Add subview with UIAlertVIew like animation,with a bouncing effect - iphone

Question

How to give a bounce or pop up style animation while adding a subview in iOS?
I need something similar to UIAlertView appearance style. I know there are several methods to do the same: but I prefer to use basic [UIView animateWithDuration: ...]; block here, so may I get some help regarding the transform I should use here to get the pop up effect?
Thanks

Answer 1

Animation for PopUp style :
Swift
yourView.transform = CGAffineTransform(scaleX: 0.01, y: 0.01)
UIView.animate(withDuration: 0.2, delay: 0, options: .curveEaseOut, animations: {() -> Void in
yourView.transform = .identity
}, completion: {(finished: Bool) -> Void in
// do something once the animation finishes, put it here
})
Reverse Animation with hiding the same View
yourView.transform = .identity
UIView.animate(withDuration: 0.2, delay: 0, options: .curveEaseOut, animations: {() -> Void in
yourView.transform = CGAffineTransform(scaleX: 0.01, y: 0.01)
}, completion: {(finished: Bool) -> Void in
// do something once the animation finishes, put it here
yourView.isHidden = true
})
Objective-C
yourView.transform = CGAffineTransformMakeScale(0.01, 0.01);
[UIView animateWithDuration:0.2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
yourView.transform = CGAffineTransformIdentity;
} completion:^(BOOL finished){
// do something once the animation finishes, put it here
}];
Reverse Animation with hiding the same View
yourView.transform = CGAffineTransformIdentity;
[UIView animateWithDuration:0.2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
yourView.transform = CGAffineTransformMakeScale(0.01, 0.01);
} completion:^(BOOL finished){
yourView.hidden = YES;
}];

I had already done before ... you can get my idea from this code . this may help you. if you have any problem, please let me know.thanks
- (CGAffineTransform)transformForOrientation {
UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
if (orientation == UIInterfaceOrientationLandscapeLeft) {
return CGAffineTransformMakeRotation(M_PI*1.5);
} else if (orientation == UIInterfaceOrientationLandscapeRight) {
return CGAffineTransformMakeRotation(M_PI/2);
} else if (orientation == UIInterfaceOrientationPortraitUpsideDown) {
return CGAffineTransformMakeRotation(-M_PI);
} else {
return CGAffineTransformIdentity;
}
}
-(void)showCustomAlertView{
UIWindow *window = [UIApplication sharedApplication].keyWindow;
//self (this view pop up like alert)
[window addSubview:self];
self.transform = CGAffineTransformScale([self transformForOrientation], 0.001, 0.001);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/1.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(bounce1AnimationStopped)];
self.transform = CGAffineTransformScale([self transformForOrientation], 1.1, 1.1);
[UIView commitAnimations];
}
- (void)bounce1AnimationStopped {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/2];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(bounce2AnimationStopped)];
self.transform = CGAffineTransformScale([self transformForOrientation], 0.9, 0.9);
[UIView commitAnimations];
}
- (void)bounce2AnimationStopped {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/2];
self.transform = [self transformForOrientation];
[UIView commitAnimations];
}

Try this:
self.popUpContainerView.alpha = 0;
[UIView animateWithDuration:0.1 animations:^{self.popUpContainerView.alpha = 1.0;}];
CAKeyframeAnimation *bounceAnimation = [CAKeyframeAnimation animationWithKeyPath:#"transform.scale"];
bounceAnimation.values = #[#0.01f, #1.1f, #1.0f];
bounceAnimation.keyTimes = #[#0.0f, #0.5f, #1.0f];
bounceAnimation.duration = 0.2;
[self.popUpContainerView.layer addAnimation:bounceAnimation forKey:#"bounce"];

Answer 4

Try these three methodes..
****vwTemp is my custome alert view****
- (void)showAlertView
{
vwTemp.transform = CGAffineTransformMakeScale( 0.001, 0.001);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/1.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(bounce1AnimationStopped)];
vwTemp.transform = CGAffineTransformMakeScale( 1.1, 1.1);
[UIView commitAnimations];
}
- (void)bounce1AnimationStopped
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/2];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(bounce2AnimationStopped)];
vwTemp.transform = CGAffineTransformMakeScale (0.9, 0.9);
[UIView commitAnimations];
}
- (void)bounce2AnimationStopped
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/2];
[UIView setAnimationDelegate:self];
vwTemp.transform = CGAffineTransformIdentity;
[UIView commitAnimations];
}

Answer 5

yourView.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.001, 0.001);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3/1.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(bounce1AnimationStopped)];
[self.view addSubview:yourView];
yourView.transform = CGAffineTransformScale(CGAffineTransformIdentity, 1.1, 1.1);
[UIView commitAnimations];
After bouncing animation two time this bellow two methods are used..
- (void)bounce1AnimationStopped {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3/2];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(bounce2AnimationStopped)];
yourView.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.9, 0.9);
[UIView commitAnimations];
}
- (void)bounce2AnimationStopped {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3/2];
yourView.transform = CGAffineTransformIdentity;
[UIView commitAnimations];
}

Use below code working in swift3
func popIn(yourView : UIView){
yourView.transform = CGAffineTransform(scaleX: 0.01, y: 0.01)
UIView.animateKeyframes(withDuration: 0.2, delay: 0.0, options: UIViewKeyframeAnimationOptions.calculationModeDiscrete, animations: {
yourView.transform = .identity
}, completion: nil)
}
func popOut(yourView: UIView) {
yourView.transform = .identity
UIView.animateKeyframes(withDuration: 0.2, delay: 0.0, options: UIViewKeyframeAnimationOptions.calculationModeDiscrete, animations: {
yourView.transform = CGAffineTransform(scaleX: 0.01, y: 0.01)
}, completion:{(_ finish : Bool) in
yourView.removeFromSuperview()}
)
}
