推荐答案

有多种方法可以实现-

1.您的代码中有一个IBOutlet引用.这是从xcode接口构建器创建的.一旦有了这个，它就很简单-

1.have an IBOutlet reference in your code. This is created from xcode Interface builder. Once you have this then it fairly straight forward -

[iboutlet_foo_object addSubview:copy3];

2. tag您感兴趣的视图.再次标记视图可以从xcode接口构建器或代码中完成.之后-

2.tag the view that you are interested in. Again tagging a view can be done from xcode Interface builder or from code. After that -

Foo *fooObj = [[self superview] viewWithTag:tagInt];
[fooObj addSubview:copy3];

3.最后，您可以遍历超级视图和所有视图中的所有视图.查看哪种类型为Foo-

3.Finally you can iterate through all the views in your superview & see which one is of type Foo -

NSArray *subviews = [[self superview] subviews];
for(UIView *v in subviews)
{
    if(v isKindOfClass:[Foo class])
    {
        [v addSubview:copy3];
        break;
    }
}
