I have a UIViewController class, with a tableView. In viewDidLoad:
UIBarButtonItem *editIcon = [[[UIBarButtonItem alloc]
initWithBarButtonSystemItem: UIBarButtonSystemItemEdit
target:self
action:@selector(toggleEditMode)] autorelease];
In te method 'toggleEditMode':
-(void)toggleEditMode{
if(self.theTable.editing) {
[theTable setEditing:NO animated:YES];
[self.navigationItem.rightBarButtonItem setStyle:UIBarButtonItemStylePlain];
}
else if ([callsArray count]!=0){
[theTable setEditing:YES animated:YES];
[self.navigationItem.rightBarButtonItem setStyle:UIBarButtonItemStyleDone];
}
}
The problem is that the Edit button does not change do 'DONE'. What's missing? I have all the methods declared:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
Thanks,

Why not use -editButtonItem
of UIViewController directly ? And override -setEditing:animated:
method.
// Assign the system's edit button,
// it will change style when different edit status.
self.navigationItem.rightBarButtonItem = self.editButtonItem;
// The editButtonItem will invoke this method.
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
[super setEditing:editing animated:animated];
if (editing) {
// Execute tasks for editing status
} else {
// Execute tasks for non-editing status.
}
}
It's because you're only setting the style of the button (not its text) when you switch modes. You need to do this (or equivalent):
-(void)toggleEditMode{
self.navigationItem.rightBarButtonItem.title = self.tableView.editing ? @"Done" : @"Edit";
