Description

In iOS development, UIImage.RenderingMode is an enumeration used to define how images are rendered when drawn on the screen. Here are the main rendering modes provided by UIImage:

.automatic:

• This is the default mode. The system automatically determines how to render the image based on the context.
• Typically, it will render template images in a way that they can adapt to different color styles, such as when used in navigation bars, tab bars, and buttons. If the image has an alpha channel, it may use a tint color.
• If the image does not have an alpha channel or is not marked as a template image, it will render the original image.

.alwaysOriginal:

• This mode renders the image as it is, without applying any modifications like tint color.
• It's useful when you want to display the image in its original form, regardless of where it's used.
• For example, if you have an icon with specific colors that you want to remain unchanged when placed in a button or tab bar, you should use .alwaysOriginal.

.alwaysTemplate:

• This mode treats the image as a template, meaning that the image will be rendered using the tint color provided by the view it's displayed in.
• It's commonly used for icons in toolbars, tab bars, or buttons where you want the icon to adopt the tint color of the control (e.g., to match the app's theme or user-selected appearance).
• For example, if you set an image view's tintColor to red, an image with .alwaysTemplate will render in red.
