Question

我的项目中有一个问题，在tableview中显示结果。我在NSmutableArray＆＃34; ActosPueblo＆＃34;并且uitableview正确地打印了这个结果，但是当行中点击时出现错误＆＃34; NSArrayM objectatin索引1超出界限[0..0]＆＃34;或者只是显示来自不同行的详细信息，而不是点击的行。

我在.m中的代码是......

- (void)viewDidLoad{

[super viewDidLoad];
NSString *titulo = [NSString stringWithFormat:@"%@ %@, %@", tipoNombreDia, tipoNumeroDia, tempNombreMes];
self.title = titulo;

//loading antes de pedir los datos
[SVProgressHUD showWithStatus:@"Cargando..." maskType:SVProgressHUDMaskTypeBlack];

[self cargarActosPueblos];


}


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{

return [actosPueblo count];
}


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

NSDictionary *dictionary =[actosPueblo objectAtIndex:section];
NSArray *array = [dictionary objectForKey:@"ActosPueblo"];

return [array count];
}

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

CalendarioActosViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];


NSDictionary *dic = [actosPueblo objectAtIndex:indexPath.section];

NSArray *array = [dic objectForKey:@"ActosPueblo"];

NSString *tipoEvento = [[array objectAtIndex:indexPath.row] objectForKey:@"TipoEventos"];
cell.labelEvento.text = tipoEvento;

NSString *tipoMunicipio = [[array objectAtIndex:indexPath.row] objectForKey:@"Municipio"];
cell.labelMunicipio.text = tipoMunicipio;

NSString *tipoGanaderia = [[array objectAtIndex:indexPath.row] objectForKey:@"Ganaderias"];
cell.labelGanaderia.text = tipoGanaderia;

NSString *tipoFecha = [[array objectAtIndex:indexPath.row] objectForKey:@"Fecha"];
cell.labelFecha.text = tipoFecha;

NSString *tipoHora = [[array objectAtIndex:indexPath.row] objectForKey:@"Hora"];
cell.labelHora.text = tipoHora;

NSString *indexP = [NSString stringWithFormat:@"fila: %ld", (long)indexPath.row];
cell.index.text = indexP;

NSString *urlImagen = [[array objectAtIndex:indexPath.row] objectForKey:@"ImagenEvento"];
//precarga imagen con SDWebImage
//precarga imagen con SDWebImage
if([urlImagen length] == 0){
    cell.celdaThumb.image = [UIImage imageNamed:@"sin-icono.png"];
}else{
    [cell.celdaThumb setImageWithURL:[NSURL URLWithString:urlImagen] placeholderImage:[UIImage imageNamed:@"sin-icono.png"]];
}


actos = [[NSMutableArray alloc] init];

for (NSDictionary* dic in array) {

    CalendarioActos *actPob = [[CalendarioActos alloc] init];

    actPob.apGanaderia= [dic objectForKey:@"Ganaderias"];
    actPob.apEvento = [dic objectForKey:@"TipoEventos"];
    actPob.apFecha = [dic objectForKey:@"Fecha"];
    actPob.apHora = [dic objectForKey:@"Hora"];
    actPob.apMunicipio = [dic objectForKey:@"Municipio"];
    actPob.apProvincia = [dic objectForKey:@"Provincia"];
    actPob.apToroImagen = [dic objectForKey:@"Imagen"];

    [actos addObject:actPob];

}

return cell;
}


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if([self.checkedIndexPath isEqual:indexPath]){
    self.checkedIndexPath = nil;
}else{
    self.checkedIndexPath = indexPath;
}

CalendarioActosViewCell *cell =(CalendarioActosViewCell*) [tableView cellForRowAtIndexPath:indexPath];
[self performSegueWithIdentifier:@"actoTodiaActo" sender:cell];
}

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{

if([segue.identifier isEqualToString:@"actoTodiaActo"]){
    CalendarioActosDetallesViewController *detallesController= (CalendarioActosDetallesViewController *)segue.destinationViewController;
    NSIndexPath *indexPath = [self.tableViewAP indexPathForSelectedRow];


        cal = [actos objectAtIndex:indexPath.row];

   /* NSString *index = [NSString stringWithFormat:@"%lu", [actos count]];
    //alerta campo vacío
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Count Actos" message:index delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    // Mostrar alerta
    [alert show];*/


    detallesController.tempEvento = cal.apEvento;
    detallesController.tempFecha = cal.apFecha;
    detallesController.tempGanaderia = cal.apGanaderia;
    detallesController.tempHora = cal.apHora;
    detallesController.tempImagen = cal.apToroImagen;
    detallesController.tempMunicipio = cal.apMunicipio;
    detallesController.tempProvincia = cal.apProvincia;


    NSString *datos = [NSString stringWithFormat:@"%@ %@ %@ %@ %@ %@ %@", cal.apEvento, cal.apFecha, cal.apGanaderia, cal.apHora, cal.apMunicipio, cal.apProvincia, cal.apToroImagen];
    NSLog(@"pasamos: %@", datos);


}

}

＆＃34; ActosPueblo＆＃34;包含来自url的数据，来自函数＆＃34; cargarActosPueblos＆＃34;在viewload。

我在stackoverflow.com上看到了同样问题的其他问题，但对我没有任何结果。

请检查我的代码并接受任何建议。

谢谢和问候

Answer 1

每次致电cellForRowAtIndexPath时，您都会创建一个新数组actos。因此，它只会在其中有一个对象（位置0）。当你试图为0以外的任何一行访问它时，那就是你的崩溃。

我建议您在使用索引路径引用某些内容时使用相同的数据结构，而不是尝试创建不是ActosPueblo的第二个数组。

我不确定你在didSelectRowAtIndexPath想要实现的目标是你真正需要做的就是执行segue，因为你将获得prepareForSegue中的选定项目：

- (void)tableView:(UITableView *)tableView 
                               didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
   [self performSegueWithIdentifier:@"actoTodiaActo" sender:self];
}

“NSArrayM objectatin索引1超出界限[0..0]”

表示您正在访问大于数组大小的元素。

<强>的cellForRowAtIndexPath

- (UITableViewCell *)tableView:(UITableView *)tableView 
                        cellForRowAtIndexPath:(NSIndexPath *)indexPath{
//Get the tipo at this index
NSDictionary *dic = [actosPueblo objectAtIndex:indexPath.section];
NSArray *array = [dic objectForKey:@"ActosPueblo"];
NSDictionary *tipo  = [array objectAtIndex:indexPath.row];

//Configure the cell
static NSString *CellIdentifier = @"Cell";
CalendarioActosViewCell*cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier 
                                                                forIndexPath:indexPath];
cell.labelEvento.text = tipo[@"TipoEventos"];
cell.labelMunicipio.text = tipo[@"Municipio"];
cell.labelGanaderia.text = tipo[@"Ganaderias"];
cell.labelFecha.text = tipo[@"Fecha"];
cell.labelHora.text = tipo[@"Hora"];
cell.index.text = [NSString stringWithFormat:@"fila: %ld", (long)indexPath.row];
NSString *urlImagen = tipo[@"ImagenEvento"];

if([urlImagen length] == 0){
    cell.celdaThumb.image = [UIImage imageNamed:@"sin-icono.png"];
}else{
    [cell.celdaThumb setImageWithURL:[NSURL URLWithString:urlImagen] 
                         placeholderImage:[UIImage imageNamed:@"sin-icono.png"]];
}


return cell;
}

<强> didSelectRowAtIndexPath方法

- (void)tableView:(UITableView *)tableView 
                didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    [self performSegueWithIdentifier:@"actoTodiaActo" sender:self];
}

<强> prepareForSegue

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{

if([segue.identifier isEqualToString:@"actoTodiaActo"]){

    //Get the Selected tipo at this index
    NSIndexPath *indexPath = [self.tableViewAP indexPathForSelectedRow];
    NSDictionary *dic = [actosPueblo objectAtIndex:indexPath.section];
    NSArray *array = [dic objectForKey:@"ActosPueblo"];
    NSDictionary *tipo  = [array objectAtIndex:indexPath.row];

    CalendarioActosDetallesViewController *detallesController = 
       (CalendarioActosDetallesViewController *)segue.destinationViewController;      

    detallesController.tempEvento = tipo[@"TipoEventos"];
    detallesController.tempFecha = tipo[@"Fecha"];
    detallesController.tempGanaderia = tipo[@"Ganaderias"];
    detallesController.tempHora = tipo[@"Hora"];
    detallesController.tempImagen = tipo[@"ImagenEvento"];
    detallesController.tempMunicipio = tipo[@"Municipio"];
    detallesController.tempProvincia = tipo[@"Provincia"];

    //log
    NSString *datos = [NSString stringWithFormat:@"%@ %@ %@ %@ %@ %@ %@",
                    cal.apEvento, cal.apFecha, cal.apGanaderia, cal.apHora, 
                    cal.apMunicipio, cal.apProvincia, cal.apToroImagen];
    NSLog(@"pasamos: %@", datos);
}

}
