Create one app for iphone 4 inch screen in Xcode 6.1.1 develop one page successfully and run properly in iPhone 5s. and run iPhone 6 and 6+. its show the white empty page for iPhone 6 for extra height and width. how can support for all the screen in that same code.help me new for develpoment..
This is a very generic question , it is a big topic at the beginning it might be a pain in the ass but you would be amazed how powerful it is when you master it , i would say that you should read a tutorial , let me suggest the following such as :
AutoLayout tutorial
it would be much useful if you learn the adaptive UI concepts as well it is amazing a link for it would be
Adaptive Layout Tutorial
When dealing with Autolayout keep in mind that a major difference between it and using the frames is that you depend on relations between objects position and each other rather than fixed points , try to minmize usage of constants for alignments and keep it as much as possible relative for each other at the same time make sure that each object has a constraint to calculate its width, height , top and bottom positions

I am new to iOS platform but still been able to build my first app in the last 3 weeks. Coming from android, I was able to leverage of some of the knowledge I had to adapt quickly to swift and iOS but I struggle with auto-layout in the storyboard. I have not been able to get a flow that works.
I am currently using Xcode 11 and have tried to UIScrollView but to no uniformity. Whatever I arrange correctly on iPhone 11 deforms on iPhone 8 or lower.
I have watched different tutorials on youtube, lynda.com and pluralsight but to no avail.
What is the best possible way to use auto-layout across different screens like we have in android with constraint layout/relative layout?
I recommend using anchor constrains programmatically. Setting border relative to different items will provide autolayout in all devices. If you post a screenshot of your needs , it might be easier to provide accurate answer. Also keep in mind that superview borders in iphone 8 and lower version differ from borders in higher version according to the top notches. You need to set your views relative to safe area of the superview.
Now, before all you angry people say "hOLY DUCK THIS IS A DUPLICATE", just wait. I've seen at least 10 articles on this, NONE of which have been a help. My issue is im trying to make my iPhone app (xcode 8, swift 3.1, iOS 9 deployment)
match all screen sizes and set the app size to the NATIVE screen size on the device. I've seen the launchscreen articles, and they have been no help because they aren't specific. If somebody could either provide a tutorial or link one so I can figure this out, that would be great. Thanks all
You want to set the constraints for your views.
Here's a tutorial specifically for XCode 8:

Here's another for Adaptive Layouts:

At their most basic, constraints lock parts of the view to known areas (top, bottom, left, right) on the screen. Compounding constraints can be helpful for specific problems, but they get complicated quickly. If you're having problems getting them to work properly, I have found it works best to remove all of the constraints and start again with something simple and increase complexity as needed.
For the past few months, I have been trying to learn iOS development. Most of it has relatively easy, however, one thing has been very difficult for me. AutoLayout. After I grasped constraints, I thought it would be easy, but I am having real trouble getting my layouts to look well on both iPhone and iPad devices. I can design pretty well for iOS. Recently, I was building an app where I put two buttons in the ViewController. on iPhone, I set the constraints of the buttons to equal the width of the screen (plus the screen margin), and set a reasonable looking height to the buttons. On iPhones, my layout looks great, but on iPads (especially the newest iPad Pro), things look horrific. Full width buttons look great on the iPhone, but on iPad they need to be a lot smaller width wise and a lot bigger height wise. Likewise, my images look great on iPhone, but are too small on iPads. In CSS, I could just use MediaQueries, and on Android, resource qualifiers on the values and layouts.
What are my choices here? How can I design my layouts to look nice on both iPhone and iPad when certain dimensions need to be different based on screen size, screen resolution, etc.? Constraints seem to be good for enforcing dimensions, but not adapting them.(Except maybe the Aspect Ratio constraint)
What features of the AutoLayout system can allow me to accomplish responsive layouts among larger screens and Retina resolutions? What are some common tips / tricks for developing responsive layouts.
You can use size classes in order to build for different screen sizes easily. raywenderlich.com has a solid guide on adaptive layouts.
You can use size classes to design differently for iPhones and iPads and also you can use proportional width height to look perfect based on the height ratio of all devices. If you want to choose first option then you can go with any tutorial available but if you want to choose the second option which is the little difficult way but time saving way then you need to really understand the sizes of devices and need to understand what actually proportional width and height constraints do. Thanks.
In I phone 5s simulator its working fine! I have one label,one image view and one button.As you can click on the link and see the picture now so i tell you that I used my image view as a background and the label is in the middle and the button is in the lower middle so i want that to look same in all the devices. i don't know anything about constraints.I am using Xcode 6

I suggest you to take a look at this youtube tutorial. I learned how to make the constrains by watching it. The tutorial teaches how to make the similar layout as you required.

Hope this is helpful~
Autolayout is the tool used to make UI look similar across all devices, you should try to learn it if you want to continue to develop IOS apps. The concepts are pretty basic and are used throughout other languages.
This tutorial is useful if you want to create the auto layout using storyboards.
This tutorial is useful if you are making the view programmatically. I tend to use code for auto layout but it is just a preference, storyboards is fairly simple so I would suggest that. If you are going to do it in code a is to forget setting the autoresizing mask into constraints to false. You have to set this property on all the views you want to use auto layout for.
view2.setTranslatesAutoresizingMaskIntoConstraints(false)
Background ImageView
Select Image ->Pin->Uncheck Constraints to margin-> select top,bottom,left,right.
Button
Select Button-> Pin->Uncheck Constraints to margin->select bottom,left,right,Height.
label
Select label->Align->Center horizontally and Center Vertically in Container.
Pin->Width,Height.
If it is working for iPhone 5 but not another layout then this is probably happening.
There are demensions in the centre of the lower tab bar of story boards
There are screen size settings in the story board and regular*regular is the only one that is universal to all orientations and sizes of the ios device. if you set constraints while viewing in regular by compact (landscape for 5.5 inch iPhone) then those constraints will only be apply to 5.5 inch iPhones in landscape and if you tried running on a smaller iPod it would be as if you never set the constraints. the constraints for the 5.5 inch iPhone would not apply to the small iPod
if constraints were made in compact by compact and you were viewing the story board in say regular by compact then you would get an error saying that things are misplace and will not appear in the same at runtime. view the storyboard in the same dimensions that you set the constraints and you should not have an issue.
There is an option to simulate the device you want to run on specifically in storyboard and it can be say only 5.5 inch iPhones or something, whatever device.
go to paul hegarty developing iOS apps with swift on iTunes you if you want to learn more. He is a good source.
I started one new iOS apllication. And that application requirement is app should support from iPhone 4 to iPhone 6 Plus. I am very much familiar with using Xib files. So far I differentiated my apps with iPhone 5 and below iPhone 5. For that I Used 2 Xib files for one is for iPhone 5 and other is iPhone 5 below according to device height I added like that. But now apple has relased iPhone 6 and iPhone 6 Plus with iOS 8 along with XCode 6. For these 4 types devices,
1) iPhone 4 2) iPhone 5 3) iPhone 6 and 4) iPhone 6 Plus do I need to add 4 Xibs or any other solution.
To learn Storyboards, now I don't have that much time because my app has already release date confirmed from Client. But I will learn about sotryboard in future definately.
I have tried with Autolayout concept, but its not worked for me. and I dont have full awarness on Autolayout concept also. Yesterday I started my new project with XCode 6, So I taken iPhone 6 view and tried to use autoresizing and autolayout but not worked for me and views are overlapping. I know for different devices creating different xibs is not good practice. For creating each device with each xib would take huge time. I am really bothering about this how to handle different devices from yesterday onwards. Please somebody help me to came out from this issue. Really highly thankful to you. If anything mistakes in my content please forgive me.
Your question deserves a longer answer than StackOverflow can provide, but there are a few pointers I can give you.
For each of your xibs, enable Size Classes and Autolayout.
Set each xib root view's size class to width Any and height Any, which I believe are the defaults.
Design your interface in a way that looks decent on this theoretical Any x Any device.
I highly recommend using a UIScrollView at the top level of any view controller's view hierarchy.
Use constraints to anchor the controls. I find it easiest to start with the control in the top left corner, anchor it to the containing view's top and left sides, and then work your way down and across until all of your controls are constrained on all 4 sides, or on one vertical and one horizontal size, along with explicit height and width. Be generous with the greater-than and less-than relationships in your constraints.
To customize for each device layout, switch the size class to the desired combination. Note that any constraints you add, change, or remove, as well as any controls that you add or remove, will be changed only for the current class size. Do this for each different size class that you're going to support. See Apple's reference for which size classes are used for each device.
Test your layouts using the Resizable Device simulators.
This is hard work, but it sure beats having to maintain a different xib for each device size.
