ios - Hiding Cancel button on ABPeoplePickerNavigationController in iOS8 -

-

i attempting hide cancel button of abpeoplepickernavigationcontroller. following code works fine when run in ios 7.1 simulator, correctly hiding button. however, has no effect when run in ios 8.4 simulator. in both cases, log message written debugger, know code executing.

besides code, have tried subclassing abpeoplepickernavigationcontroller (even though apple docs not to) , setting button nil in viewdidload method, has no effect on ios 8 either.

googling this, there many posts asking how this, answers. however, none of answers appear work in ios 8. have tried solution suggested in following post (along many others) no success.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
