I am developing an iPhone app in which, i have made this page using autolayout
but it shows unwanted spaces above Register Me(yellow button) in bigger iPhones
Constraints given are:
top,bottom, leading and trailing with respect to its subviews to all the controls. (there is no warning or misplaced constraints i see in xcode)
Here is the screenshot of iPhone 4s
Here is the screenshot of iPhone 6+
I want to minimize the empty spacing in bigger iPhones...
How do i solve this problem?
Please help and thanks in advance
Heres a suggestion for you. You have roughly seven regions of interest there. First one is the title 'Register Kano .. ' etc. Then there are 5 text entry areas - name, email, password, etc. Finally you have 3 small lines of info text - I would count this as one final area, so 7 in all.
What I would do is create 7 parent UIViews to put that stuff in. I would give them 'equal height' constraints, and make them sit above and below each other with no gap. Then as the iphone screen changes height, those areas stretch out height-wise to fill the area. Heres a rough mockup :
Select all those UIViews and select the 'equal heights' constraint :
Then every view except the bottom one needs these constraints (top, leading trailing to superview 0px)
Then your bottom view needs those plus 'bottom' too :
So all that remains to do is to put your content in each of those boxes, but centre them in terms of vertical position relative to their superview.
If your intent to target iOS 9 users, you should use UIStackView, the provide a lot of flexibility in terms of alignment and distribution.
If not, then you or your design team has to find a solution.
You can update the margin contraints of your controls on big devices.
This would add space between each rows on big screens, will looks better as you ask.
Something like :
myControl.heightConstraint.constant += 20.0f
This is how I would do, but you have to decide how you update your layout for big devices
#Krunal you can use the size class and set the constraints accordingly so it will give a brief idea how to fit the UI design for every device!!
you can set constraints relative to height of your base view. This will make your interface objects evenly distributed over layout. Lets assume you have 8 regions. for registerLabel
registerLabel.leading = baseView.leading
registerLabel.trailing = baseView.trailing
registerLabel.top = baseView.top
registerLabel.bottom = baseView.bottom * (1/8)// it will be always proportional to height of view
then for icons at the beginning firstIcon
firstIcon.leading = baseView.leading + 10
firstIcon.height = firstIcon.width
firstIcon.height = baseView.height*(1/9)// to give a gap between icons
firstIcon.bottom = baseView.bottom * (2/8)
and then you can set textfield's constraints according to firstIcon
for other icons you can go on with 3/8, 4/8, 5/8, 6/8 and set the relative textfields constraints according to that icon.
and lastly for registerMe button
registerButton.leading = baseView.leading
registerButton.trailing = baseView.trailing
registerButton.bottom = baseView.bottom
registerLabel.height = baseView.height * (1/8)
With this approach your icons size also decrease and increase relatively with height of view and all the page will be filled.
baseView is view of controller.
What is happening here, you kept the width according to superview ie phone width, but your height is fixed.
Do one thing instead of giving Height constraint, use aspect ration in combination with leading , trailing and top constraint. When view will stretch widthwise , your component's height will also Increase and fill the extra space for iphone 6.
This is the best thing you can do keeping the same layout and design pattern.
Seems you have given some fixed height in views.
As every element is depends on it above and below elements constraints, this might be possible of empty space.
So try to divide the View part then the dependency of constraints will reduce.
If you don't want to show empty space, then use center horizontally to one of the element which will look good, here it may be the third field.
Then start giving same constraints to Register button. Sure it will help you in resolving this issue.
Hey its the best solution for you is stackView
Combine your objects in single stackView.
You can combine your object vertically and also horizontally.
It will decrease your space and view will arranged in awesome manner.
You can select your objects like this.
Click here to make it stack.
Now you can reduce your space like this.

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
I need my buttons to stay in the same positions for all phones.
I want it to look like this on all iPhones:
But when I switch to a larger size phone it does this, it also looks ugly on smaller phones as well:
That is a VERY broad question, as a lot of iOS UI depends on autolayout. I suggest you work through these tuts at at least AutoLayout. From your screen shots, it looks as if you have set a width constraint on your view with the green background instead of pinning the leading, trailing, top, and bottom to the edges.
Auto layout is, in essence, a system that performs calculations based on constraints. This means that to perform what you want, you need to add constraints to each of your objects so that the compiler knows how you want to resize your UI. But like others have said, that is a very general question. I suggest looking into the topic a bit before asking, so you can narrow down your question and get better answers.
You need to define positions for all your button or views. You need to define atleast 4 constraints for all your view. By adding constraints you tell your views where they should be placed on all screens. You define their positioning with respect to screen by adding constraints.
When you add trailing, from top and width and height constraint you tell that view should be placed in fixed position i.e. x , y and occupy defined space whatever may be screen size.You can opt for fixed width or height. Instead of fixing height and width you can also define leading or trailing constraints for the view. Constraints will adjust views frame according to screen size.
For beginning you can opt for some tutorials available online. You can check Raywanderlich here. Hope it helps.
I'm struggling a bit with constraints on iOS with the differents screens sizes nowadays.
I tried google and stackoverflow to find a solution but my english does not seem fluent enough to find an answer.
I got 4 buttons verticaly aligned, the first and the last one are constrained by the edges of screens (kinda easy). But I'm really struggling with the constrains of the 2 middle buttons. I can't find a way to make them equally spaced from the left and right buttons on every size screens.
Is there something easy and tricky to make these constraints right ? Or am I doing it wrong and should I try to do it programmaticaly ?
Thanks
Add three invisible views in middle of each button, make their width equal with each other with constraint then your four buttons will be equally spaced. For the Y then you just need to pin it at your desired place.
If you are going to support only iOS 9 and higher, then use a UIStackView.
The solutions to this problem is very simple. This can be solved using the concept of "spacer views". You have to place invisible views between each red coloured view. You would be requiring 3 in your case. Then make their background as clear colour. .
Next, make their width equal and constrain their edges to the views that are after and before that view. You then define the size for red coloured view.
REMEMBER dont give the "clear coloured views" any fixed width. It would be determined by the runtime.This would solve the problem. Tell me if any more information is required.
Here is a blog post for the solution for this
http://adamdelong.com/fluid-layouts-with-auto-layout-size-classes-spacer-views-and-constraint-priorities/
This is the youtube video for this
https://www.youtube.com/watch?v=eSG-3-QpmWk&feature=youtu.be
Besides Tj3n's answer with views between buttons, you could use
A UIStackView (iOS 9!) where you use for settings Axis: horizontal, Distribution: equal spacing
A Toolbar (depends on what you want to do with your buttons) with toolbar items and flexible Space between them
Why not size classes? Apple introduced the concept of adaptive user interfaces in iOS 8 relying on a combination of Auto Layout and size classes.
If you aren't aware of what is size classes, there are plenty of tutorials available, please find one.
Summary: Apple very cleverly removed two story borads for iphone and ipad and made a single story board for universal app. No you dont have to struggle trying to apply autolayout constraint that satisfies all the screen sizes :)
Below are few of the size classes and their meaning :)
Regular width x Regular Height ----> iPad Potrait mode/ipad landscape mode
Compact width x Regular Height ----> iPhone 6 plus,iPhone 6,iPhone 5s,iPhone 5,iPhone 4s potrait mode
Compact width X Compact Height ----> iPhone 6,iPhone 5s,iPhone 5,iPhone 4s landscape mode
Regular width x Compact Height ----> iphone 6 plus landscape mode.
You can select the size classes you want to support from story board :) and start applying constraints specific to each size classes (like buttons in middle) or if you have generic one (like your buttons fixed to screen) for all the size classes.
You can deploy, remove, reuse or delete the constraints form various size classes.
SUMMARY: Buddy, If you are not using size class yet, its a high time to start using it :) There is a wonderful video on it in apple WWDC sessions 2014 i believe. Download, watch, start playing with it.
Happy coding :)
you can use equations to get this appearance.
use views' trailing points to get this.
View1.trailing = superview.trailing*(2.0f/9.0f)
View2.trailing = superview.trailing*(4.0f/9.0f)
View3.trailing = superview.trailing*(6.0f/9.0f)
View4.trailing = superview.trailing*(8.0f/9.0f)
if you make View1.width = superview.width*(1/9.0f) you can achieve what you want.
there are a lot of similar solutions for this issue. but the base is using trailing points.
It may also be done with using centerX positions of Views.
View1.centerX = superview.trailing*(3.0f/15.0f)
View2.centerX = superview.trailing*(6.0f/15.0f)
View3.centerX = superview.trailing*(9.0f/15.0f)
View4.centerX = superview.trailing*(12.0f/15.0f)
Thanks to LearneriOS answer, I solved my problem.
In order to get my wished result, I created 3 views with 10 width.
My first and my last button were already constrained. I constrained my first extra view to my first button with Horizontal spacing then i constrained my first extra view with the Center vertically in container. I then constrained my extra view to his own width and heights.
There come the important part: I did go on the constraint menus and selected the width constraint. The value inside was still 10 but I did change the priority from 1000 to 750.
Then I did copy my first extra view and constrained all of them to the nearest buttons, the same way I did with my first entra view but I removed their width constraint (to all the extra views but the first one) and constrained the extra views with the first one by plugging the: Equals Width.
Then I got my result, I hope it was clear enough and thanks again.
I have an app which I've designed in the width:any height:any universal size template in XCode (Swift). Basically, I have a custom cell, with its own uitableviewcell class too, and two labels inside of it which display array data. Anyway, I am struggling to add the correct restraints etc, so that the labels and text inside them display properly on all iOS devices. Even though I have changed the font to be able to go to 0.2 scale, there's still sometimes overlap or text clipped in the label on smaller iOS screens. It's probably a simple thing to resolve. So can anyone help me make this layout look the same, or the equivalent, on all iOS devices and all orientations too please? Here is my design:
The fact that your labels are overlapping each other is probably that you don't have the proper width constraints.
This is what I will do, taking the left label as an example:
add constraints to the left, top, bottom margin
add a width constraint to the parent view and making it 50% of the parent width
You will need to do the similar for the right label replacing the left margin constraint with a right margin one.
Now both the labels only take 50% of the width, then they will not overlap any more guaranteed.
I have a relatively simple portrait-only UI, laid out in a Storyboard, with items which I want to vertically spread to fill both 3.5 inch and 4 inch screens.
In other words, I want the spacing between the controls to be adjusted so that the UI nicely fills the screen, irrespective of the screen form factor.
This doesn't seem like an unusual thing to want to do, however I just can't get Interface Builder (within Xcode 5) to add the right constraints - I only seem to be able to get it to add fixed vertical space constraints, which do not adjust for different screen sizes.
Does anyone know how to do this without resorting to programmatic UI construction? I've invested a lot of effort in getting the Storyboard-based UI just right.
The solution needs to work on both iOS 6 and 7. Thanks!
How to do this depends on exactly what kind of adjustment you want when the screen size changes. One way to do it to give the top and bottom most views vertical spacing constraints to the top and bottom of the superview, respectively. Add a view, I usually use a UILabel with no text, in between all the views you have stacked vertically, and give them equal heights to one another. Give one of those "spacer" views a fixed height, but edit it so its priority is less than 1000 (which means it's not mandatory that it be satisfied). Then add spacing constraints between each nearest neighbor above and below each "real" view and the "spacers", so that you have all the views from top to bottom connected together by vertical spacing constraints. When the screen size changes, the only thing that can change will be the height of the "spacers", since the priority is less than 1000, and all other constraints are mandatory. My constraints look like this:
The labels each have the standard (8 point) spacing to the "real" views above and below them. The top and bottom views should have whatever spacing you want to the screen edges.
Apple have now posted a document which describes the officially-endorsed approach to solving this problem:
https://developer.apple.com/library/ios/documentation/userexperience/Conceptual/AutolayoutPG/AutoLayoutbyExample/AutoLayoutbyExample.html#//apple_ref/doc/uid/TP40010853-CH5-SW8
Summary of the approach: insert spacer views between your controls, which have equal width/height (as applicable) constraints.
