I am a beginner in swift. I have
class A : UIViewController { var textInput: UITextInput init(textInput: UITextInput) { self.textInput = textInput } func getText() -> String() { /// Here I need to get the current text from textInput } } How to get it ? Help please. Thanks in advance!!!!
Swift 3:
let start = sender.beginningOfDocument let end = sender.endOfDocument let range = sender.textRange(from: start, to: end)! let trimmedText = sender.text(in: range) sender.replace(range, withText: "new text") I got it.
let start: UITextPosition = self.textInput.beginningOfDocument let end: UITextPosition = self.textInput.endOfDocument let range: UITextRange = textInput!.textRangeFromPosition(start!, toPosition: end!)! textInput!.textInRange(range!) // for get text textInput.replaceRange(range!, withText: "some text") // to write text import Foundation import UIKit public extension UITextInput { public var text: String { get { text(in: textRange(from: beginningOfDocument, to: endOfDocument)!) ?? "" } set(value) { replace(textRange(from: beginningOfDocument, to: endOfDocument)!, withText: value) } } } Your textInput variable is never declared properly. You might want to consider learning more general practices of Swift before asking specific questions.
Proper declaration of textInput would look like:
class A : UIViewController { var textInput: UITextInput 
UITextField and get the text with textInput.text?UITextField?
