IOS navigation bar style

 

The navigation controller can display itself in several different styles. The default style is the standard gray appearance. Currently, three different styles are supported.

Fengge	Description
Uibarstyledefault	Default style; gray background, white text
Uibarstyleblack	Black background, white text
Uibarstyleblackopaque	Black background, white text
Uibarstyleblacktranslucent	Transparent black background, white text

The style is set through the barstyle attribute. This attribute belongs to the navigation controller rather than the View Controller. Therefore, this attribute can be consistent during back-and-forth switching between views:

Self. navigationcontroller. navigationbar. barstyle = uibarstyleblacktranslucent;

The original IOS documents are as follows:

Uibarstyle
Defines the stylistic appearance of different types of views.

Typedef Enum {
Uibarstyledefault = 0,
Uibarstyleblack = 1,
 
Uibarstyleblackopaque = 1, // deprecated
Uibarstyleblacktranslucent = 2, // deprecated
} Uibarstyle;
