We define weex module method like this on iOS platform:
- (void)someFunction:(NSDictionary *)options {
// parse options dictionary
}
Parameter options is treated as NSDictionary *, expecting any javascript object
is converted to a NSDictionary * instance. undefined/null should convert to
nil, but not a NSString *.
It is reasonable to check the parameter types, but not for this weird rule. And
if parameter of a method is string, we can never distinguish between empty
string and undefined.

The undefined type in the client does not have an explicit corresponding
type, it will resulting from the `Object` to `String`, this problem will
cause the iOS application to crash.
