declare your button:
Code:
UIButton *downButton = [[UIButton alloc] initWithFrame:CGRectMake(60.0, 310.0, 55.0, 37.0)];
[downButton setTitle:@"Name of Button" forState:UIControlStateNormal];
[downButton setTitleColor:[UIColor blackColor] forState:UIControlEventTouchDown];
[downButton.titleLabel setFont:[UIFont fontWithName:@"Times New Roman" size: 8]];
[downButton addTarget:self action:@selector(downButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
[downButton setBackgroundColor:[UIColor darkGrayColor]];
[downButton setTag:89];
then add:
Code:
CALayer * downButtonLayer = [downButton layer];
[downButtonLayer setMasksToBounds:YES];
[downButtonLayer setCornerRadius:10.0];
[downButtonLayer setBorderWidth:1.0];
[downButtonLayer setBorderColor:[[UIColor grayColor] CGColor]];
[self.view insertSubview:downButton atIndex:upButton.tag];
[downButton release];
The key code is
setBorderWidth: Adapt as necessary... but note the border is manipulated prior to adding to as subview.
Also, make sure you:
Code:
#import "QuartzCore/QuartzCore.h" // for CALayer
into your .m file...

注意：
1、首先要定义一个button 按钮，button的tag属性一定要设置好。。。才能进行第二步的操作
2、其次加入CALayer代码
3、导入框架quartzCore.framework
拓展：
imageview 也可以用这种方法来为图片设置边框和边框的颜色
