I have a custom cell and in the custom cell, I have a textfield where user can able to change the value. No matter, what I tried, I cannot able to dismiss the keyboard when user enters some values. It does not hit any of the delegate methods shown below.
CheckOutTableViewCell.m
#import "CheckOutTableViewCell.h"
#implementation CheckOutTableViewCell
#synthesize productName;
#synthesize productPrice;
#synthesize productOrderNumberTF;
- (void)awakeFromNib {
[super awakeFromNib];
// Initialization code
}
-(id) init;
{
self = [super init];
if (!self) return nil;
productOrderNumberTF.delegate = (id)self;
return self;
}
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
// enter closes the keyboard
if ([string isEqualToString:#"\n"])
{
[textField resignFirstResponder];
return NO;
}
return YES;
}
- (void) textFieldDidEndEditing:(UITextField *)textField {
NSLog(#"%#", textField.text);
}
- (BOOL)textFieldShouldEndEditing:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
// dismiss keyboard when user clicks on anywhere on the UI
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self.productOrderNumberTF resignFirstResponder];
}
CheckOutTableViewController.m
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"cell";
CheckOutTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil)
{
cell = [[CheckOutTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
cell.productOrderNumberTF.delegate = (id)self;
}
return cell
}
Screenshot of the ViewController
Your delegate methods are not calling because of your textfield delegate value is not assigned.
Assign the delegate value inside the awakeFromNib
- (void)awakeFromNib {
[super awakeFromNib];
productOrderNumberTF.delegate = self;
}
The nib-loading infrastructure sends an awakeFromNib message to each object recreated from a nib archive, but only after all the objects in the archive have been loaded and initialized. When an object receives an awakeFromNib message, it is guaranteed to have all its outlet and action connections already established.

I have a simple custom table view cell that has a label and a textfield. Looks like this in the storyboard:
I would like to show the keyboard when the user clicks anywhere in the cell, including if they click the label. I was 99% sure the way to achieve this would be to call becomeFirstResponder when the cell is clicked.
Here is my simple ViewController:
#import "ViewController.h"
#interface ViewController ()
#property (weak, nonatomic) IBOutlet UITableView *tableView;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.tableView.dataSource = self;
self.tableView.delegate = self;
[self.tableView setEstimatedRowHeight:44.0f];
[self.tableView setRowHeight:UITableViewAutomaticDimension];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 1;
}
- (NSInteger) numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"custom"];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [self tableView:tableView cellForRowAtIndexPath:indexPath];
BOOL firstResponder = [cell becomeFirstResponder];
}
And my custom table view cell:
#import "CustomTableViewCell.h"
#implementation CustomTableViewCell
- (void)awakeFromNib {
[super awakeFromNib];
// Initialization code
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
- (BOOL) canBecomeFirstResponder {
return YES;
}
- (BOOL) becomeFirstResponder {
return [self.textField becomeFirstResponder];
}
#end
I verified that becomeFirstResponder is called, however that is returning false. What am I missing?
Think as #alex-i points out in a comment here:
This [text field not becoming first responder] can also occur when the textfield is briefly removed from the
view/window hierarchy while becoming the first responder (e.g.
reloading a UITableView or UICollectionView that holds that
textfield).
Which will happen on selection.
Rather than use didSelectRowAtIndexPath, you can add a UITapGestureRecognizer to your tableView with an action like:
- (IBAction)tap:(UITapGestureRecognizer *)sender
{
CGPoint location = [sender locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:location];
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
BOOL firstResponder = [cell becomeFirstResponder];
}
And it will become first responder.
If someone needs a swift alternative: You can connect outer UIViews with outlet collection. On each UIViewController class you have once call below. So that when the outer box is touched, editfield will be activated with keyboard. You can apply this to your labels as well. (By disabling label's User Interaction)
#IBOutlet var outerBoxes:[UIView]!
override func viewDidLoad() {
super.viewDidLoad();
for outerBox in outerBoxes { outerBox.respondForEditBox() };
...
But once you have to have this code:
extension UIView {
func respondForEditBox() {
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIView.focusOnEditBox));
self.addGestureRecognizer(tap);
}
func focusOnEditBox() {
for sview in self.subviews {
if sview is UITextField {
sview.becomeFirstResponder();
}
}
}
}
Inspired by #Esqarrouth's answer at
Close iOS Keyboard by touching anywhere using Swift
I am aware this question has been asked before but the answer is not clear
The problem is that theUITableview is using data fromviewDidLoad method
where theNSMuatableArray has been allocated and initialised but contains void. But in the textfield method oftextFieldDidEndEditing,NSMutableArray do contain text from textField.
I have a single viewController and texField and tableview exist in it having dataSource set to the same viewController.
The problem is how can I pass that value toUITableView
viewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController<UITableViewDataSource>
#property (weak, nonatomic) IBOutlet UITextField *TextField;
#property NSString *content;
#property (nonatomic, strong) NSMutableArray *textFieldArray;
#end
viewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
-(BOOL)textFieldShouldReturn:(UITextField *) textField{
self.content = [textField text];
NSLog(#"content is %#", self.content);
[textField resignFirstResponder];
return YES;
}
-(bool)textFieldDidEndEditing:(UITextField *) textField {
[self.textFieldArray addObject:self.content];
[textField setText:#""];
NSLog(#"Array inside field did end editing is %#", self.textFieldArray);
return YES;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return self.textFieldArray.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
cell.textLabel.text = self.textFieldArray[indexPath.row];
return cell;
}
- (void)viewDidLoad {
[super viewDidLoad];
self.textFieldArray = [[NSMutableArray alloc]initWithObjects:#"add more task", nil];
NSLog(#"box in viewDidLoad ris %#", self.textFieldArray);
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
In your textFieldDidEndEditing: method after fetching the text from textfield reload the table view so that the new value get reflected. Do it this way:
[self.textFieldArray addObject:self.content];
[textField setText:#""];
// Your code is missing the following line
[tableView reloadData]; // tableView is instance of your table view
NSLog(#"Array inside field did end editing is %#", self.textFieldArray);
return YES;
Vivek's Answer is perfectly fine, except that fact you don;t need to reload table unless it's really necessary (extra processing time and all you know), so instead of reloading entire table you can add just one row, like this:
- (void) textFieldDidEndEditing:(UITextField *)textField {
[_tableDSArray addObject:textField.text];
[self.tableView insertRowsAtIndexPaths:#[[NSIndexPath indexPathForRow:tableDSArray.count-1 inSection:0]] withRowAnimation:UITableViewRowAnimationLeft];
}
-(bool)textFieldDidEndEditing:(UITextField *) textField {
[self.textFieldArray addObject:self.content];
[textField setText:#""];
[tableView reloadData]; //Reload tableview
return YES;
}
Call tableview reload in textFieldDidEndEditing delegate
-(bool)textFieldDidEndEditing:(UITextField *) textField {
[self.textFieldArray addObject:self.content];
[textField setText:#""];
[tableView setdelegate:nil];
[tableView setdatasource:nil];
[tableView setdelegate:self];
[tableView setdatasource:self];
[tableView reloadData];
NSLog(#"Updated With Entered Text:\n%#",self.textFieldArray);
return YES;
}
I am using UISearchbar in tableview controller in storyboard.
And searchbar returnKeyType is UIReturnKeySearch.
Its working fine with iOS7 but returnKeyType is not working with iOS8.
in iOS8, return key appears every time in keyboard.
I tried to set returnkeytype in viewDidLoad method of controller too.
What I need to do to set returnKeyType = UIReturnKeySearch in iOS8?
I think you can go with your hard codded logic for right now.
I will update if I will get better solution for your problem.
-(void)viewDidLoad {
[self setReturnKeyTypeSearchForView:searchBar];
}
-(void)setReturnKeyTypeSearchForView:(UIView *)view
{
for (id subView in view.subviews) {
if ([subView isKindOfClass:[UITextField class]]) {
[subView setReturnKeyType:UIReturnKeySearch];
}
else {
[self setReturnKeyTypeSearchForView:subView];
}
}
if ([view isKindOfClass:[UITextField class]]) {
[(UITextField *)view setReturnKeyType:UIReturnKeySearch];
}
}
Try making IBOutlet of your SearchBar
#property (weak, nonatomic) IBOutlet UISearchBar *searchBar;
and add the below line code to your viewDidLoad Method
// if u want Done return key and change accordingly.
_searchBar.returnKeyType = UIReturnKeyDone;
SearchViewController.h
//

Building a SearchView with UISearchBar and UITableView
this might helps you :)
I'm not sure if I understood your question correctly. You want to have "search" button instead of "return" button, right? There is a new SearchController in ios 8, give it a try:
YourTableViewController.h
#interface YourTableViewController : UITableViewController<UISearchResultsUpdating>
#end
And now the implementation:
YourTableViewController.m
- (void)viewDidLoad {
// initializing with the same controller as presenting
UISearchController *searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
searchController.searchResultsUpdater = self;
searchController.searchBar.frame = CGRectMake(searchController.searchBar.frame.origin.x, searchController.searchBar.frame.origin.y, searchController.searchBar.frame.size.width, 44.0f);
searchController.dimsBackgroundDuringPresentation = NO;
searchController.searchBar.delegate = self;
searchController.searchBar.returnKeyType = UIReturnKeySearch; //should be search by default.. you can change to whatever you want.
// adding searchBar into HeaderView
self.tableView.tableHeaderView = searchController.searchBar;
// just to be able to present results on the same controller
self.definesPresentationContext = YES;
}
You also have to implement method from UISearchResultsUpdating protocol:
- (void)updateSearchResultsForSearchController:(UISearchController *)searchController {
// you can leave it blank
}
EDIT: If it is not what you were looking for please comment, so I can update my answer accordingly
try this in viewDidLoad:
UITextField *txfSearchField = [yourSearchbar valueForKey:#"_searchField"];
if([txfSearchField conformsToProtocol:#protocol(UITextInputTraits)]) {
[txfSearchField setReturnKeyType:UIReturnKeyDefault];
}
I'm learning Xcode and programming for the IPad. I have a TableView and can display it using a button. I would rather display it when I click on a TextField. If I dismiss the first responder, the keyboard, how then do I display the tableView? I have not found a example that fits. Any direction would help.
It is just simple
just in UItextField delegate method create your tableview.But return No ,that will never show keyboard and write your tableview code there.
here your have to use user defined delegates.

I've created a UITableView using the presets using the UITableViewController option in the New File dialog. I set the style to grouped using the Interface Builder.
However, the table always shows up in plain style.
The data source consists of two sections with two items each and a section header. It all shows up OK, but the style is wrong. Via NSLog I validated that the style is really set to plain at runtime. Am I missing something?
EDIT: Here my code. As I mentioned the NSLog calls return the expected values.

EDIT: To help things, I included a screenshot of the Interface Builder (style set to group).
Updated:
Find
- (id)initWithFrame:(CGRect)frame style:(UITableViewStyle)style
in your controller, set there style = UITableViewStyleGrouped; before calling to super
If you don't have any code somewhere that calls the - (id)initWithStyle:(UITableViewStyle)style method of your view with the wrong style (which I kind of expect),
you could rewrite your init method to
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:UITableViewStyleGrouped];
return self;
}
First, though, you might try to ensure that you've saved your .xib in Xcode, clean and rebuild your app, so that you're sure that your changes are what's actually running on the device/simulator.
That's really crazy. I found a kind of a work around.
I added a standard UIViewController and implemented the protocols UITableViewDelegate and UITableViewDataSource on it.
In the XIB/NIB I removed the standard UIView and added a UITableView. I connected the view's outlets datasource and delegate to the File Owner object and the File Owner's view outlet to the UITableView.
Now I am able to set the style of the table to grouped. Everything works great so far. However, I don't get what's really different to using a UITableViewController...
