[英]Tableview not showing all of PFQuery results
I'm seeing some unexpected behavior in my tableview and I'm hoping someone can help point it out. 我在表视图中看到一些意外的行为,希望有人可以帮助指出。 I have 63 records in a Parse database called ShowContacts. 我在名为ShowContacts的解析数据库中有63条记录。 However, my tableview is displaying records 1-13 three consecutive times. 但是,我的表视图连续3次显示记录1-13。 NSLog shows that all 63 are in my "items" array but they are not all being displayed in my tableview. NSLog显示所有63个都在我的“项目”数组中,但是它们并没有全部显示在我的表视图中。 What am I missing? 我想念什么?
Thanks in advance, Darin 预先感谢,达林

@interface ShowContactsViewController ()
@property (strong,nonatomic) NSMutableArray *items;
@end
- (void)viewDidLoad
{
[PFQuery clearAllCachedResults];
PFQuery *query = [PFQuery queryWithClassName:@"ShowContacts"];
query.cachePolicy = kPFCachePolicyIgnoreCache;
[query orderByAscending:@"Name"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
NSMutableArray *items = [NSMutableArray array];
for (id obj in objects)
{
[items addObject:obj];
}
self.items = items;
NSLog(@"%@", objects);
NSLog(@"%lu", (unsigned long)[objects count]); // 63 records according to NSLog
[self.myTableView reloadData];
} else {
// Log details of the failure
NSLog(@"Error: %@ %@", error, [error userInfo]);
}
}];
}
}
#pragma mark Table
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return self.items.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (nil == cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
cell.textLabel.text = [[self.items objectAtIndex:indexPath.row] objectForKey:@"Name"];
}
return cell;
}
Change - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
to 更改- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
到
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (nil == cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
}
cell.textLabel.text = [[self.items objectAtIndex:indexPath.row] objectForKey:@"Name"];
return cell;
}
