使用Parse WITHOUT刷新tableview滑动以删除UITableview中的单元格

Question

目前，我可以删除要滑动删除的表格视图单元格。但是，只有刷新UITableView后，才会对单元格删除进行动画处理。我希望删除单元格，因为我在刷卡删除后按下红色删除按钮，而不是每次删除单元格时都要刷新它。这是我的参考代码：

- (id)initWithCoder:(NSCoder *)aCoder
{
self = [super initWithCoder:aCoder];
if (self) {
    // Custom the table

    // The className to query on
    self.parseClassName = @"fgrep";

    // The key of the PFObject to display in the label of the default cell style
    self.textKey = @"name";

    // Whether the built-in pull-to-refresh is enabled
    self.pullToRefreshEnabled = YES;

    // Whether the built-in pagination is enabled
    self.paginationEnabled = NO;

    // The number of objects to show per page
    //self.objectsPerPage = 10;
 }
 return self;
 }

 - (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(refreshTable:)
                                             name:@"refreshTable"
                                           object:nil];

 }
 - (void)refreshTable:(NSNotification *) notification
 {
// Reload the recipes
[self loadObjects];
 }


 - (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
 }
 - (void)viewDidUnload
 {
[super viewDidUnload];
// Release any retained subviews of the main view.
[[NSNotificationCenter defaultCenter] removeObserver:self name:@"refreshTable" object:nil];
 }

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
 {
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
 }

 - (PFQuery *)queryForTable

 {
PFQuery *fgquery = [PFQuery queryWithClassName:@"fgrep"];
[fgquery whereKey:@"user" equalTo:[PFUser currentUser]];


// If no objects are loaded in memory, we look to the cache first to fill the table
// and then subsequently do a query against the network.
/*    if ([self.objects count] == 0) {
 query.cachePolicy = kPFCachePolicyCacheThenNetwork;
 }*/

//    [query orderByAscending:@"name"];

return fgquery;
 }
 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object
 {
static NSString *simpleTableIdentifier = @"FGRepCell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}

// Configure the cell

UILabel *nameLabel = (UILabel*) [cell viewWithTag:101];
nameLabel.text = [object objectForKey:@"name" ];

UILabel *operationtime = (UILabel*) [cell viewWithTag:102];
operationtime.text = [object objectForKey:@"fgoperation"];

UILabel *yards = (UILabel*) [cell viewWithTag:103];
yards.text = [object objectForKey:@"fgyards"];

UILabel *hashe = (UILabel*) [cell viewWithTag:104];
hashe.text = [object objectForKey:@"fghash"];

UILabel *makeormiss = (UILabel*) [cell viewWithTag:105];
makeormiss.text = [object objectForKey:@"fgmakeormiss"];

return cell;
 }
 - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{
return YES;
 }


 - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath 
 {    if (editingStyle == UITableViewCellEditingStyleDelete) {


// Remove the row from data model
PFObject *objectToDel = [self.objects objectAtIndex:indexPath.row];

[objectToDel deleteInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {

    [self loadView];
}
 ];
 }}

 - (void) objectsDidLoad:(NSError *)error
 {
[super objectsDidLoad:error];

NSLog(@"error: %@", [error localizedDescription]);
 }





 @end

我认为我的主要问题与此代码段有关：

 - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath 
 {    if (editingStyle == UITableViewCellEditingStyleDelete) {


// Remove the row from data model
PFObject *objectToDel = [self.objects objectAtIndex:indexPath.row];

[objectToDel deleteInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {

    [self loadView];
}
 ];
 }}

再一次，我可以在滑动并按下红色删除按钮后从表格视图中删除单元格，但只有在刷新表格视图后才能删除单元格。一旦按下刷过单元格后显示的红色删除按钮，我想删除单元格。

您需要：

而不是重新加载tableview

1. 从本地数据源删除对象
2. 在您的tableView
上致电beginUpdates，deleteRowsAtIndexPaths:withRowAnimation:和endUpdates
