我有代码工作，允许用户在按下标准编辑按钮时编辑表格中的某些项目（包括删除和插入新项目）。
这一切都按预期工作（我可以通过滑动删除，并且当按下＃34;编辑＆＃34;时会出现添加按钮），除非即使我在该按下时没有显示红色/绿色圆圈正确的编辑风格模式。
以下是我的表编辑代码：
- (void)viewDidLoad
{
[super viewDidLoad];
tableData = ptrBookmarks;
numberOfSections = 1; // for editing: initial number of sections
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
self.navigationItem.rightBarButtonItem = self.editButtonItem;
//allow row selection during editing.
//if the "Add Row" row is selected we can trigger an insert.
//rather than forcing the using to click the (+) icon directly
self.aTableView.allowsSelectionDuringEditing = YES;
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
if ([self isEditing]) // the current view is in editing mode, return count + an extra row
return [tableData count] + 1;
else // return count
return [tableData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
if(cell == nil){
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"];
}
//if number of rows is greater than the total number of rows in the data set
//and this view is in editing mode.
//Initialize the cell for "Add Row"
//there will be an extra row once SetEditing: is called
if(indexPath.row >= ptrBookmarks1.count && [self isEditing]){
cell.textLabel.text = @"Add Row";
}
else {
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
}
return cell;
}
//VIEW CONTROLLER METHOD: IMPORTANT
//this is a method of the view controller
//if we use apple's editing button as follows:
//self.navigationItem.rightBarButtonItem = self.editButtonItem
//then this method will be called automatically for us.
//if we are using a button callback or similar method,
//then we need to call setEditing: manually on the view
-(void) setEditing:(BOOL)editing animated:(BOOL)animated{
//wrap our code in an if statement
//only run the code if we are not swipe deleting a row.
//if we were called due to a swipeDelete action, ignore it
if(isSwipeDeleting == NO){
//call parent
[super setEditing:editing animated:animated];
//if editing mode
if(editing){
//batch the table view changes so that everything happens at once
[self.aTableView beginUpdates];
//for each section, insert a row at the end of the table
for(int i = 0; i < numberOfSections; i++){
//create an index path for the new row

//insert the NSIndexPath to create a new row. NOTE: this method takes an array of paths

修正了问题。我必须将Options +FollowSymLinks -MultiViews -Indexes
irectoryIndex index.php index.html index.htm
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([a-zA-Z0-9-/]+)/?$ /post.php?id=$1 [L]
添加到[aTableView setEditing:editing];函数，因为我使用的是UIViewController而不是UITableViewController。
