提问by Daniele B
I would like to make a UILabel clickable.
我想让 UILabel 可点击。
I have tried this, but it doesn't work:
我试过这个，但它不起作用：
class DetailViewController: UIViewController {
@IBOutlet weak var tripDetails: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
...
let tap = UITapGestureRecognizer(target: self, action: Selector("tapFunction:"))
tripDetails.addGestureRecognizer(tap)
}
func tapFunction(sender:UITapGestureRecognizer) {
print("tap working")
}
}

Have you tried to set isUserInteractionEnabledto trueon the tripDetailslabel? This should work.
您是否尝试在标签上设置isUserInteractionEnabled为？这应该有效。truetripDetails

Swift 3 Update
斯威夫特 3 更新
Replace
代替
Selector("tapFunction:")
with
和
#selector(DetailViewController.tapFunction)
Example:
例子：
class DetailViewController: UIViewController {
@IBOutlet weak var tripDetails: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
...
let tap = UITapGestureRecognizer(target: self, action: #selector(DetailViewController.tapFunction))
tripDetails.isUserInteractionEnabled = true
tripDetails.addGestureRecognizer(tap)
}
@objc
func tapFunction(sender:UITapGestureRecognizer) {
print("tap working")
}
}

Similar to @liorco, but need to replace @objcwith @IBAction.
到@liorco，但需要类似的更换@objc与@IBAction。
class DetailViewController: UIViewController {
@IBOutlet weak var tripDetails: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
...
let tap = UITapGestureRecognizer(target: self, action: #selector(DetailViewController.tapFunction))
tripDetails.isUserInteractionEnabled = true
tripDetails.addGestureRecognizer(tap)
}
@IBAction func tapFunction(sender: UITapGestureRecognizer) {
print("tap working")
}
}
This is working on Xcode 10.2.
这适用于 Xcode 10.2。

Good and convenient solution:
好用又方便的解决方法：
In your ViewController:
在您的 ViewController 中：
@IBOutlet weak var label: LabelButton!
override func viewDidLoad() {
super.viewDidLoad()
self.label.onClick = {
// TODO
}
}
You can place this in your ViewController or in another .swift file(e.g. CustomView.swift):
你可以把它放在你的 ViewController 或另一个 .swift 文件中（例如 CustomView.swift）：
@IBDesignable class LabelButton: UILabel {
var onClick: () -> Void = {}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
onClick()
}
}
In Storyboard select Label and on right pane in "Identity Inspector" in field class select LabelButton.
在 Storyboard 中选择 Label，然后在字段类中的“Identity Inspector”的右侧窗格中选择 LabelButton。
Don't forget to enable in Label Attribute Inspector "User Interaction Enabled"
不要忘记在标签属性检查器中启用“启用用户交互”

For e.g
例如
yourLabel.userInteractionEnabled = true
yourLabel.userInteractionEnabled = true

For swift 3.0 You can also change gesture long press time duration
对于 swift 3.0 您还可以更改手势长按持续时间
label.isUserInteractionEnabled = true
let longPress:UILongPressGestureRecognizer = UILongPressGestureRecognizer.init(target: self, action: #selector(userDragged(gesture:)))
longPress.minimumPressDuration = 0.2
label.addGestureRecognizer(longPress)

Pretty easy to overlook like I did, but don't forget to use UITapGestureRecognizerrather than UIGestureRecognizer.
像我一样很容易忽略，但不要忘记使用UITapGestureRecognizer而不是UIGestureRecognizer.

As described in the above solution you should enable the user interaction first and add the tap gesture
如上述解决方案中所述，您应该首先启用用户交互并添加点击手势
this code has been tested using

yourlabel.isUserInteractionEnabled = true
yourlabel.addGestureRecognizer(UITapGestureRecognizer(){
//TODO
})
