Animate button two Labels Text change - ios

Question

Here the issue is , when i was tap the button the two labels text will be change,but i'm not able to display that animated function here the my code,
CABasicAnimation *rotate =
[CABasicAnimation animationWithKeyPath:#"transform.rotation"];
rotate.byValue = #(M_PI*1); // Change to - angle for counter clockwise rotation
rotate.duration = 0.4;
[_button.layer addAnimation:rotate
forKey:#"myRotationAnimation"];
CATransition *animation = [CATransition animation];
animation.duration = 1.0;
animation.type = kCATransitionFromBottom;
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
[_name1.layer addAnimation:animation forKey:#"changeTextTransition"];
[_name2.layer addAnimation:animation forKey:#"changeTextTransition"];
// Change the text
_from.text = #"new 222text";
_to.text = #"new text";
but i want change like this,
When i tapped that arrow button ,from and to address will be change up and down animation.Can you please help me ,i'm trying but i can not figure out like that,Thank you.

Answer 1

Try this code to animate your label:
- (CAAnimation*)moveup;
{
CABasicAnimation *animation = [CABasicAnimation animation];
animation.keyPath = #"position.y";
animation.fromValue = #-500;
animation.toValue = #10;
animation.duration = 0.25;
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
[label1.layer addAnimation:animation forKey:#"basic"];
[label2.layer addAnimation:animation forKey:#"basic"];
label1.layer.position = CGPointMake(0,20);
label2.layer.position = CGPointMake(0,20);
return animation;
}
and add the dimention parameter according to your need.
hope this will work fine.
you can rotate through this code:
-(CAAnimation*)rotate
{
CGRect boundingRect = CGRectMake(350, -500, -5,-5);
CAKeyframeAnimation *orbit = [CAKeyframeAnimation animation];
orbit.keyPath = #"position";
orbit.path = CFAutorelease(CGPathCreateWithEllipseInRect(boundingRect, NULL));
orbit.duration =0.5;
orbit.additive = YES;
orbit.repeatCount = HUGE_VALF;
orbit.calculationMode = kCAAnimationPaced;
orbit.rotationMode = kCAAnimationRotateAuto;
[btnScan.layer addAnimation:orbit forKey:#"orbit"];
return orbit;
}

Answer 2

I found a method for text change for the labels while button action,
bool isShown = false;
In the button Action :
- (IBAction)textChange:(id)sender {
if (!isShown) {
from.frame = CGRectMake(31, 220, 217 , 38);
to.frame = CGRectMake(31, 275, 217 , 38);
[UIView animateWithDuration:0.25 animations:^{
from.frame = CGRectMake(31, 275, 217, 38);
to.frame = CGRectMake(31, 220, 217 , 38);
}];
isShown = true;
} else {
[UIView animateWithDuration:0.25 animations:^{
from.frame = CGRectMake(31, 220, 217, 38);
to.frame = CGRectMake(31, 275, 217, 38);
}];
isShown = false;
}
}
Thank you.
