必现/偶发? 必现

描述bug tableView 点击cell全屏播放视频，设置了无动画，但是dimiss时还是有向左上角坐标（0.0）的缩放动画

核心代码如下：

 SJPlayModel *playModel = [SJPlayModel  playModelWithTableView:self.tableView indexPath:indexPath];
  _player.URLAsset = [[SJVideoPlayerURLAsset alloc] initWithURL:url playModel:playModel];

@weakify(self);
[_player setFitOnScreen:YES animated:NO completionHandler:^(__kindof SJBaseVideoPlayer * _Nonnull player) {
    @strongify(self);
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        @strongify(self);
        [self.player play];
    });
}];

你期望的结果是什么? animated:NO 时,出现和消失都没有动画效果

发现是下面代码

• (void)_backButtonWasTapped { if ( self.isFullscreen && ![self _whetherToSupportOnlyOneOrientation] ) { [self rotate]; } else if ( self.isFitOnScreen ) { self.fitOnScreen = NO; } else { UIViewController *vc = [self.view lookupResponderForClass:UIViewController.class]; [vc.view endEditing:YES]; if ( vc.navigationController.viewControllers.count > 1 ) { [vc.navigationController popViewControllerAnimated:YES]; } else { vc.presentingViewController ? [vc dismissViewControllerAnimated:YES completion:nil] : [vc.navigationController popViewControllerAnimated:YES]; } } } 中 self.fitOnScreen = NO; 导致的

因为

• (void)setFitOnScreen:(BOOL)fitOnScreen { [self setFitOnScreen:fitOnScreen animated:YES]; } 始终会传YES，导致一直有动画效果，建议优化下
