How can I fit a subView to the Proper Dimensions of the view I have Created in the story board?
For example
self.popUpView.addSubview(chart)
is presenting my display that i would like to span over the view I have in the story board.
class PopVC: UIViewController {
#IBOutlet weak var popUpView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
let chart = Chart(frame: self.popUpView.frame)
let data = [(x: 0.0, y: 0), (x: 3, y: 2.5), (x: 4, y: 2), (x: 5, y: 2.3), (x: 7, y: 3), (x: 8, y: 2.2), (x: 9, y: 2.5)]
let series = ChartSeries(data: data)
series.area = true
chart.xLabels = [0, 3, 6, 9, 12, 15, 18, 21, 24]
chart.xLabelsFormatter = { String(Int(round($1))) + "h" }
chart.add(series)
//Circle Edge on barChartView
popUpView.layer.cornerRadius = 10
popUpView.layer.masksToBounds = true
self.popUpView.addSubview(chart)
}
#IBAction func closePopUp(_ sender: Any) {
dismiss(animated: true, completion: nil)
}
}//END CLASS
You haven't really posted what isn't working about your solution, but the immediate thing I notice is that you're setting the frame of your Chart to popUpView.frame, when you should set it to popUpView.bounds. This will ensure the origin of Chart is the origin of popUpView within popUpView's coordinate system.
So, to show the example, change your initialization code to this:
let chart = Chart(frame: self.popUpView.bounds)
If you want to create a rect that makes the chart the same size as popUpView, but 20pt from the bottom (for example) you could say:
let chart = Chart(frame: CGRect(x: 0, y: 0, width: self.popUpView.bounds.size.width, height: self.popUpView.bounds.size.height - 20))
Maybe you want it to be half the height of popUpView:
let chart = Chart(frame: CGRect(x: 0, y: 0, width: self.popUpView.bounds.size.width, height: self.popUpView.bounds.size.height / 2))
Etc.

I have an icon that I programmatically display.
How can I display a solid, colored disk behind the icon, at the same screen position?
Icon is opaque.
I will sometimes programmatically change screen position and disk's diameter and color.
Here's how I programmatically display the icon now.............
DispatchQueue.main.async
{
ViewController.wrist_band_UIImageView.frame = CGRect( x: screen_position_x,
y: screen_position_y,
width: App_class.screen_width,
height: App_class.screen_height)
}
UPDATE #1 for D.Mika below...
UPDATE #2 for D.Mika below...
import UIKit
import Foundation
class ViewController: UIViewController
{
static var circleView: UIView!
static let wrist_band_UIImageView: UIImageView = {
let theImageView = UIImageView()
theImageView.image = UIImage( systemName: "applewatch" )
theImageView.translatesAutoresizingMaskIntoConstraints = false
return theImageView
}()
override func viewDidLoad()
{
super.viewDidLoad()
view.addSubview( ViewController.wrist_band_UIImageView )
// Init disk image:
ViewController.circleView = UIView(frame: CGRect(x: 0.0, y: 0.0, width: 100.0, height: 100.0))
ViewController.circleView.backgroundColor = .red
ViewController.circleView.layer.cornerRadius = view.bounds.size.height / 2.0
ViewController.circleView.clipsToBounds = true
// Add view to view hierarchy below image view
ViewController.circleView.insertSubview(view, belowSubview: ViewController.wrist_band_UIImageView)
App_class.display_single_wearable()
}
}
class App_class

ViewController.wrist_band_UIImageView.frame = CGRect(x: 0, y: 0,
width: 100, height: 100)
ViewController.circleView.frame = CGRect( x: 0,
y: 0,

You can display a colored circle using the following view:
circleView = UIView(frame: CGRect(x: 0.0, y: 0.0, width: 100.0, height: 100.0))
circleView.backgroundColor = .red
circleView.layer.cornerRadius = view.bounds.size.height / 2.0
circleView.clipsToBounds = true
// Add view to view hierarchy below image view
view.insertSubview(circleView, belowSubview: wrist_band_UIImageView)
You can change it's position and size by applying a new frame. But you have to change the layer's cornerRadius accordingly.
This is a simple example in a playground:
Edit:
I've modified the sample code to add the view the view hierarchy.
BUT, you still need to adjust the circle's frame, when you modify the image view's frame. (and the cornerRadius accordingly). For example
DispatchQueue.main.async
{
ViewController.wrist_band_UIImageView.frame = CGRect( x: screen_position_x,
y: screen_position_y,
width: App_class.screen_width,
height: App_class.screen_height)
circleView.frame = CGRect( x: screen_position_x,
y: screen_position_y,
width: App_class.screen_width,
height: App_class.screen_height)
circleView.layer.cornerRadius = App_class.screen_width
}
And you need to add a variable to the viewController holding the reference to the circle view, like:
var circleView: UIView!
The following answer works.
The answers from d.mika above did not work. Plus, he was insulting. ;-)
// Show red circle
let circlePath = UIBezierPath(arcCenter: CGPoint(x: 200, y: 400), radius: CGFloat(40), startAngle: CGFloat(0), endAngle: CGFloat(Double.pi * 2), clockwise: true)
let shapeLayer = CAShapeLayer()
shapeLayer.path = circlePath.cgPath
// Change the fill color
shapeLayer.fillColor = UIColor.red.cgColor
// You can change the stroke color
shapeLayer.strokeColor = UIColor.red.cgColor
// You can change the line width
shapeLayer.lineWidth = 3.0
view.layer.addSublayer(shapeLayer)
Im made and DropDown Menu to select Action like the GIF below.
Therefore I made a Subview and animated it in.
When animating the Subview out, it looks really weird.
In particular the problem is that it just looks like a blank small bar and not like the Menu.
Does anyone know where the problem might be?
The ViewController I'm making the Subview of is a simple ViewController with a TableView inside and 1 prototype cell.
Code:
let blackView = UIView()
var tvx: OptionsVC = OptionsVC()
var h: CGFloat!
.
func optionsClicked() {
self.h = CGFloat(70 + (52 * (OptionsVC().arrayFunctionCellNames.count)))
navigationController?.hidesBarsOnTap = false
tvx = self.storyboard?.instantiateViewController(withIdentifier: "options") as! OptionsVC
if let window = UIApplication.shared.keyWindow {
blackView.backgroundColor = UIColor(white: 0, alpha: 0.5)
blackView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleDismiss)))
view.addSubview(blackView)
view.addSubview(tvx.view)
let y = (self.navigationController?.navigationBar.frame.size.height)! + UIApplication.shared.statusBarFrame.height
tvx.view.frame = CGRect(x: 0, y: (y - self.h), width: view.frame.width, height: h)
blackView.frame = CGRect(x: 0, y: y, width: view.frame.width, height: view.frame.height)
blackView.alpha = 0
UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: {
self.blackView.alpha = 1
self.tvx.view.frame = CGRect(x: 0, y: y, width: self.view.frame.width, height: self.h)
self.blackView.frame = CGRect(x: 0, y: (y + self.h), width: self.view.frame.width, height: self.view.frame.height)
}, completion: nil)
}
}
.
func handleDismiss() {
UIView.animate(withDuration: 5.5, animations: {
let y = (self.navigationController?.navigationBar.frame.size.height)! + UIApplication.shared.statusBarFrame.height
self.blackView.alpha = 0
if let window = UIApplication.shared.keyWindow {
self.blackView.frame = CGRect(x: 0, y: y, width: self.view.frame.width, height: self.view.frame.height)
self.tvx.view.frame = CGRect(x: 0, y: (y - self.h), width: self.view.frame.width, height: self.h)
}
}, completion: {(finished:Bool) in
self.blackView.removeFromSuperview()
self.tvx.view.removeFromSuperview()
self.navigationController?.hidesBarsOnTap = true
})
}
GIF of BUG:
I made it so slow so you can better see it
Edit: My Solution
The problem was the constraints I set on my subview controller. Normally you set them to all sides, in my case, with was really weird I had to set them only to the bottom and sides. If I set some to the top, it would always do this bug.
You haven't really provided enough information for us to understand what's going on. What are tvx, blackView and self? What is the self.h variable? (From the animation it looks like you're changing the height of your "menu" view to be much shorter before you begin the animation code.)
Do you have a view controller contained inside another one using an embed segue?
If so, you should probably animate the constraints on the container view, not the child view controller's view.
As Glenn and D. Greg say in their comments, you should really be adding constraints to your views, hooking up outlets to those constraints, and animating changes to the constraint's constants rather than manipulating your view's frames directly. Animating changes to your view's frames isn't reliable when you're using AutoLayout, since AutoLayout can change your view's size and position out from under your animation code. That code looks like this, (in broad terms, no specific to your code)
myViewAConstraint.constant = someNewValue
myViewBConstraint.constant = someOtherValue
UIView.animate(withDuration: 5.5,
animations: {
someView.alpha = 0 //If you want the view to fade as it animates
self.view.layoutIfNeeded()
},
completion: { (finished:Bool) in
}
)
Currently there is a view I'm trying to translate(move), rotate and scale a view at the same time. For so strange reason it's only scaling it when I put scale at the bottom. But when I change the order and put the scaling first it rotates and translates the view properly but the scale of the view changes briefly to its correct scale before changing back to its original size. I need it to stay in it's scaled form. Here is the code:
class ViewController: UIViewController {
let newView = UIView(frame: CGRect(x: 10, y: 10, width: 100, height: 100))
override func viewDidLoad() {
super.viewDidLoad()
self.view.addSubview(newView)
UIView.animate(withDuration: 1.0, animations: {
self.newView.transform = CGAffineTransform(translationX: 50, y: 70)//translation
self.newView.transform = CGAffineTransform(rotationAngle: -CGFloat.pi / 2)//rotation
self.newView.transform = CGAffineTransform(scaleX: 1, y: 0.5)//scale
})
}
}
Try combine the transforms first, then apply them at a time:
let translate = CGAffineTransform(translationX: 50, y: 70)
UIView.animate(withDuration: 1.0, animations: {
self.view.transform = translate.rotated(by: -CGFloat.pi / 2).scaledBy(x: 1, y: 0.5)
})
I want to have an UIView to appear by scaling from left to right if I hit a button. If I hit the button again, the view should scale away from right to left.
I found an explanation how to do it for left to right, but even this solution is working only once. If I hide the view and play the animation again it scales it from the centre again.
Also scaling it back from right to left doesn't work either as it disappears immdiatly without any animation.
Here's my code so far:
if(!addQuestionaryView.isHidden)
{
//Reset input if view is hidden
addQuestionaryInput.text = ""
self.addQuestionaryView.isHidden = false
let frame = addQuestionaryView.frame;
let rect = CGRect(x: frame.origin.x, y: frame.origin.y, width: frame.width, height: frame.height)
let leftCenter = CGPoint(x: rect.minX, y: rect.minY)
addQuestionaryView.layer.anchorPoint = CGPoint(x:1,y: 0.5)
addQuestionaryView.layer.position = leftCenter
UIView.animate(withDuration: 0.6,
animations: {
self.addQuestionaryView.transform = CGAffineTransform(scaleX: 0, y: 1)
},
completion: { _ in
self.addQuestionaryView.isHidden = true
})
}
else
{
self.addQuestionaryView.isHidden = false
let frame = addQuestionaryView.frame;
let rect = CGRect(x: frame.origin.x, y: frame.origin.y, width: frame.width, height: frame.height)
let leftCenter = CGPoint(x: rect.minX, y: rect.midY)
addQuestionaryView.layer.anchorPoint = CGPoint(x:0,y: 0.5);
addQuestionaryView.layer.position = leftCenter
addQuestionaryView.transform = CGAffineTransform(scaleX: 0, y: 1)
UIView.animate(withDuration: 0.6,
animations: {
self.addQuestionaryView.transform = CGAffineTransform(scaleX: 1, y: 1)
},
completion: nil)
}
As said the appearing part works once and then starts from the centre again. The disappearing part doesn't work at all.
I don't know what "to scale it so it has a little look like Android reveal animations" means (and I hope I never do; I've never seen an Android phone, I never hope to see one).
But do you mean something like this? This is done by animating a mask in front of the view, thus revealing and then hiding it:
Here's the code used in that example:
class MyMask : UIView {
override func draw(_ rect: CGRect) {
let r = CGRect(x: 0, y: 0, width: rect.width/2.0, height: rect.height)
UIColor.black.setFill()
UIGraphicsGetCurrentContext()?.fill(r)
}
}
class ViewController: UIViewController {
#IBOutlet weak var lab: UILabel!
var labMaskOrigin = CGPoint.zero
var didAddMask = false
override func viewDidLayoutSubviews() {
if didAddMask {return}
didAddMask = true
let mask = MyMask()
mask.isOpaque = false
let w = self.lab.bounds.width
let h = self.lab.bounds.height
mask.frame = CGRect(x: -w, y: 0, width: w*2, height: h)
self.lab.mask = mask
self.labMaskOrigin = mask.frame.origin
}
var labVisible = false
func toggleLabVisibility() {
labVisible = !labVisible
UIView.animate(withDuration: 5) {
self.lab.mask!.frame.origin = self.labVisible ?
.zero : self.labMaskOrigin
}
}
}
Remove this:
addQuestionaryView.layer.anchorPoint = CGPoint(x:0,y: 0.5);
addQuestionaryView.layer.position = leftCenter
addQuestionaryView.transform = CGAffineTransform(scaleX: 0, y: 1)
Then in your animate with duration block use the code below instead of CGAfflineTransform
addQuestionaryView.frame = CGRect(0,0,500,100)
Replace 500 width whatever width you want it to be.
Ans to close it back up do this:
addQuestionaryView.frame = CGRect(0,0,0,100);
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);
