Question

我在IOS 8中解决了我的问题，但我的代码在IOS 9中运行。我创建了一个透明按钮，并在Tabbar方法中添加子视图。问题是第二次tabar加载时按钮事件不起作用，这在IOS 8中是个问题，但它在ISO 9中运行良好。这是我的代码

委派

var button_ofTabbar = UIButton();
     //var button_ofTabbar:UIButton!;

    //UIButton();= UIButton(type: UIButtonType.System)

在标签栏中

class tabbar: UITabBarController,UITabBarControllerDelegate {




    //let button_ofTabbar   = UIButton();

    var delegate1: AppDelegate!
     let aDataBase : databaseinit = databaseinit()

    override func viewDidLoad() {
        super.viewDidLoad()



        UITabBar.appearance().tintColor = UIColor(red: 242/255.0, green: 134/255.0, blue: 55/255.0, alpha: 1.0)
        self.delegate=self;
         delegate1 = UIApplication.sharedApplication().delegate as! AppDelegate



        UITabBar.appearance().barTintColor = UIColor.whiteColor()


        if(delegate1.tag_jive_channel_tab == 0)
        {
           //  delegate1.button_ofTabbar.removeFromSuperview();
           // delegate1.button_ofTabbar.setTitleColor(UIColor.blackColor(), forState: UIControlState.Normal)


            delegate1.button_ofTabbar.hidden = false;
            let widthofbtn:CGFloat = self.tabBar.frame.size.width/5;

        delegate1.button_ofTabbar.frame = CGRectMake(0, self.tabBar.frame.origin.y, widthofbtn, self.tabBar.frame.size.height)
            delegate1.button_ofTabbar.backgroundColor = UIColor.redColor()//clearColor()

           //delegate1.button_ofTabbar = UIButton(type: UIButtonType.System)
        delegate1.button_ofTabbar.tintColor = UIColor.redColor()//clearColor()
        delegate1.button_ofTabbar.addTarget(self, action: "gotoShowChannel11", forControlEvents: UIControlEvents.TouchUpInside)

        self.view.addSubview(delegate1.button_ofTabbar);


        }

    }
    override func viewDidAppear(animated: Bool) {

       }
func gotoShowChannel11() {

        delegate1.button_ofTabbar.hidden = true;
        //orangeColor tabbar
        //self.tabBarController?.tabBar.tintColor = UIColor.redColor();
        delegate1.tag_jive_channel_tab = 1;

        NSNotificationCenter.defaultCenter().postNotificationName("update_tabbar", object: nil,
            userInfo: nil);

            //UIColor(red: 146/255.0, green: 146/255.0, blue: 146/255.0, alpha: 1.0)
    }

当我使用此行delegate1.button_ofTabbar = UIButton(type: UIButtonType.System)时，我的按钮不会显示自定义/系统

我也试试这个func gotoShowChannel11(sender: UIButton!) 请帮我。我陷入了IOS 8问题。和错误是 错误 - [__NSCFData gotoShowChannel11] 请任何人帮助我。现在我找到了另一个解决方案。谢谢你。

Swift ERROR- [__ NSCFData gotoShowChannel11]当我在Delegate中创建按钮并在tabbar上添加视图时
