oc 使用方式

//本地

    anview.speed = 1;
    anview.loopAnimationCount = 3;
    anview.frame = CGRectMake(50, 100, 200, 200);
    [self.view addSubview:anview];
}

//远层动画
- (void)remoteLottieAnm {
    FELottieView *aniView = [[FELottieView alloc] initWithRemoteUrl:@"https://assets3.lottiefiles.com/packages/lf20_17p4evft.json"];
    aniView.frame = CGRectMake(50, 400, 300, 300);
