react-redux-v6: withRef is removed. To access the wrapped instance, use a ref on the connected component
提问by 2 8
I want to call a function from a connected component using ref, so I used before from withRef: truein connected component:
我想使用从连接组件调用一个函数ref，所以我之前withRef: true在连接组件中使用过：
export default connect(
mapStateToProps, mapDispatchToProps, null, {withRef: true}
)(InviteReceiverForm)
and in the presentational component:
并在展示组件中：
<ExampleComponent
ref={ cmp => { if(cmp) { this.individualSenderFormRef = cmp.getWrappedInstance() }} />
But after I updated to react-redux v6, I got this error:
但是在我更新到之后react-redux v6，我收到了这个错误：
withRef is removed. To access the wrapped instance, use a ref on the connected component

The
withRefoption to connect has been replaced withforwardRef. If{forwardRef : true}has been passed toconnect, adding a ref to the connected wrapper component will actually return the instance of the wrapped component.
该
withRef选项连接已被替换forwardRef。如果{forwardRef : true}已传递给connect，则向连接的包装组件添加 ref 将实际返回包装组件的实例。

It's work for me:
这对我有用：
connect(
mapStateToProps,
null,
null,
{
forwardRef: true
}
)
)(ComponentName);
