I have a UITableView tableHeaderView defined in a nib file. The tableHeaderView contains a UITextView. The UITextView's delegate is set to the UITableViewController and the UITableViewController supports the UITextViewDelegate protocol. The UITableViewController is setting various properties in the tableHeaderView including the UITextView's text and that all works fine. But textFieldShouldReturn:(UITextField *)textField in the UITableViewController never gets called and I can't get the keyboard to close after I've tapped the UITextView.
I've tried every suggestion I can find in the docs and various posts, but no luck. None of the examples I've found have this specific case of a UITextView inside a tableHeaderView.
Is there something special I need to do. Has anyone done this successfully?
I've tried setting the UITextView delegate in code, but no luck.
#class Decision;
#interface DecisionDetailViewController : UITableViewController <UINavigationControllerDelegate, UITextViewDelegate> {
Decision *decision;
UIView *tableHeaderView;
UITextView *nameTextField;
}
#property (nonatomic, retain) Decision *decision;
#property (nonatomic, retain) IBOutlet UIView *tableHeaderView;
#property (nonatomic, retain) IBOutlet UITextView *nameTextField;
#end
#implementation DecisionDetailViewController
#synthesize decision;
#synthesize tableHeaderView;
#synthesize nameTextField;
- (void)viewDidLoad {
self.navigationItem.rightBarButtonItem = self.editButtonItem;
if (tableHeaderView == nil) {
[[NSBundle mainBundle] loadNibNamed:#"DecisionDetailHeader" owner:self options:nil];
self.tableView.tableHeaderView = tableHeaderView;
}
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[nameTextField resignFirstResponder];
return YES;
}
textFieldShouldReturn is a method of UITextFieldDelegate and not UITextViewDelegate. Thats probably your problem.

I am having issues when I want to assign UIPicker as inputView of UITextField. It shows error " Assignement to readonly property". Please help as I think it is not related to property sythesizing.
I have added my code below:
#interface DriverWaitingDetails : UIViewController<UITextFieldDelegate,UIPickerViewDataSource, UIPickerViewDelegate>
{
IBOutlet UILabel *baseLabel;
IBOutlet UITableView *driverTableView;
IBOutlet UIPickerView *basePicker;
}
#property(nonatomic, retain) IBOutlet UIPickerView *basePicker;
#property(nonatomic,retain)IBOutlet UILabel *baseLabel;
#property(nonatomic,retain)IBOutlet UITableView *driverTableView;
#end
Implementation Code:-
-(void)viewDidLoad
{
basePicker=[[UIPickerView alloc] initWithFrame:CGRectMake(0,100,320, 500)];
self.navigationItem.title=#"Driver Table";
baseLabel.userInteractionEnabled = YES;
basePicker.delegate = self;
basePicker.dataSource = self;
[basePicker setShowsSelectionIndicator:YES];
baseLabel.inputView=nil;
[super viewDidLoad];
}
Attached Screenshot:-
You are setting the input view of UILabel.
You declared baseLabel as UILabel not UITextField.
IBOutlet UILabel *baseLabel;
You have declared
IBOutlet UILabel *baseLabel;
UILabel inherits from UIView : UIResponder : NSObject and the property is defined in UIResponder:
#property (readonly, retain) UIView *inputView
As the property inputView is read only, you cannot assign any value to it.
I would like to NSLog something when my UITextView is done editing.
I've tried
- (BOOL)textViewShouldEndEditing:(UITextView *)textView
and
- (void)textViewDidEndEditing:(UITextView *)textView
neither worked.
fix:
myTextView.delegate = self;
do you set the delegate of your textview?
fix:
set delegate in .h file like this:
#import <UIKit/UIKit.h>
#interface TextViewController : UIViewController <UITextViewDelegate>
{
UITextView *textView;
}
#property (nonatomic, retain) UITextView *textView;
#end
If you are using UITextField instead make sure to use UITextFieldDelegate and not UITextViewDelegate. And this method instead, that fixed my problems.
- (void)textFieldDidEndEditing:(UITextField *)textField
I'm new on this, and I would like to get some advice because I don't know what I'm doing wrong.
I want to make an app in xcode, with a UIView with some items, and when you do something, another UIView (smaller than the first) pops up above the first UIView. The popup UIView would be a customized class.
I have started with the UIViewController template and the initial UIView, and I have linked all the items in the .storyboard, and it works. But when I create my own UIView class (from objective-C class), put the second UIView over the first in the storyboard and link it to my class, something goes wrong.
The UIView appears, but when I try to set it to hidden, it doesn't answer. It's like it's not receiving the messages, so I think I don't link it well programmatically and just appears because of the storyboard.
I don't know if I have to create another UIViewController instead of the UIView, or if this is the correct path.
Can anybody explain me a little, or just write a little code snippet with the instantiation of the second view and adding it?
Lots of thanks!!
(I paste some code, of the declaration in .h and instantiation in .m)
#import <UIKit/UIKit.h>
#import "EditView.h"
#interface ReleaseViewController : UIViewController <UIWebViewDelegate, UISearchBarDelegate> {
IBOutlet UIWebView *web;
IBOutlet UISearchBar *search;
IBOutlet EditView *evHack;
}
#property (nonatomic, retain) IBOutlet UIWebView *web;
#property (nonatomic, retain) IBOutlet UISearchBar *search;
#property (nonatomic, retain) IBOutlet EditView *evHack;
#end
- (void)viewDidLoad
{
[super viewDidLoad];
search.delegate = self;
web.delegate = self;
evHack = [evHack initWithFrame:CGRectMake(0, 44, 320, 377)];
[evHack setHidden:YES];
}
EditView Class (I still have nothing):
#import <UIKit/UIKit.h>
#interface EditView : UIView
#end
#import "EditView.h"
#implementation EditView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
NSLog(#"View created");
}
return self;
}
/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
// Drawing code
}
*/
#end
initWithFrame only works when you alloc/init an app. If its already initialized, in this case by the storyboard, just set its frame:
evHack.frame = CGRectMake(0,44, 320, 377);
I don't know what it looks like in IB, But setting its frame in code may be redundant if you set it in IB too. To check whether evHack is hooked up right, NSLog evHack in viewDidLoad. If you get nil back, it's not hooked up right.
I want to hide keyboard when a user presses return in UITextView object in iphone. However, mysteriously this is not working for UITextView but working for UITextField. I am unable to figure out why...
This is what I did:
1) I created a view based application in XCode4.
2) in .xib created UITextView, UITextField and UIButton objects
3) Marked both UITextField and UITextView delegates to File's Owner in Outlets
4) Added <UITextFieldDelegate> to #interface UIViewController in .h
5) Added textFieldShouldReturn function in .m
Here are the codes:
.h file
#interface keyboardDisappearViewController : UIViewController <UITextFieldDelegate>
{
UITextView *textBoxLarge;
UITextField *textBoxLittle;
}
#property (nonatomic, retain) IBOutlet UITextView *textBoxLarge;
#property (nonatomic, retain) IBOutlet UITextField *textBoxLittle;
- (IBAction)doSomething:(id)sender;
#end
.m file
- (BOOL) textFieldShouldReturn:(UITextField *)theTextField
{
NSLog(#"textFieldShouldReturn Fired :)");
[textBoxLarge resignFirstResponder];
[textBoxLittle resignFirstResponder];
return YES;
}
Amazingly, the keyboard is disappearing in case of textBoxLittle (UITextField) but not in case of textBoxLarge(UITextView)
As a further check I, made the button to call function doSomething
- (IBAction)doSomething:(id)sender {
[textBoxLarge resignFirstResponder];
[textBoxLittle resignFirstResponder];
}
When I am pressing the button, keyboard is disappearing in both textboxes.
Its driving me nuts why textFieldShouldReturn is working for small textbox, but NOT for large textbox.
Please Help!
Three things:
Make your view implement UITextViewDelegate.
#interface keyboardDisappearViewController : UIViewController
<UITextFieldDelegate, UITextViewDelegate>
Add the following method:
- (BOOL)textView:(UITextView *)textView
shouldChangeTextInRange:(NSRange)range
replacementText:(NSString *)text
{
if ([text isEqualToString:#"\n"])
{
[textView resignFirstResponder];
}
return YES;
}
Set the file's owner as delegate for the UITextView in the interface builder.
(BTW: Solution copied from the comments to the previous answer, as it took me a while to extract. I though others could benefit from my experience.)
You need to write code in UITextViewDelegate and assign it to your class.
Simple trick
Set delegate for your text view and then
doSomething
{
}
action connect to ext view for control event didEndOnExit and tuchupinside
// To dismiss key board when user clicks enter/return
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
if([text isEqualToString:#"\n"])
{
[textView resignFirstResponder];
return NO;
}
return YES;
}
Use this code
Inherit UITextViewDelegate protocol in your Viewcontroller add the text
#interface YourViewController () <UITextViewDelegate>
In viewDidLoad set yourself as a delegate:
yourUITextView.delegate = self;
Implement the delegate method below:
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
return NO;
}
Key Points
Someone needs to be listening for the Return Key press
UITextFieldDelegate
textFieldShouldReturn(textField : UITextField)
Someone needs to manually dismiss the keyboard
resignFirstResponder()
#1: Create a UITextFieldDelegate and assign it as the delegate to your UITextField -
exampleTextField.delegate = yourUITextFieldDelegate;
#2: Have 'yourUITextFieldDelegate' contain the following -
func textFieldShouldReturn(textField : UITextField) -> Bool {
self.titleField.resignFirstResponder(); //Here's the key!!!!!
return true; //true just says 'default behavior'
}
If you came here looking for the Swift solution, like I did, here you are :)
extension keyboardDisappearViewController : UITextViewDelegate {
func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {
if(text == "\n") {
textView.resignFirstResponder()
}
return true
}}
You have coded in the .h file:
#interface keyboardDisappearViewController : UIViewController <UITextFieldDelegate>
{
UITextView *textBoxLarge;
UITextField *textBoxLittle;
}
#property (nonatomic, retain) IBOutlet UITextView *textBoxLarge;
#property (nonatomic, retain) IBOutlet UITextField *textBoxLittle;
- (IBAction)doSomething:(id)sender;
#end
It should be:
#interface keyboardDisappearViewController : UIViewController <UITextFieldDelegate>
{
UITextView *textBoxLarge;
UITextField *textBoxLittle;
}
#property (nonatomic, retain) IBOutlet UITextField *textBoxLarge;
#property (nonatomic, retain) IBOutlet UITextField *textBoxLittle;
- (IBAction)doSomething:(id)sender;
#end
I'm having a problem. I have a UIView, that looks like this :
In that view controller I implemented the "touchesBegan:withEvent:" method, but the method is only getting triggered when I touch the bar at the bottom of the view , nothing happens when I touch the table.
How could I change this behavior to be able to detect the touches that occur in the table too ?
This is the code that basically declares that UIViewController:
#import <Foundation/Foundation.h>
#import <QuartzCore/QuartzCore.h>
#interface TripSearchDetailViewController : UIViewController
{
//Parent of this sub-view.
UIViewController *parentController;
//GUI elements
UITableView *tableView;
UIButton *backButton;
}
//Button actions
- (IBAction) goBack:(id) sender;
- (IBAction) showDatePicker:(id) sender;
//Class Methods.
- (void) presentDatePicker;
#property (nonatomic, retain) UIViewController *parentController;
#property (nonatomic, retain) IBOutlet UITableView *tableView;
#property (nonatomic, retain) IBOutlet UIButton *backButton;
#end
It looks like you've got a UITableViewController, not a UIViewController. Your table view is intercepting and handling touches before they make it up to your view controller. You'll need to subclass UITableView, override it's -touchesBegan:withEvent: method, and then create a standard UIViewController that adds your new subclass to the view hierarchy.
I think it could possibly help to implement the method hitTest:withEvent: in your TripSearchDetailViewController. If you just return true in this method your touch should be recognized.
