xcode - 具有多个标识符的 prepareForSegue
xcode - prepareForSegue with multiple identifiers
我有一个包含两个部分的 tableView(不是静态单元格)
一个酒吧部分和一个俱乐部部分(每个部分都有几个单元格)。我希望同一部分的每个单元格都指向相同的 viewcontroller。
我只能访问第一个,不能访问最后一个。即使是第二部分的 de cells 也转到第一部分 viewcontroller.
有人能看出我的错误吗?
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 2
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
if section == 0 {
return areas.bars.count
} else {
return areas.clubs.count
}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("mainIdentifier", forIndexPath: indexPath)
if indexPath.section == 0 {
let bars = areas.bars
let bar = bars[indexPath.row]
cell.textLabel?.text = bar.name
return cell
} else {
let clubs = areas.clubs
let club = clubs[indexPath.row]
cell.textLabel?.text = club.name
return cell
}
}
继续:
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "barsandclubsIdentifier"{
let selectedIndex = self.tableView.indexPathForSelectedRow!
let selectedBar = self.areas.bars[selectedIndex.row]
let detailBarsAndClubsViewController = segue.destinationViewController as! DetailBarOrClubViewController
detailBarsAndClubsViewController.bars = selectedBar
}
else {
let selectedIndex = self.tableView.indexPathForSelectedRow!
let selectedClub = self.areas.clubs[selectedIndex.row]
let detailBarsAndClubsTwoViewController = segue.destinationViewController as! DetailBarOrClubTwoViewController
detailBarsAndClubsTwoViewController.clubs = selectedClub
}
每个原型单元格只能转到一个 viewController。如果您有 2 个不同的目的地 viewController,则需要 2 个原型单元格:1 个用于酒吧,1 个用于俱乐部。给他们每个人一个唯一的标识符,例如 "barCell"
和 "clubCell"
.
然后在 cellForRowAtIndexPath
中,使适当的单元格出队:
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellID = ["barCell", "clubCell"][indexPath.section]
let cell = tableView.dequeueReusableCellWithIdentifier(cellID, forIndexPath: indexPath)
然后您可以将每个原型单元连接到适当的 viewController。给这两个 segue 中的每一个一个唯一的标识符,例如 "barSegue"
和 "clubSegue"
,然后您可以使用 prepareForSegue
中的那些来配置目标 viewController.
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "barSegue"{
let selectedIndex = self.tableView.indexPathForSelectedRow!
let selectedBar = self.areas.bars[selectedIndex.row]
let detailBarViewController = segue.destinationViewController as! DetailBarViewController
detailBarsViewController.bars = selectedBar
}
else if segue.identifier = "clubSegue" {
let selectedIndex = self.tableView.indexPathForSelectedRow!
let selectedClub = self.areas.clubs[selectedIndex.row]
let detailClubViewController = segue.destinationViewController as! DetailClubViewController
detailClubsViewController.clubs = selectedClub
}
}
