禁用窗口拉伸Cocoa？

func windowShouldZoom(_ sender: NSWindow, toFrame newFrame: NSRect) -> Bool {
    return false
}

- (BOOL)windowShouldZoom:(NSWindow *)window toFrame:(NSRect)newFrame {
    return NO;
}

func windowWillUseStandardFrame(_ window: NSWindow, defaultFrame: NSRect) -> NSRect {
    return defaultFrame
}

- (NSRect)windowWillUseStandardFrame:(NSWindow *)window defaultFrame:(NSRect)defaultFrame {
    return defaultFrame;
}
