我想在我的表视图中显示一个位于parse.com上的数据库中的数组 我可以显示数组中的第一项,但不显示其余项。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell==nil){
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
_ListArray = [object objectForKey:@"content"];
NSLog(@"OBJECT = %@",_ListArray);
NSString *cellValue = [NSString stringWithFormat:@"%@", [_ListArray objectAtIndex:indexPath.row]];
cell.textLabel.text = cellValue;
if(refresh <counter)
{
NSString *br = @"<br>";
List = [NSString stringWithFormat:@"%@%@%@", List, br, cell.textLabel.text];
NSLog(@"%@",List);
refresh ++;
}
cell.accessoryType =UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
如果我尝试使用:
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [_ListArray count];
}
表中我什么也没得到。
编辑更新:
删除了self.ListArray并使用_ListArray。
在h文件中:
NSMutableArray *ListArray;
...
@property (retain, atomic) NSMutableArray *ListArray;
然后在m文件中:
@synthesize ListArray = _ListArray;
关于:
self.ListArray = [object objectForKey:@"content"];
对象是PFObject。
我有queryForTable,我从解析中获取数据。
- (PFQuery *)queryForTable {
PFQuery *query = [PFQuery queryWithClassName:@"List"];
[query whereKey:@"user" equalTo:[PFUser currentUser]]; // user
[query whereKey:@"objectId" equalTo:[theListID objectId]]; // the specific list
counter =[query countObjects];
NSLog(@"%d",counter);
// If Pull To Refresh is enabled, query against the network by default.
if (self.pullToRefreshEnabled) {
query.cachePolicy = kPFCachePolicyNetworkOnly;
}
// 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 orderByDescending:@"createdAt"];
return query;
}
到objectForKey:@“content”]; content是我的类在解析时的列的名称 所以我需要说出我想要的类中的哪个对象,那就是名为“content”的数组列

答案 0 :(得分:1)
得到它的工作,确实把数组从解析中获取数据,然后只调用
cell.textLabel.text = [_ListArray objectAtIndex:indexPath.row];
然后我可以使用:
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [_ListArray count];
}
