It’s possible to build a custom interface for configuring your custom controls and have them rendered in real-time while designing your project.
Yes, we can design the custom control in interface builder with help of
IBDesignable custom views also debut in Xcode 6. When applied to a
NSView subclass, the
@IBDesignable designation lets Interface Builder know that it should render the view directly in the canvas.
IBInspectable properties provide new access to an old feature: user-defined runtime attributes. Currently accessible from the identity inspector, these attributes have been available since before Interface Builder was integrated into Xcode. They provide a powerful mechanism for configuring any key-value coded property of an instance in a NIB, XIB, or storyboard
1) Add a new visual class.
2) Add the attribute
IB_DESIGNABLE above the line beginning with
@interface SFChart : UIView
3) Include the attribute
IBInspectable with the declarations of properties that store values.
@property (nonatomic) IBInspectable NSNumber * lineWidth;
We have some limitation for IBInspectable
You can attach the
IBInspectable attribute to any property in a class declaration, class extension, or category for any type that’s supported by the Interface Builder defined runtime attributes:
- integer or floating point number
- localized string
