我已经从xib(自由格式)创建了一个自定义视图,其中有两个按钮(登录和取消),我根据某些条件在视图中显示它。自定义视图很好地出现在另一个视图上但是按钮(登录取消)没有得到任何触摸事件。
自定义类和init方法的代码:
import UIKit
class customAlertView: UIView {
@IBOutlet weak var messageLabel: UILabel!
@IBOutlet weak var loginButton : UIButton!
@IBOutlet weak var cancelButton: UIButton!
var view : UIView!
override init(frame: CGRect) {
super.init(frame: frame)
view = setUpFromXib()
view.frame = frame
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
func setUpFromXib() -> UIView {
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "customAlertView", bundle: bundle)
let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
addSubview(view)
translatesAutoresizingMaskIntoConstraints = true
return view
}
@IBAction func loginButtonAction(sender: AnyObject) {
}
@IBAction func cancelButtonAction(sender: AnyObject) {
}
}
这是我将自定义视图添加为子视图的代码块。
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if Reachability.isConnectedToNetwork() {
categoryObj = categoryArray .objectAtIndex(indexPath.row) as! TECategoryDetails
if categoryObj.categoryType == "premium" {
let screen = UIScreen.mainScreen().bounds
customView = customAlertView.init(frame: CGRect(origin: CGPoint(x: 0,y: 80), size: CGSize(width: screen.width, height: screen.height/3)))
self.view .addSubview(customView)
}
else{
watchAllFlag = false
self.performSegueWithIdentifier("Episode", sender: self)
}
}
else {
self.showAlertPopUp()
}
}

你也可以这样做。
import UIKit
class customAlertView: UIView {
@IBOutlet weak var messageLabel: UILabel!
@IBOutlet weak var loginButton : UIButton!
@IBOutlet weak var cancelButton: UIButton!
var view : UIView!
override init(frame: CGRect) {
super.init(frame: frame)
view = setUpFromXib()
view.frame = frame
loginButton.addTarget(self, action: Selector(“loginButtonAction:”), forControlEvents: .TouchUpInside)
cancelButton.addTarget(self, action: Selector(“cancelButtonAction:”), forControlEvents: .TouchUpInside)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
func setUpFromXib() -> UIView {
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "customAlertView", bundle: bundle)
let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
addSubview(view)
translatesAutoresizingMaskIntoConstraints = true
return view
}
func loginButtonAction(sender: AnyObject) {
}
func cancelButtonAction(sender: AnyObject) {
}
}

检查它,它的工作原理:
AND id NOT IN (array_to_string(excludeArcs,','))
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
@IBAction func displayAlertBtnTapped(sender: AnyObject) {
let screen = UIScreen.mainScreen().bounds
let customView = CustomAlertView.init(frame: CGRect(origin: CGPoint(x: 0,y: 80), size: CGSize(width: screen.width, height: screen.height/3)))
self.view .addSubview(customView)
}
}
