How can I adjust a UITableViewCell so that it would show two fields after swiping it left - identical to how the mail client does it?
Right now I only see the "Delete" button.
I would like to have the "More" field included there, too...
Also, for the first if clause Cell I do not get a "Insert" field.
- (UITableViewCellEditingStyle)tableView:(UITableView *)aTableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
if(indexPath.row == self.reports.count){
return UITableViewCellEditingStyleInsert;
} else {
return UITableViewCellEditingStyleDelete;
}
}
Is there a way to combine the fields with the | operator or something?
Thanks, EL-
You can use undocumented delegate methods for UITableView in iOS7
- (NSString *)tableView:(UITableView *)tableView titleForSwipeAccessoryButtonForRowAtIndexPath:(NSIndexPath *)indexPath
{
return #"More";
}
- (void)tableView:(UITableView *)tableView swipeAccessoryButtonPushedForRowAtIndexPath:(NSIndexPath *)indexPath
{
[self setEditing:NO animated:YES];
}
It seems that they are not private and can be submitted to appStore.

EDIT
My constraints on custom cells are all weird. Please disregard. Just using standard Left Detail ones now.
I don't understand why in iOS8 now my static table view cell contents are collapsing into the header of each section.
There's really almost nothing in my SettingsTVC.m. This is a just a test with all static data in the storyboard:
- (void)viewDidLoad {
[super viewDidLoad];
}
Have you implemented TableView delegate methods properly i.e
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
if(section == CUSTOM_SECTION)
{
return CUSTOM_VALUE;
}
return UITableViewAutomaticDimension;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return height;
}
I have a UITableView in the iPad xib file.
The delegate method:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
is correctly invoked.
But stil when I touch a row, or I swipe on it to delete it nothing happens.
In the xib file "User Interaction Enabled" for the table is on.
Thanks
UPDATE:
I've added this to the delegate, but still nothing:
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
return UITableViewCellEditingStyleDelete;
}
Have you implemented these methods :
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath*)indexPath {
return UITableViewCellEditingStyleDelete;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
}
This method tells if the table can be edited.
To go into edit mode, call [setEditing:YES animated:animated].
If you have setup a editButtonItem, it will do it for you when pressed.
In my storyboard, I have a UITableView and it has the following Properties
Style: Grouped
Content: Dynamic Prototypes
My question was how to make the different groups. When I run the app right now, there is no white backing (Only the default lined backing) with the text placed on top. Also, if I then created these dynamic groups, how would I set their header and footer?
Thanks
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 2;
}
-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
// implement your code
}
-(NSString *)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section{
//implement your code
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
/// Write basic code//
switch (indexPath.section) {
case 0:
//It belongs to first group and implement your code.
break;
case 1:
//It belongs to second group and implement your code.
break;
}
I think it will be helpful to you
I have a table, and I noticed that when I do the "swipe to delete", the red button is animated only the first time, the return (if I do another swipe) disappears without animation. These are the methods I use for this step:
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView
editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
return UITableViewCellEditingStyleDelete;
}
- (void)tableView:(UITableView *)tableView
commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath {
...
}
- (void)tableView:(UITableView *)tableView
didEndEditingRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView reloadData];
}
I forgot something to animate the return?
Thanks a lot!
Yeah, leave out the [tableView reloadData];. You only need to reload the table in -tableView:commitEditingStyle:etc:, and arguably not even then—it’s better to use the UITableView method -deleteRowsAtIndexPaths:withRowAnimation:. Reloading it is unnecessary and is why your delete button is disappearing instead of animating out.
Would you guyz be so kind to help me with such question:
I have to fill the tableView with cells and I also have an array with objects to fill cells with.
The question is - how to skip creating a cell if the object doesn't meet some conditions? I mean how to write something like:
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if(objectIsOk) {
//create cell
}
else {
//do nothing
}
return cell;
NOTE: I don't have an access to that array of objects it gives me an object per indexPath.row dynamically
I'm unsure as to what you mean by "skip creating a cell". Your table view data source is required to return a cell for each cellForRowAtIndexPath: call, which will get called for each row in each section that you have said the table will contain.
If you want to return a blank cell then why not just do something like this:
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;
if (objectIsOk) {
// Create normal cell
} else {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"BlankCell"];
}
return cell;
}
You could also return height of zero in the heightForRowAtIndexPath: delegate method to make it appear that it's not there, like so:
- (CGFloat)tableView:(UITableView *)aTableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (objectIsOk) {
return 44.0f;
} else {
return 0.0f;
}
}
