When using a UIView as an SCNMaterialProperty in a SceneKit scene, can that view be part of the responder chain?
To clarify how:
omg_you_can_use_an_actual_uiview_now = UIView(frame: CGRect(x: 0, y: 0, width: 500, height: 500))
material_plane.diffuse.contents = omg_you_can_use_an_actual_uiview_now
let geom_plane = SCNPlane(width: 1, height: 1)
geom_plane.materials = [material_plane]

I want bView to be free of shadows. How can I achieve this?
I want to shadow all subviews of the superView, so I cannot remove the shadow settings of the superView.
let superView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height))
superView.layer.shadowColor = UIColor.lightGray.cgColor
superView.layer.shadowOffset = CGSize(width: 0, height: 3)
superView.layer.shadowOpacity = 0.2
superView.layer.shadowRadius = 5
self.view.addSubview(superView)
let aView: UIView = UIView(frame: CGRect(x: 10, y: 100, width: 100, height: 100))
aView.backgroundColor = .white
superView.addSubview(aView)
let bView: UIView = UIView(frame: CGRect(x: 10, y: 230, width: 100, height: 100))
bView.backgroundColor = .white
superView.addSubview(bView)
I have tried bView.clipsToBounds = true but it's not working.
If you give superView a non-clear background color then none of its subviews will get a shadow. You can then apply a shadow to the subviews that you want to have a shadow.
let superView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 350))
superView.backgroundColor = .white // <-- Add this line
superView.layer.shadowColor = UIColor.black.cgColor
superView.layer.shadowOffset = CGSize(width: 0, height: 3)
superView.layer.shadowOpacity = 0.2
superView.layer.shadowRadius = 5
view.addSubview(superView)
let aView: UIView = UIView(frame: CGRect(x: 10, y: 100, width: 100, height: 100))
aView.backgroundColor = .white
// Add shadow to aView
aView.layer.shadowColor = UIColor.black.cgColor
aView.layer.shadowOffset = CGSize(width: 0, height: 3)
aView.layer.shadowOpacity = 0.2
aView.layer.shadowRadius = 5
superView.addSubview(aView)
let bView: UIView = UIView(frame: CGRect(x: 10, y: 230, width: 100, height: 100))
bView.backgroundColor = .white
superView.addSubview(bView)
If you have several views that need a shadow then I would define a method to make it easier:
extension UIView {
func addShadow() {
layer.shadowColor = UIColor.black.cgColor
layer.shadowOffset = CGSize(width: 0, height: 3)
layer.shadowOpacity = 0.2
layer.shadowRadius = 5
}
}
Then your code becomes something like this:
let superView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 350))
superView.backgroundColor = .white
superView.addShadow()
view.addSubview(superView)
let aView: UIView = UIView(frame: CGRect(x: 10, y: 100, width: 100, height: 100))
aView.backgroundColor = .white
aView.addShadow()
superView.addSubview(aView)
let bView: UIView = UIView(frame: CGRect(x: 10, y: 230, width: 100, height: 100))
bView.backgroundColor = .white
superView.addSubview(bView)
I am making a photo app that I want the imagePicker screen to have blocks of red to pre mask the photo before it crops. My following code gets a roadblock on the top x axis. I would like to place another red box along the entire y axis where the yellow rectangle is.
let blockView = UIView.init(frame: CGRect.init(x: 0, y: 0, width: self.view.frame.size.width, height: 150))
blockView.backgroundColor = UIColor.red
imagePicker.cameraOverlayView = blockView
Please try the following :
let mainView = UIView.init(frame: CGRect.init(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height-150))
let blockView = UIView.init(frame: CGRect.init(x: 0, y: 0, width: self.view.frame.size.width, height: 150))
blockView.backgroundColor = UIColor.red
let blockView1 = UIView.init(frame: CGRect.init(x: 0, y: 170, width: 100, height: self.view.frame.size.height-320))
blockView1.backgroundColor = UIColor.green
mainView.addSubview(blockView)
mainView.addSubview(blockView1)
imagePicker.cameraOverlayView = mainView
I have a skscene in which i show subview and i want a "Game Over" label in it.
var gameoversub = UIView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
func addsubview() {
gameoversub.backgroundColor = UIColor.black
self.view?.addSubview(gameoversub)
gameoversub.center = (super.scene?.anchorPoint)!
gameoversub.bounds = CGRect(x: 0, y: 0, width: (super.scene?.frame.size.width)!, height:(super.scene?.frame.size.height)!)
gameoversub.addSubview(titleLabel)
}
It says, I can't add SKLabelNode, it wants UIView. Some solutions?
For the life of me, I can't figure out how to center a UIButton in UIScrollView...
let sv = UIScrollView(frame: CGRect(x: 0, y: 0, width: 300, height: 600))
let b = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
sv.addSubview(b)
b.center = sv.center
No matter what I do, the button seems to be off center. This logic works in normal UIView. Why doesn't it with UIScrollView?
you can also use
let b = UIButton(frame: CGRect(x: sv.frame.size.width/2 -15, y: sv.frame.size.height/2 -15, width: 30, height: 30))
for your code first check value of sv.center, if it is OK and your UI is not updating then call layoutIfneeded

I am trying to make a view transform and kind of have a circle effect until it reaches certain points then it just fills a rectangle. This is for a material design project I am working on. All the code is in Swift 2.0 on an iOS 8 or above device.
func helloWorld(sender: UIButton) {
let point = sender.frame.origin
let rippleViewInitFrame: CGRect = CGRect(x: point.x, y: point.y, width: 4, height: 4)
let rippleView: UIView = UIView(frame: rippleViewInitFrame)
rippleView.backgroundColor = UIColor.MDColor.blue
let bounds: CGRect = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height)
rippleView.layer.masksToBounds = true
rippleView.layer.cornerRadius = 2
self.view.addSubview(rippleView)
UIView.animateWithDuration(0.5, delay: 0.0, options: .CurveEaseInOut, animations: {
rippleView.transform = CGAffineTransformMakeScale(200.0, 200.0)
rippleView.bounds = bounds
}, completion: {
finished in
print(rippleView.frame.origin.x)
})
}
Currently the view just grows beyond the size of the screen.
The print statement returns -37176 instead of say 0. I want it to fill the screen and nothing more.
If you want it to fill a rectangle.
1) create a rectangular container UIView.
2) add your rippleView as a subview to this rectangular uiview.
set the clipsToBounds property to yes of your container view.
and just do the animation.
let rectView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100));
rectView.backgroundColor = UIColor.redColor()
// initialRippleView
let rippleView = UIView(frame: CGRect(x: 15, y: 15, width: 2, height: 2));
rippleView.backgroundColor = UIColor.whiteColor()
rippleView.cornerRadius = rippleView.width / 2;
rectView.addSubview(rippleView);
rectView.clipsToBounds = true;
UIView.animateWithDuration(5) { () -> Void in
rippleView.transform = CGAffineTransformMakeScale(100, 100);
}
Try in playground.
import UIKit
import XCPlayground
// the main View
let iPhone = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 568));
iPhone.backgroundColor = UIColor.greenColor();
// the rect View that will be the bounds of the animation
let rectView = UIView(frame: CGRect(x: 0, y: 0, width: 150, height: 150));
rectView.backgroundColor = UIColor.redColor()
rectView.center = iPhone.center;
// initialRippleView
let rippleView = UIView(frame: CGRect(x: 15, y: 15, width: 2, height: 2));
rippleView.layer.cornerRadius = 1;
rippleView.backgroundColor = UIColor.whiteColor()
iPhone.addSubview(rectView);
rectView.addSubview(rippleView);
// this property clips the drawings of subview to be clipped to the bounds of rectView.
rectView.clipsToBounds = true;
UIView.animateWithDuration(5) { () -> Void in
// you may need to calculate the right scale factor
rippleView.transform = CGAffineTransformMakeScale(200, 200);
}
// Playground stuff
XCPShowView("Container View", view: iPhone);
