創建自定義IBDesignable UITextField

我想創建一個自定義UITextField並設置一個自定義bordercolor。我也爲borderColor創建了一個IBInspectable屬性，如果我使用set和get方法，我可以使用Storyboard進行設置。創建自定義IBDesignable UITextField

現在，而不是我想要做的是有一個預先定義的邊框顏色值（這是默認值），所以我想調用didSet方法，並在那裏做設置。我不知道該怎麼做。

@IBDesignable class KGIBDesignableTextField: UITextField { 

@IBInspectable var borderColor: UIColor = UIColor.KGColorPalette.entryBoxBorderColor { 
    didSet { 
     setup() 
    } 
} 


override func awakeFromNib() { 
    super.awakeFromNib() 
    setup() 
} 
override func layoutSubviews() { 
    super.layoutSubviews() 
    setup() 
} 
override func prepareForInterfaceBuilder() { 
    super.prepareForInterfaceBuilder() 
    setup() 
} 


func setup(){ 
    textColor = UIColor.KGColorPalette.textEntryFontColor 
    self.layer.borderColor=(UIColor.KGColorPalette.entryBoxBorderColor as! CGColor) 
    backgroundColor=UIColor.KGColorPalette.entryBoxShadeFillColor 
    font = UIFont(name: "Helvetica", size: 14) 
    textAlignment = .left 


}

：在故事板

error: IB Designables: Failed to update auto layout status: The agent crashed

代碼

self.layer.borderColor=(UIColor.KGColorPalette.entryBoxBorderColor as! CGColor)

錯誤 - 默認值不工作，如果我在該行的故事板導入給出了一個錯誤
}

如果它將幫助，我檢查了我的Xcode崩潰日誌以及和它給了下面的錯誤 -

改變這一行到：

self.layer.borderColor = UIColor.KGColorPalette.entryBoxBorderColor.cgColor

來自：

self.layer.borderColor=(UIColor.KGColorPalette.entryBoxBorderColor as! CGColor)

你can not typecast UIColor to CGColor。強制類型轉換會使應用程序崩潰。

謝謝你減少了編譯時錯誤。這是我身邊的一個愚蠢的錯誤。雖然我有另一個問題。當我運行的應用程序，但我沒有看到它的用戶界面，但:( –

很高興知道崩潰修復與我的答案。您可能需要發佈一個問題，關於這個新問題的更多細節。可能也添加一些截圖 – adev

感謝您的幫助，我會先嚐試自己解決問題，然後再安裝一個新的問題:) –
