I'm working on this little Mac App using Swift. When the app detects a certain color, it should simulate a click on it.
I'm using a NSTimer that calls the function "searchForColor()" every second; and when the function detects the color within the app, it clicks it.
What would be the best way to approach this?

I am trying to make a alarm app where I want to display a popup and play a sound so that the user gets alarmed. I first found the System_Alert_Window module, but it looks like it lacks a bit of styling property. I can set the background color of the whole popup + I cant attach any image. So, is there any alternative to that module to draw over other apps?
I have seen some apps where when you launch them for the first time after downloading (e.g. Chrome app on iPhone), it shows you a list of animated gestures on the screen, kind of giving you a tour of the app.
How do I build one something like that? And how does the app know to launch only for the first time after download and not since then? For the second question, I am guessing a "shown=TRUE" value can be saved inside a PList file and checking the value each time when the app finished launching. But I am more curious about the mechanism involved in creating a guided app tour.
You can use transparent and semi-transparent images with a UIImageView, so you can make up an image with arrows and notes and put over the whole screen. You could fade it out when the user taps.
To know if it's the first time running the app, you should use NSUserDefaults instead of a plist; it's much easier, and you should be app to find a quick tutorial on that fairly easily.
Also, you could check around on this site for controls like this one. I haven't used any of them myself, so I'm not sure how much they differ from a regular UIImageView. They look nice though.
I am writing an API in C++ Builder that collects information for events on the touchpad of a windows laptop.
This is how I was doing it.
I was creating a window
when the touch pad is touched, I simply paint that information on that window in WM_PAINT event.
But now I dont want to create that window (form), i want to catch all the events, even if user is on desktop screen or on another application's window. If an application that is using my API is running in background i want to be able to get that touch even information in the code. How can I do that??
I hope you are getting my point ... actually i want to do it in a seamless way, otherwise that white form window will irritate the user.
I also want to save these events in a link list and want to return that out of the API is it possible??
I will be very thankful for your time. I really need to work it out in next few hours.
The touchpad is just a mouse like any other. It generates standard mouse events. Use a global WH_MOUSE hook via SetWindowsHookEx() to capture mouse events globally. To replay them, use mouse_event(). Alternatively, use WH_JOURNALRECORD and WH_JOURNALPLAYBACK hooks instead for capture and playback, respectively.
I want to make the thumb of my slider to work as the button so that when a user done selecting the value and pull his finger up it should do something i want.
Is there any way to do this.
Thanks,
Hi,
Create this function
- (IBAction)mySliderUserFinshed:(UISlider *)theSlider
Make sure you add it to the header of you file.
The in interface builder, right click on the slider you want to act as a button.
You will need to wire up the Sent Event
Touch Up Inside to the function that you created. If you dont know how to use interface builder watch a few quick videos on youtube or in Xcode 4 there is a short guide on some of the new and awesome features of xCode 4 with very very cool videos (takes about 10mins to watch and will save you hours of coding).
Good Luck, John.
Hello I'm trying to get the multitasking work properly, but unfortunately I'm kinda lost. My problem is when I re-enter the game, it takes several seconds for the game to come back and show the pause screen. My question is; is there any way to put some sort of loading screen until the game comes back, so I can at least indicate that its not frozen? I've never used Xcode directly. I'm using Unity 3d to build my game. I made a little bit of research and if I'm not mistaken I'm supposed to use "applicationDidEnterBackground" app delegate method. My question is How can I put a custom loading screen using that method in Xcode?
Thanks
In -applicationDidEnterBackground:, you're given the opportunity to "clean up" the UI before the screenshot is taken. Apple says you should remove "sensitive data" (the screenshots might be persisted to "disk"?), but it also lets you do other things. In one app, we hide the label on a countdown timer so it doesn't appear to jump when you switch back to the app.
To change the "loading screen", simply display a full-screen view over the other views and remove it in -applicationWillEnterForeground:. Alternatively, pause the game in the first place!
(Really, you should be pausing the game in -applicationWillResignActive: which happens when the user double-taps home or the user receives a SMS/notification. I'm pretty sure it's called when the app is backgrounded, too.)
