The user interface can be customized in various ways with increasing complexity.


The recommend way to change the appearance of the UI elements is by configuring the Theme. The default is a dark color theme but there is also a predefined light color theme which can be applied as follows:

let configuration = Configuration { builder in
  builder.theme = .light
PESDKConfiguration *configuration = [[PESDKConfiguration alloc] initWithBuilder:^(PESDKConfigurationBuilder * _Nonnull builder) {
  builder.theme = PESDKTheme.light;

The color of specific UI elements can be customized at a central place by modifying the properties of the theme:

let configuration = Configuration { builder in
  builder.theme.backgroundColor = .darkGray
  builder.theme.menuBackgroundColor = .black
  builder.theme.toolbarBackgroundColor = .black
  builder.theme.primaryColor = .green
  builder.theme.tintColor = .red
PESDKConfiguration *configuration = [[PESDKConfiguration alloc] initWithBuilder:^(PESDKConfigurationBuilder * _Nonnull builder) {
  builder.theme.backgroundColor = UIColor.darkGrayColor;
  builder.theme.menuBackgroundColor = UIColor.blackColor;
  builder.theme.toolbarBackgroundColor = UIColor.blackColor;
  builder.theme.primaryColor = UIColor.greenColor;
  builder.theme.tintColor = UIColor.redColor;

Appearance proxies

The theming itself makes heavy use of UIAppearance proxies. The defined colors are applied to most UI elements via UIAppearance proxies during the initialization of a CameraViewController or a PhotoEditViewController. If you need to use UIAppearance proxies yourself you need to issue your calls after the initialization of a CameraViewController or a PhotoEditViewController in order to override the properties set by the theming.

Configuration precedence

The editor UI is divided into different sections. Some members like menuBackgroundColor can be set globally, and if needed locally. That means, that if you set the theme.menuBackgroundColor of the Configuration to black, all tools have that menuBackgroundColor, unless you set another menuBackgroundColor in the specific tool configuration. The following image annotates the most common configuration members. Please note that the background color of the toolbar, which sits at the bottom, is set through a property of the PhotoEditViewController or by theme.toolbarBackgroundColor.

Modifying UI elements via closures takes precedence over the configuration of the theme or the custom use of UIAppearance proxies.
