phlippieb / MaxHeightTextView.swift
Created January 25, 2017 05:35
`MaxHeightTextView` overrides `UITextView`'s `intrinsicContentSize` and `layoutSubviews` to allow it to grow to fit its content size, but only up to a specified max height. Once the text view reaches this max height, its content will start to scroll. Use with AutoLayout. Specifically, set up a fixed width, and two height constraints with greater…

phlippieb / RangeTappableTextView.swift
Last active November 23, 2016 14:00
A UITextView subclass that allows clients to register ranges of characters as "tappable", with keys to identify those ranges. A delegate can be assigned to receive callbacks when tappable ranges are tapped. When a user taps on a character in the text view which is in a registered range (with a registered key), the delegate's callback is called w…

phlippieb / stringFuzzilyContains.md
Last active November 19, 2016 11:23

This naive algorithm compares two strings, needle and haystack. It returns true if haystack "fuzzily" contains needle, which is when (almost) every character in needle is found in (almost) the same order, but not necessarily contiguously, in haystack. Up to allowed_errors characters in needle are allowed to not be found in haystack. Characters may also be swapped.

The following is a python implementation:

def stringFuzzilyContains(needle, haystack):
    # allow this many characters to not be found
    allowed_errors = 0
    
    # the last index where a character was found;

Last active August 24, 2016 06:58
A swift autocomplete solution. I needed this to subclass a specific textview class (from the Material pod, if you're interested), but it should work fine with UITextView. I also used RxSwift to capture text changes, which can probably be done with the text view's delegate methods, though it might be harder.
