单击时,Swift,自定义UIButton不起作用 [英] Swift, Custom UIButton does not work when click
问题描述
我有一个用xib文件创建的自定义UIButton。当我在我的视图上使用我的自定义按钮时,按下它时它不起作用。
I have a custom UIButton created with xib file. When i use my custom button on my view, it does not work when i press to it.
我的RoundBtn.swift文件:
My RoundBtn.swift file:
import UIKit
@IBDesignable class RoundBtn: UIButton {
var nibName = "RoundBtn"
@IBOutlet weak var btnImageView: UIImageView!
@IBOutlet weak var btnLabel: UILabel!
@IBInspectable var image: UIImage? {
get {
return btnImageView.image
} set(image) {
btnImageView.image = image
}
}
@IBInspectable var label: String? {
get {
return btnLabel.text
} set(label) {
btnLabel.text = label
}
}
override init(frame: CGRect) {
super.init(frame: frame)
setup()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setup()
}
func setup() {
let view = loadViewFromNib()
view.frame = self.bounds
view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
btnImageView.layer.cornerRadius = 60/2
btnImageView.layer.borderColor = UIColor(red: 5/255,
green: 66/255, blue: 38/255, alpha: 1).CGColor
btnImageView.layer.borderWidth = 2
btnLabel.font = UIFont.boldSystemFontOfSize(14.0)
btnImageView.userInteractionEnabled = true
btnLabel.userInteractionEnabled = true
view.userInteractionEnabled = true
addSubview(view)
}
func loadViewFromNib() -> UIButton {
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: nibName, bundle: bundle)
let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIButton
return view
}
}
我的RoundBtn.xib档案:
My RoundBtn.xib file:
查看我使用自定义按钮的位置:
View where i used my custom button:
我已启用所有视图组件上的userInteractionEnabled
。当我点击我的自定义按钮时,它不起作用。我尝试通过编程方式定义单击并定义动作segue(show)。
I enabled userInteractionEnabled
on all view components. When i click to my custom button, it does not work. I tried by defining on click programmatically and by defining action segue (show).
@IBAction func myCartBtnPressed(sender: AnyObject) {
print("my cart btn pressed")
}
推荐答案
我认为这是因为您使用userInteractionEnabled向当前的UIButton添加了几个UIViews子视图,这意味着他们正在处理用户输入。
I think this is caused because you're adding a couple of UIViews subviews to your current UIButton with userInteractionEnabled, which means that they're handling the user input.
如果你这样做:
view.isUserInteractionEnabled = false
RoundBtn本身将获得所有触摸事件,而不是您拥有的UIViews。
The RoundBtn itself will get all the touch events, instead of this UIViews that you have on top.
