UIAlertController Changes in iOS 8
As part of the theme of iOS 8 to make interfaces adaptive there are some major changes to the presentation of view controllers. The new UIPresentationController does a lot of the hard work of animating view controller transitions and adapting to device size changes such as rotation. It also brings some big changes to some old UIKit favourites such as alert views, action sheets, popovers and search
Self Sizing Table View Cells
Last updated: Jun 12, 2020 It only took five years but this is much easier to do with Interface Builder in Xcode 11. See Self Sizing Table View Cells in Interface Builder Dynamic Type Everywhere I covered the basics of supporting dynamic type some time ago. Introduced in iOS 7, dynamic type allows the user to specify a preferred reading size for text. In the upcoming release of iOS 8 the Apple int
Running Custom Clang Analyzer Builds
I don’t remember where I first saw this mentioned so I cannot give proper credit but this is an interesting tip to try if you have five minutes. Open Source Builds of the Clang Analyzer The Clang Static Analyzer has long been integrated with Xcode and provides powerful source code analysis to detect bugs in C, C++ and Objective-C code. The analyzer is fully open source and part of the larger Clang
Using Launch Arguments To Test Localizations
A quick tip for switching between localizations when testing. Updated 28-December-2013 to include details on setting the locale Changing the Language Settings If you have done any work with localizing an application I am sure you are familiar with changing the language of the simulator or a device from the Settings app: Changing this setting back and forth between the different languages you need
Xcode 4.6 Recommended Build Settings
Xcode 4.6 introduced a number of additional compiler warnings that are enabled by default for new projects. Unfortunately the release notes are none too clear about the new options: LLVM: New compiler warnings to help find subtle behavioral bugs when using automatic release counting (ARC) and weak references. If you have an existing project you can update to the new recommended build settings from
Remote Packet Capture for iOS devices
I previously posted about using the Network Link Conditioner to create realistic and “challenging” network conditions when testing iOS apps. In this post I want to highlight another useful network debugging tool which allows you capture network traffic from an iOS device. Remote Virtual Interfaces As with the Network Link Conditioner you need to use a host Mac computer to perform remote packet cap
Using Appearance Proxy To Style Apps
In a previous post I examined how with iOS 5 it became much easier to customise the appearance of some common UIKit controls using resizable images. In this post I want to go a little further and look at how to use appearance proxies to more fully style an applications user interface. I should mention that I am writing this post a few weeks ahead of the expected release of iOS 6. This discussion i
Using Number Formatters
The NSNumberFormatter is one of those useful Foundation classes that is easy to forget about. It has a simple purpose of allowing you to flexibly convert backwards and forwards between numbers (NSNumber) and localised string (NSString) representations of those numbers. This post is a collection of quick notes for some of the most common uses when converting a number to a string. NSNumberFormatterS
Prototype Table Cells and Storyboards
I recently posted on creating static table views with storyboards. In this post I want to look at some other changes introduced with iOS 5 to make it easier to create dynamic table views. An Example Of Custom Table View Cells For the purposes of this discussion I am going to use an example App which consists of a single table view. The App is named WorldFacts and can be found in my Code Examples g
Static Table Views with Storyboards
When I first heard that iOS 5 had introduced the concept of a static table view that could be designed in Interface Builder I was disappointed to see that it was actually tied into storyboards. I have nothing against storyboards, they are an interesting innovation that can (potentially) save a lot of code. However if you are not yet ready to fully adopt storyboards for your user interface design y
UIAlertView changes in iOS 5
Update 05-Sep-2014: See this later post on UIAlertController Changes in iOS 8 for a modern replacement of UIAlertView if you target iOS 8 or later. The UIAlertView class has been available since iOS 2. It is similar to the UIActionSheet class but generally the UIAlertView is used to display an alert message to the user whereas UIActionSheet is useful when you want the user to confirm or choose bet
