How to set the content size of NSScrollView?
提问by Developer
I am new to Mac OSX Programming. I have created on iOS apps in which I can set The content size of UISCrollView by using contentSize property. But there is no such property I found for Mac Apps. How it can be done and how can I enable the scrolling in Mac App. I looked on to the other questions on Stackoverflow but I didn't find anything relevant. Thanks-
我是 Mac OSX 编程的新手。我在 iOS 应用程序上创建了，我可以在其中使用 contentSize 属性设置 UISCrollView 的内容大小。但是我没有为 Mac Apps 找到这样的属性。如何完成以及如何在 Mac App 中启用滚动。我查看了 Stackoverflow 上的其他问题，但没有找到任何相关内容。谢谢-

NSScrollView has documentView attached to it. You can change the content size by updating the frame of documentView.
NSScrollView 附加了 documentView。您可以通过更新 documentView 的框架来更改内容大小。
[scrollView.documentView setFrame: NSMakeRect(0,0,new_width, new_height) ];
[scrollView.documentView setFrame: NSMakeRect(0,0,new_width, new_height) ];
