iOS View添加边框及圆角

// ViewController.m

// 边框测试

#import "ViewController.h"

@interface ViewController ()

@property (weak, nonatomic) IBOutlet UIImageView *imageView;

@property (weak, nonatomic) IBOutlet UIButton *button;

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

// Do any additional setup after loading the view.

self.imageView.layer.borderWidth = 1;//设置边框大小

self.imageView.layer.borderColor = [UIColor redColor].CGColor;//设置边框颜色

[self.imageView.layer setCornerRadius:10];//设置四个叫都为圆角10

self.button.layer.borderWidth = 1;//设置边框大小

self.button.layer.borderColor = [UIColor redColor].CGColor;//设置边框颜色

self.button.layer.masksToBounds = YES;//是否遮罩边界

CGFloatradius = 10;// 圆角大小

UIRectCorner corner = UIRectCornerBottomLeft | UIRectCornerTopRight; // 圆角位置

UIBezierPath * path = [UIBezierPath bezierPathWithRoundedRect:self.button.bounds byRoundingCorners:corner cornerRadii:CGSizeMake(radius, radius)];

CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];

maskLayer.frame=self.button.bounds;

maskLayer.path= path.CGPath;

self.button.layer.mask= maskLayer;
