I have a screen in Corona to display a puzzle, and once user guess the correct answer, I'm going to display a simple pop up on the screen to do the congratulation a long with close button to dismiss the popup, now I need for a simple work around to disable any control or behaviour on the original screen while displaying the popup, how can I do that?
I think you need to do this by stop or pause transitions, timers and animations etc. before you go to scene with pop up.
You can add transparent rectangle from transparent image file (not just rectangle, as it will not be touchable).
Size of this rectangle must be the size of all screen.
Position of rectangle - under your popup (or better make it as part of your popup).
Add listeners to this rectangle on touch and tap that will just return false - so it will prevent any clicks under it.
That will save you from pausing / disabling buttons, that you don't want to disable/pause.

I am trying to implement a slider in the known slide to unlock style from older iphones to perform an action inside my swift app. The Slider should change background color and change the text inside while dragging. When the user drags til the end, the thumbView should stick to the right side and wait for a confirmation (some event) coming in to finally present a new view.
The slider should look something like this:
First state
Second state while dragging
Third state after releasing
I have found a few things on the internet but nothing that comes close to what I want to do. How would I go about doing this? My guess would be a combination of views with drag events but I feel like there must be an easier way. Any Ideas?
Maybe a UISlider with a transparent track on a rectangle view with your text and color. You can set your image as the UISlider's thumb and receive events as the value changes and when the user touches and releases it.
You can use that to for example, animate the thumb back to the start when the user releases on any place except the end of the track. Also, you can set the slider's value from 0 to 1 and use it to calculate the color, so it changes smoothly.
When the user releases on the end of the track, you activate the activity indicator and start your process to present the next view....
Even though this is a possibility, I think I'd try doing a custom control using a pan gesture. It'd give you more control and you could for example choose how the thumb image animates when going back to the start on release.... I dont' think you can do that with UISlider's setValue(animated:).
There is a simple button in our application which when is pressed works just as expected, but with a light quick touch it just greys out and does nothing.
Is there a way to capture those light touches too?
EDIT:
I see now when exactly it doesn't work and it is when I tap, drag and release. (even if I tap, drag and don't leave the button area)
Try setting EventSystem.pixelDragThreshold to a higher value. This threshold makes the difference between a click and a drag, and it's default value is quite low for high-res touch systems.
What I want to do, is whenever the user clicks anywhere on the screen, a shadow or an instance of a shadow is created wherever they click for as long as they click. Like having an app that has a white background but whenever you press the screen a black dot appears under your finger and follows it but when you take your finger off it disappears.
To handle touch events, here's a great guide on UIGestureRecognizers on Raywenderlich.
As for the black dot that you described, you could try drawing it with CoreGraphics.
I've been searching and searching on how apple makes the dragging motion on the lock screen to open the camera so clean. I'm trying to do a similar thing with an app where you drag from the bottom up to reveal a menu, but i cant quite get it right. Anyone know how to, or of any tutorials that show how to do this? Thanks in advance!
To follow up what's been mentioned by Hejazi I believe you can achieve this in 3 steps:
create a background rectangle with some corner radius (this is a property of CGRect).
create a top view, corresponding to the part you want to be able to slide. Attach a pan gesture to this view so you will be able to handle the animation for this view.
for the text part being highlighted I think you need another two views: I will apply a mask corresponding to the text to a view so you get some transparency only for the letters of your text and animate a white round view behind it.
I have an arrow button that I want to keep small but I want the touch area around it to be bigger.
I used the answer from the post Here but it made my button larger.
The problem is that the picture of the button is larger than the size it is presented in. But I thought there must be a way to do it without editing it or adding a transparent button.
Use a custom button with an image with mode "center"(which means that it doesn't resize with the button size and stays always in the center). Then you can make the button as big as you want and the button image always stays in the middle with the same size.
You should be able to do it by extending the button class and overriding the hitTest method. In your version of this method you can expand the area checked to include a buffer area and return the button if the touch happens within it.
A transparent button behind this button would also work and just point that to the method... I suppose you could go about this multiple ways. One should prefer the option that is simplest with the least overhead.
