NSSplitView and autolayout

Question

How should I use auto layout constrains inside NSSplitView subview?

My NSSplitView subview has 3 subview: topPane, tableContainer and bottomPane and I set the constrains like this:

NSDictionary* views = NSDictionaryOfVariableBindings(topPane, tableContainer, bottomPane);

for (NSView* view in [views allValues]) {
    [view setTranslatesAutoresizingMaskIntoConstraints:NO];
}

[myView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[topPane(34)][tableContainer][bottomPane(24)]|"
                                                               options:0 
                                                               metrics:nil 
                                                                 views:views]];

[mySplitView addSubview:myView];

And got this in console:

Unable to simultaneously satisfy constraints:
(
    "<NSLayoutConstraint:0x7fd6c4b1f770 V:[NSScrollView:0x7fd6c4b234c0]-(0)-[CPane:0x7fd6c4b2fd10]>",
    "<NSLayoutConstraint:0x7fd6c4b30910 V:[CPane:0x7fd6c4b2f870(34)]>",
    "<NSLayoutConstraint:0x7fd6c4b30770 V:|-(0)-[CPane:0x7fd6c4b2f870]   (Names: '|':NSView:0x7fd6c4b22e50 )>",
    "<NSLayoutConstraint:0x7fd6c4b212f0 V:[CPane:0x7fd6c4b2fd10]-(0)-|   (Names: '|':NSView:0x7fd6c4b22e50 )>",
    "<NSLayoutConstraint:0x7fd6c4b2f910 V:[CPane:0x7fd6c4b2f870]-(0)-[NSScrollView:0x7fd6c4b234c0]>",
    "<NSLayoutConstraint:0x7fd6c4b21290 V:[CPane:0x7fd6c4b2fd10(24)]>",
    "<NSAutoresizingMaskLayoutConstraint:0x7fd6c3630430 h=--& v=--& V:[NSView:0x7fd6c4b22e50(0)]>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x7fd6c4b1f770 V:[NSScrollView:0x7fd6c4b234c0]-(0)-[CPane:0x7fd6c4b2fd10]>

I think <NSAutoresizingMaskLayoutConstraint:0x7fd6c3630430 h=--& v=--& V:[NSView:0x7fd6c4b22e50(0)]> causes this, but I can't reset autoresizing mask, because NSSplitView sets it.

What is best way to use auto layout inside split view? And is there any way to handle min/max size of split view subview with auto layout without NSSplitViewDelegate?

Answer 1

I found out that this error appears if I have toolbar in my window and control split view by any of this delegate methods:

splitView:constrainMinCoordinate:ofSubviewAt:   
splitView:constrainMaxCoordinate:ofSubviewAt:
splitView:shouldAdjustSizeOfSubview:

Solution was found in attaching toolbar to window in windowDidLoad.
