本文介绍了一种在Unity中优化UI滚动面板的方法。通过临时禁用_itemGrid的keepWithinPanel属性，并重新定位ScrollView的位置，确保按钮在切换标签页时保持在正确位置，解决了因滚动条位置偏移导致的UI布局问题。

bool originalKeepWithinPanel = _itemGrid.keepWithinPanel;
_itemGrid.keepWithinPanel = false; //Need to set this to false or else buttons will not properly be at top if player scrolls past bottom then switch tabs

_scrollView.ResetPosition (); //Reset and move scroll panel back to original start position or else buttons keep shifting when changing tabs

_itemGrid.Reposition();
_scrollView.ResetPosition (); //Reset and move scroll panel back to original start position, required before and after tabbing - see ngui docs
_itemGrid.keepWithinPanel = originalKeepWithinPanel;
