I have just started learning swift and have been trying to create a layout using the scoreboard.
I have placed two textfields and set the constraints properly using the document outline. However when I run the emulator the Text Fields display wrong.
I have attached a screenshot, The left is what happens in my emulator the right is what I see in the view editor in xCode
You used the wrong constraints.....as you give x and y position to edges of the screen you can not maintain the width of the textview...
ok here is some images ...just follow it...
In first image i just give x and y position with height and width to first textfield and in the second one i give equal width and heigh to first one.
You used the wrong constraints. You set it so its constant inset from the two sides. If the screen gets small, the constant inset stays the same and it squeezes the textField.
You want to keep a constant width of the textField so no matter what size the screen is, it will keep the constant width.

I am working on IOS app and its my first app to be build on IOS. I have good experience of developing Android apps. So I have gathered basic information and knowledge about IOS development. I am working on autolayout. But I am not getting it work completely. I have seen Some developers are working on code, But I just want to use IB as I believe there will be some way to handle this.
So looking for help, Please do not down vote my this post As I am posting this after trying almost everything I get on internet.
First take a look at what I have developed and what it is :
in picture there are different numbers of simulator such as Ipad pro 12.9, Ipone 8 plus and I phone se
What I have done so far:
I have taken the View (the white box in middle). I have made it center vertically and center horizontally.
I have set view height as 300 points, and width to match the superview with some margins
I have put the Text Fields for taking Phone and PIN from user and OK button as shown in picture.
Problem & what I want:
- The problem is view is center vertical and horizontal but not its
content are. I want this view to manage its height on the basis of
its content inside. so that It can be looked as center aligned
vertically. Right now its not center align vertically
- Secondly the problem is the width of text fields, as on Ipad they looks too bad. So I really want them to be look good on all devices.
Is there any solution for this using the adaptive/Auto layout? please help me that How can I get this using IB.
Try following solution:-
Fix the width of textfield.
For label use minimum font scale(search on google).
For width and height you have to use adaptive layout.
width = 70% of superview which means multiplier for your view will be 0.7
height = 60% of superview which means multiplier for your view will be 0.6
Refer to the image:-
Equal width with the superview
Set the multiplier as 0.7
#Android Teem,
For this you need to use SizeClasses along with the AutoLayout.
Below I am trying to give you solution.
use items structure as like below. Don't use another UIView inside main view. Instead user StackView. It automatically adjust contents inside it. For more just look for "UIStackView" on Apple Doc.
Next you need to add constraints to stack view as
Leading 10 (for x)
Trailing 10 (for y)
Allign to center (for width)
height stack view will automatically adjust.
Now double click on leading and trailing constraint will open size attributes. Click on "+" icon just before Constant. It will show you a pop up. add Regular Width Regular Height for iPad and set values as 200 (I have give 200, you can give based on your calculation and requirement). this will show like below image
Now Either run or check from preview for all screens. you will get desired results. my changes show result as below
Happy Coding
Here is what you need to do. Go to the storyboard
Right click on the white area of the screen and drag the cursor to the green area.
Few options will appear, select Equal Heights
Now the white dialog box will become equal height to the green screen but don't worry. Select that height constraint and set the
multiplier to let's say 0.5 for 50% height of super view. Repeat the
same for width
Remove the height constraint and hook the bottom most button to the bottom of the view
So I have an app I'm working on, but I hit a major problem. In this app we have several images. I'm learning AutoLayout, and I can make stuff appear the same on all device screens, except for the fact that the images (and for that matter, everything) remain the same size. I want them to get bigger and smaller according to screen size. I've tried everything I know. Help!
Here you can use propotional width and height to the superView. At first Ctrl drag from your imageView to superView and set Equal Height and Equal Width. And now set the Propotional height and width to the superView from the constraint list. Here you can set your height and width with Propotional to superView with Multiplier option. And finally set your x and y position of your image Final Image. Here I have used horizontaly and verticaly centered.
Using the image here as an example:
First, place your imageview where you would like it, in terms of how far it should be from borders of the view or other objects.
Then, click on the small tie-fighter like icon in the bottom to bring up the add new constraints window.
From there, click on the four links show in red inside the red box. These tell XCode that it should be "80 units from the left most object, 80 units from the right most, etc".
Now, when you change to different devices, it will always adhere to those standards.
However, depending upon the size you selected, it may not work under certain conditions such as being rotated to landscape, or in a split view on an iPad. This is where you get into the other size classes, which you access by clicking the text at the bottom of XCode that says "w Any h Any".
One item of note, do not select the image size in width or height in the constraints window seen below. Doing so will constrain the image size, invalidating the margins put in place.
I have a view of limited width, lets say it 100.
I have multiple labels of same width inside that view and its text is centre aligned. So that text seems to be center aligned always.
Problem is when I got long text label it shows ellipses at the end of the text but I want to show whole text in one time while keeping superview width unchanged. Is it possible to attain this? If not then show how can I wrap that text if it is larger than its width. I'm new to IOS programming.
There is an issue with UILabel and autolayout. If you using it - check this answer: iOS: multiline uilabel only shows one line with autolayout
Also, check actual size of label and insure clipsToBound of superview is set to NO.
I am trying to constrain a label that is sitting on top a UIImageView. The ImageView keeps its aspect ratio for the different screen sizes so its length and width change according to the device.
I am running into an issue if I constrain the top of the label to the top of the image view at (for example) a constant of 58. For the lower resolution image that places the label where I want it visually. However on the higher resolution images that position is not where I want it visually. I have also tried adjusting the top constraint so that the constant is 0 and use the multiplier to adjust the position of the label. This however does not fix the problem and the label ends up at different locations on the image.
I really would not like to have to edit these constraints programmatically as I will have way more labels on different view controllers that would be a pain to program. Really hoping I can achieve this in IB.
I'm confused... why aren't you pinning a constant distance from the top of the label to the bottom of the image view?
I'm using Interface Builder in Xcode 6 to make an app and am having trouble getting the text fields and button to centre on the screen for different size screens.
I thought it was a matter of selecting horizontal and vertical centering in container but it doesn't seem to be that when I try it in auto layout. Actually I've tinkered around a bit and I still haven't got it.
I just want to be able to see all of my button and text fields for any size iPhone screen and right now simulator is only showing part of these UI elements like this:
I also want to do this in storyboard and not in code as I'm not at the level of doing this in code yet.
Step 1: Make sure your size class covers all the iPhone screen at least in portrait view. So, change the size class to "wCompact hRegular".
Step 2: After setting the size class properly, add the UITextFields and UIButton to your storyboard. To me, it looks something like-
Step 3:
Before, you start adding constraints, you need to remember two things-
a. Your element(UITextField, UIButton, UIView or any component) needs to know its starting position unambiguously, and
b. Your element needs to know its size meaning, its height and width.
In this case, as you want to centre your elements, I am just assuming that it needs to be centred starting from 10 scale from the left edge and should end 10 scales away from the right edge of your iPhone screen. Now, that means, it's width will be different based on the screen size, but its height will be same.
So, I just add the constrains following way for the 1st text box-
Notice, in the size inspector, I set the text box's starting point, x and width in a way that it is 10 pt away from left edge and 10 pt away from the right edge. Don't worry, it's just simple math.
For the 2nd textField, I add the constrain, the same way-
Lastly, for the button, the constrains are following-
Now, you are good to go. Everything is centered.
By using your size class selector in the bottom of the storyboard window, set you sizes as any width and any height and then follow the below auto layout constrains. It will work for you.
First select the view you want to set the auto layout, and then select the pin option from the right bottom corner of your storyboard and then add the constrains as shown in above picture and click button Add 4 constrains
Repeat the process for all views and set the constrains as Fix the top, bottom, left and right constrains of all views except the last button that should be fix from top,left,right and fixed height.
You need to make use of the size class selector in the bottom of the storyboard window.
So for an iPhone 6 or 6 Plus in portrait you would choose a compact width and regular height like this:
And then you would do whatever auto layout stuff for the given device there
