问题: 新建一个tableview,在设置数据源时,如果不retain一下数组的话,就会崩溃: array = [NSArray arrayWithObjects: @"1",@"2",@"3",@"4",@"5", nil]; [array retain]; 报错信息: -[NSCFString objectAtIndex:]: unrecognized selector sent to instance 0x4b436d0 新建tableview最精简的代码: - (void)viewDidLoad { [super viewDidLoad]; UITableView *tableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; tableView.delegate = self; tableView.dataSource = self; array = [NSArray arrayWithObjects: @"1",@"2",@"3",@"4",@"5", nil]; [array retain]; self.view = tableView; [tableView release]; }
