I'm trying to load a large version of an image in the centre of the user's screen when then tap on a smaller version of the image that's already on my view.
Ideally I want to do this using an animation to get to the new image like a vertical flip.
Also if there's a way to make the background look greyed out like it's not the foreground then that would be even better.
Here's an image of what I'm after, I'm at work at the moment so haven't got access to the actual code / images.
I'm a new user so can't add pictures. Click here if you want to see what I'm thinking.

There is an KGmodal Example Exist in GitHUB hope that Might Help you.
You have to Change the content view and Add an Imageview Programatically (with required size ) in the content View.
Follow the below link: https://github.com/kgn/KGModal
For Fliping the image see the tutorial iphone Flip Image.
In the end I added the larger image on to begin with and set its alpha to 0, then added a gesture recognizer on the smaller image that animated the larger one and gradually changed its alpha to 1. The did the reverse on the large image. Don't know why I didn't think of that in the first place!

As the title suggests, Is there a way to set and update the background image in blender 2.8 2d animation workspace? I mean it's easy enough to add a background by dragging the image onto the viewport but then I can't seem to interact with it at all or change it to a different image.
Just to point out it's fairly easy to change background in a 3d project. What I'm asking for is updating the background image in a 2d project. I want this for a reference image.
Thanks!
2.80 no longer has "background images" like previous versions.
The Add->Image->Reference actually adds an empty that is set to display as an image. You can set the empties properties to adjust the display options which includes the image displayed, you can also move it around like any other object.
There is also now a background image settings for camera objects, this looks like the old background image settings, but is part of the camera settings and is only visible in camera view.
below i attached an app help guide screen. I am understanding how to build this screen.
If any body have idea please share here
View with semi transparent background color (backgroundColor:"rgba(0,0,0,0.5)";) and some images on top of it.
So, using images is bad. You'll need images for translations and if you do this as one image you'll need to ensure all devices are covered so your arrows point to the right element.
Minimise images == smaller app.
First thing you'll need to do is a create a blocker view -- so that's a view that will fill the screen and have a black background with opacity.
You can't apply that to the window as everything in it will be semi-transparent so:
Create a transparent Window that fills the screen.
Add to that window a view that fills the window and has opacity say 0.5 and black background
Add to the Window (not the view you just created) the other elements and button -- ideally, these should be individual graphics of the arrows, sized in such a way that you can position them based on the host element (the item they are pointing to / referring to). Use real text so you can handle translations / reduce file size.
So you'll need a way to associate each tip with a control they are anchored too, and that will ensure that regardless of the screen size, the tip will appear in the correct place.
First of all, always give a try before putting questions anywhere because it makes you learn things on your own for long time.
The easiest step for you to do this is to ask your designer to create a complete image just like that & you just have to show it on top.
If you have to show that image in different translations, then you can ask your designer to provide you required translations images.
In my project I am using segmented control with 3 segments. I have picture for every segment and pressed/unpressed state. Here is image:

If picture size is not matching segment size then it not fits. Is there any solution for this problem?
Thanks
If you're using iOS 5 or later, you can use UIImage's resizableImageWithCapInsets: method to create resizable buttons for your segmented control and then just render your text on top of it. A good tutorial on this is available here.
Essentially, all you have to do is create versions of your button images that have distinct ends and centers that can be resized.
Use - (UIImage *)resizableImageWithCapInsets:(UIEdgeInsets)capInsets method of UIImage for setting image to your button. It will return you resized image for your button. Available in iOS 5.0 and later.
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 the case:
I have an image. In the projects browser it looks good.
/but when I 'load' it in one of my controls the edges get rather blurry. And I'm not resizing it or anything. Why is this?
The image, unloaded:
The image when loaded in a control:
As you can see the corners get rather blurry/streched. Why?
It happened to me in the past.
Most of the time the problem is that the dimensions of the image are different from the dimensions of the controller.
Check you controller size with:
NSLog(#"controller size = %#",NSStringFromRect(your_controller.rect));
And see if it the image size fits.
I've also had this before and as #shannoga said if the dimensions of the view are different to the image it will auto stretch it.
Are you loading the image into an ImageView? if so the imageView.Mode property defaults to Scale To Fill. If you set the mode to Top, Left or Center it wont stretch the image.
