是子类化UIWebView皱眉吗？ [英] Is subclassing UIWebView frowned upon?

问题描述

我听说过关于是否允许创建UIWebView的子类的不同的事情。 developer.apple.com/library/ios/#documentation/uikit/reference/UIWebView_Class/Reference/Reference.html#//apple_ref/doc/uid/TP40006950-CH3-DontLinkElementID_2\">将 UIWebView 引用，它说的是：

子类注释

UIWebView类不应该被子类化。

它不说为什么。我猜这是为了维护底层WebKit控件的完整性或其他东西，我dunno。

I've heard varying things about whether or not creating a Subclass of UIWebView is allowable. Can someone link me to any documentation that clarifies this one way or another?

解决方案

Under Subclassing Notes of the UIWebView reference, all it says is:

Subclassing Notes

The UIWebView class should not be subclassed.

It doesn't say why. I would guess that it's to maintain the integrity of the underlying WebKit control or something, I dunno.
