ios - How to receive a touch ended event if a finger is already touching the screen when the app loads -


i need track if user touching screen across multiple views , separate screens throughout app. have created window delegate method receive every type of touch event. problem if keep 1 finger on first screen , tap button separate finger takes me second screen, when release original finger no event fired.

this problem same if hold finger on screen before app loads , release once it's started, no event fired touch ending.

i presume there in built system in ios states have start new touch once app has started or screen/view has changed, if release finger touching nothing happens.

is there way detect this? need keep constant accurate number of touches on screen throughout different screens/views within app, if user takes finger(s) off screen.

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
