Question

我尝试使用delegates从自定义单元格加载viewcontroller。但是我从set委托中得到nil！以下是有人可以提供帮助的示例！ 1.在Cell中

protocol hotelFindDelegate{
func modalDidFinished(modalText: String)
}
class hotelFindCell: UITableViewCell {

var delegate:hotelFindDelegate?
@IBAction func findButton(sender: AnyObject) {       

    self.delegate!.modalDidFinished("HELLO")
    print("Damn nothing works")
}

2。在主视图中

class MainViewController:hotelFindDelegate {
let modalView = hotelFindCell()
override func viewDidLoad() {
    super.viewDidLoad()
    self.modalView?.delegate = self  
}

func modalDidFinished(modalText: String){
 let viewController:UIViewController = UIStoryboard(name: "Main", bundle:          nil).instantiateViewControllerWithIdentifier("HotelListVC") as UIViewController

 self.presentViewController(viewController, animated: false, completion: nil)
 self.modalView.delegate = self
 print(modalText)  
}

Answer 1

要从XIB加载视图控制器，请执行以下步骤。

let settingVC : SettingsViewController = SettingsViewController(nibName :"SettingsViewController",bundle : nil)

稍后您可以推送相同的视图控制器对象，如

self.navigationController?.pushViewController(settingsVC, animated: true)

NSBundle.mainBundle（）。loadNibNamed（＆＃34; viewController＆＃34;，owner：self，options：nil）

如何从xib文件加载viewcontroller？
