IOS

UITableView has its parent class as UIScrollView. So, if you have a UITableViewCell , which has UITextField, then it needs to handle the contentOffset. More details on contentOffset  ( another url )and keyboard handling   in iOS. Lets say if we want to add a bottom inset of 216 (approx. kyeboard height). the following would be the code You basically change the content Offset while the content size remains the same. self.contentOffset = UIEdgeInset(0,0,216,0). This will move the content ( in the UITableView) up by 216. The below code also handles autosuggestion bar ,  as the autosuggestion delta (approx. 29) gets added to existing delta. And Removes it accordingly. -( void )viewWillAppear:( BOOL )animated{     [ super viewWillAppear :animated];     [ self   registerNotifications: YES ]; } -( void )viewWillDisappear:( BOOL )animated{     [ super viewWillDisappear :animated];     [ self   registerNotifications: NO ]; } -( void )registerNotifications:(

UISegmentedControl changing height is sometimes difficult to find. It can be easily done if you are using constraints. In case if you don't use constraints , I tried the following approach which I though would work, but actually it did not. - ( void )viewDidLoad {     [ super viewDidLoad ];      CGRect rect= self . seg_cntrl . frame ;     rect. size . height =60.0;     [ self . mySegmentControl setFrame :rect]; } Later on I found if you try to create a UISegmentedControl object using a code and then set the Frame it  will consider the height that you set. - ( void )viewDidLoad {     [ super viewDidLoad ];          UISegmentedControl *seg=[[ UISegmentedControl alloc ] initWithItems :@[ @"1" , @"2" ]]     ;     [seg setFrame : CGRectMake (25.0, 70.0, 300.0, 60.0)];     [ self . view addSubview :seg]; } The result can be seen in the following image.
