Question

我想为属于UIWebView的scrollView的contentInset设置动画。我尝试了以下代码，但不幸的是，插件只是在运行时跳转

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

有谁知道如何制作一个平滑的contentInset动画？我也试过了没有运气的AllowAnimatedContent选项

Answer 1

尝试这样的事情：

[timeDict setObject:@"Hello" forKey:@"Greetings"];
    [timeDict setObject:@"Bye"   forKey:@"B_Key"];
    [timeDict setObject:@"what?" forKey:@"W_Key"];

    [[NSUserDefaults standardUserDefaults] setObject:timeDict forKey:@"Greetings"];
    [[NSUserDefaults standardUserDefaults] setObject:timeDict forKey:@"B_Key"];
    [[NSUserDefaults standardUserDefaults] setObject:timeDict forKey:@"W_Key"];
    [[NSUserDefaults standardUserDefaults] synchronize];


    timeDict = [[NSUserDefaults standardUserDefaults] objectForKey:@"Greetings"];
    timeDict = [[NSUserDefaults standardUserDefaults] objectForKey:@"B_Key"];
    timeDict = [[NSUserDefaults standardUserDefaults] objectForKey:@"W_Key"];

Swift 5.1?

UIView.animate({
     self.tableView.contentInset = .init(top: tableViewOffset, left: 0, bottom: 0, right: 0)
     self.tableView.setContentOffset(.init(x: 0, y: -tableViewOffset), animated: false)
  }, onComplete: { Swift.print("Anim completed") })

动画contentInset
