I have a very strange problem,I don't know whether it is awkward to normal behavior of cells or not,it seems as if it is so!Hence I am giving it up to some one who can answer, apologize if any thing stupid in asking this question.Normally,when we touch a table view cell,what happens is it navigates to a view controller/a controller that is coded.Now what's strange here is it is not responding to selection,or touch.I have checked whether or not allows selection while editing is selected in IB or not.I have selected it,now the twist here is when I am touching a table view cell it is not responding,instead when I swipe it horizontally/when I long press the cell,it is navigating,really surprised at this strange behavior!I don't understand the reason why I need to swipe it to make selection of cell in table view work.This is also happening with button present below the table view!
I have searched for issues similar to my case,but I found just one question there it was suggested to check for this method,
-(NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
But i haven't implemented that method at all,what I have actually is a tab bar with several items,where I have a controller called AddController,for accessing several attributes and strings etc.. declared in the controller,I am subclassing it as follows:
#interface ViewController : AddController
Now because it was specified in the question I saw,i.e. the link I gave,to check whether u are copying the same code in subclass controller page,I spoke about subclassing and what I did,hope every one understands it!
Can any one please guide me how to get out of this issue,and make table view cell respond to normal touches,any help is greatly appreciated!
Thanks all in advance :)
After doing some research I'm pretty sure that it is the UITapGestureRecognizer on the tableView caused you the problem. If you were like me having the text field in the cell and using the UITapGestureRecognizer to close the keyboard, here's my solution:
In the view that you implemented UITextFieldDelegate
(In my case I have a custom UITableViewCell called TextFieldCell),
Declare a UITapGestureRecognizer as a property:
#interface TextFieldCell : UITableViewCell <UITextFieldDelegate>
{
UITextField *theTextField;
UITapGestureRecognizer *gestureRecognizer;
}
#property (nonatomic,retain) UITextField *theTextField;
#property (nonatomic,retain) UITapGestureRecognizer *gestureRecognizer;
And initialize it in your view:
self.gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(closeKeyboard:)];
In the - (void)textFieldDidBeginEditing:(UITextField *)textField method, use superView to move up to your tableView and call addGestureRecognizer:
[self.superview.superview addGestureRecognizer:gestureRecognizer];
And in the - (void)textFieldDidEndEditing:(UITextField *)textField, just remove the gesture recognizer:
[self.superview.superview removeGestureRecognizer:gestureRecognizer];
This will totally solve the problem.
Did you use a UITapGestureRecognizer on your tableView? I had the exactly same problem as you did today, and then I figured out that it was the gesture recognizer that blurs my intention for selecting a row by tapping. When I removed it, the tableView was back to normal.
Hope this helps.
I had this same problem and solved it by ticking "Scrolling Enabled" in the table view attributes.
My table view doesn't need scrolling, so it doesn't affect the app in any other way, except now I don't get the first unresponsive tap after a swipe gesture.

I know this question has been asked before but I couldn't find an answer that applied to my problem.
I've got a UITableViewController that has a third row that is filled with a UITextView.
I'm quite happy with the way it looks and the way text is typed into it.
However I'm unable to find a way of getting rid of the keyboard once the user is done entering text. I'd like to be able to use the return button for actual \n in the text.
I've gotten this far that pressing the upper two rows will make the textView te resignFirstTransponder but is there a way to catch a tap on the greyish background?
This is all in a UITableViewController loaded from a nib file.
Btw, I'm quite new to iOS programming so the more elaborate your answer the better :)
Thanks!
A pattern many apps follow is to show a horizontal bar with buttons on it just above the keyboard. It can contain a done button clicking on which you can hide the keyboard. And of course you will have to create that horizontal view yourself.
Another way would be to enable a touch recognizer elsewhere, and on a tap outside hide the keyboard
One alternative would be to add a toolbar to the keyboard with something like a "done" button that will dismiss it. You can find some sample code about that here. One second approach would be to dismiss the keyboard when the user selects a different cell or even when the tableView scrolls. In order to do that, you can add relevant code in -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath or in -(void)scrollViewDidScroll:(UIScrollView *)scrollView respectively.
This can get a little tricky if your new at iOS. The way I handle a UITextView in a UITableViewCell is I make a custom UITableViewCell subclass with an outlet for the UITextView.
Then set your cell in interface builder to be of that subclass. In the CellForRowAtIndexPath:
set the delegate to self. Then in the DidSelectRowAtIndexPath you call the delegate for the TextView based on the indexPath, this way the keyBoard will dismiss for the correct row if you touch the background. If you want it to dismiss when the user touches any cell just call the delegate without specifying the indexPath. The Delegate is TextViewShouldEndEditing:.Ill post some code if you want.
I need to have a UIButton inside a UITableViewCell, everything works fine except when I touch inside the button and move my finger, the table does not scroll.
I tried to subclass UIButton and in touchesMoved: method send the same message to self.nextResponder, or call touchesCancelled and hope it will pass the touch event to next responder, they both do not work.
Is there any good way to solve this problem? Currently I am adding a UIView on top of the UITableViewCell, and detecting touch events manually, passing result to the button or the rest of the cell respectively, but this is a little bit dirty.
What you can try is setting the delaysContentTouches property of the UITableView to YES.
Additionally you can set the canCancelContentTouches to YES.
If the value of this property is NO, the scroll view does not scroll
regardless of finger movement once the content view starts tracking.
Source: UIScrollView Class Reference
Try:
_yourTableView.delaysContentTouches = YES;
_yourTableView.canCancelContentTouches = YES;
The best way is to make a custom cell and do your work neatly.

I have a standard UITableViewController. In the cellForRowAtIndexPath I add a subview to cell.contentView. This UIView itself contains a UITextField object. This object will not respond to touches. I have set the delegate to the UIView and implemented all the methods. I have also set userInteractionEnabled = YES. When I tap the UITextField nothing happens! I feel it's being absorbed by the cell. What would be the easiest, least messy fix?
Best,
Joris
EDIT: Sorry, see my answer. I solved it.
I'm an idiot. Sorry for wasting everyone's time. I hadn't properly said the UIView's frame. It of course did display the UI elements, but wouldn't respond to them.
Try just adding the textfield as a subview of the cell, this is what I have done in a couple of my apps and had no problems with it
In your tableView, try to set
allowsSelection = NO;
Try setting the editing property of the table view to YES.

Editing a UITextField inside a UITableViewCell fails
I'm pretty new to iPhone development, so please excuse my ignorance. I've googled this a bit and so far come up with nothing useful. Here is what I would like to do:
I would like a subview to popup(with the rest of the screen showing in the background) when a UITextField is touched. The popup is a calculator UIView that I created in the IB. It seems it is better to have a popup show than a customized keyboard, due to Apple's developer guidelines.
Here is my question. How do I capture the touch on the UITextField and how do I show the subview?
I have tried things like below to show the subview, with no luck:
CustomCalculator *customCalc = [[CustomCalculator alloc] initWithNibName:#"CustomCalculator" bundle:nil];
UIViewController *calcController = [self.customCalc.view];
[self.view addSubview:calcController.view];
Use the delegate method:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
//Add your subview here
return NO; //this will stop the keyboard from poping up
}
This way when someone taps the textfield, your view will popup instead of the keyboard.
Now once the user is interacting with your view, you will have to manipulate the string in the textfield.text property directly as a reaction to the User tapping buttons in your view.
Implement the UITextFieldDelegate and the method for it is
-(void) textFieldDidBeginEditing:(UITextField *)textField
The above method is fired when you touch the UITextField. You may then position the UIPopoverController (I'm guessing that is what you're using to show the view in a popup) and as soon as you're done there pass the values back to the UITextField. Hence the popover's/viewcontroller presented's delegate should be your textfield object.
EDIT: After seeing the other answer below it struck me that I forgot to tell you how to stop the keyboard from showing. Just make this the first line in the method I've mentioned above:
[textField resignFirstResponder];
I have a UITextView in my custom UITableViewCell and the issue is that when I tap on it it won't respond to the didSelectRowAtIndexPath or even swipe events. How can I fix this? This UITextView is not editable. The reason why I use this over a UITextField is because I want to be able to detect links easily.
I realize this is an old question, but I recently had the same issue. The fix in my case was to simply turn off "User Interaction Enabled" for the UITextView.
you need to forward the touch messages from UITableView to UITextView
UITextView inside UITableView
The first idea that came to mind...
In cellForRow set the textfield tag as the indexpath.row
Implement - (void)textViewDidBeginEditing:(UITextView *)textView
Based on this textView.tag, call the selectrow
[self.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:textView.tag inSection:<#(NSUInteger)#>]
animated:<#(BOOL)#> scrollPosition:<#(UITableViewScrollPosition)#>]
I don't know if it's what are you looking for But in my case i had a custom cell with UIImage, and UITextView and only when I clicked on UIImageView i got didSelectRowAtIndexPath recogniser. Make sure UITextView is user interections unable like that to fix the problem
Check if your TableView Selection property is set to NO
Wrong :
tableView.allowsSelection = false
DidSelect Wont be called
It has to be:
tableView.allowsSelection = true
Also Check your Nib
