ios - Strange UIView-Encapsulated-Layout-Height Error

Question

I'm making test application, so in my tableviewCell in storyboard I have imageView & webView (webview to show html-text).

I set constraints like top/left/right/height=200 for imageView, spacing=5 between them & left/right/bot for webView, so I want to calculate my webView height programmatically and then change cell's height to stretch my webView. But I got this :

Unable to simultaneously satisfy constraints.

Probably at least one of the constraints in the following list is one you don't want.

Try this:

    (1) look at each constraint and try to figure out which you don't expect;
    (2) find the code that added the unwanted constraint or constraints & fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property

    translatesAutoresizingMaskIntoConstraints) 
    (
        "<NSLayoutConstraint:0x7fd6f3773f90 V:[UIImageView:0x7fd6f3773e90(200)]>",
        "<NSLayoutConstraint:0x7fd6f3774280 UIImageView:0x7fd6f3773e90.top == UITableViewCellContentView:0x7fd6f3462710.topMargin>",
        "<NSLayoutConstraint:0x7fd6f3774320 V:[UIImageView:0x7fd6f3773e90]-(5)-[UIWebView:0x7fd6f3462800]>",
        "<NSLayoutConstraint:0x7fd6f3774370 UITableViewCellContentView:0x7fd6f3462710.bottomMargin == UIWebView:0x7fd6f3462800.bottom>",
        "<NSLayoutConstraint:0x7fd6f375ee40 'UIView-Encapsulated-Layout-Height' V:[UITableViewCellContentView:0x7fd6f3462710(205)]>"
    )

Any suggestions?

Answer 1

I usually remove this warning by lowering the priority of the constraint that AutoLayout is trying to break. So if it says:

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x7fd7c2ecb520 V:[UIView:0x7fd7c2ecd0e0(300)]>

Go ahead and lower that one's priority to 999.

That should work.

Cheers.
