Im writing a report with Reporting services that is almost always only going to be used as exported to PDF, but the PDFs i get are always in Landscape mode and i want them in Portrait (but only for this report)
Is there a way to change it between these pages layouts?
To change my reports to landscape, I simply swap the "PageSize" property's Height and Width values on the report itself. If I make the width 29.7cm and the height 21cm, I get a landscape report. The other way around is portrait.
Reports are portrait by default though - if yours are showing up as landscape and nobody has changed the height and width of the page, then I'm not sure what's happening.

I'm using Sketch to create images that will be used in my Xcode 6 auto-layout storyboards. However I can not get the image sizes correct. They always appear too large and overflow the storyboard view controller. Is there a way in Xcode to see the dimensions the storyboard expects? Is there a systematic way to do this...rather than trial and error?
Storyboard, especially in auto layout mode, doesn't expect any dimensions – dimensions will depend on device screen (in reality) or on simulated metrics (in Interface Builder in Xcode).
What matters is aspect ratio and presence of three resource files (three sizes – regular, 2x and 3x).
You can see the list of dimensions here:
http://www.paintcodeapp.com/news/iphone-6-screens-demystified
So, let's say you want to insert an image that occupies the whole width of the screen, and the height is chosen automatically so that to keep the aspect ratio. What you could do:
Create images in Sketch with widths of 320, 750 and 1242 pixels. Save them as image.png, image#2x.png, image#3x.png.
Insert image in Interface Builder (Storyboard), add width constraint – equal as superview, instead of height constraint – keep aspect ratio.
If the image looked too big, Interface Builder will complain that preview image doesn't match constraints, you will see a little yellow arrow. Click on it, choose the warning and click again – Xcode will offer you to "Update frame". That will resize the image correctly if necessary. Don't forget to choose correct scaling mode (Aspect fit?) for your image.
Moreover, you can see current width and height of the simulated screen in Metrics tab. But those will change every time you change your preview (simulated) device type.
I developed my whole app on Xcode 6. I use auto layout on an Universal Storyboard. During the whole development my Storyboard was in the any height/compact height size class.
Therefore, now that I'm testing on iPad, i have blank sheet. Same if I put my storyboard back on any width, any height mode, it's all blank.
I think it's linked to the size classes and my views are not implementing all the classes as I added them when I was working in any height/ compact width mode.
So is there any way to move my app back into the any height/any width class?
Thank you.
I have a view controller that consists of two child UIContainerViews, one of which is fixed-width, and the other which dynamically adjusts its width based on portrait vs landscape mode. Both contain UITableViews.
For some reason, if the screen loads in portrait orientation it renders fine. However if it loads in landscape and then rotates to portrait, the second (dynamic) table gets all screwy and thinks it's wider than it is/should be, letting you scroll it horizontally which it should not be doing.
The cells of the tableView all size properly and stick to the left side of this "too wide" tableView. However, if I color the background of the tableview pink, I can see the whole thing is extending into this too wide zone.
It's baffling me what's going on here. Shouldn't autolayout be the same regardless of which orientation the view controller was loaded as?
If I log the widths in a viewDidRotate... handler, everything appears to have the correct width, yet it's still rendering in this bizarre way.
Is there perhaps I way I can just force the container view to re-lay it self out?
Update: It is the contentSize of the tableView that is getting messed up. All the other widths are correct when logged, but the contentSize.width is way off. The good news is I can just manually set this back to what it should be and everything works great! However it doesn't answer the question as to why it's happening in the first place or what I'm doing wrong (if anything).
Here's a screenshot:
In order to force a UITableView to (re)calculate its content size, you may use layoutIfNeeded method. It traverses through the view hierarchy and lays out the subviews immediately, so content size is set properly.
Instead of setting the size manually, call this method for your table view.
I'm using a webview to display a PDF.
The webview displays the PDF at it's actual size which is a little smaller than the size of the webvieww itself, revealing the scroll view underneath it.
I've tried setting the Webview to opaque and setting it's background color to another color, which works fine and dandy in the simulator, but fails to change the color on the device. On the device it changes the color of the background of the view behind the scroll view, this can be seen when the PDF is pulled all the way down.
I've also tried setting all the UIView's backgrounds, by iterating through the subviews but to no avail.
I've updated a diagram to help illustrate which area I'd like to color.

You really shouldn't mess around with UIWebView's internals.
They can change anytime and your code might just crash on the next version of iOS.
If you need more control about pdf display, you might wanna take a look at other possibilities to show pdf, like using the CGPDFDrawPage* functions. Of course they are pretty low-level and it's a lot of work required until you can get fast page display, zooming, etc all right.
This is with reference to this thread How to make a pdf printout occupy the entire A4 page.
I am able to bring all the content into a single page, but even if I set the printer preferences to landscape format, it doesn't print it.
What could be the problem?
Are you setting the orientation attribute of the tag? That attribute controls the orientation of the page, and you should set it to landscape.
From the Seam documentation
orientation — The orientation of the
page. Valid values are portrait and
landscape. In landscape mode, the
height and width page size values are
reversed.
