Question

我有一个自定义的UIScrollView，我添加了5个imageView作为其子视图。但是，在我记录它的子视图数组后，它有6个孩子！我使用storyboard添加scrollview添加拖动它的IBOutlet。我不知道firstObject来自哪里？

double Funkcija(double x){
    double result = -1/(1+abs(x));
    return result;
}

UIScrollView有两个默认的UIImageView来显示你的滚动条。您可能启用了水平/垂直滚动指示器，这就是您看到这个额外的UIImageView子项的原因。

我的自定义UIScrollview的第一个对象是什么？
