用 presentviewcontgroller 把 view push出来后，动画效没有程式

Question

如题，我prestioncontroller view后，我的image 直接出现在 动画结束的地方
而，这个 动画的方法 ，在其他的地方是可以作用的

是不是我应该写在某一个delete 里，或是，我写错 事件了？？

初始 的code

 let loveViewController:LoveViewController!
    loveViewController = LoveViewController();
    loveViewController.refreshWithFrame(CGRectMake(0,0,frameWidth,frameHeight))
    
    self.mainVC.presentViewController(loveViewController, animated: true, completion: nil)

viewcontroll的code

class LoveViewController: UIViewController {
var MyFunc:myFunc!
var toolBar:ToolBar!
var loveNavigationBar:UIView!
func refreshWithFrame(frame:CGRect){
    self.view = UIView(frame: UIScreen.mainScreen().bounds)
    self.view.backgroundColor = UIColor.whiteColor()
    MyFunc = myFunc()
    toolBar = ToolBar(frame: CGRectMake(0,frameHeight - frameHeight/10 ,frameWidth,frameHeight/10),page: "myheart")
    toolBar.mainVC = self
    //toolBar.page = "myheart"
    self.view.addSubview(toolBar)
    
    loveNavigationBar = UIView(frame: CGRectMake(0,0,frameWidth,frameHeight/10))
    loveNavigationBar.backgroundColor = MyFunc.colorHex("#ff69b4")
    self.view.addSubview(loveNavigationBar)
    
    let navigationBarTitleLabel:UILabel = UILabel(frame: CGRectMake(loveNavigationBar.frame.size.width / 2 - 50 , 20,100,30))
    navigationBarTitleLabel.center = loveNavigationBar.center
    navigationBarTitleLabel.textColor = UIColor.whiteColor()
    navigationBarTitleLabel.backgroundColor = UIColor.clearColor()
    navigationBarTitleLabel.text = "我的收藏"
    navigationBarTitleLabel.textAlignment = .Center
    loveNavigationBar.addSubview(navigationBarTitleLabel)
    if LoveDictionary.count == 0 {
        showNillView()
    }
}

func showNillView(){

   //以下是动画的code
    let heart:UIImageView = UIImageView(frame: CGRectMake(frameWidth / 2 - 50, frameHeight / 10 * 2, 100, 100))
    let heart_2:UIImageView = UIImageView(frame: CGRectMake(frameWidth / 2 - 50, frameHeight / 10 * 2, 100, 100))
    heart.image = UIImage(named: "bigheart")
    heart_2.image = UIImage(named: "bigheart_2")
    heart_2.alpha = 0
    self.view.addSubview(heart)
    self.view.addSubview(heart_2)
    UIView.beginAnimations("", context: nil)
    UIView.setAnimationDuration(1)
    print(111)
    heart.frame.origin.y = 300
        //heart.frame.size = CGSize(width: 100, height: 100)
    UIView.commitAnimations()
    
}

Answer 1

loveViewController.refreshWithFrame(CGRectMake(0,0,frameWidth,frameHeight))
写在LoveViewController的viewDidAppear里面最好
self.refreshWithFrame(CGRectMake(0,0,frameWidth,frameHeight))
创建controller了的时候view还没加载出来呢
