ios - How to make UITableview exact height and removing unwanted white space footer? -

i have following issue having 1 button on main view if click on button add subview on main view tableview here code

viewcontroller *settings = [[viewcontroller alloc]initwithnibname:@"viewcontroller" bundle:nil]; settings.delegate=self; [settings.view setframe:cgrectmake(0, 30, self.view.frame.size.width,250)]; [self.view addsubview:settings.view]; 

after click on button subview tableview rest of them having whitespace.

then how remove remaining whitespace.

at first sight, looks have set wrong height of viewcontroller's view i.e., 250. make sure tableview inside view have same height assigning in setframe function here:

viewcontroller *settings = [[viewcontroller alloc]initwithnibname:@"viewcontroller" bundle:nil]; settings.delegate=self; [settings.view setframe:cgrectmake(0, 30, self.view.frame.size.width, heightofyourtableview)]; [self.view addsubview:settings.view]; 

hope helps!
