after upgrading to iOS 9 (worked fine in iOS 8), I am having trouble clicking UIBUttons and editing UITextFields inside custom UITableViewCells.
I have an UITableView with custom UITableViewCells. These cells are loaded like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
...
controller=[[PresetRowViewController alloc] initWithNibName:#"PresetRowViewController" bundle:nil];
...
return (UITableViewCell *)controller.view;
}
The cells show fine, but I cannot click in any UIButton or edit any UITextField inside them.
Any ideas?
Thanks
Try checking for gesture recognizers (ie. view.gestureRecognizers = nil;) for various views (the button, cell itself). Also make sure button.userInteractionEnabled = YES; and cell.userInteractionEnabled = YES; Finally, make sure there's no invisible views overtop of the button/cell.
Try to bring the subviews in the customized table view cell to the front.
I had this same issue. Apple changed how UITableViewCells work in iOS 9. It was fixed for me by dragging in a new UITableViewCell into the Xib and moving everything over. See: https://stackoverflow.com/a/32826526/101923

In IB I've put an View Controller with a Table View and a Navigation bar. Because I want to change the actions (and text) on the buttons when the table is being edited, I decided to create the button programatically.
In the implementation file, I've set up the button (copied from another post on Stackoverflow):
- (void)viewDidLoad {
[super viewDidLoad];
self.title = #"Title";
UIBarButtonItem *editButton = [[UIBarButtonItem alloc] initWithTitle:#"Edit" style:UIBarButtonItemStylePlain target:self action:#selector(EditTable:)];
self.navigationItem.rightBarButtonItem = editButton;
}
But when I run this in the simulator, I don't see the button. Is this the right approach for my goal? Or what am I doing wrong?
Later, I also want to add a Back, Add and Done button.
You probably did not created iboutlet for that navigation bar. Self.navigationItem is a property which is available on any viewcontroller and is applied only if there is a navigationcontroller which manages your viewcontrollers stack. There is no relation to manually created navigationItems..
I assume that either outlet for that navigationbar or going to storyboard, click your viewcontroller and then Editor->Embed In->navigation controller will help you to achieve disered results.
I just upgraded to Xcode 6.0.1. I've got an iOS7 app that has a custom tableViewCell that uses:
- (void)willTransitionToState:(UITableViewCellStateMask)state {
//...code
}
Now, when I place the cell in edit mode in my viewController, the value of "state" is some bizarre new value, "2147483649"
Did something change in the stateMask value, or in how you place a cell in edit mode ?
Got the same problem, only with iOS8 (didn't have this problem on iOS 7.1.1)I noticed that this happens when my tableView is implementing its dataSource delegate method's for reordering cells:
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath;
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath;
When I delete these methods from my tableView's delegate class, I got the correct state from UITableViewCell's [willTransitionToState:] method.
I submitted a bug to apple, bug's number is 18536460, will add a link when available
I am developing a cocoa app where i need to create Menu and Submenu's in my application.
I have attached a screenshot designed using flex. How can i do the same in cocoa.
Any help would be appreciated.
Thanks.
Your question itself is incomplete,though will try to match the solution your expecting…The screenshot you posted(you never mentioned the source of the screenshot you have taken,by analysing the design i edited in your question as “Flex”) looks like you don’t want to deal with NSMenuItem and NSMenu classes for the drop down menus…
Solution 1: Make a custom View(probably subview of NSView like popview) that handles input, displaying labels,imageviews etc.
==> Basically,both the menu bar and menu item are wrapped to an NSView And the drop down menu is wrapped to an NSPanel…Well as per the design you have to use NSView,because you will be able to add the corner you like and yes,there is a possibility of adding back ground colour as well…The menu item actually has subviews of NSTextView. If its a menu bar item then it only has one text subview for its title, and if its a sub menu item then it has 3 text subviews, one for the check mark, one for the title and one for the hot key list…No need to worry about the handling the events,the respective classes do their own event handling…It’s quite a complicated solution,but matches your requirement…
Found some example for you,check out this code which is in C++.
Solution 2: NSTableView with custom cell.Could be fugly, but maybe worth a shot.
==> Create a custom NSTableCellView/NSCell,with NSImageView(for icons like Pen), NSTextView(for the text “Pen Thickness”) and one more NSImageView(for the right corner icon) as it's subviews …You have to perform one of the two actions when user hits your cell…(1) If you would like to have the submenu,then again that cell should create one more NSTableView using the origin (cell.frame.origin.x+cell.frame.size.width, cell.frame.origin.y)…(2) If there is no submenu,perform the direct task...
Example: Assume "MenuItemCell" is the custom class name,in the delegate method tableView
willDisplayCell add the cell...
- (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row {
MenuItemCell *cell = [tableView makeViewWithIdentifier:tableColumn.identifier owner:self];
result.imageView.image = //ur image
result.textView.setString//;
result.imageView.image = //corner image icon,if you would like to have submenu upon clicking this cell.
return result;
}
On selecting the custom cell,
- (BOOL)tableView:(NSTableView *)tableView shouldSelectRow:(NSInteger)rowIndex
{
NSLog(#"%i tapped!", rowIndex);
NSTableCellView *selectedRow = [tableView viewAtColumn:0 row:rowIndex makeIfNecessary:YES];
//if you would like to have the submenu,display one more NSTableView,based on the cell origin as i described above...don't forget to add the animation..
return YES;
}
Happy Coding.. :-)
I have an view-based TableView with an image and a NSTextField. I've got some links inside my NSTextField and I have tried many options (http://developer.apple.com/library/mac/#qa/qa2006/qa1487.html, dsclickableurltextfield) but nothing works out, because it seems that these options only fit to an cell-based tableview. I also watched the wwdc 2010 cocoa tips and tricks with an good explanation for links inside tableviews. But the custom NSTextFieldCell doesn't work for me. The mouse-events don't reach the custom class and for that reason nothings happens...
I hope you've got the right idea to solve this problem...
You need to add this to your table view's delegate:
- (BOOL)tableView:(NSTableView *)tableView shouldTrackCell:(NSCell *)cell forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
{
return YES; // required for specific tracking control in our NSTextFieldCell
}
I've got a problem. [for which the only example I can find was shown during one of the WWDC 2011 presentations ("Maximising Productivity in Xcode 4"), but there is no source available (it was an app called Birdathon). Everything else I come up with is for iOS, and doesn't translate across.]
Basically, I have some view-based NSTableViews, and currently lay out the image / text fields within my NSTableCellView directly in the column. I've got a subclass of NSTableCellView which gives me the outlets to assign values to each of the text fields I use within that cell. The DataSource and Delegate are implemented and working fine - the TableView with my custom NSTableViewCell works fine.
My problem is I'd like to use the same cell in multiple different tables. Rather than have to recreate the same layout each time, I feel I should be able to draw the NSTableCellView just once in IB. [- and indeed, the Birdathon example I mentioned seemed to show the NSTableCellView being laid out in it's own NIB.]
I've found the answer for iOS in many places, here for example: How do you load custom UITableViewCells from Xib files?
Can anyone help me modify that for Cocoa on Mac?
Thanks,
David
Like this!
- (NSInteger)numberOfRowsInTableView:(NSTableView *)aTableView {
return count;
}
- (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row {
NSView *customView = [tableView makeViewWithIdentifier:#"customview"
owner:self];
…… // set properties
return customView;
}
In interface builder, set the identifier of your custom cell view to "customview" and it will automagically be created! Example:
Just replace "Automatic" with the identifier you are using
