I'm working on a project where I have two images, one scrolling underneath the other. The top image ("glasses") has fixed positioning and z-index=1. The other image ("quote") is left as is and is underneath the first. When I viewed the website in portrait mode on my iPhone, the fixed glasses image gets cut off, while the quote image scales down and fits within the screen dimensions. It works fine on desktop and in landscape orientation. I've tried setting the width of the glasses image to 100% and using media queries to target the phone width, but I havent had much success. The glasses just get squeezed and lose their normal shape. I'd really appreciate any answers or suggestions.

the problem is in mobile/tablet views in general, not just iOS.
Remove min width and height from image and add
.quote,
.glasses {
width: 100%;
}

I have a photoshop file with 8 concentric 'rings' (although some aren't rings and are more irregular), with the largest at the 'back' and decreasing in size up to the 8th one being very small in the centre.
The 'rings' are drawn in such a way as that the smaller ones are 'internal' to its 'outer' or next larger ring. Each 'ring' has transparency on its outside, but also on its inside (where the smaller rings would 'sit').
I need to support all iOS devices (Universal App).
The largest image has a default size of 2048x2048 pixels, but every one of the 8 layers has a common 'centre' point around which they need to rotate, and around which they need to be fixed.
So, basically, all 8 have to be layered, one on top of the other, such that their centres are all perfectly aligned.
BUT the size of the artwork is larger than any iOS device, and the auto-layout has to allow for every device size and orientation, with the largest (rear) layer having an 8 point inset from the screen edges.
For those that can't picture this, here is a crude representation, where the dark background is 'transparent' and represents the smaller of the width or height of the iOS device (depending on orientation):
Note: The placement of where each smaller UIImageView is precise. They all share a common centre (the centre of the screen) but each ring sits 'inside' of the larger ring behind it. i.e. the centre of the green, hot pink and baby pink circles are empty / transparent, and no matter what size screen or orientations, they have to nest together perfectly, as they do in the photoshop art assets.
I've spent hours in auto-layout trying to sort this out, and when I've got it working on one device and both orientations, it's not working on any others.
No code to show because I'm trying to do this in IB so I can preview on all devices.
Is this even possible using IB / Auto-Layout or do I have to switch to manually working out the scales by which to resize their UIImageView based on screen width / height at runtime and the relationship between each 'ring'?
Edit:
And unless I'm doing it wrong, embedding each UIImageView into a transparent UIView in order to use the UIView to fake 'insets', this doesn't work because those numbers are hard coded, such that when it's perfect on a 12.9" iPad Pro, on an iPhone SE each 'inset' UIImageView is much more compressed and doesn't sit 'inside' it's next larger ring, but is like a tiny letter O with lots of surrounding blank space, because those 'insets' don't scale. What is 100pts on an iPad is a tiny amount of space, but 100pts on an iPhone SE is a 1/3 of the screen.
You can draw circles using CAShapeLayer and UIBezierPath. Since you are trying to fit this in a square, I'd define container size to be either the width or height of the parent container depending on what's smaller, this will allow for rotation and different screen sizes. As for the center, you can always find it by getting center coordinates of your square container (container.bounds.size.width / 2). To rotate your layers/sublayers you can use this answer: https://stackoverflow.com/a/3929703/4577610
In portrait I am having two images in the corners one is on the left top and the another on the bottom right.When I rotate the two images stays in the same corner.But I need the whole portrait screen to be rotate left by 90 degree. Here is the images
1) Image 1
2) Image 2
Though i have tried using constraints and auto layout to fix the images but failed.
Need help thanks in advance.
If I understand well your question:
You should look at Size Classes. You can design different layouts and button arrangements in storyboard using the different size classes. You can watch 2min 30sec of the Stanford iOS8 course about Size Classes here, that can give you a quick intro on the topic.
You can simply Do it through Size Classes!!!

I'm making my first iphone game using swift/xcode with gimp to draw the graphics. I'm having trouble understanding what size I should make the image in gimp to use it for the background of my iphone game.
The various devices have different screen sizes, so presumably you will want your image to adapt. Thus it really isn't about your image but about the image view that will display it (assuming you're using an image view). The things to think about are:
How to use constraints to pin the edges of the UIImageView to the edges of the screen.
How to set the content mode of the UIImageView so that it displays the image acceptably on all device sizes.
I am creating an Ipad app and no matter what height I set my ImageView to be it is always too big.
For example I have an ImageView that's about 20 pixels tall and has all of the constraints that I need to keep it where I want it to be. When I play this 20 pixel tall ImageView on the Ipad simulator the ImageView covers about half of the Ipad screen.
How can I work with Ipad images if even a 1x1 pixel image view takes up a signifiant amount of the screen? (Yes, I made the 1x1 image just to see if it would still be insanely large)
Under Auto Layout, if you don't set the size of the image view absolutely, it will size itself to match the size of the image assigned to it. That is probably what is happening to you.
I am developing a universal app for iOS-7. this particular question is specific to iPad only. I want to place an image as background of root view of a View Controller i.e. the image should fill the whole screen. The 1x image has size:768x1024. This works for Portrait orientations as non-retina resolution of iPad is also 768x1024 in portrait. In Landscape however the image does not fit. I have tried using ScaleToFit but since aspect ratio of image is not preserved I can not use ScaleToFit(their are things in image which look odd when not scaled proportionally in both axis). AspectFill resizing seems most suitable for my need, but their is a small problem. As defined in Apple Documentation "The content is resized to completely fill the bounds rectangle, while still preserving the aspect of the content. The content is centered in the axis it exceeds.". I do not want the content to be centered in axis in which it exceeds, I want it to be aligned to top/left edge.
So basically I want two things:
Aspect Fill
The content remains aligned on the Left/Top edge.
Is it possible to achieve this. Any code-snippet will be great.
Thanks
You will have to subclass the View Controller's view and manually scale and align.
Look at the code snippets in THIS answer.
Adjust imageViewXOrigin and imageViewYOrigin to align however you want.
Really the only way to get around the content fill mode is to have two different images, one for each orientation. I'd suggest changing the image in the view controllers willAnimateToOrientation: method so that you can put the image changes inside UIKit's animation block.
