NextGrowingTextView

The next in the generations of 'growing textviews' optimized for iOS 8 and above.

As a successor to HPGrowingTextView, NextGrowingTextView was redesigned from scratch to provide the most elegant architecture for iOS 8 and above.

Most autoresizing textviews are implemented with UITextView subclasses. The problem with that approach is that each iOS version changed UITextView's layout behavior, and so most of the implementations are laden with iOS version-specific workarounds to fix bugs and errant behavior. With NextGrowingTextView, the battle with the framework is now over.

NextGrowingTextView approaches the problem differently by wrapping UITextView within a UIScrollView and aligning the textView to the scrollView's contentSize.

- public NextGrowingTextView: UIScrollView
    - internal NextGrowingInternalTextView: UITextView

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

Properties

public class Delegates {
  public var willChangeHeight: (CGFloat) -> Void
  public var didChangeHeight: (CGFloat) -> Void
}

public var delegates: Delegates
public override init(frame: CGRect)

Use isFlashScrollIndicatorsEnabled to enable/disable flash scroll indicators while text view height is less than max height.

Delegates

let growingTextView: NextGrowingTextView

growingTextView.delegates.didChangeHeight = { [weak self] height in
  guard let `self` = self else { return }
  // Do something
}

Requirements

iOS 9.0+ Swift 4.2+
