我想知道用户点击了哪个 imageview 我正在使用以下代码，但它没有调用 leftTapView 和 rightTapView 函数
class CustomTableViewCell : UITableViewCell {
@IBOutlet var leftTeamImage: UIImageView!
@IBOutlet var rightTeamImage: UIImageView!
@IBOutlet var rightTeamNameLabel: UILabel!
@IBOutlet var leftTeamNameLabel: UILabel!
@IBOutlet var leftTeamScoreLabel: UILabel!
@IBOutlet var rightTeamScoreLabel: UILabel!
@IBOutlet var leftView : UIView!
@IBOutlet var rightView : UIView!
let lettTapRec = UITapGestureRecognizer()
let rightTapRec = UITapGestureRecognizer()
ScoreLabel.text = leftTeamScore
rightTeamNameLabel.text = rightTeamName.uppercaseString
rightTeamScoreLabel.text = rightTeamScore
}
func load(#leftTeamName: String, rightTeamName: String, leftTeamScore: Int, rightTeamScore: Int) {
leftTeamNameLabel.text = leftTeamName.uppercaseString
leftTeamScoreLabel.text = String(leftTeamScore)
rightTeamNameLabel.text = rightTeamName.uppercaseString
rightTeamScoreLabel.text = String(rightTeamScore)
lettTapRec.addTarget(self, action: "leftTapView")
leftView.userInteractionEnabled = true
leftView.addGestureRecognizer(lettTapRec)
//
rightTapRec.addTarget(self, action: "rightTapView")
rightView.userInteractionEnabled = true
rightView.addGestureRecognizer(rightTapRec)
}
func leftTapView(sender: AnyObject){
println("left")
}
func rightTapView(sender: AnyObject){
println("left")
}
}
protocol ImageTappedProtocols {
func leftImageTapped(imageView : UIImage)
func rightImageTapped(imageView: UIImage)
}
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
@IBOutlet var tableView : UITableView!
var items: [(String, String)] = [
("My", "swift 1.jpeg"),
("Name", "swift 2.jpeg"),
("is", "swift 3.jpeg"),
("Atif", "swift 4.jpeg"),
("Farrukh", "swift 5.jpeg")
]
var team1 :[String] = []
var team2 :[String] = []
var id : [String] = []
var team1_bets : [Int] = []
var team2_bets : [Int] = []
var end_date : [String] = []
var list = Dictionary<String, String>()
var count : Int = 0
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return count;
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:CustomTableViewCell = self.tableView.dequeueReusableCellWithIdentifier("customCell") as CustomTableViewCell
// this is how you extract values from a tuple
var (title, image) = items[indexPath.row]
var teama: String = team1[indexPath.row]
var teamb: String = team2[indexPath.row]
var teamAScore : Int = team1_bets[indexPath.row]
var teamBScore : Int = team2_bets[indexPath.row]
cell.backgroundColor = UIColor(red: 123, green: 225, blue: 38, alpha: 0.2)
return cell
}
func tableView(tableView : UITableView, didSelectedRowAtIndexPath indexPath : NSIndexPath){
//tableView.deselectRowAtIndexPath(indexPath, animated: true)
println("You selected cell #\(indexPath.row)!")
let indexPath = tableView.indexPathForSelectedRow();
let currentCell = tableView.cellForRowAtIndexPath(indexPath!) as UITableViewCell!;
println(currentCell.textLabel.text)
}
func tableView(tableView : UITableView, didSelectRowAtIndexPath indexPath : NSIndexPath){
//tableView.deselectRowAtIndexPath(indexPath, animated: true)
println("You selected cell #\(indexPath.row)!")
let indexPath = tableView.indexPathForSelectedRow();
let currentCell = tableView.cellForRowAtIndexPath(indexPath!) as UITableViewCell!
println(currentCell.contentView)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let urlAsString = "http://codespikestudios.com/betting_app/bet/get_events/1"
//let urlAsString = "http://api.topcoder.com/v2/challenges?pageSize=2"
let url: NSURL = NSURL(string: urlAsString)!
let urlSession = NSURLSession.sharedSession()
//2
let jsonQuery = urlSession.dataTaskWithURL(url, completionHandler: { data, response, error -> Void in
if (error != nil) {
println(error.localizedDescription)
}
var err: NSError?
// 3
var jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &err) as NSArray
if (err != nil) {
println("JSON Error \(err!.localizedDescription)")
}
// 4
println(jsonResult)
println(jsonResult.count)
println(jsonResult[1].valueForKey("cat_name") as String)
var dictionary = Dictionary<String, String>()
self.count = jsonResult.count
for var i = 0; i < self.count; i++ {
self.team1 = jsonResult.valueForKey("team1") as Array
self.team2 = jsonResult.valueForKey("team2") as Array
self.team1_bets = jsonResult.valueForKey("team1_bets") as Array
self.team2_bets = jsonResult.valueForKey("team2_bets") as Array
}
dispatch_async(dispatch_get_main_queue(), { () -> Void in
self.tableView.reloadData()
})
//let jsonDate: String! = jsonResult["date"] as NSString
//let jsonTime: String! = jsonResult["time"] as NSString
//println(jsonTime)
})
// 5
jsonQuery.resume()
var nib = UINib(nibName: "MyTableViewCell", bundle: nil)
tableView.registerNib(nib, forCellReuseIdentifier: "customCell")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
这就是我得到的
You selected cell #3!
<UITableViewCellContentView: 0x7f871b687350; frame = (0 0; 580 136.5); opaque = NO; gestureRecognizers = <NSArray: 0x7f871b68c180>; layer = <CALayer: 0x7f871b687420>>
最佳答案
当你初始化你的手势识别器时，你会想要添加一个目标。这看起来像，例如:
let leftTapRect = UIGestureRecognizer(target: self, action: "leftTapView:")
此外，您需要向事件处理程序 leftTapView 和 rightTapView 添加一个 sender 参数:
func leftTapView(sender: AnyObject) {
...
}
