一、概念

/**

UIView 的左上角和右上角為圓角

UIButton左上角和右上角圓角

注意:直接拷貝方法直接可以使用

二、UIView 的左上角和右上角為圓角

效果圖:

????????????????????????????????????????????????? UIView 的左上角和右上角為圓角

聲明:

@property(nonatomic,strong) UIView *platFormRadiusView;

- (void)viewDidLoad {

? ? [super viewDidLoad];

? ? self.title = @"左上和右上為圓角";

? ? [self platFormRadiusView];

}

實現(xiàn):

-(UIView *)platFormRadiusView{

? ? if (!_platFormRadiusView) {

? ? ? ? _platFormRadiusView = [[UIView alloc] init];

? ? ? ? _platFormRadiusView.backgroundColor = [UIColor redColor];

? ? ? ? _platFormRadiusView.frame = CGRectMake(0, 100,self.view.frame.size.width , 200);

? ? ? ? [self.view addSubview:_platFormRadiusView];

? ? ? ? // 左上和右上為圓角

? ? ? ? UIBezierPath *cornerRadiusPath = [UIBezierPath bezierPathWithRoundedRect:_platFormRadiusView.bounds byRoundingCorners:UIRectCornerTopRight | UIRectCornerTopLeft cornerRadii:CGSizeMake(15, 15)];

?? ? ? ?

? ? ? ? CAShapeLayer *cornerRadiusLayer = [ [CAShapeLayer alloc ] init];

? ? ? ? cornerRadiusLayer.frame = _platFormRadiusView.bounds;

? ? ? ? cornerRadiusLayer.path = cornerRadiusPath.CGPath; _platFormRadiusView.layer.mask = cornerRadiusLayer;

? ? }

? ? return _platFormRadiusView;

}

三、UIButton 的左上角和右上角為圓角

效果圖:

?????????????????????????????????????????????? UIButton 的左上角和右上角為圓角

- (void)viewDidLoad {

? ? [super viewDidLoad];

?? ?self.title = @"Button左上和右上為圓角";

? ? [self platFormRadiusButton];

}

實現(xiàn):

-(void)platFormRadiusButton{

?? ?UIButton *shButton = [UIButton buttonWithType:UIButtonTypeCustom];

? ? shButton.frame = CGRectMake(0, 100, self.view.frame.size.width, 200);

? ? shButton.backgroundColor = [UIColor redColor];

? ? [shButton setTitle:@"石虎測試Button" forState:0];

? ? shButton.tag = 1;

? ? [self.view addSubview:shButton];

? ? //設(shè)置圓角

?UIBezierPath?*maskPath = [UIBezierPath bezierPathWithRoundedRect:shButton.bounds byRoundingCorners:UIRectCornerTopRight | UIRectCornerTopLeft cornerRadii:CGSizeMake(15, 15)];

?? ?

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

? ? maskLayer.frame = shButton.bounds;

? ? maskLayer.path = maskPath.CGPath;

? ? shButton.layer.mask = maskLayer;

}

謝謝!!!
