I have a textfield that runs a calculation and updates a label when Editing

  • 0

I have a textfield that runs a calculation and updates a label when Editing Changed. The textfield is formated for currency using textField: shouldChangeCharactersInRange:

The label is also formatted for currency.

In IOS 5 the label would update as the number was typed into the textfield.

In IOS 6 the label won’t update until a value is entered in a different textfield.

Has anything changed in IOS 6 or Xcode 4.5 to make Editing Changed or textField: shouldChangeCharactersInRange: work differently?

    Yes I justs noticed the same thing – make note that only if shouldChangeCharactersInRange returns “NO” will editingChanged not get called – even so I suspect that this is a bug and should be reported to Apple. The EditingChanged event is just an event in which UITexField inherits from UIControl and I don’t see why Apple should stop it from working even if shouldChangeCharactersInRange returns “NO” the textfield should know if there was a change made.

    What I am doing is moving my code from the editingChanged event directly into the shouldChangeCharactersInRange method. Meaning, that where I return “NO” I am embedding the code I would have wanted to call in the editingChanged event. Should work for most cases. Hope this helps.
