I want to make a menu with a wide image that scrolls horizontally (it's a continuous image). What technique could I use for this?
Thanks!
The standard way to do this is to create a NSScrollView and nest a NSImage in it. You could run into problems if your continuous image is too large, however. In that case you'd want to split it into multiple NSImages and arrange them next to each other in the NSScrollView.

My app is a game and the menus have many labels and buttons and I cannot get all of the different screen sizes(iPhone 4/5/6/6+) to look acceptable from the same set of constraints.
Is there a way that you use to synchronize all the views together to look the same on all different screen sizes?
The project is locked to only portrait so I don't need to consider rotation.
For Autolayout, you
Consider the screen sizes you want to support.
Which view/buttons/labels/imageview etc you want to remain fixed while in
different screen size.
Which view/buttons/labels/imageview etc can be scaled to fit the screen.
Now if by scaling the things you can fit on the screen then you are good to go. But if you still can't find way then you would probably need to you use scrollview and and add a UIView (let's call it content view) to it put your all stuff in it and constraint them vertically all the way from top to bottom.This video can help you if you want to use scrollview

I designed my apps UI using Sketch. Is there a way to transfer it directly into Xcode ie the storyboard? Or do I have to recreate the design from scratch using Xcode's Storyboard?
I've done it in pieces using Sketches, a program similar to Sketch. I exported each drawing from Sketches as a JPEG and then added the file in Xcode. You might want to use some intermediary program (such as Preview) to change the size of the drawing to exactly whatever you need for the app. If you've created an entire drawing of the proposed screen, you can use it as the background for a screen-sized imageView. Then you can place the appropriate UI elements and re-size them to match. Delete the imageView. With Auto Layout, you can set it to use the Canvas values to generate constraints as needed.
I have one view filling the screen with a background image. Other views (text fields) are in exact positions (the background image includes the text field background images). When I change from 3.5" screen to 4", the text fields don't change in the same way that the background resizes. The bg image simply resizes to fill the screen, but the text fields jump out of alignment.
Is there a way to have two sets of constraints, one for each screen size? or is there a way to have views resize proportionally to another view?
EDIT:

size?
Yes, by adding constraints programatically and checking [[UIScreen mainScreen] bounds] to get the screen size.
or is there a way to have views resize proportionally to another view?
Yes, you could set this up in interface builder. But it will be hard to manage, I would manage the constraints manually in code since you are using a custom background image the textviews need to position exactly
You're going to struggle to get these things to line up properly with the text view backgrounds being part of the background image.
You should amend your image assets and use the background property of UITextField to have an actual background image, and remove the boxes from your main background image. The icons could be separate images as well.
Failing that, it would make more sense to have the image stretch underneath the text boxes rather than on top.
Your layout is doing what it should do based on your description, but the image isn't stretching in the right way. In your screenshots, username is always the same distance from the top, and the others are the same distance from the bottom, but that isn't how image stretching works. I don't know how you've set it up but it would make sense to have a single image the size of the 4 inch screen, which has the bottom cut off for 3.5 inch devices, and constrain everything from the top.
what i'm trying to do is displaying a set of images in a grid like fashion but with different sizes as for images in landscape or portrait position, this excludes using the NSCollectionView because the item prototype's size can only be set once...
i'd go and add subviews programmatically to a scrollView but this yet again when the window's size changes and the scrollView get a bigger width, there will be just blank spaces on the right side...
you can checkout the image below for a better understanding...

thanks in advance you guys...
what i ended up doing was implementing a purely mathematic algorithm where i calculated the (x,y) position for every new added photo depending on the previously added photos and it did a pretty good job... the container holding the photos was embedded in a scrollView, needless to say that i had to calculate the height of this container as well.
I have a NSView that houses about a dozen WebViews populated with HTML generated from the application. When I first init them, I wait for - (void)webView:didFinishLoadForFrame: to fire before laying them out and adding them to the view based on the documentView frame.
How would I go about resizing these WebViews along with the window? Is there a way to get the desired size of the WebView for a given width?
Since all you're using the web views for is rendering MarkDown, you should instead investigate MacDown or MarkdownLive. These render MarkDown directly into an NSTextView. This will be MUCH more efficient than multiple WebView objects.
In future, you should ensure that your question includes what you're actually trying to achieve because there's often a simpler way to do what you want than the way you think it perhaps should be achieved.
