Summary:
First of all,please forgive my poor english. LOL
When I use Promises as callBack,
I followed the guide to make a (RCTPromiseRejectBlock),in this RCTPromiseRejectBlock,
from the guide I should add a (NSString)code a (NSString)message and an (NSError) to a RCTPromiseRejectBlock.
As what did guide said I just make a NSError with
```
NSError *error=[NSError errorWithDomain:@"native stroage error" code:402 userInfo:@{@"data":key}];
```
As you can see, I want to transfer some data in this callback.But I just found the (userInfo) of NSError didn't composed to a RCTPromiseRejectBlock.
So I check out the source code of RCTUtil ,I found this
```
// TODO: Can we just replace RCTMakeError with this function instead?
NSDictionary<NSString *, id> *RCTJSErrorFromCodeMessageAndNSError(NSString *code,
NSString *message,
NSError *__nullable error)
{
NSString *errorMessage;
