iOS rebound animation effect

Create a new item, and then put a view in the storyboard and set the view position in AutoLayout

And the top of the distance (set Y)

Distance from left (set X)

Set size

Drag a port for view

Add a drag gesture to the view in Viewdidload

-(void) viewdidload {
    [super viewdidload];
    Add drag gesture
    uipangesturerecognizer *pan = [[Uipangesturerecognizer alloc] 	initwithtarget:self action: @selector (Handlepan:)];
    [Self.springbackview Addgesturerecognizer:pan];
    Do no additional setup after loading the view, typically from a nib.
}

Next, implement Handlepan:

-(void) Handlepan: (uipangesturerecognizer*) recognizer{
    
    cgpoint translation = [recognizer Translationinview: Self.view];
    Recognizer.view.center = Cgpointmake (recognizer.view.center.x + translation.x,
                                         recognizer.view.center.y + TRANSLATION.Y);
    [Recognizer Settranslation:cgpointzero InView:self.view];
    
    if (recognizer.state = = uigesturerecognizerstateended) {
    
        [UIView animatewithduration:0.3 delay:0 usingspringwithdamping:0.5 initialspringvelocity:10 options:0 animations:^{
            [Self.springbackview Layoutifneeded];
    } Completion:nil];
        
    }

OK, now run your program to drag the view ...
