Here I have a tableView on a scrollView. Each row contains a textField. Next button is ok(view animating properly on upword) but when I press on previous button on keyboard, I have to show down the view one by one according to the textField. How can I solve this? I have to do it in many views. Please help me as soon as possible. I badly need it. May be I'm doing wrong somewhere. Sorry for my language problem. Sample code may be helpful.
Hi Please try the below method to scroll your tableview up and down based on which text field is selected, write this code in textfield delegate method
- (void)textFieldDidEndEditing:(UITextField *)textField{
// calculate the nsindexpath based on the textfield which is selected
//- (void)scrollToRowAtIndexPath:(NSIndexPath *)indexPath atScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated;
[yourtableview scrollToRowAtIndexPath:calcutaedIndexPath atScrollPosition:UIScrollViewPositionTop animated:YES];
}
Hope it will help you

I have textfield in every row of tableview. click on textfield
-(void)textFieldDidBeginEditing:(UITextField *)textField
method called but keyboard not appear. I have written
[tableView reloadData];
in the method.
Keyboard appear if I remove [tableView reloadData]; this
any solution ?
Have you check the property KEYBOARD ? By selecting tableview and in attribute inspector set Keyboard property to do not dismiss and try
press cmd+K from keyboard if you are using simulator.
I want to set a recent search history dropdown for UISearchbar . I have implemented a dropdown programatically using a UITableView
Logic:
How i have implemented is by setting a UITableView right below the UISearchBar and on click on the UISearchBar it will pop up .
Am initially hiding that tableview in viewdidload and in
-(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar am unhiding the tableview .
Iam facing too many problems with this :
1. The return button is not enabled when the searchbartext is empty .In that case if i have to cancel/hide the table view again i have to depend on tapgestures .
2. Clicking on the searchbartext again won't trigger any of its delegates. The only time it triggers the delegates on click on the searchbartext is when click on it for the first time then it calls -(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
Do u guys have any other solution / way to implement this feature in a much better way than this ??
Do we have any custom made UISearchBar recent history dropdowns ??
I have searched for a custom UISearchBar recent history dropdown in cocoacontrols,code4app and cocoapods for this no hope dint find any .
Please help me with this .
For your first issue, you can add a category on UISearchBar something like this and this shall always enable your return button on keyboard when tapped on UISearchBar
#implementation UISearchBar (MyAddition)
- (void)alwaysEnableSearch {
// Loop around subviews of UISearchBar
NSMutableSet *viewsToCheck = [NSMutableSet setWithArray:[self subviews]];
while ([viewsToCheck count] > 0) {
UIView *searchBarSubview = [viewsToCheck anyObject];
[viewsToCheck addObjectsFromArray:searchBarSubview.subviews];
[viewsToCheck removeObject:searchBarSubview];
if ([searchBarSubview conformsToProtocol:#protocol(UITextInputTraits)]) {
#try {
// Force return key to be enabled
[(UITextField *)searchBarSubview setEnablesReturnKeyAutomatically:NO];
}
#catch (NSException *iException) {
}
}
}
}
For second issue, why don't you use shouldChangeTextInRange: delegate method which gets called for each entered character.
As a side note, this SO thread has a sample code to do this. This may help you.
Good luck!
I am re-writing the possible steps as per your recent clarification.
keep a flag/boolean to monitor tableview is hidden or not.
in the UISearchBar Delegate method check the serachbar's text field's [obj isFirstResponder] method.
a. if firstResponder =yes --> Show the histroy tableview OR Vice versa.After show/hide is accomplished call below method on UISearchBar' textfield.
*[searchbarobj.textfield resignFirstResponder];*
b. if firstResponder = No---> Don't do anything. leave the method.
I have a UITableViewController with custom cells that have text fields in them. I want the table view to scroll whenever the user enters a text field, so I do this:
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
// ... irrelevant code here ...
[self.tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
// ... more irrelevant code here ...
}
This method normally works great, but when quicktype keyboard appears the quicktype bar partially overlaps the cell.
How do I fix that overlapping issue?
Here is the UI:
I have a table view that has rows including text fields. For example row1 has textField1 and row2 has textField2.
Now, if the user taps the textField1, everything works fine. The delegate is called and everything.
If the user, then, taps the textField2, only the textFieldDidEndEditing: is called for textField1. textFieldDidBeginEditing: is not called for textField2 (I am pretty sure that textField2 delegate is set, because when I then tap textField2 (again), it starts editing (textFieldDidBeginEditing: is now called)
You may think this is not a real problem. The problem is that the iOS keeps showing the keyboard! With no text fields associated to it! I even loop to all text fields in all visible rows and resign them with no luck.
Seems a bug in iOS, right?
Edit: Here is the code in the delegate
- (void) textFieldDidBeginEditing:(UITextField *)textField {
[self fixTableViewOffsets];
RSMCellEditPricesCell *cell = (RSMCellEditPricesCell *) [[textField superview] superview];
[self.tableView scrollToRowAtIndexPath:[self.tableView indexPathForCell:cell]
atScrollPosition:UITableViewScrollPositionTop
animated:YES];
}
- (void) textFieldDidEndEditing:(UITextField *)textField {
self.currentPriceTextField = nil;
[self fixTableViewOffsets];
[self.tableView reloadData];
}
First of all, be careful with the naming conventions, if you are adding a label at the end of a variable that variable should be a UILabel not a UITextField. Second your problem might be in the textFieldDidEndEditing method, you are calling resignFirstResponder on all your text fields(if the cell.priceLabel is a text field). You shouldn't callresignFirstResponder in textFieldDidEndEditing or textFieldSouldReturn because if those methods are called the text fields are already resign as first responder.
I couldn't find a fix for it. However, as a workaround, I disabled the second text field. When the user taps this field, it will trigger the touch event on cell, not the text field which will dismiss the keyboard. Then, I enable all text fields and the user can select this second text field again.
It's not quite a solution and it doesn't provide the best UX. Still, it work.
I have a modal set up like this:
Despite appearances, the first two fields are UITextFields that become first responders and display the keyboard. The third 'Department' item is a table view and pushes another view.
I have implemented a scroll view so that while either of the fields is being edited, the user can scroll around and reach the department cell:
When it is selected, before the push, I would like to hide the keyboard. It's a small detail, but try adding a new event on Apple's 'Calendar' app. It opens with the first text field as first responder (so keyboard is present). If you select the start/end cell, the keyboard hides as the next view is pushed.
How do I achieve this? As a test I tried:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"hiding keyboard");
if ([ingredientName isFirstResponder]) {
NSLog(#"resigning name field");
[ingredientName resignFirstResponder];
}
else if ([ingredientAmount isFirstResponder]){
NSLog(#"resigning amount field");
[ingredientAmount resignFirstResponder];
}
}
The logging confirms that these are getting called. But the keyboard does not hide. It simply stays in place as the view slides out. And on return, the previous field still has focus (and the keyboard is out).
Any ideas?
resignFrstResponder will not dismiss the keyboard when you're using a modal view.
Another dev found a workaround for this behavior here: http://viraj-workstuff.blogspot.com/2010/12/resignfirstresponder-does-not-hide.html
Not terribly elegant, but try stealing the firstresponder status with an ad-hoc, invisible UITextField:
-(void)dismissKeyboard {
UITextField *textField;
textField=[[UITextField alloc] initWithFrame:CGRectZero];
[self.view addSubview:textField];
[textField becomeFirstResponder];
[textField resignFirstResponder];
[textField removeFromSuperview];
// [textField release] // uncomment if not using ARC
}
Two things:
Are you using a segue for pushing that other VC? If so, resign the keyboard in the prepareForSegue method.
If not, try using willSelectRowForIndexPath instead of didSelectRowAtIndexPath
