# \[iOS] IBDesignable & IBInspectable

ex:

```swift
@IBDesignable 
class MyView: UIView {
    @IBInspectable var myColor: UIColor = UIColor.white  //注意需明确定义型态
    @IBInspectable var myTitle: String {
        get {
            return ""
        }
        set {
            
        }
    }
}  
```

缺點: 無法使用code一次批次修改大量參數
