UITableViewController não está carregando dados
Então eu criei uma subclasse deUITableViewController
e defina o delegado e a origem de dados para si mesmo. Mas ainda os métodos comocellForRowAtIndexPath
enumberOfRowsInSection
nunca ser chamado.numberOfSectionsInTableView
retorne 1 toda vez. É assim que o viewDidLoad () se parece
- (void)viewDidLoad {
[super viewDidLoad];
NSMutableArray* list = [[NSMutableArray alloc] init];
self.tableView = [[UITableView alloc] init];
self.tableView.delegate = self;
self.tableView.dataSource = self;
self.actionList = list;
self.clearsSelectionOnViewWillAppear = NO;
self.contentSizeForViewInPopover = CGSizeMake(320.0, 400.0);
[self.actionList addObject:@"t1"];
[self.actionList addObject:@"t2"];
}
Quando tento carregar isso em um popover, tudo que consigo é um popover em branco.
Eu passei muito tempo nisso. Por favor, me ajude.
