What i need to make a button at bottom of screen but I've encountered an issue with iPhone 4s so please take a look at screenshot
Screenshot
so I've tried another solution which pin the button from top to the last stack-view here I've got an issue with iPhone 7 " inequality constraint ambiguity" when i change constraint from 'Equal' into 'greater than or Equal' to put it at bottom of screen as shown in screenshots
iPhone4
iPhone7
what should i do ?
best regards
An NSGridView would be perfect for this, but no such thing exists in iOS.
I would create a label and a textbox, put a vertical spacing constraint between them, then embed the two controls in a vertical stack. The stack should have a "Fill" alignment and "Equal spacing" in distribution.
Then copy and paste the stack for each of the control groups (First name, Last name, Phone, Email and Password). Select all the Stacks and embed them into another vertical stack. The stack should have a "Fill" alignment and "Equal spacing" in distribution. Constrain the stack to the top, leading, bottom and trailing edges of the view. Now you should be able to control the distance between the control groups with the spacing property in the stack view.
Try adding UiView and add button inside that UIView and add constrains to based on the place where you was need to place your button.. You can add bottom space to superview and fix the issue

I have a view with two button. I have added auto-layout. But bottom space is more in iPhone 8 plus than iPhone 4s.I want to keep the spacing ratio of top and bottom same in all iPhone. How to fix it ?
Updated
For Specific Ratio : To my understood, We can give Multiplier for Centre Vertically Constraints. Here ratio of top and bottom space will be same in all iPhone series. I gave Multiplier as 1.4
==================================
I know having several answers there. But, no one used UIStackView to add two simple buttons.
Drag two UIButton, select that two UIButtons, click Embed in Stack icon from here.
Stackview Properties
Give following things for UIStackView,
Set Axis as Horizontal, Distribution as Fill Equally, Spacing as 10 in Attributes Inspector
Stackview Constraints 1
Give constraints for that UIStackView, Check/Uncheck Margins, Left and Right = 0, Height as 30.
Stackview Constraints 2
Still, some constraints are not satisfied. Press Control and hold it, Click StackView and Drag to SuperView, you will get black pop up. Choose Center Vertically in container.
Stackview Constraints Customization
If you want to change height of UIButton or Bottom Space, click UIStackView and in Size Inspector, you can change height or move up/down.
If you are using Auto layout then set constraint like this way
set constraints to bottom and leave top constraints
1) Select both buttons
2) Click on "Resolve auto-layout issues" button on bottom and click on "Reset to selected Constraints"
You should have 2 stack views. One Horizontal that contains the 2 buttons, and another vertical that contains the previous stack view. Set the horizontal stack view to "fill" and "equal spacing" and the vertical stack view to "fill" and "equal centering." Below I've included a couple of pictures to illustrate what I mean.
THE ONLY CONSTRAINTS ARE ON THE STACK VIEWS THAT BIND THEM TO THE SIZE OF THE CONTAINER VIEW, OR PARENT STACK VIEW.
This allows you to truly create an auto layout that scales with the device's screen size.
Use Constraints like this. These buttons have bottom fix with superview.
I am new to iOS and am trying to align these TextFields in iOS. Below is how I would like it to look on an iPhone 7.
However, on the iPhone 7 Plus, the TextField shifts to the left of the center, despite my constraints.
Why is this? I have a constraint that aligns them to the Center, as seen on the right part of the screenshot.
It is very simple!! Just follow below steps,
Open you .xib or .storyboard file
Select view you have to add constraint
Click on align button at the right - bottom corner
Set horizontally in container constraint 0
Then press add constraints button
You can add any constraints to any view by following these steps
You just have to seth trailing and leading space fixed means both left
and right indicators should be red as shown in the screenshot.
For more details see the screenshots:
It will remain fixed from left and right in all the screens.
in your case is important set the width constraint.
However you can use trailing and leading constraints, in this way you will not need to set a defined width for your textfield and the position is correct for all type of devices.
If you want design like this so you have to take UITableview then take UITextfield for every cell beacuse you use every cell as view so easily manage all textfield and constraint. And also easily scrolling if device is display small.
Am new to Auto layout constraints in Xcode. I have one Bottom View like UITabBar with 6 UIButtons. Without constraints I aligned those buttons with 5 space padding with each buttons and each buttons has 50 width.
Now,I am trying to make it by using Auto layout to support all Screen sizes.
In Storyboard constrains I set equal width for 6 buttons and I made 60
space between each buttons. I set first button 0 to leading space and
I set the last button 0 to tail constraints.
I want the buttons with equal width and flexible spaces between views in all device sizes.
Can anyone pleas help me? Looking for the help. Thanks in advance.
check this image and made your constraints like below...
RESULT:- preview in different sizes
With Stackview (For iOS 9.0 and above)
NOTE: If you have to make app for iOS 9 and later then UIStackView is another option for you
With iOS 9 and Xcode 7, you can now have the expected result with UIStackView and only 3 or 4 auto layout constraints.
The following step by step uses Storyboard.
Create 6 UIButtons and 5 UIViews. Align them horizontally. Give some color to your views.
Select all your views and buttons and click on the Stack button. You will have all your buttons and colored views aligned in a UIStackView.
Select your stack view, go to the Utilities panel and select the Attributes Inspector item. There, click on the Distribution button and select "Fill Equally".
For now, your stack view's height relies on your buttons intrinsic content size. If you're fine with it, you can go to step 5. However, if needed, you can give your stack view a height constraint. Select your stack view, click on the Pin button, check the Height button, add the required value and click on the Add 1 Constraint button.
As an alternative, If you want each element of your stack view to have its height matching its width, select the first button of your stack view, click on the Pin button, select Aspect Ratio and click on the Add 1 Constraint button.
You can check that your aspect ratio constraint is correct in your Document outline (left panel) and, if you need, you can change it with a different constraint in the Attribute inspector (right panel).
Now, it's time to give some external constraints to your stack view. Select your stack view. Click on the pin button, make sure the Constrain to margin button is not select and set leading, trailing and bottom constraints to zero. Make sure that the bottom constraint is related to your view controller's view. Then, change the Update Frames button to "All Frames in Container". You can now click on the Add 3 Constraints button.
Your stack view is now set.
Further remark:
If you don't need your colored views width to match your buttons width, you can build a stack view with only UIButtons and simply add spacing to your stack view in the Attribute inspector. However, you will have to find a way to add a background color behind your stack view. Apple states about it in the UIKit Framework Reference:
The UIStackView is a nonrendering subclass of UIView. It does not
provide any user interface of its own. Instead, it just manages the
position and size of its arranged views. As a result, some properties
(like backgroundColor) have no affect on the stack view.
I've build a Xcode project with 4 different stack views:
one with colored views and relying on the embedded UIButtons intrinsic content size for its height,
one with colored views and with a UIButton "equal width and height" constraint,
one with colored views and with its own height constraint,
one without colored views but with spacing and embedded inside a colored view.
You can find this project on this GitHub repo.
iOS 9 has a new UIKit class called UIStackView. It is very helpful in stacking up views horizontally or vertically, like the way you want. You should check out this tutorial: Raywenderlich: UIStackView Tutorial
Select all the buttons and in Xcode’s Pin menu
Create a horizontal constraint from the top left view to the top right view by selecting the red line to the selected view’s right side nearest neighbor
Create a horizontal constraint from the top right view to the top left view by selecting the red line to the selected view’s left side nearest neighbor
Create a vertical constraint from the top view by selecting the red line to the selected view’s top side nearest neighbor
Select checkbox near to Height, Equal Widths and click on "Add 22 Constraints"
Spacer views should no longer be necessary unless you need space between borders.
You can create a StackView with equal spacing which will dynamically adjust the space between your stack views to use up all available space without altering the size of your subviews.
Interface builder can be a bit misleading here. the value you put in for spacing is the minimum spacing required not what the actual spacing will be.
The StackView will handle your spacing, making the size of your buttons equal you can use regular constraints for.
Everything looks fine in IB. When I run my app using an iPhone5/iPhone6/iPad sims, it's completely mangled.
In IB:
In iPhone6 sim:
In the above sim, the buttons are cut. The textfield and textview are also cut. For the TF & TV, they are aligned center but trail off the edges on both sides.
I have the buttons width set
Editor > Pin > Widths Equally
The title label is set with a
Horizontal Center in Container
constraint
The textfield and textview also have
Horizontal Center in Container
and
Editor > Pin > Width
Is there some way to fix this?
-- EDIT --
After a few tries with constraints, looks like I have everything working except the two buttons.
Current listing of constraints:
As suggested by others, you should consider using the Auto-layout feature if you plan on constructing your views using the IB.
Here are some tutorial links:
RayWenderlich.com Part One
Youtube video This one covers a bit of size clases
Hope they help.
UPDATED:
I've read your updated post, you need to add width and height constraints. The view you see in the IB right now is 600 by 600 points, and the simulator one is smaller, which means that if you leave it as is, when you run the app you'll only see what the iphone screen has the capacity to show.
You need to add more constraints than what you used, try defining an equal width for the buttons, and assign the left one a left margin constraint, the right one a right margin constraint, give both of them vertical spacing constraint related to the text view or long label, the text view or long label should have left and right margin constraints, a height constraint and a top constraint to the textfield, the textfield should have a vertical spacing constraint to the label, also left and right and height constraint, and last the label should have leff, right and height constraints plus a top constraint to the main view.
I feel that those are all you need, but Xcode will through warnings at you if it feels you are missing something.
Try it, and let us know.
I am trying to use auto layout in x code to correctly resize my view to switch between iphone 4 and 5.
I have a similar problem as the one presented in the picture. Let's consider the UILabel at the bottom is fixed.
I want the top UILabel to be at the middle of the space between the navigation bar and the bottom label. I don't know how to add a constraint that says "top space and bottom space must be equal". As a result, I can only fix one of the two constraints and I cannot get the expected result.
Thanks
The way I do this in IB, is to embed the top label in a UIView. Give that view a standard vertical spacing constraint to the top layout guide, and another to the bottom label. Also give it a fixed width. Give the label centerX and centerY constraints to this view, and it should keep it centered in different screen sizes.
How about adding a container view that fills up the space between the 1st label and the navigation bar, and then center the 2nd label inside the container view.
