I can only set Accessibility Label in interface builder, but in UI Automation,I need Accessibility Identifier to get the UI elements. any way to do this?
回答1:
In Xcode 7.1 (ios 9.0) you could do it as simple as possible. Please find the image attached.
You could simply access it as view.accessibilityIdentifier
回答2:
The accessibilityIndentifier can be set in IB by using the Identity Inspector tab's 'User Defined Runtime Attributes':
Key Path: accessibilityIdentifier
Type: String
Value: Chosen accessibilityIdentifier text
E.g. setting a scroll view to have the accessibility ID 'ScrollView':
Note: This can only be used on items that have the accessibilityIdentifier property meaning they inherit from UIView. Also, typos in 'Key Path' will probably cause an exception when the item is loaded, I don't believe a compile warning/error would be given.

According to this page
http://developer.apple.com/library/ios/#documentation/AnalysisTools/Conceptual/WhatsNewInstruments/NewFeatures42/NewFeatures42.html
UIAutomation will use the accessibilityLabel if the accessibilityIdentifier is not set, so you can use that instead for now. This probably isn't best practice though because the accessibilityLabel is visible (or rather audible) to the user if they are using VoiceOver, but it's okay as long as you give the labels names that are meaningful to humans.
Hopefully Apple will add a way to set the accessibilityIdentifier in IB in future, but for now you'll have to set it in code, or use something else such as the view tag to target views for automation.

I was wondering, do you want to test things from xib that don't have IBOutlet? Can someone with more experience share his/hers thoughts?
Here is my view on the subject. If you don't assign IBOutlet to a button/label/texBox or what ever this means you won't change it from the code. The control will be static and you can see it in Interface builder. If you add an IBOutlet to a control then you can add acessibilityIdentifier from the code.
