NSSplitView和自动布局

问题描述

我应该如何使用自动布局内 NSSplitView 子视图？

How should I use auto layout constrains inside NSSplitView subview?

我的 NSSplitView 子视图有3子视图： topPane ， tableContainer 和 bottomPane 和我这样设置约束：

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];

和控制台得到这个：

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]>

我觉得＆LT; NSAutoresizingMaskLayoutConstraint：0x7fd6c3630430 H = - ＆安培; V = - ＆安培;五：[的NSView：0x7fd6c4b22e50（0）。＆GT; 导致此，但我不能复位自动调整面膜，因为 NSSplitView 设置为

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

什么是使用拆分视图内的自动布局最好的方法？而有什么办法没有 NSSplitViewDelegate ？

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?

推荐答案

我发现，如果我有出现这个错误的工具栏在任何的这个委托方法我的窗口和控制拆分视图：

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:

解决方案是在windowDidLoad附加工具栏窗口中。

Solution was found in attaching toolbar to window in windowDidLoad.
