iOS: 创建多个 IBOutlets 有性能开销吗？
iOS: Creating many IBOutlets has performance overhead?
如果我们从 storyboard/xib 到 ViewController/View 创建许多 IBOutlet，那么它会导致性能开销吗？如果有怎么办？
是的。这就是为什么你应该根据你的目的创建许多故事板。
例如：设置 Storyboard、Main Storyboard、User Storyboard、Picker Storyboard。
请参阅 Apple Developer 中的 IBOutlet 定义。
我们可以看到这个
the more outlets an object has, the more memory it takes up.
If there are other ways to obtain a reference to an object,
such as finding it through its index position in a matrix,
or through its inclusion as a function parameter,
or through use of a tag (an assigned numeric identifier),
you should do that instead.
所以会造成性能开销。
