应用错误收集

我使用代码创建了一个UIScrollView，我创建了子视图，我从DB中动态创建了添加到视图数组和UIScrollviews的子视图。我正在使用touchesBegan和touchesMoved方法。我选择的子视图是不被识别的，但是控件进入touchesBegan并触及移动的方法。我已经发布了下面的代码。请任何人帮助我克服这个问题。

我已经通过代码创建了scrollview，并且我在名为“arrayofviews”的数组中有子视图。这些子视图与数组中的视图相同。我能够在普通视图中移动这些来自数据库的子视图，但是当我将这些视图添加到scrollview时它无法正常工作。

我已经尝试了很多网络中的解决方案，但我无法得到合适的解决方案。
