Question

如何以编程方式设置窗口大小？我在IB中有一个窗口，我想在我的代码中设置它的大小以使其更大。

Answer 1

使用-setFrame:display:animate:获得最大控制权：

NSRect frame = [window frame];
frame.size = theSizeYouWant;
[window setFrame: frame display: YES animate: whetherYouWantAnimation];

请注意，窗口坐标会从您可能习惯的位置翻转过来。矩形的原点位于OS X上Quartz / Cocoa的左下角。确保原点保持不变：

NSRect frame = [window frame];
frame.origin.y -= frame.size.height; // remove the old height
frame.origin.y += theSizeYouWant.height; // add the new height
frame.size = theSizeYouWant;
// continue as before

Answer 2

实际上似乎需要反转+/-以防止窗口在屏幕上移动：

NSRect frame = [window frame];
frame.origin.y += frame.size.height; // origin.y is top Y coordinate now
frame.origin.y -= theSizeYouWant.height; // new Y coordinate for the origin
frame.size = theSizeYouWant;

Answer 3

Swift版

var frame = self.view.window?.frame
frame?.size = NSSize(width: 400, height:200)
self.view.window?.setFrame(frame!, display: true)

Answer 4

使用setFrame:display:animate:

[window setFrame:NSMakeRect(0.f, 0.f, 200.f, 200.f) display:YES animate:YES];

Answer 5

通常，我想根据内容的大小（不包括标题栏）来调整窗口的大小：

var rect = window.contentRect(forFrameRect: window.frame)
rect.size = myKnownContentSize
let frame = window.frameRect(forContentRect: rect)
window.setFrame(frame, display: true, animate: true)
