DAVElopment - Dave's Blog on Coding and Software Development

TLDR: This blog post provides a detailed tutorial on how to implement OmniGroup’s OUIEditableFrame in an iOS project to render text with proper kerning, which cannot be achieved with standard UIKit controls due to a bug. The guide walks through creating and configuring an Xcode workspace, cloning the OmniGroup project from GitHub, adding necessary frameworks and dependencies, and writing the required view controller code.

Instantiating NSDateFormatter objects is slow. Most well-written apps that use NSDateFormatter will make efforts to reduce the number unique instances created.

Wouldn’t it be nice if there was an NSCachedDateFormatter that keeps track of what it has instantiated and will return cached objects and only instantiate new ones when necessary? Wouldn’t it be nice if NSCachedDateFormatter was a singleton and could be used app-wide? Here's a sample class that can be used to fulfill this need.
