how to set default view property's order?

[fov42550564]

when I create a custom view, it has several properties, how can I make sure these properties' order.

RCT_CUSTOM_VIEW_PROPERTY(props1, NSInteger, MyView) {
   doSomeThing1();
}
RCT_CUSTOM_VIEW_PROPERTY(props2, NSInteger, MyView) {
   doSomeThing2();
}

doSomeThing2 depend on doSomeThing1, so when I set default property I want doSomeThing1 exec before doSomeThing2, as follows:

<MyView props1={1} props2={2} />

Is there has some ways to solve it?

Hey @fov42550564 and thanks for posting this! @charpeni tells me this issue looks like a question that would be best asked on StackOverflow. StackOverflow is amazing for Q&A: it has a reputation system, voting, the ability to mark a question as answered.

I'm also facing this issue. Since the props on iOS side are stored in an NSDictionary, the keys are unordered. This means props have no guaranteed order in which they're updated.

Honestly, this behavior seems weird to me.
I assumed the props would be updated based on their order in the JS object.
At the very least, this should be documented better.

@ide Do you know a way around this?

Looks like the best solution is to implement didSetProps in your view implementation.

- (void)didSetProps:(NSArray<NSString *> *)changedProps
{
  // Do something that depends on all props having a value.
}
