Is it possible using the SDK to change the bluetooth headset/remote buttons behavior. I would like to capture the button press(es) and perform some action, eg, skip next track, launch popup etc
I think you will receive appropriate callbacks from iOS when a button is pressed, and within these callbacks you can decide what to do.

I’m quite new to swiftui and I was curious on what’s the difference between using a button displaying an image or an image with onTapGesture modifier that make an action just like the action on buttons.
In the use case you've described you can use either but for reference, Apple provides the following guidance in their documentation for onTapGesture:
If you are creating a control that’s functionally equivalent to a Button, use ButtonStyle to create a customized button instead.
onTapGesture adds an action to perform when the view recognizes a tap gesture and can be tailored to respond to any number of taps (with 1 being the default).
Buttons are a control that performs an action when triggered and have the benefit of automatically adapting their visual style to match the expected style within different containers and contexts.
In iOS and watchOS, the user triggers a standard button by tapping on it.
In macOS, the user triggers a standard button by clicking on it.
In tvOS, the user triggers a standard button by pressing “select” on an external remote, like the Siri Remote, while focusing on the button.
For more information please refer to Apples documentation here: https://developer.apple.com/documentation/swiftui/text/ontapgesture(count:perform:)

I would recommend using Button when you want the feature of a button. I noticed that images cannot be used as buttons with Voice Over on. When I changed those to use Button instead, it fixes the problem.
I am making an Apple TV game and am programming the settings screens. The problem I am running into is that the Nimbus gamepad is sending multiple button pressed messages when I press the button just once. I would really appreciate it if someone could tell me if there is a way to make the controller send only one button tapped message when the button is tapped just once. I mean I would like it is there was a way to have only one message generated after I press a button and release the button. Thanks very much.
Looking at the GameController docs:
https://developer.apple.com/documentation/gamecontroller/gccontrollerbuttoninput?changes=_2
Are you using pressedChangedHandler or valueChangedHandler? IIRC, the Nimbus has pressure-sensitive buttons so you should expect to receive continuously changing values when the button is pressed or released. pressedChangedHandler should only be called when isPressed is toggled.
i'm trying to manage different state of a simple push button on an OS X application : When the user click on it, and when the user release the click.
Currently i set my button type by NSMomentaryLightButton
NSMomentaryLightButton When the button is clicked (on state), it
appears illuminated. If the button has borders, it may also appear
recessed. When the button is released, it returns to its normal (off)
state.
This type of button is best for simply triggering actions because it
doesn’t show its state; it always displays its normal image or title.
This option is called Momentary Light in Interface Builder’s Button
inspector
I thought it was the good way, but when i print my button status, it's like a toggle button than the push button that i set. As you can see on exemple gif
To sum up, How can i have a real push button behaviour ? Call function when the user click on it, and when the user release the click.
Thank,
You don't want to use buttons for piano keys. First, they are non-rectangular, and they don't act as buttons do: neither single-action push-button, nor toggle switches. You are interacting in a custom way, with a custom view, meaning the NSButton control hierarchy isn't called for. Instead you're subclassing NSView and capturing low-level mouse events as detailed here:
https://developer.apple.com/library/prerelease/content/documentation/Cocoa/Conceptual/EventOverview/HandlingMouseEvents/HandlingMouseEvents.html#//apple_ref/doc/uid/10000060i-CH6-SW1
You found this yourself as you detailed in your own comments, but I wanted to make sure you had a higher level point of view. It's even possible, and probably best, to consolidate all of the piano keys into a single view, and let the keys themselves be rendered using NSBezierPath and perform mouse hit detection using containsPoint:
https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSBezierPath_Class/#//apple_ref/occ/instm/NSBezierPath/containsPoint:
This is a lot more work but the only way to make a truly professional looking piano simulation. Then you can render the keys with whatever outline, fill, and labeling you need without the limitations of built-in button shapes and layout. You could even have the bottom edges of the keys slightly rounded, for example, or apply a shiny texture.
On this site : mecanomedic.com, the menu template work fine in "normal" desktop browser, but dont slide down on ipad-iphone device. What can be the problem ?
Some tell me it's a css problem, but HOW safari desktop work ?
The problem is that the menu expansion relies on the user hovering with a mouse. On touch devices like iPads & iPhones, the hovering gesture can't be replicated because there's only one input- touch. If I were you, I'd take a look at Twitter's Bootstrap menu setup and perhaps use media queries to serve up a different menu on smaller screen sizes.
Here's an example of a Bootstrap navigation bar in action (you'll have to inspect the code to see how it works).
Add a href to the top-level <a>'s so that they can be focusable:
Produits
Elements that are focusable receive mouse events and hover styles when the user taps on them.
As #Matt stated, the problem is that your menu relies on a hover event and unfortunately that event is unavailable on touch screen devices.
One way to fix this would be to:
Check if the current user's device is an iOS device
If the device is an iOS device, use javascript to trigger a menu item's "show event" when the menu button is CLICKED instead of ROLLED OVER / HOVERED.
This would result in the menu being shown when the user taps a menu button.
while i am doing program i got dbt how to write the code for radio button
As Ranjeet says, there is no radio button.
You can used segmented control, switch or button depending on the aim.
iphone does not support radiobutton...
I mean this feature has not present here...
You have to make your tricks(alternates)...
like show and hide images...and some more
