This Swift and Objective-C! UIButton was made inspired in Google new Material Design, and this GIF :]

**You need to add the ZMaterialButtonDelegate to your Controller:**
class ViewController: UIViewController, ZMaterialButtonDelegate {
}**To create a Material UIButton init it with frame and set the Zdelegate, a .endPoint (CGPoint) and a .changeToImage (UIImage)**
```swift let containerView = UIView(frame: CGRect(x: 0, y: 200, width: self.view.frame.size.width, height: self.view.frame.size.height-200)) containerView.clipsToBounds = true self.view.addSubview(containerView)
self.button = ZMaterialButton(frame: CGRect(x: 10, y: 40, width: 100, height: 100)) self.button.setImage(UIImage(named: "play"), forState: UIControlState.Normal) self.button.backgroundColor = UIColor(red:0.05, green:0.69, blue:0.79, alpha:1) self.button.endPoint = CGPoint(x:self.view.center.x-50, y: self.view.center.y-50) self.button.changeToImage = UIImage(named: "pause") self.button.Zdelegate = self containerView.addSubview(self.button)
<h6>Obj-C</h6>
``` obj-c
ZMaterialButton *ZButton = [[ZMaterialButton alloc]initWithFrame:CGRectMake(40, 40, 50, 50)];
[ZButton setImage:[UIImage imageNamed:@"play"] forState:UIControlStateNormal];
[ZButton setBackgroundColor:[UIColor redColor]];
[ZButton setEndAnimationPoint:CGPointMake(self.view.center.x-25, self.view.center.y-25)];
ZButton.changeToImage = [UIImage imageNamed:@"pause"];
ZButton.expandBy = 20;
ZButton.originalParentViewColor = [UIColor whiteColor];
ZButton.delegate = self;
[self.view addSubview:ZButton];
**Add the delegate function ZMaterialButtonDidExpand() to your controller to know when the button expanded or reduced.**
```swift func ZMaterialButtonDidExpand(button: ZMaterialButton, expanded: Bool){ if expanded == true { self.testButtonExpanded() UIView.animateWithDuration(0.1, delay: 0, options: .CurveEaseOut, animations: { self.fButton.alpha = 1 self.bButton.alpha = 1 }, completion:nil) } else { self.testButtonReduced() UIView.animateWithDuration(0.2, delay: 0, options: .CurveEaseOut, animations: { self.fButton.alpha = 0 self.bButton.alpha = 0 }, completion:nil) } } ``` ```obj-c - (void) ZMaterialButtonDidExpandButton:(ZMaterialButton *)button withSuccces:(BOOL)success{ if (success) { NSLog(@"Expanded"); } else { NSLog(@"Reduced"); } } ```
