The model you are mentioning seems a lot like multiple users accessing a
database on a remote server.
In this analogy, the database is your document. The users accessing that one
database are the other apps that are accessing it.

But isn't it still true that many UI-oriented APIs can only be safely called on
the main thread, regardle

As I'm experimenting with how to implement pinch and rotate gestures in a
UIScrolLView, I set up a non-autolayout (traditional) pinch-zooming
UIScrollView with a UIImageView inside it.
I followed the instructions here:

The Apple Maps application allows you to pan, zoom, and rotate in a single
two-finger gesture.
Is that done with three gesture recognizers all operating simultaneously? Or
are they just handling the touches directly?
I don't see how to get a combined transform out of the three separate gesture
Isn't it a matter of implementing this delegate method?
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer
*)otherGestureRecognizer
{
return YES;
}

So, this sort of works, and fails spectacularly.
The problem is that I can't specify the order in which each gesture's values
are applied to the view's transform.
So, I end up with a side-to-side panning gesture making the image move
up-and-down when it's rotated about 90°.

Assuming you want to rotate about the center of the object, you probably want
to translate the object so it's center is at the origin, do the rotation, and
then do the inverse of the translation. If you do that, the order of the
recognizers shouldn't matter.

Developing a simple iOS app, I've run into a little misunderstanding about
First Responder.
On the Mac, the app's delegate gets messages intended for FR that reach
NSApplication, on iOS, that appears not to be the case.
My app needs a simple action method that can be accessed from two different
21 matches
