How to detect double tap on previous track button of remote control on iPhone?
I'm able to detect double taps on view and button of app, but UNABLE to detect double tap on button in the Remote Control (previous button in multitasking bar)..
Thanks all
You cannot detect the touches of the OS itself, in your case the multitasking bar. You can only detect touches within the bounds of your app. When the multitasking bar is revealed by the user, your application calls the
- (void)applicationWillResignActive:(UIApplication *)application method

What does the word "tap" mean on mobile platform? I can see there is IsTapEnabled property on UI.Element(s), however I don't understand what kind of action is "tap". What is difference between "tap" and "pressed"?
Pressed event is published when you start touching a control (= your finger starts to touch the control on the screen).
Tap event is published after you release the touch from the control (= remove your finger from the screen). It's the equivalent of Clicked in desktop applications.
So I have a status bar app that launches a small popover in the form of an NSPanel that has transient behaviour. However occasionally if I open say the Dropbox popover and then open my apps popover the dropbox menu will not disappear until I click a button in my popover. Which is strange because it only happens sometimes, and I am using [window makeKeyAndOrderFront:self]; when opening the popover. It works with Skypes drop down menu as well as a host of other status bar applications. There are a couple that won't dismiss when I open mine until I make an interaction in my popover. Is there a way to set focus to that button or something in the panel that might help force the other menus to close all the time?
Im going to be using a framework that allows a iphone app to control my app on iPad. When i add it im going to make the joystick move a image of a mouse, and when the user presses the A button, i want to make the device think the user is touching at that point. Is there any way to do this?
Example: I place a button on the ipad screen at 0,0 with height and width of 100. then mouse is at point 50,50 and when the user presses and holds A, that button is held down, and when user lifts up, it calls that buttons action.
I am writing a Mac app that uses a window which is glued to the foreground of the screen. I am listening for the NSWindowDidResignKeyNotification to detect when it is appropriate to hide the window.
For almost every purpose -- including when a different application enters focus -- this works perfectly.
On OSX Lion there is an idiosyncrasy. When my window is open and glued to the foreground, and then the user selects the Launchpad icon from the dock to expand the Launchpad, my window stays in the foreground, even over Launchpad. It appears that Launchpad is implemented as some sort of screen overlay rather than a window that would take focus.
Does anyone have any solution to detect when Launchpad enters focus so that I can dismiss my window?
I'm developing a kiosk mode application for OSX. In some circumstances, another screen gets attached. My application runs in fullscreen on one screen using:
[self.window.contentView enterFullScreenMode:s
withOptions:[NSDictionary dictionaryWithObject:appOptions
forKey:NSFullScreenModeApplicationPresentationOptions]];
The options are the following:
[NSNumber numberWithUnsignedInt:(NSApplicationPresentationHideMenuBar|
NSApplicationPresentationHideDock|
NSApplicationPresentationDisableHideApplication|
NSApplicationPresentationDisableProcessSwitching|
NSApplicationPresentationDisableAppleMenu)];
What I want is limit the mouse cursor to the screen where the game is running.
How can I accomplish that?
Add an NSTrackingArea to the screens you don't want the mouse entering. When you get notified that the mouse has entered the tracking area, use CGEventCreateMouseEvent and CGPostEvent to move the mouse back to a safe location, probably the nearest point on the main screen.
