cocoa - NSSplitView 和自动布局

Question

我应该如何在NSSplitView内使用自动布局约束 subview ？

我的NSSplitView subview 有 3 个 subview :topPane , tableContainer和bottomPane我这样设置约束:

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];

并在控制台中得到这个:

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]>

我认为<NSAutoresizingMaskLayoutConstraint:0x7fd6c3630430 h=--& v=--& V:[NSView:0x7fd6c4b22e50(0)]>导致此问题，但我无法重置自动调整大小蒙版，因为 NSSplitView设置它。

在分割 View 中使用自动布局的最佳方法是什么？有没有办法在没有NSSplitViewDelegate的情况下处理具有自动布局的分割 View subview 的最小/最大尺寸？

Answer 1

我发现如果我的窗口中有工具栏并通过任何此委托(delegate)方法控制分割 View ，则会出现此错误:

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

在 windowDidLoad 中将工具栏附加到窗口中找到了解决方案。
