      Description

      I am facing a problem with the iOS version of my project since I updated my cordova-ios version to 4.5.4 (and now with 4.6.0).

      It happens anytime I click on an input element and the keyboard gets displayed. There is a constraint error that did not appear before and I don't know from where it comes from:

      [LayoutConstraints] 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 and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) (     "<NSAutoresizingMaskLayoutConstraint:0x1c02995f0 h=-&- v=-&- _UIToolbarContentView:0x1035988e0.width == UIToolbar:0x103598690.width   (active)>",     "<NSLayoutConstraint:0x1c4282df0 H:|-(0)-[_UIButtonBarStackView:0x103652760]   (active, names: '|':_UIToolbarContentView:0x1035988e0 )>",     "<NSLayoutConstraint:0x1c4282d50 _UIButtonBarStackView:0x103652760.trailing == _UIToolbarContentView:0x1035988e0.trailing + 8   (active)>",     "<NSLayoutConstraint:0x1c428a910 H:|-(0)-[_UIModernBarButton:0x10366eaf0]   (active, names: '|':_UIButtonBarButton:0x10366e4a0 )>",     "<NSLayoutConstraint:0x1c428a960 H:[_UIModernBarButton:0x10366eaf0]-(>=8)-|   (active, names: '|':_UIButtonBarButton:0x10366e4a0 )>",     "<NSLayoutConstraint:0x1c428af50 H:|-(>=5)-[_UIModernBarButton:0x10366f560]   (active, names: '|':_UIButtonBarButton:0x10366f310 )>",     "<NSLayoutConstraint:0x1c428afa0 H:[_UIModernBarButton:0x10366f560]-(>=5)-|   (active, names: '|':_UIButtonBarButton:0x10366f310 )>",     "<NSLayoutConstraint:0x1c428b900 H:|-(8)-[_UIModernBarButton:0x10366fce0'Done']   (active, names: '|':_UIButtonBarButton:0x10366fa90 )>",     "<NSLayoutConstraint:0x1c428b950 H:[_UIModernBarButton:0x10366fce0'Done']-(0)-|   (active, names: '|':_UIButtonBarButton:0x10366fa90 )>",     "<NSLayoutConstraint:0x1c0298010 'UISV-canvas-connection' UILayoutGuide:0x1c41bdea0'UIViewLayoutMarginsGuide'.leading == _UIButtonBarButton:0x10366e4a0.leading   (active)>",     "<NSLayoutConstraint:0x1c0298060 'UISV-canvas-connection' UILayoutGuide:0x1c41bdea0'UIViewLayoutMarginsGuide'.trailing == _UIButtonBarButton:0x10366fa90.trailing   (active)>",     "<NSLayoutConstraint:0x1c0298ba0 'UISV-spacing' H:[_UIButtonBarButton:0x10366e4a0]-(0)-[UIView:0x10366f120]   (active)>",     "<NSLayoutConstraint:0x1c0298bf0 'UISV-spacing' H:[UIView:0x10366f120]-(0)-[_UIButtonBarButton:0x10366f310]   (active)>",     "<NSLayoutConstraint:0x1c0298c40 'UISV-spacing' H:[_UIButtonBarButton:0x10366f310]-(0)-[UIView:0x10366f8a0]   (active)>",     "<NSLayoutConstraint:0x1c0298c90 'UISV-spacing' H:[UIView:0x10366f8a0]-(0)-[_UIButtonBarButton:0x10366fa90]   (active)>",     "<NSLayoutConstraint:0x1c02996e0 'UIView-Encapsulated-Layout-Width' UIToolbar:0x103598690.width == 0   (active)>",     "<NSLayoutConstraint:0x1c4282fd0 'UIView-leftMargin-guide-constraint' H:|-(0)-[UILayoutGuide:0x1c41bdea0'UIViewLayoutMarginsGuide'](LTR)   (active, names: '|':_UIButtonBarStackView:0x103652760 )>",     "<NSLayoutConstraint:0x1c4282f30 'UIView-rightMargin-guide-constraint' H:[UILayoutGuide:0x1c41bdea0'UIViewLayoutMarginsGuide']-(0)-|(LTR)   (active, names: '|':_UIButtonBarStackView:0x103652760 )>" )
      

      After getting this error the APP keeps working fine. But in case I use the inAppBrowser plugin and display an input element on a page, after closing the browser and coming back to the APP it gets frozen.

      I have tried by updating the Cordova iOS version and installing the cordova keyboard plugin with not result (different solutions suggested on different blogs).
