我希望通过嵌入collectionViewCell中嵌入的TableViewCell的segue传递数据；
同样来自嵌入Button的{{1}}
这是示例代码：
这是TableViewCell类：
TableViewCell's这里是class PopularCell: UITableViewCell {
@IBOutlet weak var ViewAllButton: UIButton!
@IBOutlet weak var PopularEvents: UILabel!
@IBOutlet weak var EventCollection: UICollectionView! // EMBEDDED COLLECTIONVIEW
var events = [Events]()
override func awakeFromNib() {
super.awakeFromNib()
// EMBEDDED BUTTON
ViewAllButton.setIcon(prefixText: "View All ", prefixTextColor: .blue, icon: .typIcons(.chevronRight), iconColor: .blue, postfixText: " ", forState: .normal, iconSize: 24) // EMBEDDED BUTTON
EventCollection.delegate = self
EventCollection.dataSource = self
}
extension PopularCell: UICollectionViewDelegate, UICollectionViewDataSource {
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return events.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = EventCollection.dequeueReusableCell(withReuseIdentifier: "EventCell", for: indexPath) as! EventCell
let event = events[indexPath.row]
print("Event Name:\(event.event_name)")
cell.event = event
return cell
}
}
：
ViewController(TableView Delegate & DataSource) class如何配置功能准备，以便通过“ ViewEvents” 和“ ViewEventDetails” func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return groupedEventArray.count
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 245
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "PopularCell", for: indexPath) as! PopularCell
let (category, events) = groupedEventArray[indexPath.row]
cell.ViewAllButton.addTarget(self, action: #selector(VenueViewController.ViewAll(_:)), for: .touchUpInside)
cell.PopularEvents.text = category
cell.events = events
return cell
}
@objc func ViewAll(_ sender:UIButton!) {
self.performSegue(withIdentifier: "ViewEvents", sender: sender)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if(segue.identifier == "ViewEvents") {
let destination = segue.destination as? EventListController
destination?.navigationItem.title = "Event Category"
}
else if(segue.identifier == "ViewEventDetails") {
if let collectionCell: EventCell = sender as? EventCell {
if let _: UICollectionView = collectionCell.superview as? UICollectionView {
let destination = segue.destination as? EventDetailViewController
destination?.navigationItem.title = "Event Details"
}
}
}
}
传递数据相应的标识符
