Incomplete universal character name in UI Testing

问题:

I am using Xcode 7's new feature : UI Testing. After recording the interaction, Xcode generated the code automatically :

- (void)testDoubleTapToolBarItem {
    [[[XCUIApplication alloc] init].tabBars.buttons[@"\U5173\U6ce8"] doubleTap];
                                                    ~~~~~~~~~~~~~~~~
}

However, warning showed as well. Any one know how to fix this?

Edit: This seems to be a BUG since Xcode 7.0 GM

回答1:

You can use the following workaround as this seems to be a bug in xcode:

replace all \U to \u and it should work.

回答2:

I tried replace \U to \u but still got error "Expected hexadecimal code in braces after unicode escape", so have to add \u{you value here}, like collectionViewsQuery.buttons["\u{6ce8}\u{518c}"].tap()
