ios - 动画内容插图

Question

我想为属于 UIWebView 的 scrollView 的 contentInset 设置动画。我尝试了下面的代码，但不幸的是 inset 在运行时只是跳转

UIViewAnimationOptions options = UIViewAnimationOptionBeginFromCurrentState;
[UIView animateWithDuration:10.0 delay:0 options:options animations:^
 {
     self.webView.scrollView.contentInset = UIEdgeInsetsMake(100 ,120,120,120);
 }
                 completion:nil];

有谁知道如何制作流畅的 contentInset 动画？我还尝试了 AllowAnimatedContent 选项，但没有成功

尝试这样的事情:

CGFloat height = 80.0f //change to whichever value you want

[UIView animateWithDuration:0.2 animations:^{
    [self.peopleCollectionView setContentInset:UIEdgeInsetsMake(height, 0, 0, 0)];
}];
[self.peopleCollectionView setContentOffset:CGPointMake(0, -height) animated:YES];
