While I seem to have taken the gist of setting the view constraints on UIViews of storyboards, I just can't seem to figure out why constraints are not properly working in a dynamic cell prototype ContentView's subviews.
The cell is pretty simple: A UIImageView background that fills the entire cell, in front of it another UIImage and a label as following:
The background UIImageView has the following 4 constraints: 0 fixed to: trail, bottom, top and leading space to superview
The profile picture image has a fixed width and height and a constant 13pts space to leading superview and has a vertical center in container
The Label has an 8pt leading space to the profile pic and trailing space to superview, and has a vertical center in container.
This is what I am getting:
Did I miss something? I researched the issue but no answer solved the issue. However, I tried adding the following lines in the cellForRowAtIndexPath after loading the cell:
cell.setNeedsUpdateConstraints()
cell.updateConstraintsIfNeeded()
which gave the following errors at runtime:
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)

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in UIKit/UIView.h may also be helpful.
Any clues?
