTarget:self action:@selector(highlightBorder) forControlEvents:UIControlEventTouchDown];[myButton addTarget:self action:@selector(unhighlightBorder) forControlEvents:UIControlEventTouchUpInside];- (void)highlightBorder{    myButton.layer.borderColor = [[UIColor redColor]CGColor];}- (void)unhighlightBorder{    myButton.layer.borderColor = [[UIColor blueColor]CGColor];    //additional code for an action when the button is released can go here.}

NOTE: Other options for UIControlEvents include:

enum {   UIControlEventTouchDown           = 1 <<  0,   UIControlEventTouchDownRepeat     = 1 <<  1,   UIControlEventTouchDragInside     = 1 <<  2,   UIControlEventTouchDragOutside    = 1 <<  3,   UIControlEventTouchDragEnter      = 1 <<  4,   UIControlEventTouchDragExit       = 1 <<  5,   UIControlEventTouchUpInside       = 1 <<  6,   UIControlEventTouchUpOutside      = 1 <<  7,   UIControlEventTouchCancel         = 1 <<  8,   UIControlEventValueChanged        = 1 << 12,   UIControlEventEditingDidBegin     = 1 << 16,   UIControlEventEditingChanged      = 1 << 17,   UIControlEventEditingDidEnd       = 1 << 18,   UIControlEventEditingDidEndOnExit = 1 << 19,   UIControlEventAllTouchEvents      = 0x00000FFF,   UIControlEventAllEditingEvents    = 0x000F0000,   UIControlEventApplicationReserved = 0x0F000000,   UIControlEventSystemReserved      = 0xF0000000,   UIControlEventAllEvents           = 0xFFFFFFFF};


The SWIFT 2.x answer to your problem:

➜ Just override the highlighted property with "didSet" observer.

override var highlighted: Bool {    didSet {        switch highlighted {        case true:            layer.borderColor = UIColor.lightGrayColor().CGColor        case false:            layer.borderColor = UIColor.blackColor().CGColor        }    }}

Swift 3:

override var isHighlighted: Bool {    didSet {        switch isHighlighted {        case true:            layer.borderColor = UIColor.lightGray.cgColor        case false:            layer.borderColor = UIColor.black.cgColor        }    }}


You can override setHighlighted and setSelected methods in UIButton subclass. From there you just tweak border color like following:

- (void)setHighlighted:(BOOL)highlighted {    [super setHighlighted:highlighted];    [self tweakState:highlighted];}- (void)setSelected:(BOOL)selected {    [super setSelected:selected];    [self tweakState:selected];}- (void)tweakState:(BOOL)state {    if (state) {        self.layer.borderColor = [_highlightedBorderColor CGColor];    }    else {        self.layer.borderColor = [_defaultBorderColor CGColor];    }}
