So, for example, it will soon be possible while composing in iOS to have the color of text change if the app recognizes a specific dynamic element (a hashtag, a Twitter account name, or the like). There are exciting new possibilities hiding behind the labels “Interactive Text Color”, “Text Folding”, and “Custom Truncation”. So what do all these new options mean, practically speaking? Developers can now drop long-form texts into reader-friendly, attractive layouts, with multiple columns and with image layers that aren’t chained to the grid. The bad news: this means existing text-heavy apps will have to be redeveloped in order to support all these nifty new features.Īpple has rebuilt the text layout architecture in iOS 7, allowing developers to build control over the behavior of text and fonts into the user interfaces of their apps, with a level of dynamic freedom unheard-of before. The good news: this means the seamless integration of animation and text (the same principle behind UICollectionView and UITableView) for the first time ever in the history of iOS. To make that possible, Apple has revised UITextView, UITextLabel, and UILabel. ![]() Those settings give developers full control over all Core Text functions, so they can choose very precisely how text will behave in all user interface elements. Text Kit is a fast, modern layout- and text-rendering engine, easy to maintain through settings integrated into the User Interface Kit. But now, no one needs to struggle with it, because Text Kit is there to act as an interpreter. Text Kit is built over Core Text, a sophisticated Unicode layout engine with a lot of power, the potential of which unfortunately hasn’t been very easy to tap in the past. Behind this name is a new API (application programming interface) for developers of apps in which text plays a critical role. In his session, Ian Baird, the person in Cupertino responsible for how Apple’s mobile products handle text, showed off what he called the “coolest feature in iOS 7”: Text Kit. No, text and words aren’t sinking ships in iOS 7. This was largely because of the presentations from Apple’s engineers devoted to ways the OS would handle fonts, in which they revealed the first details of the new technology. People did calm down over the subsequent days of the week-long conference.
