- (void) scrollViewDidEndDecelerating : (UIScrollView *) scrollView {

  NSArray *visibleRows = [__tableView visibleCells];

  UITableViewCell *lastVisible = [visibleRows lastObject];

  NSIndexPath *path = [__tableView indexPathForCell:lastVisible];

//  NSLog(@"Section : %d // Row : %d", path.section, path.row);

  if( path.row == [__tableData count] - 1 ) {

    NSLog(@"Scroll Bottom");

  }

}

pushViewController 로 열었는 activity 닫을때 popViewControllerAnimated

열기 : [self.navigationController pushViewController:activityViewList animated:YES];

닫기 : [self.navigationController popViewControllerAnimated:YES];

NSMutableArray *requestData;

[__tableData replaceObjectsInRange:NSMakeRange(0,0)

                      withObjectsFromArray:requestData];

__tableData 데이터의 앞쪽에 새로운 데이터 추가할경우 사용

NSInteger i = [__tableView numberOfSections] - 1;

  NSInteger lastRowIndex = [__tableView numberOfRowsInSection:i] - 1;

  NSIndexPath *indexPath = [NSIndexPath indexPathForRow:lastRowIndex inSection:i];

  [__tableView scrollToRowAtIndexPath:indexPath

                     atScrollPosition:UITableViewScrollPositionBottom

                             animated:YES];

info.plist 열기

하단에 

<key>NSAppTransportSecurity</key>

  <dict>

    <key>NSAllowsArbitraryLoads</key><true/>

  </dict>

항목 추가 ( 이유 IOS9 에서 http 통신 보안 강화기능으로 인하여 차단 )

NSMutableArray *_userIds = [NSMutableArray new];

for( NSInteger i = 0; i < 3; i++ ) {

  [_userIds insertObject:@"aaaaaaaaaa" atIndex:i];

}

NSOrderedSet *userSet = [[NSOrderedSet alloc] initWithArray:_userIds];

_userIds = [[NSMutableArray alloc] initWithArray:[userSet array]];

- (UIView *) tableView : (UITableView *) tableView viewForHeaderInSection : (NSInteger) section {

  UIView *viewSection = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)];

  [viewSection setBackgroundColor:[UIColor red]];

  return viewSection;

}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

UITextField *slowFieldSpeed = [[UITextField alloc] init];

  [self.window addSubview:slowFieldSpeed];

  [slowFieldSpeed becomeFirstResponder];

  [slowFieldSpeed resignFirstResponder];

  [slowFieldSpeed removeFromSuperview];

}

넣어주면 다음부터 나오는 view의 키보드 속도가 delay 없이 올라옴
