源代码在逻辑上是矛盾的，要更改 RN 的源代码，iOS 可以如下实现，但是代价有点大。
OC 源码中是在 shouldChangeTextInRange 事件捕获 "\n" 字符串来实现 return key 的，如果_blurOnSubmit 为 true 则捕获

源码：https://github.com/facebook/react-native/blob/0e55f5b26dc60d8ce37e49b4766d7e9ec0a57605/Libraries/Text/RCTTextView.m#L349-L380

然后在 textFieldShouldEndEditing 之中，通过 _blurOnSubmit 来是判断键盘是否需要 dismiss，如果 _blurOnSubmit 为 false 则保持 keyBoard
