How to add an icon to a standard UIButton?

Question

Can I add a standard icon to the UIButton standard?

If this is not supported semi-linearly, what would be the easiest way to achieve this?

Image example:

Answer 1

Here's a VERY LOW Sascha Paulus class called CustomBadge , which creates and displays custom icons using Core Graphics. These are just subclasses of UIView, so you use them with your frame like any other subclass of UIView.

I have used this library many times and have always been pleased with the results. Flexible, easy to use. I totally recommend it.

Answer 2

Here you can check several options: CocoaControls Icons

Answer 3

The class that Apple uses is _UIBadgeView ( https://github.com/nst/iOS-Runtime-Headers/blob/master/Frameworks/UIKit.framework/_UIBadgeView.h ), but of course this class is private (reverse attention to underlining) and are not documented.

Here is another class that implements this view with the same appearance and feel as Apple, and also allows you to customize it: https://github.com/JaviSoto/JSBadgeView . The great thing about this is that it allows you to automatically position the icon in relation to another view in one of its corners.

Answer 4

We have an icon in Nimbus that is very easy to use and well documented:

Nimbus badge

Answer 5

I do not know how this is done out of the box, and I honestly doubt that Apple built it in the SDK.

In any case, you can create your own view using the button on it, add the background of the icon as a UIImageView and place a label on it to hold the icon counter.

This quick fix, it might be better to create a custom UIButton subclass and add your icon material as a preview

Answer 6

I would do the same as @ Björn Kaiser: use the button as you like, and then add a custom view with this icon as a subroutine to it - I did it and it works fine.

As for the view, you can draw it as you wish. You can draw it by hand or use CoreAnimation and let it do the main part, i.e. theBadge.layer.cornerRadius = ...; to give it a round shape, draw text / number in drawRect: or add it as a label, etc.
