首先新增框架  QuartzCore.framework

在檔案中引入  #import <QuartzCore/QuartzCore.h>

- (void)viewDidLoad

{

    [superviewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

    UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(20, 100,280, 300)];

    myView.backgroundColor = [

    //圓角

    myView.layer.cornerRadius = 6; // 圓角的弧度

    myView.layer.masksToBounds = YES;

    //陰影

    myView.layer.shadowColor = [[UIColorredColor] CGColor];

    myView.layer.shadowOffset = CGSizeMake(5.0f, 5.0f); //[水平偏移, 垂直偏移]

    myView.layer.shadowOpacity = 1.0f; // 0.0 ~ 1.0 的值

    myView.layer

    //邊框

    myView.layer.borderWidth = 2;

    myView.layer.borderColor = [[UIColorblackColor] CGColor];

//漸變光澤

CAGradientLayer *gradient = [CAGradientLayerlayer];

    gradient.frame = myView.bounds;

    gradient.colors = [NSArrayarrayWithObjects:(id)[[UIColorwhiteColor]

    [myView.layer insertSublayer:gradient atIndex:0];

    [self.view addSubview:myView];

    [myView release];

}
