AXStateButton

AXStateButton is a simple UIButton subclass that offers state-based button customization akin to that of Apple's. The idea is nothing fancy, but can be used as the building blocks to create something a bit more complex. All it takes to get started is:

AXStateButton *button = [AXStateButton button];

// some arbitrary customizations
[button setCornerRadius:0.0f forState:UIControlStateNormal];
[button setCornerRadius:6.0f forState:UIControlStateSelected];
[button setCornerRadius:6.0f forState:UIControlStateHighlighted | UIControlStateSelected];

[button setTransformRotationZ:0 forState:UIControlStateNormal];
[button setTransformRotationZ:M_PI_4 forState:UIControlStateSelected];

// customize the rest of your button...

[self.view addSubview:button];

"Well, what properties are state-configurable?"

  • Tint color
  • Background color
  • Alpha
  • Title alpha
  • Image alpha
  • Corner radius
  • Border color
  • Border width
  • Transform rotation (x, y, z)
  • Transform scale
  • Shadow color
  • Shadow opacity
  • Shadow offset
  • Shadow radius
  • Shadow path

Todo?

  • Custom view for state

Other useful things

You can also adjust the animation duration of your state transitions:

button.controlStateAnimationDuration = 0.1;

On top of that, you can change the timing function used when animating control state changes:

button.controlStateAnimationTimingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];

Or, you can disable animations all together:

button.animateControlStateChanges = NO;

For convenience, it's possible to access your set values:

CGFloat cornerRadius = [button cornerRadiusForState:UIControlStateHighlighted | UIControlStateSelected];
// great success!
