1. gradient effect-> color space

 

First: Customize a gradient view and rewrite drawRect in the Custom view.

# Import "ViewController. h "# import" MyView. h "@ interface ViewController () @ end @ implementation ViewController-(void) viewDidLoad {[super viewDidLoad]; MyView * view = [[MyView alloc] initWithFrame: self. view. bounds]; [self. view addSubview: view];}

Next, we will take five steps.

 

2. gradient effect-> linear gradient

The steps are the same as above!
