I am using a pivot control in my wp7 application. I am displating some photos. I need to stop right flip when the last photo is displaying. Also stop left flip when First photo is displaying. How can I disable flip in one direction?
There is no way to disable this behaviour with the default control.
You should be very wary of disabling this functionality. This is the behaviour that users familiar with other apps on the phone will expect the app to work/behave.
If you must have this functionality then you'll have to create a suitable control yourself.

I am making an application that works essentially like a simple Drag-and-Drop Playground with the command blocks on the left and a droppable area on the right. I want to make it fully compatible with VoiceOver and I'm running into trouble with some of the accessibility aspects since this is my first Swift application.
This is what the playground currently looks like: (App Screenshot)
My goal is to provide the users with audio cues/feedback while they are dragging the elements to help them figure out what part of the screen they are currently at. The ideal functionality would be exactly like what one uses when editing an iOS device's Home screen (the arrangement layout of the apps).
When trying to rearrange apps on the home screen with VoiceOver enabled, you hear a row/column alert when you are dragging an app over an open area. I want a similar type of feedback that says "Droppable Area" when you are over the correct area (see scenario 1).
When trying to rearrange apps on the home screen with VoiceOver enabled, you hear a sound when you tap on an area that has no app icon. (This also happens when you are not editing the layout and simply tap on an open area with no app.) I want that noise to be what you hear when you drag a command over an area that is not droppable (see scenario 2).
Any ideas on how this might be possible or good references to look at?
When an app is running in a third of an iPad screen, there is a small drag handle at the top of its window. In iOS 10, dragging on that handle lets you switch what app is open there. In iOS 11, you can use it to change the app from taking up a third of the screen to floating over the rest of the screen.
My question: how do I know when this handle is present, or at least know that there's something taking up that space? I need to lay out my UI content around it without conflicting with it. It doesn't appear to work with iOS 11's Safe Area APIs.
See here for a sample project trying to put a label at the top of a window without overlaying the drag handle. Run it in a third of an iPad screen.
Start by duplicating the radar. This is definitely something that should be handled by the safe area magic.
The issue here is that the handle is rendered by SpringBoard, so you can only apply tricks to guess whether it is currently visible. You can determine whether the window is at the right size and whether it is at the correct location on screen, and then add some extra safe area insets. This is normally ill-advised for several reasons, such as not knowing all cases where the handle appears, having to take into account left-to-right systems, etc., but in this case, the problem seems so egregious, I'm not sure I'd recommend leaving as is.
Edit
One more option is to see if UIWindow.safeAreaInsets returns a correct value. UINavigationController is able to deduce the safe area correctly, so it is hiding there somewhere.
There seems to be dozens of questions on how to deal with :hover event on the websites when viewed in iPad.
My question is different - I'm building a native iOS game and it would be really good if a user can compare two items side by side. On PC this can easily be done by displaying one item a mouse-over panel when mouse hovers over an inventory item. The main benefit of such panel is that it is easy to show and easy to close on PC.
What are my alternatives for displaying a transient, hover-like interaction panel in a native iOS app?
For iPad (not iPhone) a UIPopover is pretty close to what you want. If you want to support iPhone/iPod as well, there are third party popover libraries for those devices.
However, I'm not sure how this would do for comparing 2 items, since the system only displays 1 popover at a time.
This is really more like a map callout bubble. You could build your own callout bubble sort of interface yourself without a lot of work. When you tap on an item, it would display it's callout, and when you tap on it again, or tap outside all items/callouts, it would hide it. I've done something like that for a custom map system I built for a client and it wasn't that hard.
Hullo,
I have an app view rather crowded to insert the necessary switches in order to toggle 6 values associated to icons. So I would have appreciated if it were possible to make them sticky buttons, namely to have them independently keep the pressure when clicked in order for me to read the ones in that state when exiting the view.
I read there exists such a technique for Mac but that does not translate to iOS. Hw could I do that?
Thanks, Fabrizio
It sounds like you're looking for a checkbox functionality. Have the button change images when it's pressed, then use that to determine its state.
I'm on my phone so this took a bit, but here's a link to how to make a checkbox in objective-c What is the best way to make a UIButton checkbox?
Note that you don't need to use normal checkbox images.
I think I've seen some implementations in flash, although I'm not sure.
On my ipad, through the photos app, you can open an album and scan through FULLSCREEN images using the flick to move it from side to side. My question is: can this be implemented through a website flipping through a album (collection of images)?
Thank you!
Here's something that might help:

It doesn't handle the mouse gestures, but shows one way to 'flip' full screen images.
To handle the 'flick' mouse gesture, you'd need to track mouse position and button states with event handlers & timers.
The "flipping" mechanism you're describing is called "cover flow" And there's a few implementations on the internets. The one I've heard recommended the most is http://xflow.pwhitrow.com/
