Here in my app i used the moving sub View.If it reach y=150,i want to make a buttons in jumping effect,i tried this link adding bounce effect to appearance of UIImageView it working in horizontal direction ,i want a vertical direction,Here my code,
-(void)godown
{
if (movingview.center.y < 150) movingview.center = CGPointMake(movingview.center.x, movingview.center.y +5);
if(movingview.center.y ==150)
{
[UIView beginAnimations:@"bounce" context:nil];
[UIView setAnimationRepeatCount:3];
[UIView setAnimationRepeatAutoreverses:YES];
CGAffineTransform transform = CGAffineTransformMakeScale(1.3,1.3);
bt1.transform = transform;
bt2.transform=transform;
[UIView commitAnimations];
}
}
Please help me to change into jumping effect(vertically)?
Try this. You can make some changes so it suits your need,
CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"transform"];
anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
anim.duration = 0.125;
anim.repeatCount = 1;
anim.autoreverses = YES;
anim.removedOnCompletion = YES;
anim.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeScale(1.2, 1.2, 1.0)];
[senderView.layer addAnimation:anim forKey:nil];
Hope this helps.
