Question

I can t seem to achieve removing a subview of a subview of a view. Its like this:

[self.view add Subview:myView]; (自己.view add Subview:myView);

[我的查看添加Subview:overlay];

我的,h:

@interface

    UIView *myView;
    IBOutlet Overlay *overlay;
...
}

@property (strong, nonatomic) UIView *myView;
@property (strong, nonatomic) IBOutlet Overlay *overlay;
...

时时:

-(void) method {   
    UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(420.0f,0.0f,604.0f,768.0f)];
    [self.view addSubview:myView]; 

    Overlay *o = [[Overlay alloc] initWithFrame:CGRectMake(000.0f,000.0f,604.0f,768.0f)];
    [myView addSubview:o];
}

I tried [myView removeFromSuperview] and[myView removeFromSuperview]inside the void method, it works. What I needed is to make it work outside or into a different void but what Im doing is not working.

注:

上面写着当我将我的 View 连接到我的 View 的本地声明隐藏实例变量时。

Answer 1

将 UIView *myView = (init code) 替换为 self.myView = (init code) 。您正在重新声明 myView 是一个本地变量, 该变量已经在您的类别中具有范围, 因为您将它设定为属性。 (同样的东西在 Overlay 中也存在。)

然后,您可以在本类的任何地方使用 [self.myView remove fromSuperview] 。
