objective c - iOS UITableViewController even a little scroll at top shows UIRefreshControl -

i facing weird problem tableview uitableviewcontroller. testing in ios 9.2

i have enabled "refreshing" uitableviewcontroller in storyboard , attached it's ibaction valuechanged. note tableview has section headers using "plain" style , custom height of 45.

the problem expect pull down tableview considerable amount trigger refresh control , start spinning.

however in scenario however, tiny bit of scroll makes refresh control show , start spinning. literally 2 centimeters , make appear. it's weird automatically expands in height though haven't pulled tableview enough trigger refresh.

also note though starts spinning , automatically ends spinning method linked in ibaction refresh control doesn't triggered yet.

for example scrolling , reach top, refresh control show , move tableview down, start spinning, stop spinning. without pulling tableview considerable amount.

note in code, don't have "beginrefreshing" anywhere @ all. don't have "scrollviewdidscroll" or "scrollviewdiddrag" etc methods trigger refresh control.

i have never seen sort of issue @ all.

i can't use custom viewcontroller custom tableview due other reasons, need fix this.

any appreciated!

you can add uirefreshcontrol programmatically, , work correctly. here simple example, uirefreshcontrol not iboutlet (i didn't include tableview datasource methods):

#import "viewcontroller.h"  @interface viewcontroller () <uitableviewdatasource> @property (weak, nonatomic) iboutlet uitableview *tableview; @property (strong, nonatomic) uirefreshcontrol *refreshcontrol; @end  @implementation viewcontroller  - (void)viewdidload {     [super viewdidload];      self.refreshcontrol = [[uirefreshcontrol alloc] init];     self.refreshcontrol.backgroundcolor = [uicolor lightgraycolor];     [self.refreshcontrol addtarget:self action:@selector(actionrefresh:) forcontrolevents:uicontroleventvaluechanged];     [self.tableview addsubview:self.refreshcontrol]; }  - (void)actionrefresh:(id)sender {     dispatch_after(dispatch_time(dispatch_time_now, (int64_t)(2 * nsec_per_sec)), dispatch_get_main_queue(), ^{         [self.refreshcontrol endrefreshing];     }); }  // ...uitableview datasource methods  @end
