NSScrollView 如何从左上角开始 [英] NSScrollView how to start from top left corner

问题描述

如何设置scrollView文档视图固定在左上角?如果 scrollView 足够大/大于其内容，则所有内容都是从下到上绘制的，看起来不正确.我必须覆盖 scrollView 的 isFlipped?

How to set scrollView document view to be pinned to top left corner? If scrollView is big enough/bigger than its content, everything is drawn from bottom to up and it not looks right. I have to override isFlipped of scrollView?

我在互联网上搜索并覆盖 isFlipped 以返回 true 并不是万能的.我不想让我的 documentView 翻转，因为那样我必须在那个类中进行更改以使一切看起来像我想要的.

I was searching internet and overriding isFlipped to return trueis not everything. I don't want to make my documentView flipped because then I have to make changes in that class to make everything looks like I want.

@interface FlippedView : NSView

@end

和实施:

@implementation FlippedView

- (void)drawRect:(NSRect)dirtyRect {
    [super drawRect:dirtyRect];

    // Drawing code here.
}

- (BOOL) isFlipped
{
    return YES;
}

@end
