The design for a recent project called for the contents of the popover view to be emphasized prominently. Specifically, the design wanted all the views behind the popover to be dimmed. By default, iOS will put a radial gradient around the popup to draw attention to it, but I needed something more. In this blog […]
The seventh item in my Swift Tool Belt is an extension for UIBarButtonItem. This extension will add a couple of inspectable properties to help you set accessibility properties from Xcode’s interface builder. They also add the ability to hide a bar button item.
The sixth item in my Swift Tool Belt is an extension for UIFont. This extension will easily convert your font to be bold or italic. It can be useful if you use scaled fonts but need a different look.
The fifth item in my Swift Tool Belt is a class derived from UIButton that will draw your button with a gradient background. It will also expose the colors of your gradient in the attributes inspector of Xcode and render the gradient button directly in your storyboard.
The fourth item in my Swift Tool Belt is an extension for UITableViewController. A UITableViewController is a view controller with a table view that takes up the entire screen. My extension provides a couple of methods to resize the header and footer of a table view.
The third item in my Swift Tool Belt is a couple of extensions on UILabel. These extensions will allow easy access to modify the edge insets on a label (the extra padding all around the text). There’s also an extension to add a rotation transform to a label. All of these extensions will be IBDesignable […]
The second item in my Swift Tool Belt is an extension on the Date class. The interface to the Date class in iOS is very powerful, but in my opinion, it is not very readable. Simple operations to add/remove time to a date can be several lines long. Many of my extensions help with the […]
During my iOS work, I’ve assembled a set of code that I bring with me on every iOS project. I’m not talking about large frameworks or CocoaPods here. These are smaller Swift extensions or control overrides that are applicable to many projects. I think of them as my tool belt.
There are two different ways to add cells to a UITableView. The first is by using dynamic prototype cells in your table view. For a dynamic table view, you programmatically arrange the cells and sections of the table view by implementing the UITableViewDataSource protocol in code. Using this method, you can display a variable number of […]
Before I developed for iOS, I did a lot of Microsoft WPF programming. One of the layouts available on that platform was a WrapPanel. Microsoft’s WrapPanel is similar to Apple’s UIStackView in that it arranges child elements into a single line that can be oriented horizontally or vertically. There are many differences, but the one I […]
