I have an app with a button.
I start the app, then put the iPhone to sleep.
I wake the phone up and press the button repeatedly, until something happens.
There is an NSLog() in applicationWillEnterForeground: and in the action method of the button.
The time difference between these two is 1.1 ... 1.4 seconds.
Did the same with Time Profiler in Instruments: 1.357 seconds elapsed time, Running Time 0.044 sec.
That is: my app was doing nothing for about 1.3 seconds.
This is really annoying: one wakes up the phone, the app looks responsive, so one taps the button - and nothing happens.
One has to wait a second, tap the button again - and then it works.
How can I find out what is going on?
How to avoid this?
Gerriet.
iOS 7.0.4
P.S. Made a new Single View Application (which has nothing except a Done button in a Toolbar at the bottom) and did run it on iPhone 4s:
2014-01-29 21:52:55.540 TestRestart[624:60b] -[T1RAppDelegate applicationWillEnterForeground:]
2014-01-29 21:52:55.552 TestRestart[624:60b] -[T1RAppDelegate applicationDidBecomeActive:]
2014-01-29 21:52:56.949 TestRestart[624:60b] -[T1RViewController donePressed:]
2014-01-29 21:52:57.157 TestRestart[624:60b] -[T1RViewController donePressed:]
2014-01-29 21:52:57.365 TestRestart[624:60b] -[T1RViewController donePressed:]
2014-01-29 21:52:57.557 TestRestart[624:60b] -[T1RViewController donePressed:]
Again a delay of 1.397 beween applicationDidBecomeActive and the first reaction to my button.
