Class Interface Builder视图的类（类型）与IBOutlet之间的关系

我只想确认我是否正确理解，在Interface Builder中，name.xib摘要窗口中Type下列出的Class Identity下设置的类是视图的类，而在IBMoutlet Class*viewName中列出的类描述了与Interface Builder的连接的性质，是否正确

e、 g

名称\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu类型

文件所有者\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

第一响应者\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu响应者

MyLabel uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuiLabel

IBUILabel*lblMyLabel

UILabel是标签的类，而IBOutlet UILabel是代码和IB对象之间的连接类型，对吗

我之所以这样问，是因为我将UIImageView子类化并更新了视图的类，但将IBOutlet声明保留为IBOutlet UIImageView，并且它仍然有效，因此我假设IBOutlet部分只是一个说明或指南。

如果您是在类的@interface部分中输入的IBOutlet关键字，如下所示：

@interface Myclass {
  IBOutlet SomeOtherClass *myObj;
}

，这将告诉Interface Builder，您将使用该类成员连接到Interface Builder中的某个其他类对象。编写此成员后，您将能够在interface builder中将此对象的连接拖动到SomeOtherClass对象，并选择myObj出口，当运行时读取.nib时，您将使对象及其之间的连接可用。

您提到的UILabel实际上是对象的类

我想了解的是，为什么我的SwipeableImage只在我将其类设置为SwipeableImageView类时才起作用，而将interface builder变量设置为IBOutlet UIImageView*mySwipeableImageView，当然interface builder连接也应该设置为IBOutlet SwipeableImage*mySwipeableImageView？没关系，原来这是IB的问题，下次我启动机器时，一切正常。
