Constraints strangely breaking about masonry HOT 3 CLOSED

Hey so I narrowed down what was causing the constraints on my custom toolbar to break. I'm not sure if this is a bug or not, but it ended up coming from constraints I had applied to UILabels.

I'll try my best to explain.

My UIViewController hierarchy looks like below where rootView is the view of my UIViewController. That view has 3 subviews. Navigation Bar, Toolbar, and a Modal. All of these are custom classes I created which have a root view attached to the UIViewController like you see below.

rootView
-> navigation bar (Custom UIView)
-> title(UILabel)
-> toolbar (Custom UIView)
-> button 0 (UIButton)
-> button 1 (UIButton)
-> button 2 (UIButton)
-> button 3 (UIButton)
-> modal(Custom UIView)
-> optionsView (UIView)
-> title(UILabel)

The UILabel titles that are attached to those view's had top, left, right, and height constraints like this which was causing the button width constraints to break on my toolbar when ever I either dismissed a view controller or rotated the device.

make.top.equalTo(self.view.mas_top).with.offset(statusBarHeight);
make.left.equalTo(self.view.mas_left);
make.right.equalTo(self.view.mas_right);
make.height.equalTo([NSNumber numberWithFloat:titleHeight]);

Changing the UILabel constraints to what I have now below has fixed the toolbar constraints from breaking. I'm not entirely sure how this fixed it, but it did. These are the only UILabels I have constraints applied to and I had to change both because it kept breaking the toolbar button constraints.

make.top.equalTo(self.view.mas_top).with.offset(statusBarHeight);
make.centerX.equalTo(self.view.mas_centerX);
make.width.equalTo([NSNumber numberWithFloat:titleWidth]);
make.height.equalTo([NSNumber numberWithFloat:titleHeight]);

Sorry for the late reply, I'm currently traveling and am in and out of wifi. UILabels are a bit of a special case in auto layout. You may need to set preferredMaxLayoutWidth see the labels example.

Also just a tip to make your code a bit more concise. You can do @(titleWidth) instead of [NSNumber numberWithFloat:titleWidth]

Hey good to know it's definitely UILabels. Thanks for the tip too and great work on Masonry.
