问题描述
我正在以编程方式创建一个按钮,我想知道如何设置该按钮的 UIButtonType.
I am creating a button programatically and I would like to know how to set that button's UIButtonType.
这就是我创建按钮的方式:
This is how I am creating my button:
let headerPlusButon:UIButton = UIButton(frame: CGRectMake(5, tableView.frame.width - 30, 20, 20))
headerPlusButon.addTarget(self, action: "paymentAddButtonTapped", forControlEvents:.TouchUpInside)
没有像更改标题文本那样的setButtonTypeFor..."方法,显然这不起作用:
There is no "setButtonTypeFor..." method like how you would change the title's text and obviously this doesn't work:
headerPlusButon.buttonType = UIButtonType.ContactAdd
推荐答案
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton.buttonWithType(UIButtonType.System) as UIButton
button.frame = CGRectMake(100, 100, 100, 50)
button.backgroundColor = UIColor.greenColor()
button.setTitle("Test Button", forState: UIControlState.Normal)
button.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(button)
}
func buttonAction(sender:UIButton!)
{
println("Button tapped")
}
从 swift 2
用下面的行替换 UIButton
声明.
from swift 2
replace UIButton
declaration with below line.
let button = UIButton(type: .System) as UIButton
