In UIView, there is a method called prepareForInterfaceBuilder, which does exactly what it says on the tin – override the method to set properties only relevant in Interface Builder. PaintCode really shines when you have to change individual image layers at runtime. PaintCode then allows you to export these graphics as StyleKits: generated Objective-C or Swift code that, instead of describing shapes using SVGs declarative. Luckily, that exists, as I found out later. What I needed was a way to set a property, but only from within Interface Builder. Make the property This only works with relatively simple values though (strings, numbers, colors), and it has the same problem as the above.This is a bit dangerous though forget to reset or unset this property at runtime and your user will be stuck with some default placeholder, or worse, flat-out wrong information. Set a default value, to be overridden at runtime.Some view modifiers can take a color as an argument. Use one of a palette of predefined colors, like black, green, and purple. link) elseif os (macOS) let linkColor Color(nsColor. One case I had to deal with is an UIView that can draw a selection of StyleKit images, depending on the value of a dynamic model value. I considered a few options to deal with that: Create a color instance from another color, like a UIColor or an NSColor: if os (iOS) let linkColor Color(uiColor. Let’s make it Xebia purple, to please the boss Save the file, then export it to your xcode project in the language of your choice. Add a frame around it, and set the constraints to variable so it will adjust to the size of the frame (drag the frame corners around within PaintCode to confirm). Let’s draw a nice envelope or email icon.

I will also go into setting colors, and finally about how to deal with views that depend on dynamic runtime data to draw themselves.įirst, let’s create a simple graphic in PaintCode. In this blog I will explain an effective and simple method to draw PaintCode graphics in a way where you can see what you’re doing in Interface Builder, using the relatively new annotation. One thing that I personally struggled with for a while now was how to use them effectively in combination with Interface Builder, the UI development tool for iOS and OSX apps. The benefits of this are vastly reduced app installation size – no need to include three resolutions of the same image for every image – and seamlessly scalable graphics. If your font hasn’t been designed with font width in mind, you’ll just get the default width.Every self-respecting iOS developer should know about PaintCode by now, an OSX app for drawing graphics that don’t save as images, but as lengths of code that draw graphics. Note: You will find that fontWidth() only works with fonts that have been designed to support it. Or use the fontWidth() modifier to compress or expand the font, like this: Text("Hello, world!") You can also use the fontDesign() modifier to adjust only the style of the font without also adjusting its size, like this: Text("Hello, world!") The default value is 0, which means there is no extra line spacing applied, but you can also specify position values to add extra spacing between lines: Text("This is an extremely long text string that will never fit even the widest of phones without wrapping") For example, we can adjust the line spacing in our text. This is because SwiftUI lets us recolor text however we want, but it must always be a simple color, whereas you can place any kind of view in the background – a color, yes, but also a shape, some other text, and more. Tip: You might wonder why foregroundColor() has color in the name, whereas background() does not. Anyway, to give our layout a yellow background color we would add this: Text("The best laid plans") background() because it’s possible to use more advanced backgrounds than just a flat color. You can also set the background color, but that uses.

using a gradient, you should use foregroundStyle() like this: Text("The best laid plans") foregroundColor() modifier, like this: Text("The best laid plans")įor more complex text coloring, e.g. We can control the color of text using the. font() on it like this: Text("This is an extremely long text string that will never fit even the widest of phones without wrapping") Not only do text views give us a predictably wide range of control in terms of how they look, they are also designed to work seamlessly alongside core Apple technologies such as Dynamic Type.īy default a Text view has a “Body” Dynamic Type style, but you can select from other sizes and weights by calling. How to style text views with fonts, colors, line spacing, and more
