How to move UIImageView while swiping in UIPageViewContoller - ios

Question

I would like to move red circle (as shown in following image) slowly (may be with animation) when user swipes the app intro (PageViewController). I also want to add some animations so I'm trying to use IFTTT/JazzHands framework. But it's difficult for me to understand currently. Is there any easy way to use animation in PageViewController? Or are there any tutorials that uses IFTTT/JazzHands framework? Could anybody help me, please?

Try this if its is ok vote for me
#interface homeViewController ()<UIScrollViewDelegate>
#property (weak, nonatomic) IBOutlet UIScrollView *scrollViewSlider;
#end
#implementation homeViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.navigationController.navigationBarHidden=true;
[NSTimer scheduledTimerWithTimeInterval:4 target:self
selector:#selector(scrollingTimer) userInfo:nil repeats:YES];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
/*
#pragma mark - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
// Get the new view controller using [segue destinationViewController].
// Pass the selected object to the new view controller.
}
*/
-(void)viewDidLayoutSubviews
{
UIImage *imageOne = [UIImage imageNamed:#"download.jpeg"];
UIImage *imageTwo = [UIImage imageNamed:#"download2.jpeg"];
UIImage *imageThree = [UIImage imageNamed:#"download3.jpeg"];
UIImage *imageFour = [UIImage imageNamed:#"download4.jpeg"];
NSArray *imageArray = [NSArray arrayWithObjects:imageOne,
imageTwo, imageThree, imageFour, nil];
for (int i = 0; i <= 3; i++) {
UIImageView *imgView = [[UIImageView alloc]init];
imgView.contentMode = UIViewContentModeScaleToFill;
imgView.alpha = 0.5f;
imgView.frame = CGRectMake(i * self.scrollViewSlider.bounds.size.width,
0, self.scrollViewSlider.bounds.size.width,
self.scrollViewSlider.bounds.size.height);
[imgView setImage:imageArray[i]];
[self.scrollViewSlider addSubview:imgView];
self.scrollViewSlider.pagingEnabled = true;
[self.scrollViewSlider setContentSize:CGSizeMake(imageArray.count *
self.scrollViewSlider.bounds.size.width,
self.scrollViewSlider.bounds.size.height-20)];
}
}
-(void) scrollingTimer
{
CGPoint frame = self.scrollViewSlider.contentOffset;
[UIView animateWithDuration:3.0f animations:^(void) {
if (frame.x != 3 * self.scrollViewSlider.frame.size.width)
[self.scrollViewSlider setContentOffset:CGPointMake(frame.x +
self.scrollViewSlider.frame.size.width, 0)];
else
[self.scrollViewSlider setContentOffset:CGPointMake(0, 0)];
}];
}

Try this code without any Third party Class
just add QuartzCore framwork from library
#import <QuartzCore/QuartzCore.h>
- (CAAnimation*)movedown;
{
CABasicAnimation *animation = [CABasicAnimation animation];
animation.keyPath = #"position.y";
animation.fromValue = #600;
animation.toValue = #50;
animation.duration = 0.25;
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
[subView.layer addAnimation:animation forKey:#"basic"];
subView.layer.position = CGPointMake(0,-20);
return animation;
}
pls replace your animation view in-place of subview.
