How can I customize the accessory disclosure image in a UITableViewCell? - cocoa-touch

Question

I would like to use a custom version of the standard disclosure accessory image in my UITableView. How can I do this? I'm hoping that sub-classing UITableViewCell is not necessary for something this basic.

Answer 1

You'll need to create a custom view and assign it to the accessoryView property of the UITableViewCell object. Something like:
myCell.accessoryView = [[ UIImageView alloc ]
initWithImage:[UIImage imageNamed:#"Something" ]];

Answer 2

- (UITableViewCell *)tableView:(UITableView *)tView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UIImage *indicatorImage = [UIImage imageNamed:#"Arrow.png"];
cell.accessoryView =[[[UIImageView alloc] initWithImage:indicatorImage] autorelease];
return cell;
}
well i do this with the help code given above

Answer 3

I ran into the same problem as Greg--the accessory view doesn't track (if you use an UIImageView)
I solved it like this:
UIImage * image = [ UIImage imageNamed:#"disclosure-button-grey.png" ] ;
UIControl * c = [ [ UIControl alloc ] initWithFrame:(CGRect){ CGPointZero, image.size } ] ;
c.layer.contents = (id)image.CGImage ;
[ c addTarget:self action:#selector( accessoryTapped: ) forControlEvents:UIControlEventTouchUpInside ] ;
cell.accessoryView = c ;
[ c release ] ;

Answer 4

There is a nice example from Apple showing how to use UIControl to fulfill this kind of accessoryView customisation.
Overriding - (void)drawRect:(CGRect)rect in UIControl is not the easiest way, but gives you lots of flexibility to style nice accessory views.

Swift 4 & 5:
This worked for me:
class MyCell: UITableViewCell {
// boilerplate...
fileprivate func commonInit() {
// This is the button we want, just need to change the image.
accessoryType = .detailButton
}
open override func layoutSubviews() {
super.layoutSubviews()
// Grab the "detail" button to change its icon. Functionality is set in the delegate.
if let submitButton = allSubviews.compactMap({ $0 as? UIButton }).first {
submitButton.setImage(#imageLiteral(resourceName: "icons8-enter-1"), for: .normal)
}
}
// everything else...
}
Best of all, this lets me use tableView(_:accessoryButtonTappedForRowWith:) to handle the button actions.
I used this for the button, but the same technique works for the disclosure image, [since/so long as] there is only one class in that branch of the hierarchy tree of the element you want to touch.
Oh, right, my code calls this:
extension UIView {
var allSubviews: [UIView] {
return subviews.flatMap { [$0] + $0.allSubviews }
}
}

Answer 6

I'd do it as follows:
UIImageView *chevronImgVw = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"chevron_accessory_vw_img.png"]];
chevronImgVw.frame = CGRectMake(cell.accessoryView.frame.origin.x, cell.accessoryView.frame.origin.y, 10, 20);
cell.accessoryView = chevronImgVw;

Answer 7

In swift 4 & 5
myCell.accessoryView = UIImageView(image: UIImage(named: "Something"))

Answer 8

NOTE: Do NOT set a custom cell to tag:0. That tag is reserved for the textLabel view. If you set tags in Xcode Storyboard, you must set tags for custom views/labels to 1 or higher.
Note Apple's example:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath (NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"MyIdentifier"];
UILabel *label;
label = (UILabel *)[cell viewWithTag:1];
label.text = [NSString stringWithFormat:#"%d", indexPath.row];
label = (UILabel *)[cell viewWithTag:2];
label.text = [NSString stringWithFormat:#"%d", NUMBER_OF_ROWS - indexPath.row];
return cell;
}

Answer 9

I tried the above code and it doesn't seem to work anymore, maybe due to the age of this post so I'll throw down my line that gave me the customized accessory view.
[cell setAccessoryView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"arrowBtn"]]];
Hope someone finds this useful.
