在我的 iOS 应用程序中，我有一些动画似乎不知从何而来。它们一开始不会发生，只有在稍微使用该应用程序后才会发生。这是一个有更好描述的 Youtube 视频：

我不太确定为什么这些元素会以它们（或根本）的方式进行动画处理。我调用的代码只是一个简单的 [view addSubView:viewname]。关于这种情况如何发生以及如何防止它的任何帮助都会很棒。

编辑 这是从看似四面八方飞来的文本的代码：

-(void)displayPublicDataForEntry:(PFObject *)entry likes:(unsigned long)likesCount comments:(unsigned long)commentsCount
{
    [indicator stopAnimating];
    [indicator removeFromSuperview];
    [zippingLabel removeFromSuperview];

    entryStatus.text = @"This entry is public";
    entryStatus.backgroundColor = [UIColor clearColor];
    entryStatus.frame = CGRectMake(10, 3, 200, 20);
    [shareView addSubview:entryStatus];

    // Display a UILabel of number of likes
    if (likesCount == 1)
        numberOfLikes.text = [NSString stringWithFormat:@"%lu like", likesCount];
    else
        numberOfLikes.text = [NSString stringWithFormat:@"%lu likes", likesCount];

    CGSize stringsize = [numberOfLikes.text sizeWithFont:[UIFont systemFontOfSize:14]];

    numberOfLikes.frame = CGRectMake(10, 22, stringsize.width, 20);
    numberOfLikes.backgroundColor = [UIColor clearColor];
    [shareView addSubview:numberOfLikes];

    // Display a UILabel of number of comments
    if (commentsCount == 1)
        numberOfComments.text = [NSString stringWithFormat:@" / %lu comment", commentsCount];
    else
        numberOfComments.text = [NSString stringWithFormat:@" / %lu comments", commentsCount];

    numberOfComments.frame = CGRectMake(numberOfLikes.frame.size.width + 10, 22, 100, 20);
    numberOfComments.backgroundColor = [UIColor clearColor];
    [shareView addSubview:numberOfComments];

    viewEntry.frame = CGRectMake(self.view.frame.size.width - 95, 12, 100, 40);
    [viewEntry addTarget:self
                  action:@selector(viewPublicEntry)
        forControlEvents:UIControlEventTouchUpInside];
    [shareView addSubview:viewEntry];
}

那里没有任何东西（至少我认为没有）会导致这些奇怪的动画。

我有这个问题。原因最终是调用开始动画而没有调用提交。我以某种方式调用了 [UIView beginAnimations:Nil context:nil] 两次。
