如何刪除不需要的按鈕陰影

Question

我的iOS應用程序已經有這兩個按鈕現在月：它們在IB，但在viewDidLoad中添加

我圓邊角和更新的背景色。

今天我添加了一個功能到一個textField是在同一個視圖。現在，當VC負載/給出的觀點似乎和，四分之一秒的延遲後，陰影出現在按鈕背後：

我沒有在屬性檢查器中改變一個單一的東西。我也沒有改變四捨五入按鈕的代碼。自問題開始以來，我現在添加了明確的無影子代碼，並確保檢查器設置爲清除陰影。

func roundBut (Type: UIView) { 
    Type.layer.cornerRadius = 6 
    Type.layer.borderWidth = 0.0 
    Type.layer.masksToBounds = true 
    Type.layer.borderColor = UIColor.whiteColor().CGColor 
    Type.layer.shadowOpacity = 0.0 
    Type.layer.shadowColor = nil 
    Type.layer.shadowRadius = 0.0 
} 

最後一個奇怪的是，如果我點擊進入文本字段，陰影就會消失。

更多的代碼，如要求：

下面是這個包括viewDidLoad中，該圓角的功能，併爲文本字段和文本視圖的代碼相關的代碼，幾乎每一個位：

override func viewDidLoad() { 
    super.viewDidLoad() 

    //If user is editing a cell, check... 
    if passingEdit == true { 
     //If passed an 'Add New' cell: It clears that text 
     if namePassed == nil && descPassed == "Add new" { 
      txtDesc.text = "" 
      addSave.setTitle("Add", forState: UIControlState.Normal) 
      action.hidden = true 
      actionsBox.hidden = true 
      passingEdit = false 
     } 
     else { 
      //Otherwise: Fill both fields with cell's content 
      txtTask.text = namePassed 
      txtDesc.text = descPassed 
      action.hidden = true //Becasue action box will be visible 
      addSave.setTitle("Update", forState: UIControlState.Normal) 
     } 
    } 
    else { 
     txtTask.becomeFirstResponder() 
     addSave.setTitle("Add", forState: UIControlState.Normal) 
     action.hidden = true 
     actionsBox.hidden = true 
    } 

    //If user hasn't added details: Show Placeholder 
    if txtDesc.text.isEmpty { 
     txtDesc.text = "Tap here to add details." 
     txtDesc.textColor = UIColor.lightGrayColor() 
    } 

    //Sets editor header text 
    switch (currentListEntity) { 
    case "TodayTask": 
     hdr_Txt.setTitle("Today", forState: UIControlState.Normal) 
     txtTask.attributedPlaceholder = NSAttributedString(string:"I need to...", attributes:[NSForegroundColorAttributeName: UIColor.lightGrayColor()]) 
     move_TopBtn.setTitle("Add to 'Tomorrow'", forState: UIControlState.Normal) 
     move_TopBtn.backgroundColor = UIColor(red: 49/255.0, green: 82/255.0, blue: 172/255.0, alpha: 1.0) 
    case "TomTask": 
     hdr_Txt.setTitle("Tomorrow", forState: UIControlState.Normal) 
     txtTask.attributedPlaceholder = NSAttributedString(string:"I need to...", attributes:[NSForegroundColorAttributeName: UIColor.lightGrayColor()]) 
     move_TopBtn.setTitle("Add to 'Today'", forState: UIControlState.Normal) 
     move_TopBtn.backgroundColor = UIColor(red: 0/255.0, green: 128/255.0, blue: 0/255.0, alpha: 1.0) 
    case "TBDTask": 
     hdr_Txt.setTitle("Do Later", forState: UIControlState.Normal) 
     txtTask.attributedPlaceholder = NSAttributedString(string:"At some point, I need to...", attributes:[NSForegroundColorAttributeName: UIColor.lightGrayColor()]) 
    case "FinTask": 
     //This won't likely run, as "Fin" does not have an add button 
     hdr_Txt.setTitle("Done", forState: UIControlState.Normal) 
    default: 
     //Should run when user's current location is the Life Lists 
     hdr_Txt.setTitle("List Item", forState: UIControlState.Normal) 
     txtTask.attributedPlaceholder = NSAttributedString(string:"Name of List Item", attributes:[NSForegroundColorAttributeName: UIColor.lightGrayColor()]) 
     move_TopBtn.setTitle("Add to 'Today'", forState: UIControlState.Normal) 
     move_TopBtn.backgroundColor = UIColor(red: 0/255.0, green: 128/255.0, blue: 0/255.0, alpha: 1.0) 
     move_BotBtn.setTitle("Add to 'Tomorrow'", forState: UIControlState.Normal) 
     move_BotBtn.backgroundColor = UIColor(red: 49/255.0, green: 82/255.0, blue: 172/255.0, alpha: 1.0) 
    } 


    //Round check/delete views 
    makeCircle(deleteBtn) 
    makeCircle(doneBtn) 
    //Round corners of rectangles 
    roundBut(move_TopBtn) 
    roundBut(move_BotBtn) 

    move_TopBtn.layer.shadowColor = UIColor.clearColor().CGColor 
    move_TopBtn.layer.shadowRadius = 0.0 

    print("editorVC viewDidLoad ran") 
}//End of viewDidLoad

最後說明：深灰色背景是視覺效果視圖。不知道這是否重要。

任何人有任何想法？

後徹底宣告我並不想在各方面我可以陰影：

//Rounded Rectangles 
func roundBut (Type: UIView) { 
    Type.layer.shadowOpacity = 0.0 
    Type.layer.shadowOffset = CGSizeMake(0, 0) 
    Type.layer.shadowColor = UIColor.clearColor().CGColor 
    Type.layer.shadowRadius = 0.0 
    Type.layer.shadowOpacity = 0.0 
    Type.layer.cornerRadius = 12.0 
    Type.layer.masksToBounds = false 
    Type.layer.borderWidth = 0.0 
} 

我終於決定要問的問題：「如果我告訴它不要，會發生什麼事的陰影正在出現我告訴它出現？「我將代碼更改爲：

//Rounded Rectangles 
func roundBut (Type: UIView) { 
    Type.layer.shadowOpacity = 1.0 
    Type.layer.shadowOffset = CGSizeMake(500, 500) 
    Type.layer.shadowColor = UIColor.clearColor().CGColor 
    Type.layer.shadowRadius = 150.0 
    Type.layer.cornerRadius = 12.0 
    Type.layer.masksToBounds = false 
    Type.layer.borderWidth = 1.0 
    Type.layer.borderColor = UIColor(red: 127/255.0, green: 127/255.0, blue: 127/255.0, alpha: 0.10).CGColor 
} 

解決，至少現在。如果它是一個固定的小故障，我將不得不留意它。

我不知道爲什麼這解決了我的問題。擺弄它，邊界是1.0或以上，而不是一個清晰的顏色是代碼，似乎使陰影消失。如果你有任何想法，請分享。
