I am trying to figure out a constraint issue when presenting my UIAlertController.
2019-04-26 11:40:42.140007+0100 MyAPP[12811:3974220] [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.
(
""
)
Will attempt to recover by breaking constraint
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in may also be helpful.
I create and present the UIAlertController using the following function
#discardableResult
static func showOptionsModal(withOptions options:[String], sender:UIViewController ,holderView:UIView, arrowPosition:UIPopoverArrowDirection, completion: ((_ option:Int) -> ())?)->UIAlertController {
let moreActionsCellSheetController = UIAlertController(title:nil, message: nil,preferredStyle: .actionSheet)
for (i, option) in options.enumerated(){
let optionAction = UIAlertAction(title:option, style: .default){ (_) in
completion?(i)
}
moreActionsCellSheetController.addAction(optionAction)
}
if UIDevice.current.userInterfaceIdiom != .pad {
let actionCancel = UIAlertAction(title:printLocalized(withKey: "messages.cancel", targetSpecific: false), style: .destructive){ (_) in
completion?(-1)
}
moreActionsCellSheetController.addAction(actionCancel)
}
moreActionsCellSheetController.view.tintColor = UIColor.black
moreActionsCellSheetController.popoverPresentationController?.sourceView = holderView
moreActionsCellSheetController.popoverPresentationController?.sourceRect = holderView.frame
switch arrowPosition {
case .up:
moreActionsCellSheetController.popoverPresentationController?.sourceRect.origin.y = 0
moreActionsCellSheetController.popoverPresentationController?.sourceRect.origin.x = (-holderView.frame.width / 8)
moreActionsCellSheetController.popoverPresentationController?.permittedArrowDirections = .up
case .right:
moreActionsCellSheetController.popoverPresentationController?.sourceRect.origin.y = 0
moreActionsCellSheetController.popoverPresentationController?.sourceRect.origin.x = 0
moreActionsCellSheetController.popoverPresentationController?.permittedArrowDirections = .right
case .down:
moreActionsCellSheetController.popoverPresentationController?.sourceRect.origin.y = holderView.bounds.width/2
moreActionsCellSheetController.popoverPresentationController?.permittedArrowDirections = .down
case .left:
moreActionsCellSheetController.popoverPresentationController?.sourceRect.origin.y = holderView.bounds.height/2
moreActionsCellSheetController.popoverPresentationController?.permittedArrowDirections = .left
default:
moreActionsCellSheetController.popoverPresentationController?.sourceRect.origin.y = 0
moreActionsCellSheetController.popoverPresentationController?.sourceRect.origin.x = 0
moreActionsCellSheetController.popoverPresentationController?.permittedArrowDirections = .any
}
sender.present(moreActionsCellSheetController,animated: true, completion: nil)
return moreActionsCellSheetController
}
I am added a symbolic breakpoint and added an action like so:

The Constraint issue only seems to happen with an iPhoneX. Ipads and iPhone 7 and 7 plus don't show the the issue.
Thank you.
I got similar issue in iPad.
I fixed it removeing sourceRect and change view.frame to CGRect(x, y, 0, 0).
So, How about removing moreActionsCellSheetController.popoverPresentationController?.sourceRect in your code?
sourceRect means UIAlertController's position. So I think you'd better setting it like CGRect.
Thanks.

Hi I am working on app and in this I have a UITableView With custom cell design. When I go to this view controller I can see there is a bunch of issues stated there in design. So I thought to fix them. Just quickly jumping into the issue and here it is what I was looking at
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

This is my first time of fixing UI view. I got great help on this SO thread. But I really did not get how did he solved the issue. I did same thing to print out details of my design issue so I got something very much clear but still I am not getting which thing to settle first. Please guide me through or share something that can help me in identifying issues. thanks in advance. Following is the trace that I got when applied Symbolic break point as suggested in SO link.

If I in Google Sheets have a series defined as
[29060, 29062, 29331, 29332, 29333, 29334, 29335, 29336, 29337, 29338, 29339, 29340, 29341,
29342, 29372, 29373].
How do I make them line up in intervals like this?
|To |From |
|29060 |29062 |
|29331 |29342 |
|29372 |29373 |
I can't find any good answers for this anywhere. Please, help!
Data/Formulas
A1:
29060, 29062, 29331, 29332, 29333, 29334, 29335, 29336, 29337, 29338, 29339, 29340, 29341,
29342, 29372, 29373
B1: =transpose(split(A1,",")). Converts the input text is an a vertical array.
C1: =FILTER(B1:B16,mod(ROW(B1:B16),2)<>0). Returns values in odd rows.
D1: =FILTER(B1:B16,mod(ROW(B1:B16),2)=0). Returns values in even rows.
E1: =ArrayFormula(FILTER(C1:C8,{TRUE();C2:C8<>D1:D7+1})). Returns values that start a range.
F1: =ArrayFormula(FILTER(D1:D8,{D1:D7+2<>D2:D8;TRUE()})). Returns values that end a range.

I have seven elements side by side for which auto layout should calculate its width and the parent view should determine it's height. On this parent view I want to add a line to separate the areas more clearly. When adding this line (a UIView with a background color) I get some black bars at the right side of the parent view (container for the seven elements) and also one of the other views.
If I don't add this line it does work fine on iOS 7. On iOS 8 it does work even when the line is present. These are my auto layout constraints for the line:
V:[line(==0.5)]| and H:|-0-[line]-0-|
The seven labels have the following constraints:
H:|-0-[first][second(==first)][third(==first)][fourth(==first)][fifth(==first)][sixt(==first)][seventh(==first)]-0-|
and
V:|[first]|
and so on.
Why does adding the line not work for iOS 7 auto layout system? How can I add my line correctly?
Edit:
My seven labels are in a container view - the header. The header is placed together with a collection view (added as child view controller) on a normal view controller. This "main" view controller (or container if you want) has the following constraints:
H:|-0-[header]-0-| - header holding the seven labels
H:|-0-[monthView]-0-| - collection view
H:|-0-[toolbar]-0-| - toolbar
V:|-0-[header(==15)][monthView][toolbar(==44)]-0-| - vertical position all three elements
I got it managed to get an auto layout trace once all views where loaded:

Here you can find the recursive description after the view was loaded.
I think I'll never find out what is wrong with the auto layout system on iOS 7. But I now use a workaround: Instead of adding the line to the same view like the seven labels I add it to another container. Pseudo-Code:
weekdayHeader = [label1]-[label7]
monthViewHeader = [weekdayHeader][line(==0.5)]
And the monthViewHeader is added together with my other views (UICollectionView, UIToolbar) to my main view controller/container.
I want help with my UIScrollView:
I have implemented my UIScrollView in my project and everything works fine but I have problems when Im trying to implement zoom, but this is not as the zoom when we are looking a picture. I am trying to zoom out. My app begins as this graphic when it launches. Lets suppose that I have a UIView in the screen which is bigger than my screen.

How can I do it?
Set scrollView.minimumZoomScale = 0 then you can zoom out as much as you want. If you don't want to zoom out too much, give it a reasonable value.
I am trying to debug a UI Layout and all the elements I have added in the code are labelled with [self.element setTranslatesAutoresizingMaskIntoConstraints:NO]; The only thing that is set in XIB file is the background color of the view (one of many views in a tabbed viewController.
When I look at the NSLog I am seeing the following:

As you can see from po commands, I am getting NSAutoresizingMasktLayoutContraints. I thought this shouldn't happen?
How can I ensure that I don't get this?
Ok.. I have figured out that the constraints did not appropriately address the relationship between each other. I have updated the code and now I can get clean constraints for all aspects, except for the main UIWindow, which I am sure is just because of the problem with the UILayoutGuide being ambiguous -

The UILayoutGuide is not set anywhere in my code, so I am not quite sure what do with it.
