how to make catch() to then()?

[davidfuzju]

hi there, I migrate from PromiseKit to promises recently, and I have a question that is there any way to return a Promise with resolved value to make promise chain go next then(). for example:

[self fetchRemoteData]
.then(^id (id rawData) {
 // do result transformed data
    return transformedData
})
.catch(^(NSError *error) {
// get transiformed result from local catch
    return cacheDataWhichHasBeenTransiformed
})
.then(^(id transformedData) {
// dosomething
})

Hi David, thank you for trying out Promises!

It sounds like recover is what you are looking for. It allows you to catch an error, address it, and continue the promise chain.

Please let us know if you have any additional questions.
