objective c - UIRefreshControl offset changes after loading new items to UITableView -

-

i added uirefreshcontrol uitableview.

the uitableview under top bar.

everything works fine except when new items being loaded. example, if table had 1 row , now, after reloading data there 2 rows.

after table being reloading, uirefreshcontrol offset isn't in 0 position of uitable adding bar height user needs pull not height of uirefreshcontrol height of top bar.

after loading again same data, uirefreshcontrol ok.

- (void)viewdidload {     [super viewdidload];      [self setrefreshcontrol];  } -(void)setrefreshcontrol {     refreshcontrol = [[uirefreshcontrol alloc]init];     refreshcontrol.tintcolor=[uicolor redcolor];     [self.campaignstableview addsubview:refreshcontrol];     [refreshcontrol addtarget:self action:@selector(refreshtable) forcontrolevents:uicontroleventvaluechanged];  }

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
