how to change layout on orientation change for titanium ipad - ipad

I'm trying to make a spec on the ipad for an image gallery that has a 3x3 portrait layout but changes to a 3x2 layout on landscape.
I'm trying to get the landscape or portrait grid on application load and then change also on orientation change but every time I do change my orientation the thumbnails flicker and the grid is all out of wack.

I'm thinking 'clear out or reset' the view, is there way to do that?

I've done similar with Windows, rather than views - my approach was to .close() then .open() again, suited my needs, might be worth investigating with yours

Existing app needs UIScrollView when using Size Classes

I have an iPad app that is written for Portrait mode; I am trying to add Landscape mode to it using Auto Layout. Everything appears to work just by changing the Size Classes in XCode, except some of the pages are longer when displayed in Landscape mode. My thoughts are to just add a UIScrollView to each page that needs it, at the top of the view hierarchy.
Is this the preferred method of solving this issue?
Yes, when designing an app for both landscape and portrait orientations you usually will need to make the content scrollable in landscape orientation.
You can also create a different layout for the landscape orientation and completely re-layout the UI components when the app rotates, but for simplicity putting all of your objects in a scroll view will solve your issue of limited real estate on the screen.

Disable landscape orientation for iPhone only using size classes

I am using adaptive layout with size classes (iOS10).
For an iPad I want to support portrait & landscape views, but for iPhone I only want to support portrait. I don't want to rotate screen for compact height.
iPad is all fine and I have set-up the iPhone views using size classes, so I am thinking I need to somehow detect what size class will be transitioned to and disable rotation if it would go to compact height.
I can see a method called traitCollectionDidChange, but not sure if this is the correct time in the lifecycle to detect this.
There are a few related questions, but I don't see anything that covers this specific scenario.

Appropriate way to manage different views for portrait and landscape?

I'm developing an app targeting iOS 7 and above. I'm using storyboard and autolayout, and I have to show different layouts of each storyboard scene depending on the device orientation, I mean, for example: in portrait I may have a button at a certain place that has to be shown in another place in landscape, or I may have controls in portrait that should disappear in landscape and have to rearrange the rest of controls.
My question is: when there are a lot of differences between portrait and landscape, should it be better to manage all this changes by programmatically updating constraints, or should it be better to create different nib files and load the corresponding according to the orientation?
use size classes their will be no problem in giving support to ios7 . I have tested their were no major problems in ios7 while using size classes.

UIViewController Size doesn´t work

Hi im currently developing an Universal app for iPhone, iPod and iPad. I have all view controllers in both storyboards set to Inferred. It works fine on iPhone Retina and on all iPads but when you put it in landscape mode it gets all messed upp and on the iphone 3,5 inch simulator the bottom gets cut off. How can i fix this? Do i have do create seperate view controllers for landscape mode and iphone 3,5? And the write some code that recognizes if its in landscape mode and iphone 4? I thought this worked automatically. Or have i done something wrong?
There is no quick fix/answer to your question.
Since the screen size is different while using horizontal and vertical orientations - it is simply not the same canvas and thus you will need to do some manual work to set it right.
Strategy 1.
Assuming your layout is simple - there are not too many elements and all elements can theoretically fit both horizontal and vertical screen size:
You should use auto layout from the Interface builder - Look at an excellent video from WWDC
https://developer.apple.com/wwdc/videos/
(video 406 - Taking Control of Auto Layout in Xcode 5)
In few words - you set spacers to your elements, aligning them to the end of your view (dynamically), therefore you can make your element shrink and move automatically respecting the current screen orientation.
Strategy 2.
Assuming your UI is complex and will not fit both orientations:
have a different xib file for horizontal and vertical views, this can take some time, but it is a solid solution that always looks good.
You simply need to track changes in orientation and load the appropriate xib.
Your problem will only be solved if you use Autolayouting and for that you need to go through some tutorials
Ray's Tutorial
Another Very well explained tutorial
Going through the above articles will definately help you in solving your problem

IPad orientation support like home screen application icons

How to make a view with 3x4 thumb ImageViews in portrait mode and 4x3 thumb ImageViews in landscape orientation exactly that looks like
The orientation effect in iPad home screen icons change/animation effect from landscape to portrait vice verse..I have gone through the app (https://github.com/jarada/myLauncher) but it has the effect that it looks like going to set the frames every time device rotates.
Guide me how to design it a sample tutorial link
You can use UICollectionViewController, adjust its layout to return the desired sizes & locations for your icons.
This tutorial can help you create a custom UICollectioViewLayout.
Hope it helps.
