I have this code. My goal is to make an animation of red screen blinking. Everything goes well until textLabel. It doesn't want to change its color at all. Can anyone help me how to fix it ? (Background color is changing, so the code should be correct in overall).
I am trying to create a collection view similar to Apple's shortcuts app. I was able to create the cells themselves but I am having a hard time create an individual data cell (if that makes sense). My goal is to have each cell display a title, subtitle, and possible a play button.
Right now, I am having a hard time figuring out where I am going wrong with my constraints or possible my data structure (its crashing on the background and the text isn't showing on the colored cell).
struct customData {
var title: String
var subtitle: String
}
class ViewController: UICollectionViewController, UICollectionViewDelegateFlowLayout {
//Mark : All Cards
fileprivate let data = [
customData (title: "iOS", subtitle: "12 Tips"),
customData (title: "iPadOS", subtitle: "11 Tips"),
customData (title: "macOS", subtitle: "10 Tips"),
customData (title: "tvOS", subtitle: "19 Tips"),
customData (title: "watchOS", subtitle: "18 Tips"),
customData (title: "Accessories", subtitle: "17 Tips"),

This is what I see:
To fix the warnings that say constraint cannot be satisfied you should set translatesAutoresizingMaskIntoConstraints of listName to false.
override init(frame: CGRect) {
super.init(frame: frame)
setupCell()
contentView.addSubview(listName)
listName.translatesAutoresizingMaskIntoConstraints = false // Add this
listName.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 10).isActive = true
listName.leftAnchor.constraint(equalTo: contentView.leftAnchor, constant: 30).isActive = true
listName.widthAnchor.constraint(equalTo: contentView.widthAnchor, constant: 12).isActive = true
listName.heightAnchor.constraint(equalTo: contentView.heightAnchor, constant: 80).isActive = true
}
Rounded corner is working great on iOS 12 and below, but it's broken on iOS 13. I've created a custom Segment control class.
Code:
class SegmentedControl: UISegmentedControl {
override func layoutSubviews() {
super.layoutSubviews()
layer.cornerRadius = self.bounds.size.height / 2.0
layer.borderColor = UIColor(red: 170.0/255.0, green: 170.0/255.0, blue: 170.0/255.0, alpha: 1.0).cgColor
layer.borderWidth = 1.0
layer.masksToBounds = true
clipsToBounds = true
}
}
I've gone through this post - How to change the colors of a segment in a UISegmentedControl in iOS 13?
but I couldn't get any solution.
Screenshot:
I was facing the same issue on iOS 13. Then I dug into its view hierarchy then I found it has multiple subviews. So I made a trick for iOS 13. You have to do following changes for iOS 13 -
ChangeselectedSegmentTintColor to Clear - self.selectedSegmentTintColor = .clear
Add following code snippet inside layoutSubviews -
for i in 0...subviews.count - 1{
if let subview = subviews[i] as? UIImageView{
if i == self.selectedSegmentIndex {
subview.backgroundColor = UIColor(red: 170.0/255.0, green: 170.0/255.0, blue: 170.0/255.0, alpha: 1.0)
}else{
subview.backgroundColor = .clear
}
}
}
I hope it will help you.
Similar to other solution I have Following Sub-Class Segment control
UISegmentedControl
Which gives following result -
class OYSegmentControl: UISegmentedControl {
override func layoutSubviews(){
super.layoutSubviews()
let segmentStringSelected: [NSAttributedString.Key : Any] = [
NSAttributedString.Key.font : UIFont.fontActionLabel(ofSize: 14.0),
NSAttributedString.Key.foregroundColor : UIColor.white
]
let segmentStringHighlited: [NSAttributedString.Key : Any] = [
NSAttributedString.Key.font : UIFont.fontActionLabel(ofSize: 14.0),
NSAttributedString.Key.foregroundColor : #colorLiteral(red: 0.5567105412, green: 0.5807551742, blue: 0.6022000909, alpha: 1)
]
setTitleTextAttributes(segmentStringHighlited, for: .normal)
setTitleTextAttributes(segmentStringSelected, for: .selected)
setTitleTextAttributes(segmentStringHighlited, for: .highlighted)
layer.masksToBounds = true
if #available(iOS 13.0, *) {
selectedSegmentTintColor = #colorLiteral(red: 0, green: 0.861200273, blue: 0.67304039, alpha: 1)
} else {
tintColor = #colorLiteral(red: 0, green: 0.861200273, blue: 0.67304039, alpha: 1)
}
backgroundColor = #colorLiteral(red: 0.9191747308, green: 0.9334954619, blue: 0.9506797194, alpha: 1)
//corner radius
let cornerRadius = bounds.height / 2
let maskedCorners: CACornerMask = [.layerMinXMinYCorner, .layerMinXMaxYCorner, .layerMaxXMinYCorner, .layerMaxXMaxYCorner]
//background
clipsToBounds = true
layer.cornerRadius = cornerRadius
layer.maskedCorners = maskedCorners
let foregroundIndex = numberOfSegments
if subviews.indices.contains(foregroundIndex),
let foregroundImageView = subviews[foregroundIndex] as? UIImageView {
foregroundImageView.image = UIImage()
foregroundImageView.clipsToBounds = true
foregroundImageView.layer.masksToBounds = true
foregroundImageView.backgroundColor = #colorLiteral(red: 0, green: 0.861200273, blue: 0.67304039, alpha: 1)
foregroundImageView.layer.cornerRadius = bounds.height / 2 + 5
foregroundImageView.layer.maskedCorners = maskedCorners
}
}
override func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
return false
}
}
Language: Swift 5.1
NOTE: This only works if you have outlet / frame set from Storyboard.
Frame from code will cause issues.
The extra 5 px on cornerRadius,a hack to make it better round rect.
I ended up using - https://github.com/alokc83/MASegmentedControl as my use-case was from Code only view.
Swift 5
If you use a subclass:
override func layoutSubviews() {
super.layoutSubviews()
roundCorners(radius: frame.height / 2)
if #available(iOS 13.0, *) {
selectedSegmentTintColor = .clear
} else {
tintColor = .clear
}
for (index, subview) in subviews.enumerated() {
if ((subviews[index] as? UIImageView) != nil) && index == selectedSegmentIndex {
subview.backgroundColor = .white
subview.roundCorners(radius: subview.frame.height / 2)
} else {
subview.backgroundColor = .clear
}
}
}
Conienience method:
extension UIView {
func roundCorners(radius: CGFloat) {
layer.roundCorners(radius: radius)
self.clipsToBounds = true
}
}
If you use the default segmented control, you just prefix with name of your segmented control:
mySegmentedControl.selectedSegmentTintColor = .clear
for (index, subview) in mySegmentedControl.subviews.enumerated() {
.....
}
Make a custom class for segment
class CustomSegmentedControl: UISegmentedControl {
override func layoutSubviews() {
super.layoutSubviews()
layer.cornerRadius = self.bounds.size.height / 2.0
layer.borderColor = use_your_custom_color
layer.borderWidth = 1.0
layer.masksToBounds = true
clipsToBounds = true
for i in 0...subviews.count - 1{
if let subview = subviews[i] as? UIImageView{
if i == self.selectedSegmentIndex {
subview.backgroundColor = use_your_custom_color
}else{
subview.backgroundColor = .white
}
}
}
}}
May be this will easy to use like this
#IBOutlet weak var reminderSegmentControl: CustomSegmentedControl!
this code works for me iOS 13 - Swift 5.1
segment.layer.cornerRadius = 12
segment.layer.borderWidth = 1
segment.layer.borderColor = UIColor.black.cgColor
segment.font(name: "TheSans-Plain", size: 14)
segment.clipsToBounds = true
segment.layer.masksToBounds = true
if #available(iOS 13.0, *) {
segment.selectedSegmentTintColor = .red
}
I am developing an application for an online forum with DTCoreText to display thread replies that parsed from BBCode to HTML with text and images inside custom cells in a UITableView.

Try this category - it works for me
extension UIImageView {
public func imageFromUrl(url: URL?) {
if let url = url {
let task = URLSession.shared.dataTask(with: url) { data, response, error in
guard let data = data, error == nil else { return }
DispatchQueue.main.async { [weak self] in
self?.image = UIImage(data: data)
}
}
task.resume()
}
}
}
I want to go to another view controller when pressing button my btnSignUp, If I write code like this I have error "sigabrt". What I should do?
import UIKit
import SnapKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = UIColor(red: 15/255, green: 52/255, blue: 100/255, alpha: 1)
createTop()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func createTop() {
let topView = UIView()
self.view.addSubview(topView)
topView.backgroundColor = UIColor(red: 15/255, green: 52/255, blue: 100/255, alpha: 1)
topView.snp_makeConstraints { (make) -> Void in
make.width.equalTo((self.view.frame.width/10)*8)
make.height.equalTo(self.view.frame.height/5)
make.centerX.equalTo(self.view)
make.top.equalTo(self.view).offset(self.view.frame.height/15)
}
let btnSignUp = UIButton()
self.view.addSubview(btnSignUp)
btnSignUp.backgroundColor = UIColor(red: 15/255, green: 52/255, blue: 100/255, alpha: 1)
btnSignUp.layer.borderColor = UIColor.whiteColor().CGColor
btnSignUp.layer.borderWidth = 1
btnSignUp.layer.cornerRadius = 6
btnSignUp.setTitle("Sign Up", forState: UIControlState.Normal)
btnSignUp.titleLabel?.font = UIFont(name: "AvenirNext-Regular", size: 17)
btnSignUp.snp_makeConstraints { (make) -> Void in
make.width.equalTo(((self.view.frame.width/10)*7)+40)
make.height.equalTo(self.view.frame.height/13)
make.top.equalTo(ORView.snp_bottom).offset(20)
make.centerX.equalTo(self.view)
}
btnSignUp.addTarget(self, action: "buttonAction", forControlEvents: UIControlEvents.TouchUpInside)
func buttonAction(sender:UIButton!)
{
let signUpVC = SignUpViewController()
self.presentViewController(signUpVC, animated: true, completion: nil)
}
}
}
Your action selector buttonAction doesn't match your function declaration - It takes an argument, so the selector will be buttonAction:
btnSignUp.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
Additionally, check your parentheses. It appears that your buttonAction function is declared inside func createTop()
func createTop() {
let topView = UIView()
self.view.addSubview(topView)
topView.backgroundColor = UIColor(red: 15/255, green: 52/255, blue: 100/255, alpha: 1)
topView.snp_makeConstraints { (make) -> Void in
make.width.equalTo((self.view.frame.width/10)*8)
make.height.equalTo(self.view.frame.height/5)
make.centerX.equalTo(self.view)
make.top.equalTo(self.view).offset(self.view.frame.height/15)
}
let btnSignUp = UIButton()
self.view.addSubview(btnSignUp)
btnSignUp.backgroundColor = UIColor(red: 15/255, green: 52/255, blue: 100/255, alpha: 1)
btnSignUp.layer.borderColor = UIColor.whiteColor().CGColor
btnSignUp.layer.borderWidth = 1
btnSignUp.layer.cornerRadius = 6
btnSignUp.setTitle("Sign Up", forState: UIControlState.Normal)
btnSignUp.titleLabel?.font = UIFont(name: "AvenirNext-Regular", size: 17)
btnSignUp.snp_makeConstraints { (make) -> Void in
make.width.equalTo(((self.view.frame.width/10)*7)+40)
make.height.equalTo(self.view.frame.height/13)
make.top.equalTo(ORView.snp_bottom).offset(20)
make.centerX.equalTo(self.view)
}
btnSignUp.addTarget(self, action: "buttonAction", forControlEvents: UIControlEvents.TouchUpInside)
}
func buttonAction(sender:UIButton!) {
let signUpVC = SignUpViewController()
self.presentViewController(signUpVC, animated: true, completion: nil)
}
Finally, I doubt that you want to get your new view controller by SignUpViewController() - if you are using a storyboard you want to call instantiateViewControllerWithIdentifier
