iOS:覆盖子类中父类(super class)的setter属性

Question

我需要在我的子类中覆盖父类(super class)的setter

父类(super class):

公共(public)接口(interface):

 @property (weak, nonatomic) UIView *mediaView;

实现:

 - (void)setMediaView:(UIView *)mediaView
{
 // some code
}

子类:

实现:

 - (void)setMediaView:(UIView *)mediaView
{
 // some code
 _mediaView = mediaView; --- ERROR: Use of undeclared identifier '_mediaView'
 // some code 
}

我该如何解决？我需要直接设置这个属性

Answer 1

用子类中的代码解决

 @synthesize mediaView = _mediaView;
