我有一个UITableView,其中包含使用UIButton自定义操作创建的交互式节标题。按下此按钮时,将通过prepareForSegue对另一个View Controller执行segued。但是,此功能中不提供节选择。是否有解决方案可以提供部分索引?由于section已在viewForHeaderInSection中可用,是否可以将其传递给prepareForSegue?
还有另一个thread具有相似的主题,但我无法确定部分索引。
提前致谢, 杰拉德
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
let header = UIView()
let btn = UIButton(type: UIButtonType.Custom) as UIButton
btn.frame = CGRectMake(0, 0, tableView.frame.size.width, 40)
btn.addTarget(self, action: "buttonAction:", forControlEvents: .TouchUpInside)
btn.setTitle(String(section), forState: .Normal)
btn.setTitleColor(UIColor.blackColor(), forState: .Normal)
header.addSubview(btn)
return header
}
func buttonAction(sender:UIButton!)
{
self.performSegueWithIdentifier("myIdentifier", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "myIdentifier" {
let detailViewController = segue.destinationViewController as! MyViewController
if let selectedSection = sender {
// Here the selected section should be determined....
// ... so that data can be passed to detailViewController, e.g.
// detailViewController.sectionNumber = section
}
}
答案 0 :(得分:0)
这是你可以做的添加变量var sectionToPass:Int
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
let header = UIView()
let btn = UIButton(type: UIButtonType.Custom) as UIButton
btn.frame = CGRectMake(0, 0, tableView.frame.size.width, 40)
btn.addTarget(self, action: "buttonAction:", forControlEvents: .TouchUpInside)
//Add This Part
btn.tag = section
//
btn.setTitle(String(section), forState: .Normal)
btn.setTitleColor(UIColor.blackColor(), forState: .Normal)
header.addSubview(btn)
return header
}
func buttonAction(sender:UIButton!)
{
//ADD THIS PART
sectionToPass = sender.tag
//
self.performSegueWithIdentifier("myIdentifier", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "myIdentifier" {
let detailViewController = segue.destinationViewController as! MyViewController
if let selectedSection = sender {
// Here the selected section should be determined....
// ... so that data can be passed to detailViewController, e.g.
// detailViewController.sectionNumber = section
//ADD THIS PART
detailViewController.sectionNumber = sectionToPass
}
}
