Making a UITableView scroll when text field is selected
(45 answers)
Closed 9 years ago.
I have an application with a UITableview and a UITextView, so sometimes the keyboard is up. Whenever the keyboard is up, I can't access the bottom 3-4 table cells because they are always stuck behind the keyboard. How can I make the UITableView only take up the space above the keyboard while the keyboard is displayed?

Answer 1

I normally use https://github.com/michaeltyson/TPKeyboardAvoiding
Which will automatically solve your normal problem
But if you want to do some coding manually
Use table views setContentOffset or scrollToRowAtIndexPath
CGPoint scrollPt = CGPointMake(textFieldRect.origin.x, textFieldRect.origin.y);
[_tableView setContentOffset:scrollPt animated:YES];
UITableViewCell *cell = (UITableViewCell*) [[textField superview] superview];
[_tableView scrollToRowAtIndexPath:[_tableView indexPathForCell:cell] atScrollPosition:UITableViewScrollPositionTop animated:YES];

I've had the same problem, and here is my solution. Hope it helps.
- (void) keyboardWillShow: (NSNotification*) aNotification
{
[UIView animateWithDuration: [self keyboardAnimationDurationForNotification: aNotification] animations:^{
CGSize kbSize = [[[aNotification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
//change the frame of your talbleiview via kbsize.height
} completion:^(BOOL finished) {
}];
}
- (void) keyboardDidShow: (NSNotification*) aNotification
{
[UIView animateWithDuration: [self keyboardAnimationDurationForNotification: aNotification] animations:^{
CGSize kbSize = [[[aNotification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
//change the frame of your talbleiview via kbsize.height
} completion:^(BOOL finished) {
}];
}
- (void) keyboardWillDisappear: (NSNotification*) aNotification
{
[UIView animateWithDuration: [self keyboardAnimationDurationForNotification: aNotification] animations:^{
//restore your tableview
} completion:^(BOOL finished) {
}];
}
- (NSTimeInterval) keyboardAnimationDurationForNotification:(NSNotification*)notification
{
NSDictionary* info = [notification userInfo];
NSValue* value = [info objectForKey: UIKeyboardAnimationDurationUserInfoKey];
NSTimeInterval duration = 0;
[value getValue: &duration];
return duration;
}
Add and remove event listeners.
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver: self
selector: #selector(keyboardWillShow:)
name: UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver: self
selector: #selector(keyboardDidShow:)
name: UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver: self
selector: #selector(keyboardWillDisappear:)
name: UIKeyboardWillHideNotification object:nil];
}
- (void) dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver: self name: UIKeyboardWillShowNotification object: nil];
[[NSNotificationCenter defaultCenter] removeObserver: self name: UIKeyboardDidShowNotification object: nil];
[[NSNotificationCenter defaultCenter] removeObserver: self name: UIKeyboardWillHideNotification object: nil];
}
Methion that multi events will be received during one keyboard animation.

Try this:
CGRect frame = [tableViewer frame]; //assuming tableViewer is your tableview
frame.size.height -= 200; //200 may be a bit off, should be height of keyboard
[tableViewer setFrame:frame];
And the same thing but change -= to += for when the keyboard disappears.
