Xcode：UI 自动化：waitForValid()

Question

There's a waitForInvalid() but what about a waitForValid() function? For some reason, push/popTimeout doesn't work for me in many cases. Apple?

Answer 1

If the element is "valid" but not "visible" that might return too early. This should wait until its visible and valid.

UIATarget.localTarget().pushTimeout(20);
window.navigationBar().name()["Welcome"].withValueForKey(1, "isVisible");
UIATarget.localTarget().popTimeout();

or

UIATarget.localTarget().pushTimeout(20);
window.navigationBar().name().firstWithPredicate("name is 'Welcome' and isVisible == '1'")
UIATarget.localTarget().popTimeout();

Answer 2

When you try to access a particular element directly, there is a default wait time of 5 seconds. You can change the default time as follows.

UIATarget.localTarget().pushTimeout(20);
window.navigationBar().name()["Welcome"];
UIATarget.localTarget().popTimeout();

This will make your instruments wait up to 20 seconds until the name of the navigation bar has changed to "Welcome."
