How can I detect the views whose constraints are being unsatisfied?
[UILabel:0x14641060]
It's in error message.
It seems this UILabel has three constraints. Remove any one of these you can satisfy the constraints

I am trying to create a somewhat basic layout and am having the classic "Unable to simultaneously satisfy constraints" problem. After an hour on it I cannot track it down.
Here is the layout in interface builder:
Please note that no constraints are being added/modified in code. Everything is happening in IB.
Here is the error message I am getting:

The strange thing is this constraint <NSAutoresizingMaskLayoutConstraint:0x7f888af2ba00 h=--& v=--& V:[UIView:0x7f888ac7f2c0(50)]>, I don't get where it's coming from.
Any idea on how to solve these issues?
I had same problem yesterday. The NSAutoresizingMaskLayoutConstraint you mentioned was not the problem. I could not figure out where that constraint comes from, but it seems to be normal for collection view cells.
The problem is that the constraints cannot be satisfied. Take a look at the first set of constraints that are not working:
"<NSLayoutConstraint:0x7f888ad8b700 H:[UIImageView:0x7f888ad8ce40(90)]"
"<NSLayoutConstraint:0x7f888ad8f910 H:|-(8)-[UIImageView:0x7f888ad8ce40] (Names: '|':UIView:0x7f888ad8cd70 )>"
"<NSLayoutConstraint:0x7f888ad8fb40 UIView:0x7f888ad8cd70.trailingMargin == UILabel:0x7f888ad87790'#username'.trailing + 10>"
"<NSLayoutConstraint:0x7f888ad8fb90 H:[UIImageView:0x7f888ad8ce40]-(14)-[UILabel:0x7f888ad87790'#username']>"
You have 8 points from the left edge to the image view.
The image view is 90 points wide. You have 14 points from the image view to the username. Then the username is constrained to the trailing margin with 10 points space.
Username is a UILabel and has intrinsic size. Suppose that for a given user it required 40 points to display the username. Your constraints would result in a screen width of 8 + 90 + 14 + 40 + 10 = 162. That would be a very narrow screen! These constraints cannot be satisfied.
The thing to do here is remove this trailing constraint:
"<NSLayoutConstraint:0x7f888ad8fb40 UIView:0x7f888ad8cd70.trailingMargin == UILabel:0x7f888ad87790'#username'.trailing + 10>"
If you are really concerned that the username could be too long, you could try keeping this constraint, but changing it from EQUALS 10 to GREATER THAN OR EQUAL to 10.
I had a similar problem with a UICollectionView in a Storyboard.
The cause for this error is the size of the contentView of the CollectionViewCell. It uses the default size which is (50.0, 50.0). This might be an InterfaceBuilder-Bug.
A fix is to change the priority for your imageView.width (90) and the buttons width (52) to 999.
I have this warning when building my app. I'm using a storyboard, but all constraints are proper over there.. I don't know where else I have to look..

Ok, some constraints are contentious but I don't set any constraint by myself, they are all set automatically in Interface Builder and I can't remove them. What I want is pretty simple, a scrollview, with fixed width and 100% height, and a collection view, with remaining width and 100% height.
Autolayout makes me crazy, any idea ?
Edit : Here are my constraints defined in IB
Error was caused by an automatic constraint, more precisely this one :
"<NSLayoutConstraint:0x1f5525e0 H:[UIScrollView:0x1f551910]-(970)-| (Names: '|':UIView:0x1f547740 )>",
As it is added by IB you can't delete it, so for ignoring it I have set the priority to 1.
I seem to be having some problems settings up my constraints programmatically for a UITableView I am using. My attempt is below, and have tried every combination of using the translatesAutoresizingMaskIntoConstraints possible.
self.view.translatesAutoresizingMaskIntoConstraints = NO;
_tableView.translatesAutoresizingMaskIntoConstraints = NO;
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:#"V:|-100-[_tableView]-20-|" options:0 metrics:nil views:NSDictionaryOfVariableBindings(_tableView)]];
I am just trying to add a space to the beginning and bottom of my UITableView on a UIViewController. Could anyone help with this?
