Normally we can set animation to shapes. However, when these images are put in group, all the animation is lost. Is there a way to keep the animation of each shapes in a group?
The only way I know of (and it works for me) is to animate each one of them after they are grouped.

Is there a way to check when a SKSpriteNode / SKNode is onscreen (i.e. visible) I have a large scrolling background where I am spawning mobs, but I want to limit their animations and sounds if they are not visible. Is there a way to do this, I could write something in the update loop but I wanted to see if there was anything I could test before I start querying mob positions every frame?
I think you are doing this wrong. You should stick to the MVC pattern. As such, you only have data/points that are moving in a large area and in update method, if any data is within screen area, only would you draw them. If it is out, remove them.
I made a prototype for an app, just as a proof of concept to test whether the functionality is working properly or not. Now that I am satisfied with the working functionality, I want to paste the images I placed in a UIView into a UIScrollView, so that I can show data in different pages. But, as I select the elements and paste it in a scrollview, all the positions are lost, and I have to manually place the elements in the interface builder.
Check out this image, I have these many elements that I need to paste inside the UIScrollView.
Is there a better way of doing this? or do I have to manually place the elements in positions I want?
Thanks!
If you want to avoid the headache of repostioning of controls in IB, then try the following option
1) Take one more UIView.
2) Add the UIScrollView into the UIView.
3) Add your current UIView(view which you shown in question) into the UIScrollView.
Thanks.
Select all your children, then Menu/editor/embed in scroll view.
Et voilà !
How would I go about setting a custom background image for a UITableView. The wrench in the works is that the table is a grouped style (rounded top corners for the first cell and rounded bottom corners for the last cell). I would like do this as much in code as possible without relying on images too much.
Ideally, here is the solution, but I have no idea if this will work or not:
Create one custom background image
Apply the same custom background image to every cell
Rounding occurs automatically because it is a Grouped table style
Profit.
Is this how it works (besides the profit part... I am an app developer, after all)? Do I need to re-think my approach or is this possible? How would do what I described (or another approach) in code specific to iOS 5+?
Update
Just to clarify a bit, the main question I'm asking is: Does the rounding still occur on the top and bottom cells even if you are using a rectangular image?
Well I think what you are saying is ok, but I suggest creating a unique cell layout in a .nib file and apply there the background. Then, with initWithNibName you can manage every cell at the UITableView's methods on the ViewController.
I programmatically copy the shapes of an entire slide to a new slide in another presentation by performing origShape.Copy and then newSlide.Shapes.Paste().
(copy/paste the entire slide is unfortunately not an option for me here)
My problem is that Animation effects get really warped. Some are lost, others appear in the wrong order.
I thought that maybe after copying all the shapes I'll go over origSlide.TimeLine and will copy each animation effect to newSlide.TimeLine with the corresponding Shapes.
Is there a way of copying Animation effects between shapes without manually setting each and every parameter? (there are LOTS of these).
When copying shape-by-shape to a new slide, naturally the order of the animations gets ruined.
If we had for example the following animation sequence:
Rectangle flying in
Triangle flying in
Rectangle flying out
And we copy first the Rectangle and then the Triangle to a new slide, we'll get first both animations of the rectangle and then of the triangle.
My mistake was trying to solve this disorder by using Shape.AnimationSettings.
BEWARE OF SHAPE.ANIMATIONSETTINGS!!
This Property is kept only for backward compatibility with old versions of PowerPoint. If you modify any of its fields, all animations of a shape except the first one get AUTOMATICALLY ERASED !
So, the solution is this:
Copy shape by shape to new slide (no animations are lost, just mis-ordered). Then use Slide.TimeLine to go over the animation Effects and order them correctly using Effect.MoveTo, or Sequence.Clone and Effect.Delete.
Is there a simple way of animating rows in an NSTableView?
I'd like to be able to do something like flash a row, or fade out a row.
Essentially - to provide a bit of visual feedback when rows are added or removed.
Edited to add:
I'd had a quick look over Google before posting this; but I wanted to know if there was some way to do this that I'd missed other than drawing and animating parts of the table view myself.
To flash a row, there are a number of ways to go. You could just grab a cell and play with it's view, such as change the color of the background or font colors. You could also just select the cell and deselect it a few times, if you don't care about removing the existing selection from another cell. Or you could superimpose another view on top of the cell's view and use blend modes...
For animating the deletion, you could do the same as above, dimming the cell, or even move the view up and out, transform it so it shrinks down and move it over to a trash can and shrink it all the way down as it enters the trash. Then after the animation is done, you delete the row.
