如何批量给uibutton设置边框圆弧等

方法如下：

UIButton *signBtn = [UIButton buttonWithType:UIButtonTypeCustom]

signBtn.frame = CGRectMake(0, 0, 80, 40)

[signBtn.layer setMasksToBounds:YES]

[signBtn.layer setCornerRadius:10.0]

//设置矩形四个圆角半径

[signBtn.layer setBorderWidth:1.0]

//边框宽度

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB()

CGColorRef colorref = CGColorCreate(colorSpace,(CGFloat[]){ 1, 0, 0, 1 })

[signBtn.layer setBorderColor:colorref]

//边框颜色.

看一下效果图，类似于淘宝加入购物车，我用的是UIButton

颜色颜色Button和型号一样：

1.创建UIButton

for (int i = 0i <6i++) {

        self.selectColorBtn = [UIButton buttonWithType:UIButtonTypeCustom]

        if (i >4) {

        self.selectColorBtn.frame = CGRectMake(70 * widthScale + 60 * widthScale * (i-5)  , 50 * widthScale, 50 * widthScale, 30 *widthScale)

        }else{

        self.selectColorBtn.frame = CGRectMake(70 * widthScale + 60 * widthScale * i  , 10 * widthScale, 50 * widthScale, 30 *widthScale)

        }

        [self.selectColorBtn setTitle:@"暗灰色" forState:UIControlStateNormal]

        [self.selectColorBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]

        self.selectColorBtn.tag = 100 + i

        self.selectColorBtn.titleLabel.font = [UIFont systemFontOfSize:15 * widthScale]

        [self.selectColorBtn.layer setBorderWidth:1.0]

        [self.selectColorBtn.layer setBorderColor:[gray CGColor]]

        [self.selectColorBtn addTarget:self action:@selector(selectColorAction:) forControlEvents:UIControlEventTouchUpInside]

        

        [self.twoView addSubview:self.selectColorBtn]

        

        

    }

2.按钮点击事件

- (void)selectColorAction:(UIButton *)btn{

//将Button颜色全部修改为灰色

for (int i = 0i <6i++) {

//通过tag值获取UIbutton

UIButton *btn = (UIButton *)[self.twoView viewWithTag:100 + i]

        [btn.layer setBorderColor:[gray CGColor]]

    }

//获取当前UIButton

UIButton *nowBtn = btn

    switch (btn.tag) {

        case 100:

         

        [nowBtn.layer setBorderColor:[ThemeColors CGColor]]

            break

        case 101:

            [nowBtn.layer setBorderColor:[ThemeColors CGColor]]

            break

        case 102:

           

            [nowBtn.layer setBorderColor:[ThemeColors CGColor]]

            break

        case 103:

            [nowBtn.layer setBorderColor:[ThemeColors CGColor]]

            break

        case 104:

            [nowBtn.layer setBorderColor:[ThemeColors CGColor]]

            break

        case 105:

            [nowBtn.layer setBorderColor:[ThemeColors CGColor]]

            break

        default:

            break

    }

UIButton *button = [UIButton alloc] initWithFrame:CGRect(100, 100, 100 , 100)]

   //设置边框颜色

   button.layer.borderColor = [[UIColor redColor] CGColor]

  //设置边框宽度

   button.layer.borderWidth = 1.0f

   //给按钮设置角的弧度

   button.layer.cornerRadius = 4.0f 

  //设置背景颜色

   button.backgroundColor = [UIColor redColor]

   button.layer.masksToBounds = YES
