Define the global appearance of a view using the Apperance protocol

Suppose you want to define a global bkcolor for the background color

[Email protected] (Nonatomic,strong) Uicolor *bkcolor Ui_appearance_selector;

2. Define the default background color BKCOLR = Redcolor in the following method;

+ (void) initialize{

[CustomView appearance].bkcolor = [Uicolor Redcolor];

}

3. Set the backgroundcolor in the Set method;

-(void) SetBkColor: (Uicolor *) bkcolor{

_bkcolor = Bkcolor;

Self.backgroundcolor = Bkcolor;

}

4: You can use it to set a global property of the view.

[[CustomView appearance] Setbkcolor:[uicolor Yellowcolor]];
