本文實(shí)例為大家分享了ios仿airpods彈出動(dòng)畫的具體代碼，供大家參考，具體內(nèi)容如下

思路
在當(dāng)前viewcontroller下present另外一個(gè)animationviewcontroller，在彈出的animationviewcontroller中播放動(dòng)畫，彈出的時(shí)候原來的viewcontroller上有一個(gè)全屏覆蓋的maskview，在彈出時(shí)，有一個(gè)漸變動(dòng)畫（頁面漸黑），在animationviewcontroller聲明一個(gè)代理，在代理方法中實(shí)現(xiàn)收起的動(dòng)畫效果（dissmisscontroller和maskview消失）

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]; }]; |
模態(tài)跳轉(zhuǎn)的style有一個(gè)枚舉值，在ios13以前modalpresentationstyle的默認(rèn)值為uimodalpresentationfullscreen,ios13以后變成了uimodalpresentationpagesheet,在這里我們把style設(shè)置為uimodalpresentationovercurrentcontext彈出的這個(gè)控制器就會(huì)覆蓋在原來的控制器之上

- (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;} |
一個(gè)覆蓋全屏的maskview采用懶加載的方式實(shí)現(xiàn)

動(dòng)畫這里用到的是lottie這個(gè)動(dòng)畫開源庫（airbnb），這個(gè)開源庫主要的功能是可以將after effects制作的動(dòng)畫通過插件導(dǎo)出為json格式的文件，然后通過這個(gè)開源庫解析成動(dòng)畫。

dissmiss當(dāng)前的控制器，讓viewcontroller來實(shí)現(xiàn)這個(gè)代理方法，并且在代理方法中隱藏maskview
