textFieldDidEndEditing firing “too late”

由 风流意气都作罢 提交于 2019-12-08 02:49:42
问题 I have a multiview process the user is entering in data and I'm saving it to the model class properties each step along the way. I use textFieldDidEndEditing to check if the input is valid, and if so, saves the entered data. On the view I have a continueButtonClicked event that checks to see if all the validations pass and if so loads the next view. I do NOT set the properties of the model here, because I think I shouldn't have to since each field is saved to the model 1 field at a time.
