大佬教程收集整理的这篇文章主要介绍了ios – Assertion failure in – [UITableView _configureCellForDisplay：forIndexPath：]，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

有人可以告诉我为什么我得到这个错误？

这是我的.m文件：

#import "ListaParticipantesViewController.h"
#import "Participantes.h"
#import "ModParticipantesViewController.h"

@implementation ListaParticipantesViewController

@synthesize dao;
@synthesize participantes;

- (void)viewDidLoad
{
    dao = [[ParticipantesDAO alloc] init];
    participantes = [[NSMutableArray alloc] init];
    participantes = [dao getDatos];
    [super viewDidLoad];

}

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

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [participantes count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowATindexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"celda";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    cell.textLabel.text = [[participantes objectATindex:[indexPath row]] valueForKey:@"nombre"];

    return cell;
}

#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSELEctRowATindexPath:(NSIndexPath *)indexPath
{

    ModParticipantesViewController *desTino = [self.storyboard instantiateViewControllerWithIdentifier:@"visualizacion"];
    Participantes *tmp = [participantes objectATindex:[indexPath row]];
    desTino.participante = tmp;

    [self.navigationController pushViewController:desTino animated:YES];
}

@end

显示的错误是：
