UIView에 그라데이션 적용하기

 

 

- (void)viewDidLoad {
    [super viewDidLoad];

    CAGradientLayer * gradient = [CAGradientLayer new];
    gradient.colors = @[(id)[[UIColor yellowColor] colorWithAlphaComponent:0.6].CGColor,(id)[UIColor redColor].CGColor, (id)[UIColor blueColor].CGColor];
    gradient.locations = @[@0.0f, @0.5f];
    [_gradientView setBackgroundColor:[UIColor clearColor]];
    CALayer * backgroundLayer = gradient;
    backgroundLayer.frame = CGRectMake(_gradientView.bounds.origin.x, _gradientView.bounds.origin.y, self.view.frame.size.width, 240);
    [_gradientView.layer insertSublayer:backgroundLayer atIndex:0];
}
