在viewController中重新加载tableView

Question

I have a viewcontroller set up on my storyboard, and I have inserted a tableView inside this view controller. I want to do a [self.tableView reloadData]; on viewDidLoad, but it says the property tableView isn't found.

Here is what the code for my tableView in the viewcontroller.m file looks like:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section     {
    return @"Shared with";
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return activeUsers.count;
}

- (sharedUsersTable *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"sharedUser";

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

    NSDictionary *key = [activeUsers objectAtIndex:indexPath.row];
    NSString *name = [key objectForKey:@"shared_user_name"];
    NSString *email = [key objectForKey:@"email"];

    cell.textLabel.text = [NSString stringWithFormat:@"%@", name];
    cell.detailTextLabel.text = [NSString stringWithFormat:@"%@", email];

    return cell;
}

Am I missing some special command to call a tableView inside a view controller which isn't a TableViewCOntroller?

Answer 1

你需要创建一个tableView的IBOutlet并在其上调用reloadData 。

This depends on how you declared your UITableView .

If it is a property ( @property (nonatomic, strong) UITableView *myTableView ), it will be [self.myTableView reloadData] . If you declared it as just an instance variable ( UITableView *_myTableView ), it will be [_myTableView reloadData] .

you'll have to define tableview datasource and delegate as self.. like table.datasource=self , and table.delegate=self .....you can do it in viewdidload....but if you have downloaded the data somewhere, then you can do it in that place where you have downloaded and reload the table there. please assign the delegate and datasource to the table and reload the tableview after you have downloaded the data....and please make a property like (@property (nonatomic, strong) UITableView *table) and use self when you do the reload...
