It turns out the delay is NOT really the problem - there is a similar delay on iOS 6 which has never bothered me. The real problem is: iOS 7 ignores the first tap (if it comes too soon after applicationDidBecomeActive: - "too soon" meaning: less than about a second). Whereas iOS 6 records and processes all taps. Thanks to Rick Mann for helping me with this.
