[英]Custom view outlets in iOS swift are not working in view controller
大家好,我已經快速使用了一個視圖控制器和一個自定義視圖
視圖控制器
import UIKit
class ViewController: UIViewController {
var genderView : GenderOptionView!
override func viewDidLoad() {
super.viewDidLoad()
loadGenderCustomView()
}
func loadGenderCustomView() {
genderView = GenderOptionView(frame: CGRectMake(0,0,rectIs.size.width * 0.95, rectIs.size.height * 0.355)) { (ScreeenType) -> () in
if(ScreeenType == 0)
{
print("Show Gender");
//self.ShowLoginScreen()
}
};
self.view.addSubview(genderView)
}
}
自訂檢視
import UIKit
class GenderOptionView: BaseView {
//static let sharedGenderOptionViewInstance = GenderOptionView()
@IBOutlet weak var maleImgView: UIImageView!
@IBOutlet weak var maleBtn: UIButton!
@IBOutlet weak var maleLbl: UILabel!
internal init(frame: CGRect, OnActions:(ScreeenType:NSInteger) -> ()){
super.init(frame: frame)
let myView = NSBundle.mainBundle().loadNibNamed("GenderOptionView", owner: self, options: nil)[0] as! UIView
self.frame = CGRectMake(frame.origin.x + 6,315,self.bounds.width,myView.bounds.height)
myView.frame = frame
//myView.backgroundColor = UIColor.greenColor()
//self.backgroundColor = UIColor.yellowColor()
OnActionsRef = OnActions;
self.addSubview(myView)
self.maleBtn.alpha = 0.0// I am getting here.. bad excess and in console fatal error: unexpectedly found nil while unwrapping an Optional value
}
}
我在最后一行收到錯誤..嚴重超額和控制台致命錯誤:在視圖控制器中加載該視圖后,在展開Optional值時意外發現nil
基本視圖是
import UIKit
class BaseView: UIView {
var OnActionsRef : (ScreeenType:NSInteger) -> () = {_ in };
}
采用
myview.maleBtn.alpha = 0.0
因為您沒有在自己中加載筆尖,所以您正在myview中加載
