异常分析

APP crash在

1
[keyWindow addSubview:weakSelf];

错误堆栈信息。

但是真正造成crash的代码为：

1
[self.layer insertSublayer:xxxView.layer atIndex:0];

解决方案：

1
2
[self layoutIfNeeded];
[self.layer insertSublayer:xxxView.layer atIndex:0];

原因分析：
下面这个说的很在理

I had this issue with a library when moving over to Xcode 8 (Material-Controls-For-iOS - MDTextField). I found that the problem was coming from where the layer of one view (which had no superview) was being added to another.

It looks like this may be the case for yourself also - your toolbar being created has not been added to a superview first. The fix I used was to add the view as a subview of the view that the layer was being added to, so in your case adding the toolbar as a subview of myModelView should stop the error.
