iOS仿AirPods弹出动画

思路

在当前viewcontroller下present另外一个animationviewcontroller,在弹出的animationviewcontroller中播放动画,弹出的时候原来的viewcontroller上有一个全屏覆盖的maskview,在弹出时,有一个渐变动画(页面渐黑),在animationviewcontroller声明一个代理,在代理方法中实现收起的动画效果(dissmisscontroller和maskview消失)

主要代码

hcairpodsanimationviewcontroller *vc = [[hcairpodsanimationviewcontroller alloc] init];
  vc.delegate = self;
  vc.modalpresentationstyle = uimodalpresentationovercurrentcontext;
  
  [uiview animatewithduration:0.2 animations:^{
    self.maskbgview.alpha = 0.5;
  } completion:nil];
  
  [self presentviewcontroller:vc animated:yes completion:^{
    [vc.animationview play];
  }];

模态跳转的style有一个枚举值,在ios13以前modalpresentationstyle的默认值为uimodalpresentationfullscreen,ios13以后变成了uimodalpresentationpagesheet,在这里我们把style设置为uimodalpresentationovercurrentcontext弹出的这个控制器就会覆盖在原来的控制器之上

- (uiview *)maskbgview
{
  if (!_maskbgview) {
    _maskbgview = [[uiview alloc] initwithframe:cgrectmake(0, 0, [uiscreen mainscreen].bounds.size.width, [uiscreen mainscreen].bounds.size.height)];
    _maskbgview.backgroundcolor = [uicolor blackcolor];
    _maskbgview.alpha = 0;
    [self.view addsubview:_maskbgview];
  }
  return _maskbgview;
}

一个覆盖全屏的maskview采用懒加载的方式实现

- (void)initcontentview
{
  cgfloat containerw = screen_width - 20;
  cgfloat containerh = containerw * 0.9;
  uiview *containerview = [[uiview alloc] initwithframe:cgrectmake(10, screen_height - containerh - 10, containerw, containerh)];
  containerview.layer.cornerradius = 20;
  containerview.backgroundcolor = [uicolor whitecolor];
  [self.view addsubview:containerview];
  
  self.animationview = [[lotanimationview alloc] initwithframe:cgrectmake(70, 70, containerw - 140, containerh - 140)];
  [containerview addsubview:self.animationview];
  self.animationview.animation = @"gift_animation";
  
  self.animationview.loopanimation = yes;
  
  uibutton *confirmbutton = [[uibutton alloc] initwithframe:cgrectmake(0, 0, 200, 34)];
  confirmbutton.center = cgpointmake(self.animationview.center.x, containerh - 44);
  
  [confirmbutton settitle:@"close" forstate:uicontrolstatenormal];
  [confirmbutton settitlecolor:[uicolor whitecolor] forstate:uicontrolstatenormal];
  
  [confirmbutton setbackgroundcolor:[uicolor bluecolor]];
  confirmbutton.layer.cornerradius = 10;
  
  [confirmbutton addtarget:self action:@selector(onconfirmbuttonclick) forcontrolevents:uicontroleventtouchupinside];
  [containerview addsubview:confirmbutton];
}

动画这里用到的是lottie这个动画开源库(airbnb),这个开源库主要的功能是可以将after effects制作的动画通过插件导出为json格式的文件,然后通过这个开源库解析成动画。

- (void)onconfirmbuttonclick
{
  if ([self.delegate respondstoselector:@selector(onairpodsanimationviewcontrollerconfirmbuttonclick:)]) {
    [self dismissviewcontrolleranimated:yes completion:nil];
    [self.delegate onairpodsanimationviewcontrollerconfirmbuttonclick:self];
  }
}

dissmiss当前的控制器,让viewcontroller来实现这个代理方法,并且在代理方法中隐藏maskview

}
