I'm having some issues with the constraints in my app. Here is how it looks on the iPhone 4 (that's how i want it to look, and how i usually setup my interface, is this the proper approach or not?)
Now, when i switch to the iPhone 5 screen it looks like this
and as you can see, the blue dots (which is UIButtons) are not placed where i want them to be. I made my constraints rely solely on the right side of the view (since that is the one re-sizing, i found that in order for you'r views to align themselves accordingly, it doesn't help to align them to the left side). I don't really know how to fix this. I am finding this new iPhone screen to be a real pain in the arse. Any good advice on how to work with this new screen without a lot of headache would be appreciated :)
Thanks on advance
It looks to me like the are still the same distance from the right side of your view, as you said you set them to be, while the background has stretched to fit the new size. I suspect it's actually the background that isn't doing what you want it to do (keep the same aspect ratio and show more stuff on the left), or try keeping the buttons relating to left and right to stay aligned with the stretched background image.

I am having severe difficulties finding a clear working world example of auto layout on multiple screen sizes. Most tutorials have basic stuff like a button thats centralised and then after adding constraints in Interface Builder it scales with the device. One button is simple but in my example for the iPhone 4:
There are quite a lot of labels / buttons and some that are not central. The above screen shot is exactly how I want it to look on all devices.
The app is for portrait only but I want to target all devices. I tried slowly adding constraints to items from the bottom up using a multiple of the superview to position and size items and then applying aspect ratio to UI Objects (got as far as the got it button but not the red arrow buttons) but as you can see in the next picture for the iPhone 8 plus... the white space isn't going to perfectly fill like in the iPhone 4 which will leave me with a big gap at the top.
Is there a way I can change just the iPhone 8 plus layout in Interface Builder to build a layout that caters for the extra screen size?
The iPhone 8, SE and X layouts are equally awkward with extra white space.
I tried size classes but that changes it for all phones.
Is there a way to centre what I have done so far?
How do you guys position objects in auto layout that are not centred?
Am I going about it the wrong way by applying X / Y constraints using a multiple of the superview? - same for the width. I'm only specifying widths as a multiple of the superviews width then adding aspect ratio.
I just need a real world working example I can learn the basics from or a system to create for multiple devices that I can follow. I don't want to use a 3rd party library.
I really hope someone can help point me in the right direction!

I have a problem in Swift with UITableViewCell background image. Let's say that it shows quite fine one iPhone5 but on iPhone 6Plus it is stretch and thus it looks bad. This is probably due to Aspect fill or something which I really couldn't manage to change and achieve what I want so would be the best if someone could poke sample code I am providing as well as image how it should look, so anyone can check it out and maybe give me some hint or tip or sample code or even fixed demo version.
So here it is:
Note that on left side there is a curve (like half a circle) around right side of icon. On bigger phones or tablet, that curve gets super stretch thus completely destroying the look.

Thanks all in advance for any help. I am pretty stuck with this one.
You can stretch an image while preserving the aspect ratio of a portion of that image using slicing. Xcode offers a graphical interface for doing this. The idea is that you decide what parts of the image are allowed to stretch and which aren't.

I've implemented autoresizing mask in all my the views of my project very successfully. However in the last one, which is the settings and there are a lot of sliders inside tableCells, it seems it doesn't work too well.:
I'm sure I've implemented the thing right
slide.autoresizingMask=UIViewAutoresingFlexibleWidth
for the sliders and flexible left margin for the labels.
I've also implemented table reload when the rotation takes place.
The cells are being reused ok, or at least in portrait mode they work, but when I rotate and go back I got what you see in the picture.
Any ideas on what am I missing?
Thansk in advance!
Hi all,
The images above are taken from the "Nike Boom" App. I am wondering how to do a magnified effect on the number list as shown in the images. I also want to point out that it is very very smooth animation, so screen capturing certain part of a screen and projected it back on UIView may not work (I tried that)
Thankz in advance,
Pondd
Update:
Hey,
Just so for anyone who might comes across this topic, I've made a simple sample based on Nielsbot's suggestion and posted up on github here
Please feel free to fork it, improve it and pass it on :)
Best,

It's done with 2 scroll views, one in front of the other. One scroll view (A) contains the small numbers. The second scroll view (B) contains the zoomed numbers. The frame of (B) is the transparent window. When you scroll (A), you scroll (B) programmatically, but you move it farther than (A). (I.e. if (A) scrolls 10 pixels, you might scroll (B) 20 pixels.)
Make sense?
If you've ever used Convert.app from TapTapTap they use a similar effect.
I hardly know how to explain my case other than to point to the excellent Absolute vodka app, Drink Spiration.
I am trying to make a carousel like image browsing with a little spice. I would really like to find a simple core animation explanation on how to accomplish something like the above app.
I hope someone can help with this. The solution doesn't have to be exactly the same, but just explain what is happening and it would be best if it was simple and no opengl. Just something to point me in the right direction. I don't think using just a scrollview with uiimageviews is enough.
I wrote something similar and its quite easy once you figure it out in your mind. All done justing using regular old views and animating transforms on them.
Say its 3 images on screen, and you can rotate new ones on and off ... then you will need 5 views set up (most simply just a UIImageView with a relevant image set). They are the currently selected image, the two either side of it and the ones that are, or will be animating on or off when the user flicks left or right.
Each of these 5 images has a position, an angle and an image. When the user flicks left or right each gets animated to the next position and angle, views that are about to come onscreen have their image updated to the next image in the set. If the user keeps on flicking in the same direction you simply reposition views on one side as they come off the other.
With this setup you can do lots of cool carousel like things very simply.
