Create multiple UIViews when the user taps the screen


Create multiple UIViews when the user taps the screen

should help you out Assuming rectangle is a property, this code only changes the frame of the existing rectangle and re-adds it to the view hierarchy. If you want a new rectangle to be added each time the user begins touching the device, you have to create a new instance of UIView each time. For example:
code :
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    let touch = touches.anyObject()! as UITouch
    let location = touch.locationInView(self.view)

    println(location)

    let rectangle = UIView(frame: CGRectMake(location.x, location.y, 20, 20))
    rectangle.backgroundColor = UIColor.redColor()
    self.view.addSubview(rectangle)
}
let rectangle = UIView(frame: CGRectMake(0, 0, 20, 20))
rectangle.center = location
self.view.addSubview(rectangle)

I wish did fix the issue. Are you sure you're not accidentally overriding - (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath? "Select" vs. "deselect" has tripped me up in the past with Xcode's code completion.

To fix this issue This code looks like the code you'd use to pass the selected data from one view controller to another when a cell is selected, am I right?
In your code, selectedValue should be a variable declared in SecondViewController. It is where you're passing the data to.

around this issue For that when you show the small menu, add below it a invisible button (UIColor.clear) with the entire screen as a frame. And it's action is to dismiss the menu of yours.
Make sure when you dismiss the small menu to dismiss thus button as well.

may help you . Depending on how your UI is setup you can probably use EventSystems.EventSystem.IsPointerOverGameObject for checking if the pointer is over a UI element and skip the placing in this case
code :
if (placementPoseIsValid && Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
{
    if(EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId))) return;

    PlaceObject();
}

I wish this helpful for you you can do that by going to your emulator settings and activate developer mode
Open Settings on the Android device. Scroll to the very bottom of the menu and select ‘About phone’. Scroll to the very bottom of the menu and select ‘Build number’ repeatedly. After the 7th or 8th click you should see a message telling you that you are a developer. Click back to return to the main Settings menu. There should be a new ‘Developer Options’ option above to ‘About phone’ option. Select ‘Developer Options’. Under the ‘Input’ heading there is a ‘Show touches’ option. Selecting this will show all touch events on the screen including pinch to zoom gestures and so on.
