After updating to Xcode 11 and iPadOS this is how my view looks:

Before the view was filling the whole screen.
When I switch to iPhone layout the issue disappears, but stays on all iPads.
I had the same problem. I verified this began with iOS13. The fix in my case was to change the presentation style of the View Controller from "Automatic" to "Full Screen".
I want to understand better what changed here from 12 to 13, and if this is a proper fix. I'll update with anything else I find.
For context, my View Controller was being presented with a "Show" segue, which is an adaptive segue. So perhaps the adaptivity defaults have changed in iOS13.
You might want to define some constraints for regular width and regular height using size classes.
I don't know if this is a bug with AutoLayout or Xcode but I've realised that if I run my application on a device which isn't the same size as the device in my storyboard, the elements are adopting the incorrect size.
I.e. Selecting View as iPhone SE and running the application on an iPhone 7+ The size of my tableview is the width of an iPhone SE screen, this fixes itself when I reload the view and then it then adopts the width of the iPhone 7+ screen.
Just a note as well the table view doesn't have a fixed width and is pinned to the top, bottom, left and right with 0 spacing and also I'm changing the height of the cells programmatically in code if this could affect it at all as well.

Views that come from a xib (or storyboard) have their IB frame values when they are created, before they are added to the view hierarchy. So a case like you describe is probably that something is accessing a view loaded from a xib before it has become part of the layout process and resized.
This would also explain why it's fixed when you go away and come back. The first time, it got the values before they were final, but the second time the values are already final and correct.
Layout code called fromviewDidLoad() for view controllers, or awakeFromNib() or initWith(coder:) for views is the likely cause. Layout code called from viewDidLoad() is especially problematic because it was fine up to iPhone 5s, but would now cause this problem.
It's impossible to say what exactly the issue just from this. From the NSLog statements visible in the video, the issue is whatever code calls that "weather view width". That is being called too early in the layout process. It needs to go in viewWillAppear or viewWillLayoutSubviews to make sure the correct values are ready for whatever calculation is dependent on that. Hope this helps.
I can't seem to recreate this. I would recommend double checking for any updates for Xcode and the Developer tools (softwareupdate --install -a).
Incase you haven't, restart Xcode.
EDIT: Disregard this answer, please read Mike Sand's post.
Try self.view.layoutIfNeeded in viewDidLoad or in viewWillAppear
I'm converting an app that I made for iPhone to be used on iPad. Using constraints on the Xcode 6 storyboard is killing me right now.
With my rep score I can't post an image of what I'm getting, but basically even when I set the constraints and the placement of the object (a UIView) on a storyboard sized for iPad, all the objects on the viewController fill only the top/left area of the screen.
What's the best way to handle this?
-- when you change size of view, other view will be auto change to {0,0,0,0}, isn't ?
but it doesn't change in the right panel.
it is your storeboard files some settings have some wrong.

Check for those points:
hope this can help you.
I encountered a weird problem with a UIView in my Application. I placed some UIButtons, UISlider, etc. on a View. Which looks like this:
However, on the Simulator and on my iPhone it looks like this:
The button "+1 min" is not aligned with the other controls anymore.
The correct x-coordinate is 236. When I inspect the value in the debugger, I get 243.
I already checked the storyboard-file, which has the right value.
Why is it affecting only this button? And more importantly how do I fix this?
If you have used Interface Builder.. Then definitely you have to do changes for autoresize in Interfacebuilder.. Try this it may solve your problem..
I have a view that needs to have its frame manipulated programmatically - it's a kind of document view that wraps to its content which is then scrolled and zoomed around a superview by manipulating the frame origin. Autolayout fights with this at runtime.
Disabling autolayout completely seems a bit harsh because it could reasonably be used to handle layout for the other views. It seems like what I might want is some kind of "null constraint".
I had the same problem. But I have resolved it.
Yes, you can disable auto layout at runtime for a specific UIView, instead of disabling it for the whole xib or storyboard which is set by default in Xcode 4.3 and later.
Set translatesAutoresizingMaskIntoConstraints to YES, before you set the frame of your subview:
self.exampleView.translatesAutoresizingMaskIntoConstraints = YES;
self.exampleView.frame = CGRectMake(20, 20, 50, 50);
I had a similar issue where Autolayout was overriding some of my frame-setting at run time (I had a dynamic view that in some cases pushed a new view controller...pushing and then pressing Back would reset the initial view).
I got around this by putting my manipulation code in viewDidLayoutSubviews of my View Controller. This seems to get called after whatever constraint mojo gets called, but before viewDidAppear, so the user is none the wiser.
Perhaps just setting translatesAutoresizingMaskIntoConstraints to YES (and not adding additional constraints affecting that view) will let you set the frame without fighting the auto layout system.
In iOS 8 you can set an NSLayoutConstraint to be active or not. So if I'm using interface builder, I add all my constraints to an OutletCollection and then activate or deactivate using:
NSLayoutConstraint.deactivateConstraints(self.landscapeConstraintsPad)
NSLayoutConstraint.activateConstraints(self.portraitConstraintsPad)
The particular application I'm using it for here is having different constraints in portrait and landscape mode and I activate/deactivate based on the rotation of the device. It means I can create some complex layout changes all in interface builder for both orientations, and still use auto layout without the verbose auto layout code.
Or you can activate / deactivate using removeConstraints and addConstraints.
I don't know if this will help anyone else, but I wrote a category to make this convenient because I find myself doing this a lot.
UIView+DisableAutolayoutTemporarily.h
#import <UIKit/UIKit.h>
#interface UIView (DisableAutolayoutTemporarily)
// the view as a parameter is a convenience so we don't have to always
// guard against strong-reference cycles
- (void)resizeWithBlock:(void (^)(UIView *view))block;
#end
UIView+DisableAutolayoutTemporarily.m
#import "UIView+DisableAutoResizeTemporarily.h"
#implementation UIView (DisableAutoResizeTemporarily)
- (void)resizeWithBlock:(void (^)(UIView * view))block
{
UIView *superview = self.superview;
[self removeFromSuperview];
[self setTranslatesAutoresizingMaskIntoConstraints:YES];
__weak UIView *weakSelf = self;
block(weakSelf);
[superview addSubview:self];
}
#end
I use it like this:
[cell.argumentLabel resizeWithBlock:^(UIView *view) {
[view setFrame:frame];
}];
Hope it helps.
You can set the translatesAutoresizingMaskIntoConstraints type Boolean, Value Yes in the User Defined Runtime Attributes of the UIView you want in the xib/storyboard.
In my view I had a Label and a Text. The label had pan gesture. The label moves around fine during drag. But when I use the text box keyboard, the label resets its position to the original location defined in auto layout. The issue got resolved when I added the following in swift for the label. I added this in viewWillAppear but it can be added pretty much anywhere you have access to the target field.
self.captionUILabel.translatesAutoresizingMaskIntoConstraints = true
Open project in 4.5
Select storyboard
Open the file inspector
Under Interface Builder Document uncheck 'Use Autolayout'
You can split across multiple storyboards if you want to use autolayout for some views.
For me it worked to create the subview programmatically, in my case the auto layout was messing with a view that I needed to rotate around its center but once I created this view programmatically it worked.
I've encountered a similar scenario, where I joined a project that was initiated with auto-layout, but I needed to make dynamic adjustments to several views. Here is what has worked for me:
Do NOT have views or components laid out in interface builder.
Add your views purely programmatically starting with alloc/init and setting their frames appropriately.
Done.
This happened to me in a project without storyboards or xib files. All 100% code. I had an ad banner at the bottom and wanted the view bounds to stop at the ad banner. The view would resize itself automatically after loading. I tried every resolution on this page but none of them worked.
I ended up just creating a sub view with the shortened height and placed that in into the main view of the controller. Then all my content went inside the sub view. That solved the problem very easily without doing anything that felt like it was going against the grain.
I am thinking if you want a view that is not the normal size that fills the window then you should use a sub view for that.
Instead of disabling autolayout, I would just calculate the new constraint with the frame you are replacing. That appears to me to be the appropriate way. If you are adjusting components that rely on constraints, adjust them accordingly.
For example, if you have a vertical constraint of 0 between two views (myView and otherView), and you have a pan gesture or something that adjusts the height of myView then you can recalculate the constraint with the adjusted values.
self.verticalConstraint.constant = newMyViewYOriginValue - (self.otherView.frame.origin.y + self.otherView.frame.size.height);
[self.myView needsUpdateConstraints];
For those of you who are using auto layout, please check out my solution here. You should be making #IBOutlet's of the constraints you want to adjust and then change their constants.
if it's xib file:
select the .xib file
select the "File's Owner"
show the Utilities
click on: "File Inspector"
Under "Interface Builder Document" disable: "Use Autolayout"
