In Xcode I am having an issue with the size classes in my app. I am unable to get the right size classes to show that seem to work for all of my different devices. I kind of would like a key to see what the size classes should really be, also the size classes don't seem to really match up.
Below is an image attached of an example. I can't get anything correct. I am new to this and I know that I am doing something wrong.
Also, I tried this: https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/LayoutandAppearance.html but it didn't match up. Maybe my controls have a layout issue?
Edit: Shown below, I can't modify the leading edges and trailing edges...
Whoo Hooo!!! I figured it out!!! #nburk, I want to give you some credit too. You said the key words trailing space and leading space so I googled more on that, and I was seeing the wrong thing.
I want to recommend this to all users who are having problems with it. I didn't realize that dragging the constraints using the control button would actually do it.

In my program I have a bunch of RectangleFigures where each figure holds text. The text is held in a TextFlow which is held by FlowPage to allow word wrapping. RectangleFigure then uses getPrefferedSize() to make itself just big enough to hold it's text (using a fixed width).
These RectangleFigures are held by a ScalableLayeredPane. The problem rises when I try to zoom by calling setScale(). Most of the time it works fine but occasionally the ends of the text will be cut off. If I zoom again the figure will correct itself. I should also say that I have tested my program using Figure instead of RectangleFigure with the same result.
Has anyone dealt with this bug before and can shed some light on why this is happening and/or know of any workarounds?
I havn't included any code because this is a rather large program and relevant chunks of code are spread out. But if you would like to see the code let me know and I will try piecing it together.
I was holding the text inside a Figure and that was the Figure I was calling getPrefferedSize() on. But I then put that Figure(lets call it textFigure) inside a second Figure(called containerFigure). I was essentially doing the equivalent of containerFigure.setSize(textFigure.getPrefferedSize()).
You're probably wondering why I was doing that. Well originally I planned on having containerFigure hold multiple things instead of just textFigure. I ended up coding it differently but forgot about the unnecessary extra layer.
So even though containerFigure was technically the size it needed to be scaling caused problems. But when I removed containerFigure and started placing textFigure directly on the screen this bug was fixed.
This is a fairly specific error on my part so I don't know how much help this will be to others. To make it more broad if you're having some kind of sizing issue just check to see how the size of parent Figures are being set. Using sizes from child Figures might be incorrect and/or causing problems.
Note: I looked at the other questions similar to this one, and they were either outdated or not useful.
Unfortunately there are so many different screen sizes and that makes auto layout really confusing for me. I want to have a simple UIImageView to cover the entire screen no matter what screen size it is. So the dimensions of the UIImageView should change accordingly.
I tried adding constraints to squish the image and it worked fine. But an error in the debugger said that there was an error: UIViewAlertForUnsatisfiableConstraints
Is this a big deal? And if it is, how do I get the Image to fill the entire screen?
Edit: The game will have squares going down the screen, which the user must tap
It might be, or it might not be a big deal, depending on what you're doing and if you know what you're trying to accomplish. In my experience, this is usually an issue if you're trying to programmatically alter the frame of a view which already has set constraints (you shouldn't alter the frame by hand unless you really need it).
Without more detail, it's hard to say what the exact issue is.
The IE9 layout engine has issues with tables. Whitespace seems at the root of it.
If you've seen the infamous ghost cell you know what I'm talking about, if you haven't, consider yourself lucky and don't worry about it.
Anyways, I'd really like an HTML only sample to test "fixes" on.
I know I've seen it before in odd circumstances several layout tables deep, but I can no longer get the ghost cell to come up when I need it to.
What I need is a consistent ghost cell without invoking JS.
I've found several JS related ones, and there are plenty discussion on those when it comes to sorting.
This is a great sample:

I managed to clean up the html quite well and still keep the issue. I replaced all the javascript with equivalent spaces & newlines, and could remove most of the elements attributes without affecting the ghost-cell.
It seems like IE has a buffer problem since removing single spaces or newlines in a "safe area" cause the ghost cell to disappear, while removing entire attributes does not affect the rendering.
I see that you have unclosed tags, but I also managed to remove them altogether (replacing with spaces) without removing the ghost cell.
Result being I have a javascript-free html with ghost-cell. See result here: http://compscicon.no/ghostcell.htm
I know the idea is to make the text somehow hard to read for the users but still they complain and I've seen how the control used here in stackoverflow doesn't have the dark circles contrasting with the text in recaptcha.
How can I replicate this?
Thanks.
You can't.
If you want more control over how the CAPTCHAs are generated, you may want to take a look at different library.
In Latex how can you make the background image to occupy the whole sheet on every page except a certain stripe on the inner side of each page? I can't figure it out.
I have a background image I'd like to be seen in whole on each page after printing/binding.

There's some rather scary LaTeX hackery involving putting a picture environment under every page and using \includegraphics to put an image into that environment. You'll have to adjust the size of the image using the width option, and if you want even and odd pages you'll have to check the page number to know whether to shift the image right or left by changing \put(0,0) to \put(3,0) for example.
For page number testing try something on the order of
\ifodd\count0 ...stuff for odd-numbered pages ...
\else ... stuff for even-numbered pages ...
\fi
This isn't really a full answer but will be enough to get you started.
Honestly, I'd just add the white space in the image :)
Well, I was thinking of something like this.
Is this really so rare need to have? I myself need such a thing for the first time now but I don't feel it a so big oddity. It's strange for me that if you want a background to change over even and odd pages, just like normal text do, you need to feel betraying Latex logics. Or maybe I'm too fanatic of this challenge of mine and I want to feel the whole tex world change to fulfill my wishes. :)
Thank you for the answers!
