Iphone 在不更新滚动手柄的情况下更新UIScrollView的子视图

好的，我有一个子类的UIScrollView，里面有一些子视图，当设备方向改变时，我想更新里面子视图的位置，使它们适合新的方向

当我刚刚更新子视图的位置，然后去滚动时，我注意到滚动手柄是巨大的。。。我的循环遍历了所有子视图并更新了它们的帧，同时也设置了滚动手柄的帧

所以为了避开这件事。。每当我添加子视图时，我都会在它们上设置一个标记。当方向改变时，我的设置框架周围有一个条件，检查视图上的标记是否与我添加的子视图匹配。如果是，则设置帧

int i = 0;

for (UIView *gridViewItem in self.subviews) {

    if (gridViewItem.tag == GRID_CELL) {
        gridViewItem.frame = [self calculateCellPosition:i];
    }

    i++;

}

但是现在我想检测子视图上的触摸，我能想到的最简单的方法是使用tag属性，这样我就知道正在点击哪个子视图。。。但是，该标记当前用于帮助我区分滚动手柄与其他子视图

当我注销UIScrollView的子视图时，我得到了以下信息：

所有子视图上都有我的标记！我看不到滚动手柄？有人知道一种不用像我这样的标签就能识别滚动手柄的方法吗

---

非常感谢您的帮助！谢谢

我可能不会为此将UIScrollView分为子类。将单个UIView添加到UIScrollView，并将单元格添加到该视图。然后始终使用该视图。不需要标记，并且不会干扰UIScrollViews内部工作。只要内容视图的大小反映其中的单元格，滚动就可以工作。

哦，好的，这很有意义。我会试试的，非常感谢！
