我有一个 ViewController 调用另一个视图，该视图包含 a contentView，然后是webView顶部的 a 。我正在尝试在顶部添加按钮，webView并试图让它们使用自动调整大小遮罩大约两个小时，但没有成功。当我尝试在旋转时重置框架时，按钮需要几分钟才能重新定位，因此看起来很滞后。这是我init的视图方法：

self = [super initWithFrame:frame];
    if (self) {
        _contentView = [[UIView alloc] initWithFrame:frame];
        _contentView.backgroundColor = [UIColor whiteColor];
        _contentView.clipsToBounds = YES;
        self.clipsToBounds = YES;

        UIImage *facebookShare = [UIImage imageNamed:@"share_facebook_focus_pad"];
        self.facebookButton = [[UIButton alloc] initWithFrame:CGRectMake(700, 150, facebookShare.size.width, facebookShare.size.height)];
        //[facebookButton setAutoresizingMask:UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleBottomMargin];
        [self.facebookButton setImage:facebookShare forState:UIControlStateNormal];
        [_webView addSubview:self.facebookButton];

        UIImage *twitterShare = [UIImage imageNamed:@"share_twitter_focus_pad"];
        self.twitterButton = [[UIButton alloc] initWithFrame:CGRectMake(self.facebookButton.frame.origin.x, self.facebookButton.frame.origin.y + facebookShare.size.height, twitterShare.size.width, twitterShare.size.height)];
        //twitterButton.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        [self.twitterButton setImage:twitterShare forState:UIControlStateNormal];
        [_webView addSubview:self.twitterButton];

        UIImage *mailShare = [UIImage imageNamed:@"share_mail_focus_pad"];
        self.mailButton = [[UIButton alloc] initWithFrame:CGRectMake(self.facebookButton.frame.origin.x, self.facebookButton.frame.origin.y + facebookShare.size.height + twitterShare.size.height, mailShare.size.width, mailShare.size.height)];
        //mailButton.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        [self.mailButton setImage:mailShare forState:UIControlStateNormal];
        [_webView addSubview:self.mailButton];

        [_contentView addSubview:_webView];
        [self addSubview:_contentView];

        self.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        self.contentView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        self.webView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        self.webView.frame = CGRectMake(CGRectGetMinX(self.frame), CGRectGetMinY(self.frame), CGRectGetWidth(self.frame), CGRectGetHeight(self.frame));

    }

只需在_webView. 我试图将它们放在右上角，因此，我需要屏蔽left和bottom. 在这里，我注释掉了 twitter 和邮件按钮，并使用 Facebook 按钮对其进行了测试。我专门将 Facebook 按钮设置为 x 坐标 700 - 但是一旦我取消注释自动调整大小蒙版线，如上所示，Facebook 按钮就会消失！！这是怎么发生的？除非已旋转，否则自动调整蒙版不会与 x 坐标一起使用！尽管如此，它应该很好地对齐它并将它推到右上角，因为我掩盖了左下角。这是怎么回事？这非常令人沮丧 - 我已经与它战斗了大约 2 个小时！

PS：我没有使用界面生成器。请不要建议我使用它。

尝试

self.facebookButton.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

并首先设置 webview 的框架，然后添加按钮，然后尝试更改方向。
