NSScrollView滚动条怎么让它停在指定的位置或者点

Answer 1

以下代码应该可以的。
float ScrollLocation = 0.0;
float MaxScroll = 0.0;

[[m_textview enclosingScrollView] setLineScroll:0.0f];
[[m_textview enclosingScrollView] setPageScroll:0.0f];

ScrollLocation = [[[m_textview enclosingScrollView] contentView] bounds].origin.y;
MaxScroll = [[[m_textview enclosingScrollView] documentView] bounds].size.height - [[m_textview enclosingScrollView] documentVisibleRect].size.height;

ScrollLocation += 10;

if(ScrollLocation < 0)
{
ScrollLocation = 0;
}

else if(ScrollLocation >MaxScroll)
{
ScrollLocation = MaxScroll;
}
[m_textview scrollPoint:NSMakePoint(0, ScrollLocation)];
