//例如:
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(50,50,100,40); button.backgroundColor = [UIColor blueColor];
//关键语句 button.layer.cornerRadius = 2.0;//2.0是圆角的弧度,根据需求自己更改 button.layer.borderColor = [UIColor blackColor];//设置边框颜色 button.layer.borderWidth = 1.0f;//设置边框颜色
ios中设置UIButton圆角,添加边框
