addSubview和autosizing

Question

如何为窗口添加视图,以便调整视图大小以适应窗口框架？

问题

我正在制作一个包含2个视图的工作表窗口,其中一次只能看到其中一个视图,因此视图与窗口大小相同非常重要.我的问题是view0正确匹配而view1没有,反之亦然.我无法弄清楚如何给它们与窗口相同的大小.

可能解决方案

我可以确保两个视图在Interface Builder中具有完全相同的大小,然后它就可以工作了.但是,我正在寻找一种以编程方式执行此操作的方法.

view0的屏幕截图

下面您可以看到顶部和右侧的自动调整问题,其中视图以某种方式被剪切.

view1的屏幕截图

此视图已正确调整大小.

这是我的代码

可以在将视图添加到窗口之前调整视图的大小.或者我现在做的更好,在改变窗口框架的同时逐个添加视图.你怎么做呢？

NSView* view0 = /* a view made with IB */;
NSView* view1 = /* another view made with IB */;
NSWindow* window = [self window];

NSRect window_frame = [window frame];

NSView* cv = [[[NSView alloc] initWithFrame:window_frame] autorelease];
[window setContentView:cv];
[cv setAutoresizesSubviews:YES];

// add subview so it fits within the contentview frame
{
    NSView* v = view0;
    [v setHidden:YES];
    [v setAutoresizesSubviews:NO];
    [cv addSubview:v];
    [v setFrameOrigin:NSZeroPoint];
    [window setFrame:[v frame] display:NO];
    [v setAutoresizesSubviews:YES];
}

// add subview so it fits within the contentview frame
{
    NSView* v = view1;
    [v setHidden:YES];
    [v setAutoresizesSubviews:NO];
    [cv addSubview:v];
    [v setFrameOrigin:NSZeroPoint];
    [window setFrame:[v frame] display:NO];
    [v setAutoresizesSubviews:YES];
}

// restore original window frame
[window setFrame:window_frame display:YES];

[view0 setHidden:NO];
[view1 setHidden:YES];

解决了!我在stackoverflow上找到了一个解决方案.

如果这个代码可以缩短,那将会很好.

NSView* view0 = /* a view made with IB */;
NSView* view1 = /* another view made with IB */;
NSWindow* window = [self window];

NSRect window_frame = [window frame];

NSView* cv = [[[NSView alloc] initWithFrame:window_frame] autorelease];
[window setContentView:cv];
[cv setAutoresizesSubviews:YES];

// add subview so it fits within the contentview frame
{
    NSView* v = view0;
    NSRect vframe = [v frame];
    [v setHidden:YES];
    [v setAutoresizingMask:NSViewWidthSizable | NSViewHeightSizable];

    NSView* tmp_superview = [[[NSView alloc] initWithFrame:vframe] autorelease];
    [tmp_superview addSubview:v];
    [tmp_superview setAutoresizesSubviews:YES];
    [tmp_superview setFrame:window_frame];

    [v removeFromSuperview];
       [cv addSubview:v];
}

// add subview so it fits within the contentview frame
{
    NSView* v = view1;
    NSRect vframe = [v frame];
    [v setHidden:YES];
    [v setAutoresizingMask:NSViewWidthSizable | NSViewHeightSizable];

    NSView* tmp_superview = [[[NSView alloc] initWithFrame:vframe] autorelease];
    [tmp_superview addSubview:v];
    [tmp_superview setAutoresizesSubviews:YES];
    [tmp_superview setFrame:window_frame];

    [v removeFromSuperview];
    [cv addSubview:v];
}

[view0 setHidden:NO];
