Today extension showing shifted from left and bottom in swift 4 - today-extension

I have created a today extension. I have set a image in the background but it is showing margin in left and bottom.
I think extension area showing shifted from left and bottom and I am not able understand why this happens. I have tested it in iPod (iOS: 9.3.5)
My TodayViewController code is: -
class TodayViewController: UIViewController, NCWidgetProviding {
#IBOutlet weak var lblTitle: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
lblTitle.text = "My Widget"
if #available(iOSApplicationExtension 10.0, *) { }
else
{
preferredContentSize = CGSize(width: 0.0, height: 160.0)
}
}
#available(iOSApplicationExtension 10.0, *)
func widgetActiveDisplayModeDidChange(_ activeDisplayMode: NCWidgetDisplayMode, withMaximumSize maxSize: CGSize) {
if activeDisplayMode == .compact {
preferredContentSize = maxSize
} else {
preferredContentSize = CGSize(width: maxSize.width, height: 200.0)
}
}
/// Makes the widget full size
func widgetMarginInsetsForProposedMarginInsets(defaultMarginInsets: UIEdgeInsets) -> UIEdgeInsets {
return UIEdgeInsets.zero
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func widgetPerformUpdate(completionHandler: (#escaping (NCUpdateResult) -> Void)) {
completionHandler(NCUpdateResult.newData)
}
}

How can I create a button with a background color for tvOS while still showing focus?

All I want to do is add a background color to a button for all states. But I want to maintain the automatic focus shadow that you get "for free" when using a system button in the tvOS storyboard. So far I haven't been able to find a combination that allows this.
Alternatively, I would also be interested in a way to programmatically add the shadow when the button is focused, but short of subclassing the button (which I haven't yet tried), I don't know how to do that either.
Override didUpdateFocusInContext method and check if next focus view is button, if yes then customize its UI, and to set it back to orignal state check context.previousFocusedView was that button, something like below
- (void)didUpdateFocusInContext:(UIFocusUpdateContext *)context withAnimationCoordinator:(UIFocusAnimationCoordinator *)coordinator
{
if (context.nextFocusedView == _button)
{
// set background color
}
else if (context.previousFocusedView == _button)
{
// set background color to background
}
}
You can add a shadow for your custom button like this:
- (void)didUpdateFocusInContext:(UIFocusUpdateContext *)context withAnimationCoordinator:(UIFocusAnimationCoordinator *)coordinator
{
context.nextFocusedView.layer.shadowOffset = CGSizeMake(0, 10);
context.nextFocusedView.layer.shadowOpacity = 0.6;
context.nextFocusedView.layer.shadowRadius = 15;
context.nextFocusedView.layer.shadowColor = [UIColor blackColor].CGColor;
context.previouslyFocusedView.layer.shadowOpacity = 0;
}
Wasn't happy with a simple colour change, so I made a custom button subclass to look more like the default animation you get with system buttons -
class CustomButton: UIButton
{
private var initialBackgroundColour: UIColor!
required init?(coder aDecoder: NSCoder)
{
super.init(coder: aDecoder)
initialBackgroundColour = backgroundColor
}
override func didUpdateFocusInContext(context: UIFocusUpdateContext, withAnimationCoordinator coordinator: UIFocusAnimationCoordinator)
{
coordinator.addCoordinatedAnimations(
{
if self.focused
{
self.backgroundColor = UIColor.whiteColor()
UIView.animateWithDuration(0.2, animations:
{
self.transform = CGAffineTransformMakeScale(1.1, 1.1)
},
completion:
{
finished in
UIView.animateWithDuration(0.2, animations:
{
self.transform = CGAffineTransformIdentity
},
completion: nil)
})
}
else
{
self.backgroundColor = self.initialBackgroundColour
}
},
completion: nil)
}
}
Nothing too complicated, but gets the job done
The Ultimate Solution with inspiration from SomaMan. Just subclass all your custom buttons and you Get this:
includes: on tap animation and release and drag away.
//
// CustomFocusButton.swift
//
import UIKit
class CustomFocusButton: UIButton {
let focusedScaleFactor : CGFloat = 1.2
let focusedShadowRadius : CGFloat = 10
let focusedShadowOpacity : Float = 0.25
let shadowColor = UIColor.blackColor().CGColor
let shadowOffSetFocused = CGSizeMake(0, 27)
let animationDuration = 0.2
override func didUpdateFocusInContext(context: UIFocusUpdateContext, withAnimationCoordinator coordinator: UIFocusAnimationCoordinator)
{
coordinator.addCoordinatedAnimations({
if self.focused{
UIView.animateWithDuration(self.animationDuration, animations:{ [weak self] () -> Void in
guard let weakSelf = self else {return}
weakSelf.transform = CGAffineTransformMakeScale(weakSelf.focusedScaleFactor, weakSelf.focusedScaleFactor)
weakSelf.clipsToBounds = false
weakSelf.layer.shadowOpacity = weakSelf.focusedShadowOpacity
weakSelf.layer.shadowRadius = weakSelf.focusedShadowRadius
weakSelf.layer.shadowColor = weakSelf.shadowColor
weakSelf.layer.shadowOffset = weakSelf.shadowOffSetFocused
},completion:{ [weak self] finished in
guard let weakSelf = self else {return}
if !finished{
weakSelf.transform = CGAffineTransformMakeScale(weakSelf.focusedScaleFactor, weakSelf.focusedScaleFactor)
weakSelf.clipsToBounds = false
weakSelf.layer.shadowOpacity = weakSelf.focusedShadowOpacity
weakSelf.layer.shadowRadius = weakSelf.focusedShadowRadius
weakSelf.layer.shadowColor = weakSelf.shadowColor
weakSelf.layer.shadowOffset = weakSelf.shadowOffSetFocused
}
})
} else {
UIView.animateWithDuration(self.animationDuration, animations:{ [weak self] () -> Void in
guard let weakSelf = self else {return}
weakSelf.clipsToBounds = true
weakSelf.transform = CGAffineTransformIdentity
}, completion: {[weak self] finished in
guard let weakSelf = self else {return}
if !finished{
weakSelf.clipsToBounds = true
weakSelf.transform = CGAffineTransformIdentity
}
})
}
}, completion: nil)
}
override func pressesBegan(presses: Set<UIPress>, withEvent event: UIPressesEvent?) {
UIView.animateWithDuration(animationDuration, animations: { [weak self] () -> Void in
guard let weakSelf = self else {return}
weakSelf.transform = CGAffineTransformIdentity
weakSelf.layer.shadowOffset = CGSizeMake(0, 10);
})
}
override func pressesCancelled(presses: Set<UIPress>, withEvent event: UIPressesEvent?) {
if focused{
UIView.animateWithDuration(animationDuration, animations: { [weak self] () -> Void in
guard let weakSelf = self else {return}
weakSelf.transform = CGAffineTransformMakeScale(weakSelf.focusedScaleFactor, weakSelf.focusedScaleFactor)
weakSelf.layer.shadowOffset = weakSelf.shadowOffSetFocused
})
}
}
override func pressesEnded(presses: Set<UIPress>, withEvent event: UIPressesEvent?) {
if focused{
UIView.animateWithDuration(animationDuration, animations: {[weak self] () -> Void in
guard let weakSelf = self else {return}
weakSelf.transform = CGAffineTransformMakeScale(weakSelf.focusedScaleFactor, weakSelf.focusedScaleFactor)
weakSelf.layer.shadowOffset = weakSelf.shadowOffSetFocused
})
}
}
}
I've found something better:
-(void)didUpdateFocusInContext:(UIFocusUpdateContext *)context withAnimationCoordinator:(UIFocusAnimationCoordinator *)coordinator {
[coordinator addCoordinatedAnimations:^{
if (self.focused) {
self.backgroundColor = [UIColor whiteColor];
}
else {
self.backgroundColor = [UIColor clearColor];
}
} completion:nil];
}
You can use the UIButton method setBackgroundImage(image: UIImage?, forState state: UIControlState) and pass through an image that is a flat color and the state .Normal.
This image can easily be created programatically from a UIColor and a size of 1x1:
func getImageWithColor(color: UIColor, size: CGSize) -> UIImage {
let rect = CGRectMake(0, 0, size.width, size.height)
UIGraphicsBeginImageContextWithOptions(size, false, 0)
color.setFill()
UIRectFill(rect)
let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image
}
You can set the background image in storyboard to an image that contains the color you would like

Collection Node jumping interface

I have collection node. I click on cell node, then I remove all cell nodes exclude one and versa verse. But interface during this operation jumps from one side to another
func animateFolding(for indexPath: IndexPath) {
self.cleanOpportunities()
self.dataSource.append(self.mainDataSource[indexPath.row])
self.node.collectionNode.insertItems(at: [IndexPath(item: 0, section: 0)])
}
func animateExpanding() {
guard self.mainDataSource.count > 1 else {
self.selected = true
return
}
self.cleanOpportunities()
for i in 0..<self.mainDataSource.count {
self.dataSource.append(self.mainDataSource[i])
self.node.collectionNode.insertItems(at: [IndexPath(item: i, section: 0)])
}
self.scrollToStart()
}
public func collectionNode(_ collectionNode: ASCollectionNode, didSelectItemAt indexPath: IndexPath) {
self.selected = !self.selected
self.select(for: indexPath)
}
func cleanOpportunities() {
let count = self.dataSource.count
for i in 0..<count {
let removeIndex = count-i-1
self.dataSource.remove(at: removeIndex)
//self.node.collectionNode.performBatchUpdates({
self.node.collectionNode.deleteItems(at: [IndexPath(item: removeIndex, section: 0)])
//}, completion: nil)
}
}
How to avoid jumping and make smooth folding and expanding cells?

How to create UICollectionView cells with unique background images and UIButtons programmatically

I have created a UICollectionView that uses the same background image for every cell (the cell size is the screen size). How can I set unique background images and buttons for each cell? Please see my code below:
PageCell
import UIKit
class PageCell: UICollectionViewCell {
override init(frame: CGRect) {
super.init(frame: frame)
setupViews()
}
let imageView: UIImageView = {
let iv = UIImageView()
iv.contentMode = .scaleAspectFill
iv.backgroundColor = .yellow
iv.image = UIImage(named: "bg")
iv.clipsToBounds = true
return iv
}()
func setupViews() {
addSubview(imageView)
imageView.anchorToTop(top: topAnchor, left: leftAnchor, bottom: bottomAnchor, right: rightAnchor)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
MenuViewController:
class MenuViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout {
lazy var collectionView: UICollectionView = {
let layout = UICollectionViewFlowLayout()
layout.scrollDirection = .horizontal
layout.minimumLineSpacing = 0
let cv = UICollectionView(frame: .zero, collectionViewLayout: layout)
cv.backgroundColor = .red
cv.dataSource = self
cv.delegate = self
cv.isPagingEnabled = true
return cv
}()
let cellId = "cellId"
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(collectionView)
//use autolayout instead
collectionView.anchorToTop(top: view.topAnchor, left: view.leftAnchor, bottom: view.bottomAnchor, right: view.rightAnchor)
collectionView.register(PageCell.self, forCellWithReuseIdentifier: cellId)
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 4
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellId, for: indexPath as IndexPath)
return cell
}
func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
return CGSize(width: view.frame.width, height: view.frame.height)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
extension UIView {
func anchorToTop(top: NSLayoutYAxisAnchor? = nil, left: NSLayoutXAxisAnchor? = nil, bottom: NSLayoutYAxisAnchor? = nil, right: NSLayoutXAxisAnchor? = nil) {
anchorWithConstantsToTop(top: top, left: left, bottom: bottom, right: right, topConstant: 0, leftConstant: 0, bottomConstant: 0, rightConstant: 0)
}
func anchorWithConstantsToTop(top: NSLayoutYAxisAnchor? = nil, left: NSLayoutXAxisAnchor? = nil, bottom: NSLayoutYAxisAnchor? = nil, right: NSLayoutXAxisAnchor? = nil, topConstant: CGFloat = 0, leftConstant: CGFloat = 0, bottomConstant: CGFloat = 0, rightConstant: CGFloat = 0) {
translatesAutoresizingMaskIntoConstraints = false
if let top = top {
topAnchor.constraint(equalTo: top, constant: topConstant).isActive = true
}
if let bottom = bottom {
bottomAnchor.constraint(equalTo: bottom, constant: -bottomConstant).isActive = true
}
if let left = left {
leftAnchor.constraint(equalTo: left, constant: leftConstant).isActive = true
}
if let right = right {
rightAnchor.constraint(equalTo: right, constant: -rightConstant).isActive = true
}
}
}

Async calling for recording than autoplay than delete the audio

By pressing the button i should record audio for 4 seconds and autoplay it and loop it for 2 times. Another pressing button i should do the same thing but before that i should delete previous record.
Here is my code:
#IBAction func loopButton(_ sender: Any) {
if audioRecorder?.isRecording == false {
playButton.isEnabled = false
audioRecorder?.record(forDuration: 4.0)
audioRecorder?.stop()
audioPlayer?.stop()
do {
try audioPlayer = AVAudioPlayer(contentsOf: (audioRecorder?.url)!)
audioPlayer!.delegate = self
audioPlayer!.prepareToPlay()
audioPlayer!.numberOfLoops = 2
audioPlayer!.play()
} catch let error as NSError {
print("audioPlayer error: \(error.localizedDescription)")
}
} else {
audioRecorder?.deleteRecording()
audioRecorder?.record(forDuration: 4.0)
audioRecorder?.stop()
audioPlayer?.stop()
do {
try audioPlayer = AVAudioPlayer(contentsOf: (audioRecorder?.url)!)
audioPlayer!.delegate = self
audioPlayer!.prepareToPlay()
audioPlayer!.numberOfLoops = 2
audioPlayer!.play()
} catch let error as NSError {
print("audioPlayer error: \(error.localizedDescription)")
}
}
}
I should do this asynchronously, could anyone help me with this?
Thanks
This work's at me, hope it's helpful
#IBAction func loopButton(_ sender: Any) {
DispatchQueue.main.async {
if self.audioRecorder?.isRecording == false {
self.audioRecorder?.record(forDuration: 4.0)
self.playButton.isEnabled = false
} else {
self.audioRecorder?.deleteRecording()
self.audioRecorder?.record(forDuration: 4.0)
self.playButton.isEnabled = false
}
}
DispatchQueue.global().asyncAfter(deadline: .now() + 4.0) {
do {
try self.audioPlayer = AVAudioPlayer(contentsOf: (self.audioRecorder?.url)!)
self.audioPlayer!.delegate = self
self.audioPlayer!.prepareToPlay()
self.audioPlayer!.numberOfLoops = 2
self.audioPlayer!.play()
} catch let error as NSError {
print("audioPlayer error: \(error.localizedDescription)")
}
}
}

ColorSpace Issues Migrating to PDFBox 2.0.x

Our department has inherited code that uses Apache PDFBox 1.8.x or earlier and we are in the process of trying to migrate it to Apache PDFBox 2.0.x.
I have resolved a lot of the various issues in this migration, but I'm still having problems migrating some of the ColorSpace related code. Below are some examples that I haven't figured out how to resolve. I've used the missing methods as the headings for each code snippet.
getColorSpaces() and setColorSpace()
