I want to make KDCircularProgressView programmatically. I included KDCircularProgressView.swift file from https://github.com/kaandedeoglu/KDCircularProgress.
Here is code form UIViewController:
private var progressView: KDCircularProgress!
private func setupProgressView(){
progressView = KDCircularProgress(frame: CGRect(x: 100, y: 100, width: 100, height: 100))
progressView.startAngle = 90
progressView.angle = 90
progressView.trackColor = UIColor.red
progressView.progressColors = [UIColor.white]
progressView.center = view.center
}
I am calling this function in viewDidLoad, but nothing is showing on screen.
add it to main view
self.view.addSubview(progressView)

I'm trying to change the width of a UIView with a slider. My problem is that instead of updating the views width my code is adding new views. I don't know how to update the view with swift playgrounds.
import UIKit
import PlaygroundSupport
class MyViewController : UIViewController {
var feelings01Slider: UISlider!
var feelingsWidth01 = 100
var dayFeelings01: UIView!
var dayFeelings02: UIView!
var dayFeelings03: UIView!
override func loadView() {
let view = UIView()
view.backgroundColor = .white
self.view = view
feelings01Slider = UISlider()
feelings01Slider.frame = CGRect(x: 62, y: 375, width: 250, height: 20)
feelings01Slider.minimumValue = 1
feelings01Slider.maximumValue = 248
feelings01Slider.value = 100
feelings01Slider.isContinuous = true
feelings01Slider.addTarget(self, action: #selector(sliderValueDidChange(sender:)), for: .valueChanged)
setUpFeelings()
view.addSubview(feelings01Slider)
}
func setUpFeelings() {
feelingsWidth01 = Int(feelings01Slider.value)
var feelingsX02 = feelingsWidth01 + 62
var feelingsWidth02 = 80
var feelingsX03 = feelingsX02 + feelingsWidth02
var feelingsWidth03 = 70
dayFeelings01 = UIView(frame: CGRect(x: 62, y: 100, width: feelingsWidth01, height: 250))
dayFeelings01.backgroundColor = .yellow
dayFeelings02 = UIView(frame: CGRect(x: feelingsX02, y: 100, width: feelingsWidth02, height: 250))
dayFeelings02.backgroundColor = .blue
dayFeelings03 = UIView(frame: CGRect(x: feelingsX03, y: 100, width: feelingsWidth03, height: 250))
dayFeelings03.backgroundColor = .red
view.addSubview(dayFeelings01)
view.addSubview(dayFeelings02)
view.addSubview(dayFeelings03)
}
#objc func sliderValueDidChange(sender:UISlider) {
feelingsWidth01 = Int(sender.value)
dayFeelings03.removeFromSuperview()
dayFeelings02.removeFromSuperview()
dayFeelings01.removeFromSuperview()
setUpFeelings()
}
}
// Present the view controller in the Live View window
PlaygroundPage.current.liveView = MyViewController()
I'm new to programming so excuse me if my code seems messy.
You don't need to replace the views with new, differently-sized views . You can just change their frames. Replace your slider selector action with this:
#objc func sliderValueDidChange(sender:UISlider) {
dayFeelings01.frame.size.width = CGFloat(sender.value)
}
Note: because the yellow view was added first, it is expanding underneath the other views. That's why you can't see it get wider. Try changing the order so it's added last and you'll see it. If you want the other views to adjust to the available space, you can update their frames too, a UIStackView might make that easy.
Good luck!
I am using some cocoa pods frame to make UICollectionView. I am able to get the right data for each cell and setup views.
I want to have different ani
The animation end point should be related to the value of dataSource.The problem is that I can't use the didSet value as I wish. The frame of subviews I added are (0,0,0,0), the values of objects keep the same as initial value outside the didSet. I am not able to access the dataSource Value in setupView function.
Expected effect is that the red bar will move from left side to the right position:
class CereCell : DatasourceCell {
override var datasourceItem: Any?{
didSet {
guard let cere = datasourceItem as? CeremonyDay else { return }
nameLabel.text = cere.name
nameLabel.frame = CGRect(x: 0, y: 0, width: 10, height: 10)
currentBar.frame = CGRect(x: 100, y: 100, width: cere.percentage*100 , height: 10)
position.x = cere.percentage
}
}
let currentBar: UIView = {
let currentBar = UIView(frame: CGRect(x: 290, y: 100, width: 300, height: 10))
currentBar.backgroundColor = .red
return currentBar
}()
override func setupViews() {
super.setupViews()
contentView.addSubview(currentBar)
let frame = currentBar.frame
print(frame)
It just print the (290, 100, 300, 10), which is not the value in didSet.
I have view controller with views: top level View Contains Container View which contains two views: bottomView, topView, as shown.
Scene
I want to display from: to: date range in the topView. In the bottomView I want to display a UIScrollView that contains two columns which I can scroll. I did that but the topView and BottomView overlap when I introduce scrollView. When I scroll I can see the views getting separated and as soon as i Let go the scrollbar they overlap again.
can someone tell me how to fix it? I just don't seem to understand how the scrollView and bottomView are to be associated.
Code below:
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
scrollView.frame = view.bounds
//scrollView.frame = innerView.bounds
innerView.frame = CGRect(x:0, y:0, width:scrollView.contentSize.width, height:scrollView.contentSize.height)
}
func buildBottomView () {
let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let ht:Int = 21
let incrX:Int = 5
let incrY:Int = 5
let gapCol1:Int = 5
let col1Width:Int = 65
let col2Width:Int = 65
let startY:Int = 5
let col1StartX:Int = 10
let col2StartX:Int = col1StartX + col1Width + gapCol1
var loadRowStartY: Int = 0
// column headers
categoryColumnLabel.text = "Interval"
categoryColumnLabel.font = UIFont.preferredFont(forTextStyle:UIFontTextStyle.subheadline)
//categoryColumnLabel.font = UIFont.systemFont(ofSize: 14)
categoryColumnLabel.frame = CGRect(x: col1StartX, y:startY, width: col1Width, height: ht)
categoryColumnLabel.textAlignment = NSTextAlignment.left
categoryColumnLabel.tag = 1
innerView.addSubview(categoryColumnLabel)
valueColumnLabel.text = "Values"
valueColumnLabel.font = UIFont.preferredFont(forTextStyle:UIFontTextStyle.subheadline)
//valueColumnLabel.font = UIFont.systemFont(ofSize: 14)
valueColumnLabel.frame = CGRect(x: col2StartX, y:startY, width: col2Width, height: ht)
valueColumnLabel.textAlignment = NSTextAlignment.center
valueColumnLabel.tag = 3
innerView.addSubview(valueColumnLabel)
let sepLine:UIView = UIView()
sepLine.frame = CGRect(x: col1StartX, y:startY+ht+incrY, width: Int(screenWidth-20), height: 2)
sepLine.backgroundColor = UIColor.darkGray
sepLine.tag = 60
loadRowStartY = startY+ht+incrX+ht
innerView.addSubview(sepLine)
for i in 0 ..< 24 {
let timeIntervalLabel = UILabel()
let value2Label = UILabel()
print("display load profile")
let loadStruct = loadDict[String(i)] as! CommercialProfile
print (loadStruct.timeInterval)
timeIntervalLabel.text = loadStruct.timeInterval
timeIntervalLabel.font = UIFont.preferredFont(forTextStyle:UIFontTextStyle.caption1)
//valueColumnLabel.font = UIFont.systemFont(ofSize: 14)
timeIntervalLabel.frame = CGRect(x: col1StartX, y:loadRowStartY, width: col1Width, height: Int(timeIntervalLabel.font.lineHeight))
timeIntervalLabel.textAlignment = NSTextAlignment.center
innerView.addSubview(timeIntervalLabel)
print(loadStruct.value)
value2Label.text = loadStruct.value
value2Label.font = UIFont.preferredFont(forTextStyle:UIFontTextStyle.caption1)
//value2Label = UIFont.systemFont(ofSize: 14)
value2Label.frame = CGRect(x: col2StartX, y:loadRowStartY, width: col2Width, height: Int(value2Label.font.lineHeight))
value2Label.textAlignment = NSTextAlignment.center
innerView.addSubview(value2Label)
loadRowStartY = loadRowStartY + incrY + Int(value2Label.font.lineHeight)
}
you are setting the bounds of the scrollView to the size of the whole view with this code: scrollView.frame = view.bounds.
The scrollView only needs to scroll the content in the bottom view. Scroll Views have their own content, that is normally larger than the viewable area of the screen/view. The scroll view just allows you to pan the viewport of that view.
So add the bottom view and setup your constraints on that. add the scrollView to the bottom view and then add your content into the scrollView.
Make sure that your bottom view has clipToBounds set to true and then you should be able to keep the headers in place and just scroll the content.
I'll try and put an example together for you shortly.
EDIT:
I've just created this simple example which shows the scroll behaviour you need. This works in a playground or just as a simple view controller. I've intentionally not used auto layout or setup constraints due to time, but you will see what you need to solve your issue
class ViewController: UIViewController {
var topView: UIView!
var bottomView: UIView!
var scrollView: UIScrollView!
var contentView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
let screenSize = UIScreen.main.bounds
self.topView = UIView(frame: CGRect(x: 0, y: 0, width: screenSize.width, height: 100))
self.bottomView = UIView(frame: CGRect(x: 0, y: 100, width: screenSize.width, height: screenSize.height - 100))
self.scrollView = UIScrollView(frame: CGRect(x: 0, y: 100, width: screenSize.width, height: screenSize.height - 100))
self.contentView = UIView(frame: CGRect(x: 0, y: 0, width: screenSize.width, height: screenSize.height * 3))
self.view.backgroundColor = .white
self.view.addSubview(self.topView)
self.view.addSubview(self.bottomView)
self.bottomView.addSubview(self.scrollView)
self.scrollView.addSubview(self.contentView)
self.bottomView.clipsToBounds = true
self.scrollView.contentSize = CGSize(width: screenSize.width, height: screenSize.height * 3)
self.contentView.backgroundColor = .gray
}
}
I have one view (DataInputContainerView) and i load that view to DataController. This is my code for load DataInputContainerView to DataController
var heightInput: CGFloat = 50
lazy var inputContainerView: DataInputContainerView = {
let dataInputContainerView = DataInputContainerView(frame: CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.heightInput))
dataInputContainerView.dataController = self
return dataInputContainerView
}()
That code was work. But i want to load again, for example
#IBAction func loadAgain(sender: AnyObject) {
self.heightInput += 15
// Put here to load that view again
}
I want make height view +15 and load again
So you want code that will create multiple instances of your DataInputContainerView class?
Don't use a lazy property. That creates a single instance the first time it's called, and the returns the same instance each time thereafter.
Instead, create a function that returns a DataInputContainerView:
func makeDataInputContainerView(height: height: CGFloat) ->
DataInputContainerView {
let rect = CGRect(x: 0, y: 0, width: self.view.frame.width,
height: height)
let dataInputContainerView = DataInputContainerView(frame: rect)
dataInputContainerView.dataController = self
return dataInputContainerView
}
And then call it:
var height = 50
for (_ in 1...5) {
var newDataInputContainerView = makeDataInputContainerView(height: height)
self.view.addSubview(newDataInputContainerView)
}
In my app I'm using a custom UIActivityIndicator view (this) and it works great.
I have an UITableView and I want the indicator over the tableview on loading data. To solve the problem I have created an empty view with a background above all and when I need to start indicator's animation I simply hide tableview and show the empty view + the indicator.
The result is this:
I saw somewhere that I can use instead something like this:
How can I do?
Thanks in advance.
You could try adding a translucent Black view over the Table View and put the custom activity indicator code as a subview in the Black view.
let aBlackView = UIView(frame: CGRectMake(0, 0, self.view.bounds.width, self.view.bounds.height))
aBlackView.backgroundColor = UIColor.blackColor()
aBlackView.alpha = 0.75 // Change the alpha depending on how much transparency you require
let aMainWindow = UIApplication.sharedApplication().delegate!.window
aMainWindow!!.addSubview(aBlackView)
/* Enter you code for NVActivityIndicatorViewable here */
aBlackView.addSubview(/* NVActivityIndicatorViewable */)
Once you are done with your request, you can remove the Black view by calling this code:
aBlackView.removeFromSuperview()
I created a activity showing screen . I used in every where in my project.
//ProgressBarNotification.swift
import Foundation
import UIKit
class ProgressBarNotification {
internal static var strLabel = UILabel()
internal static var messageFrame = UIView()
internal static var activityIndicator = UIActivityIndicatorView()
internal static func progressBarDisplayer(msg:String,indicator:Bool ){
let view1 = UIApplication.sharedApplication().delegate?.window!!.rootViewController?.view
view1?.userInteractionEnabled = false
strLabel = UILabel(frame: CGRect(x: 50, y: 0, width: 200, height: 50))
strLabel.text = msg
strLabel.textColor = UIColor.whiteColor()
messageFrame = UIView(frame: CGRect(x: view1!.frame.midX - 90, y: view1!.frame.midY - 25 , width: 180, height: 50))
messageFrame.layer.cornerRadius = 15
messageFrame.backgroundColor = UIColor(white: 0, alpha: 0.7)
if indicator {
activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.White)
activityIndicator.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
activityIndicator.startAnimating()
messageFrame.addSubview(activityIndicator)
}
messageFrame.addSubview(strLabel)
view1!.addSubview(messageFrame)
}
internal static func removeProgressBar() {
let view1 = UIApplication.sharedApplication().delegate?.window!!.rootViewController?.view
_ = view1?.subviews.filter({ (view) -> Bool in
if view == ProgressBarNotification.messageFrame {
view.removeFromSuperview()
}
return false
})
ProgressBarNotification.messageFrame.removeFromSuperview()
view1?.userInteractionEnabled = true
}
deinit{
}
}
Usage
//To start Loader
ProgressBarNotification.progressBarDisplayer("Loading", indicator: true)
//Stop
ProgressBarNotification.removeProgressBar()
