I have problem in xcode, I'm trying to add button in the image but the position comes in the different positions from iPhones screens
Here is the picture from my storyboard:

and here are the preview from others screens :
iPhone with 3.5 and 4 inch screen:

I'm using the auto layout.
help :(
You have to use auto layout and there's no other way unless you write a very ugly code where you hard code the center for those buttons for each screen size!
I recommend reading about auto layout, it is little weird to start but you will get used to it after a while
here's a very good tutorial which helped me a lot http://www.raywenderlich.com/50317/beginning-auto-layout-tutorial-in-ios-7-part-1

I have developed my App on XCODE 8 which by default removes iPhone 4 emulator and I didn't notice that until I finished my app, and I used Auto layout to make the UI fits all iPhone screens and that what happened (the layout was good on iPhone 7,6,5) the problem is when I additionally installed iPhone 4 emulator I found that the layout is totally missed up and unreadable/usable.
So what options do I have to solve this and make it fit the iPhone 4 screen too with Auto-Layout with missing up the other sizes ?
Here is screen shot of my Login screen on iPhone 6 (4.7") vs iPhone 4 (3.5")
You must always give constraints with respect to other alternative buttons or a view, it should not be hard coded. Try making views programatically, it will be more easy and helpful to you.
It seems like your constraint is set to have a fixed distance related to the top of your screen. So when the screen height get smaller, your views are pushed out of the screen. So to better adjust views position, you can have your views to be related to vertical center. Say your login box is in both horizontal and vertical center, not metter you are using iphone 6 or 4, you should always see your login box.
I've checked a lot of different websites and stackoverflow answers, and I'm still stuck.
I developed an app for iPhone and iPad targeting iOS 7.1. I have two storyboards, one for each device. The app only displays in portrait mode. I cannot seem to get the app to display full screen on the iPhone 6 simulator.
I've tried numerous things, I followed the advice linked here by adding a Launch Screen, setting the iPhone storyboard to auto layout and "use size classes", and . Not only does that not affect the size, but the Launch Screen doesn't seem to scale properly either. If I get it to fit the iPhone 6 it doesn't fit the iPhone 5 properly.
I've tried adding the proper launch images and I don't get any errors saying the wrong image resolution is present.
I've used the storyboard as a Launch Screen described here.
Now, when I switched to "use size classes" I could manually extend the objects in the views to match up with the size of iPhone 6 (I have not tested it for 6s) but that makes it extend past the iPhone 5 boundaries. The only thing I can think of right now is to create another storyboard and detect if it's iPhone 6, but I would really like some other ideas.
Here's what it looks like for iPhone 6:
And here's what it looks like on iPhone 5:
Best advice i can give u is
Use default size class , the classic 600x600 and then use Auto Layout
Or do the reverse, take a 3.5inch size VC and apply Auto Layout on it. Everything will present itself quite perfectly if you can apply the right constraints
Here is a link for an awesome Autolayout tutorial
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 don't know if I can accomplish this because I can't find any information or tutorial doing what I need to do, and maybe this just can't be accomplish at all and I am wasting my time.
What I want to do is to shrink the white space between diffenrent element inside the same UIView for iOS 7 using storyboards and autolayout, so they can re-arrange themselves to fit nicely inside a 3.5 inch screen and landscape mode.
I've been working on this the last 3 days and no matter what I try to do with the constrains, I can't make it look the way I want it in landscape or 3.5 inch screen.
This is what I want!
Maybe some of you can give me some hint about it, or just let me know if I can even do this, because I'm out of ideas.
I am writing my first iOS app and just realized a serious problem. I was using storyboard for a 4 inch iphone screen and forgot to take 3.5 inch screens into consideration. :( It seems that this could be relatively fixed easily if I have done everything in code. But unfortunately, I have used storyboard for some parts of my app. It seems that the table views are fit perfectly but the views with some fixed subviews fail. Could anyone please give me some suggestions on how to fix this? Any help is appreciated. Thank you very much!
This is exactly what auto layout exists for. You can create a UI, using storyboards, that works perfectly for both screen sizes. You can toggle a setting in the storyboard to have it display the two different screen sizes, so you can easily see how your views will move and resize. There is also a preview mode for the storyboard that lets you see how it will look. It also lets you see how it will look on both iOS 6 and iOS 7, so that you can make sure that your UI looks good on both assuming you still support iOS 6.
If you had done this in code, it would probably have been a whole lot more complicated, especially since you have to run it each time to see what changes when you adjust your code. Graphical layout tools such as Interface Builder (what allows you to view and edit storyboards and XIB files) make supporting multiple screen sizes very easy. Plus, generally it's not too hard to make a screen designed for a 4" screen work with a 3.5" screen, in some cases you just have to make things fit a little closer together, or perhaps have the content in a scroll view.
