How to change button text in Swift Xcode 6?
提问by GuavaMantis
Here's what I'm trying to do. If you've ever played Halo or CoD, you'd know that you could change the name of a weapon load-out.
这就是我想要做的。如果您曾经玩过 Halo 或 CoD，您就会知道您可以更改武器装载的名称。
What I'm doing is making it so you can change your load-out name using a text field. Here's the problem, the load-out name in the load-out menu is a button (to select and view info about that load-out) and I could just write this:
我正在做的是制作它，以便您可以使用文本字段更改加载名称。问题是，加载菜单中的加载名称是一个按钮（用于选择和查看有关该加载的信息），我可以这样写：
@IBAction func renameClassButton(sender: AnyObject) {
classTopButton.text = "\(classTopTextField)"
}
Except it [classTopButton] is a button which doesn't allow the '.text' suffix
除了它 [classTopButton] 是一个不允许 '.text' 后缀的按钮

It is now this For swift 3,
现在是这样 对于 swift 3，
let button = (sender as AnyObject)
button.setTitle("Your text", for: .normal)
(The constant declaration of the variable is not necessary just make sure you use the sender from the button like this) :
（变量的常量声明不是必需的，只需确保您像这样使用按钮中的发送者）：
(sender as AnyObject).setTitle("Your text", for: .normal)
Remember this is used inside the IBAction of your button.
请记住，这是在按钮的 IBAction 中使用的。

You can Use sender argument
您可以使用发件人参数
@IBAction func TickToeButtonClick(sender: AnyObject) {
sender.setTitle("my text here", forState: .normal)
}

Note that if you're using NSButton there is no setTitlefunc, instead, it's a property.
请注意，如果您使用的是 NSButton，则没有setTitlefunc，而是一个属性。
@IBOutlet weak var classToButton: NSButton!
. . .
classToButton.title = "Some Text"

In Swift 4 I tried all of this previously, but runs only:
在 Swift 4 中，我之前尝试了所有这些，但仅运行：
@IBAction func myButton(sender: AnyObject) {
sender.setTitle("This is example text one", for:[])
sender.setTitle("This is example text two", for: .normal)
}

someButton.setTitle("New Title", forState: .normal)
works only when Title type is Plain.
仅当 Title 类型为Plain时才有效。
