Not quite equilateral but as close as you’re likely to get with character graphics. The main things are that you need an odd number of asterisks on each line for centering to work and you need to calculate an offset.

Let’s start with this string : let abc : String = “aaaabbbbbbbccddde” And have the output in a new variable var result = “” Let’s use an index to go through the characters in the string var index = abc.startIndex while index < abc.endIndex { //There is already one character : let char = abc[index] … Read more
You’ll want to use the UIBarButtonItem constructor init(image: UIImage?, style: UIBarButtonItemStyle, target: Any?, action: Selector?) an example usage would be: self.navigationItem.leftBarButtonItem = UIBarButtonItem(image: UIImage(named: “burger_icon”), style: .plain, target: self, action: #selector(self.someMethod)) In this example “burger_icon” is the name of the image asset in your project and self.someMethod is the method that is called when this … Read more

You can use custom delegate method to fill the value. class PopupviewController { weak var delegate: filleTextViewDelegate? func calldelegate () { delegate?.fillTextview(filledData) } } protocol filleTextViewDelegate : class { func fillTextview(filledData: String) } class CurrentViewController :filleTextViewDelegate { func fillTextview(filledData: String) { textView.text = filledData } } solved Swift, Pass data from popover controller to previous … Read more
You can add two collection view in a single view controller by dragging it. but you have to validate UIcollection view like func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell { var cell = HomeCollectionViewCell() if(collectionView == self.collName1) { cell = collName.dequeueReusableCellWithReuseIdentifier(“CellIdentifier”, forIndexPath: indexPath) as! HomeCollectionViewCell } else if(collectionView == self.collName2) {} return cell } … Read more
if true condition is always satisfied. You should modify your userInput() method to return a boolean value, if you want to use it. func userInput() -> Bool { return Util.shared.isPalindrome(word: word) } And then handle the result: if userInput() { // do something } else { // do something else } solved Why is the … Read more
