以编程方式将NSScrollView滚动到左上角

Question

嗯，这就是我想要做的但到目前为止没有成功。

这就是我的尝试：

- (void)awakeFromNib
{
    [[_myScrollView contentView] scrollToPoint:NSMakePoint(0,[[_myScrollView contentView] bounds].size.height)];
}

有什么想法吗？

Answer 1

怎么样：

[[_myScrollView contentView] scrollToPoint:NSMakePoint(0,0)];

Answer 2

试试这个

NSPoint newScrollOrigin = NSMakePoint(0.0,NSMaxY([[_myScrollView documentView] frame])
                          -NSHeight([[_myScrollView contentView] bounds]));

[[_myScrollView documentView] scrollPoint:newScrollOrigin];
