When you tap a row in a UITableView
, the row is highlighted and selected. Is it possible to disable this so tapping a row does nothing?
问题:
回答1:
For me, the following worked fine:
tableView.allowsSelection = NO;
This means didSelectRowAt#
simply won\'t work. That is to say, touching a row of the table, as such, will do absolutely nothing. (And hence, obviously, there will never be a selected-animation.)
(Note that if, on the cells, you have UIButton
or any other controls, of course those controls will still work. Any controls you happen to have on the table cell, are totally unrelated to UITableView\'s ability to allow you to \"select a row\" using didSelectRowAt#
.)
回答2:
All you have to do is set the selection style on the UITableViewCell
instance using either:
Objective-C:
cell.selectionStyle = UITableViewCellSelectionStyleNone;
or
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
Swift 2:
cell.selectionStyle = UITableViewCellSelectionStyle.None
Swift 3 and 4.x:
cell.selectionStyle = .none
Further, make sure you either don\'t implement -tableView:didSelectRowAtIndexPath:
in your table view delegate or explicitly exclude the cells you want to have no action if you do implement it.

Because I\'ve read this post recently and it has helped me, I wanted to post another answer to consolidate all of the answers (for posterity).
So, there are actually 5 different answers depending on your desired logic and/or result:
1.To disable the blue highlighting without changing any other interaction of the cell:
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
I use this when I have a UIButton - or some other control(s) - hosted in a UITableViewCell and I want the user to be able to interact with the controls but not the cell itself.
NOTE: As Tony Million noted above, this does NOT prevent tableView:didSelectRowAtIndexPath:
. I get around this by simple \"if\" statements, most often testing for the section and avoiding action for a particular section.
Another way I thought of to test for the tapping of a cell like this is:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// A case was selected, so push into the CaseDetailViewController
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (cell.selectionStyle != UITableViewCellSelectionStyleNone) {
// Handle tap code here
}
}
2.To do this for an entire table, you can apply the above solution to each cell in the table, but you can also do this:
[tableView setAllowsSelection:NO];
In my testing, this still allows controls inside the UITableViewCell
to be interactive.
3.To make a cell \"read-only\", you can simply do this:
[cell setUserInteractionEnabled:NO];
4.To make an entire table \"read-only\"
[tableView setUserInteractionEnabled:NO];
5.To determine on-the-fly whether to highlight a cell (which according to this answer implicitly includes selection), you can implement the following UITableViewDelegate
protocol method:
- (BOOL)tableView:(UITableView *)tableView
shouldHighlightRowAtIndexPath:(NSIndexPath *)indexPath
回答4:
To sum up what I believe are the correct answers based on my own experience in implementing this:
If you want to disable selection for just some of the cells, use:
cell.userInteractionEnabled = NO;
As well as preventing selection, this also stops tableView:didSelectRowAtIndexPath: being called for the cells that have it set. (Credit goes to Tony Million for this answer, thanks!)
If you have buttons in your cells that need to be clicked, you need to instead:
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
and you also need to ignore any clicks on the cell in - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
.
If you want to disable selection for the whole table, use:
tableView.allowsSelection = NO;
(Credit to Paulo De Barros, thanks!)
回答5:
As of iOS 6.0, UITableViewDelegate
has tableView:shouldHighlightRowAtIndexPath:
. (Read about it in the iOS Documentation.)
This method lets you mark specific rows as unhighlightable (and implicitly, unselectable) without having to change a cell\'s selection style, messing with the cell\'s event handling with userInteractionEnabled = NO
, or any other techniques documented here.
回答6:
You can also disable selection of row from interface builder itself by choosing NoSelection
from the selection
option(of UITableView Properties) in inspector pane as shown in the below image
回答7:
FIXED SOLUTION FOR SWIFT 3
cell.selectionStyle = .none
回答8:
In case anyone needs answer for Swift:
cell.selectionStyle = .None
回答9:
If you want selection to only flash, not remain in the selected state, you can call, in
didSelectRowAtIndexPath
the following
[tableView deselectRowAtIndexPath:indexPath animated:YES];
so it will flash the selected state and revert.
回答10:
In your UITableViewCell
\'s XIB in Attribute Inspector set value of Selection
to None
.
回答11:
From the UITableViewDelegate
Protocol you can use the method willSelectRowAtIndexPath
and return nil
if you don\'t want the row selected.
In the same way the you can use the willDeselectRowAtIndexPath
method and return nil
if you don\'t want the row to deselect.
回答12:
This is what I use ,in cellForRowAtIndexPath
write this code.:
cell.selectionStyle = UITableViewCellSelectionStyleNone;
回答13:
Objective-C:
Below snippet disable highlighting but it also disable the call to
didSelectRowAtIndexPath
. So if you are not implementingdidSelectRowAtIndexPath
then use below method. This should be added when you are creating the table. This will work on buttons andUITextField
inside the cell though.self.tableView.allowsSelection = NO;
Below snippet disable highlighting and it doesn\'t disable the call to
didSelectRowAtIndexPath
. Set the selection style of cell to None incellForRowAtIndexPath
cell.selectionStyle = UITableViewCellSelectionStyleNone;
Below snippet disable everything on the cell. This will disable the interaction to
buttons
,textfields
:self.tableView.userInteractionEnabled = false;
Swift:
Below are the Swift
equivalent of above Objective-C
solutions:
Replacement of First Solution
self.tableView.allowsSelection = false
Replacement of Second Solution
cell?.selectionStyle = UITableViewCellSelectionStyle.None
Replacement of Third Solution
self.tableView.userInteractionEnabled = false
回答14:
Try to type:
cell.selected = NO;
It will deselect your row when needed.
In Swift3 ...
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let r = indexPath.row
print(\"clicked .. \\(r)\")
tableView.cellForRow(at: indexPath)?.setSelected(false, animated: true)
}

I\'ve been battling with this quite profusely too, having a control in my UITableViewCell
prohibited the use of userInteractionEnabled
property. I have a 3 cell static table for settings, 2 with dates, 1 with an on/off switch. After playing about in Storyboard/IB i\'ve managed to make the bottom one non-selectable, but when you tap it the selection from one of the top rows disappears. Here is a WIP image of my settings UITableView:
If you tap the 3rd row nothing at all happens, the selection will stay on the second row. The functionality is practically a copy of Apple\'s Calendar app\'s add event time selection screen.
The code is surprisingly compatible, all the way down to IOS2 =/:
- (NSIndexPath *)tableView: (UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row == 2) {
return nil;
}
return indexPath;
}
This works in conjunction with setting the selection style to none, so the cell doesn\'t flicker on touch down events
回答16:
for swift deselection
cell.selectionStyle = .None
回答17:
We can write code like
cell.selectionStyle = UITableViewCellSelectionStyleNone;
but when we have custom cell xib above line give warning at that time for
custom cell xib
we need to set selection style None from the interface builder
回答18:
You just have to put this code into cellForRowAtIndexPath
To disable the cell\'s selection property:(While tapping the cell).
cell.selectionStyle = UITableViewCellSelectionStyle.None
回答19:
try this
cell.selectionStyle = UITableViewCellSelectionStyleNone;
and
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
and you can also set selection style using interfacebuilder.
回答20:
I am using this, which works for me.
cell?.selectionStyle = UITableViewCellSelectionStyle.None
回答21:
While this is the best and easiest solution to prevent a row from showing the highlight during selection
cell.selectionStyle = UITableViewCellSelectionStyleNone;
I\'d like to also suggest that it\'s occasionally useful to briefly show that the row has been selected and then turning it off. This alerts the users with a confirmation of what they intended to select:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:NO];
...
}
回答22:
You Can also set the background color to Clear to achieve the same effect as UITableViewCellSelectionStyleNone
, in case you don\'t want to/ can\'t use UITableViewCellSelectionStyleNone
.
You would use code like the following:
UIView *backgroundColorView = [[UIView alloc] init];
backgroundColorView.backgroundColor = [UIColor clearColor];
backgroundColorView.layer.masksToBounds = YES;
[cell setSelectedBackgroundView: backgroundColorView];
This may degrade your performance as your adding an extra colored view to each cell.

Directly disable highlighting of TableViewCell into storyboard
回答24:
To disable the highlighting of the UItableviewcell
cell.selectionStyle = UITableViewCellSelectionStyleNone;
And should not allow the user to interact with the cell.
cell.userInteractionEnabled = NO;
回答25:
You can use this
cell.selectionStyle = UITableViewCellSelectionStyleNone;
回答26:
You can use ....
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
回答27:
cell.selectionStyle = UITableViewCellSelectionStyleNone;
回答28:
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
[cell setSelected:NO animated:NO];
[cell setHighlighted:NO animated:NO];
Happy coding !!!
回答29:
You can also do it from the storyboard. Click the table view cell and in the attributes inspector under Table View Cell, change the drop down next to Selection to None.

Swift Solution w/ Custom Cell:
import Foundation
class CustomTableViewCell: UITableViewCell
{
required init(coder aDecoder: NSCoder)
{
fatalError(\"init(coder:) has not been implemented\")
}
override init(style: UITableViewCellStyle, reuseIdentifier: String?)
{
super.init(style: style, reuseIdentifier: reuseIdentifier)
self.selectionStyle = UITableViewCellSelectionStyle.None
}
}
