如何在iOS的UITableVIew中显示解析的PFUser数组？

到目前为止，我已经尝试了以下代码：

PFGeoPoint * myGeoPoint = [PFUser currentUser][@"coordinates"]; // Your geoPoint
PFQuery *query = [PFUser query];
[query includeKey:@"User"];
[query whereKey:@"coordinates" nearGeoPoint:myGeoPoint withinMiles:radiusInMiles];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if(!error){
for (PFUser *object in objects){
            users = (NSArray*)[object ObjectForKey:@"User"];
        }
        [self.tableView reloadData];
    }

}     
    
}];
- (PFUser*) objectAtIndexPath:(NSIndexPath*)indexPath {
PFUser *object = [PFUser objectWithClassName: @"User"];
[object setObject:[users objectAtIndex:indexPath.row] forKey:@"User"];
return object;
}
// Use myObjects for numberOfRowsInSection:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:    (NSInteger)section {
return users.count;
}
//Use your custom object for cellForRowAtIndexPath:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath object:(PFUser *)object {
static NSString *simpleTableIdentifier = @"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

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

// Configure the cell using object
UILabel *reviewLabel = (UILabel *)[cell viewWithTag:10];
reviewLabel.text = [object objectForKey:object.username];
PFFile *userImageFile = object[@"profilePic"];
[userImageFile getDataInBackgroundWithBlock:^(NSData *imageData, NSError *error) {
    if (!error) {
        if (imageData != nil)
            cell.imageView.image = [UIImage imageWithData:imageData];
        else cell.imageView.image= [UIImage imageNamed:@"defaultPerson"];
    }
}];

}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
  {

  SMChatViewController *chatController = [SMChatViewController alloc];

// [chatController initWithPhoto:image];

    [self presentModalViewController:chatController animated:YES];

}

在这段代码中，我将PFUsers数组作为“objects”检索。当我将objects数组保存给用户时，它返回为空。那么，有谁能给我一些建议，我如何在tableView中设置用户名和profilepic

我猜这个查询是不正确的。 试试这个：

PFGeoPoint * myGeoPoint = [PFUser currentUser][@"coordinates"]; // Your geoPoint
PFQuery *query = [PFQuery queryWithObject:@"_User"];
NSArray *userList = [NSArray new];

[query whereKey:@"coordinates" nearGeoPoint:myGeoPoint withinMiles:radiusInMiles];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if(!error){
         userList = objects;
        [self.tableView reloadData];
    }

}];

在您的代码中，您询问“用户”对象，然后从该对象获取“用户”字段

你能在

findobjectsinbackgroundithblock

@VivekMolkar中记录并检查你是否收到了一个有效的数组

objects

。是的，我可以在“objects”中接收数组，但不能在“users”中加载它。你能给我看看

objects

@VivekMolkar中的值吗？请看问题，我用日志输出更新了它。只是检查一下，您使用

users=（NSArray*）[objectobjectforkey:@“User”]确保您使用的钥匙是正确的？因为刚才上传的图像u显示的是
用户
，但在代码中它是
用户
查询是正确的，但我无法将数组加载到tableView，您能帮我吗？您能帮我建议如何将数组加载到tableView吗？
- (UITableViewCell *)tableView:(UITableView *)tableView     cellForRowAtIndexPath:(NSIndexPath*)indexPath {

static NSString *simpleTableIdentifier = @"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

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

   PFUser *user = (PFUser*)[users objectAtIndex:indexPath.row];

cell.textLabel.text=user.username;

PFFile *userImageFile = user[@"profilePic"];
[userImageFile getDataInBackgroundWithBlock:^(NSData *imageData, NSError *error) {
    if (!error) {
if (imageData != nil)
            cell.imageView.image = [UIImage imageWithData:imageData];
        else cell.imageView.image= [UIImage imageNamed:@"defaultPerson.png"];
    }
}];
return cell;
}
