¿Cuál será el tipo de retorno de INSCERTURA NumberOfROWROWROWROWS para UITableView cuando se recuperan los datos XML?

Question

1. tengo un NSMutableArray nombrado como records y un NSArray.

2. Ahora estoy recuperando un atributo XML y su valor, usando TBXML parser e insertar el valor del atributo en el NSArray.

3. Este NSArray es un objeto de records.

Que sera el numerberOfRowsInSection ¿Cuándo quiero mostrar el valor de los datos XML en la celda TableView?

Este es mi procedimiento de recuperación de datos ...

[records addObject:[NSArray arrayWithObjects:
    [TBXML textForElement:id],
    [TBXML textForElement:productNumber],
    [TBXML textForElement:name],
    [TBXML textForElement:availableStock],
    [TBXML textForElement:image],
    [TBXML textForElement:quantityOrderMin],
    [TBXML textForElement:dateCreated],
    [TBXML textForElement:dateUpdated],nil]];

Y mis datos XML son ...

<ProductData HASH="21106941">
    <id>1</id>
    <productNumber>a91cc0f4c7</productNumber>
    <name>Product 1</name>
    <seoTitle>product-1</seoTitle>
    <viewCount>0</viewCount>
    <availableStock>100.0</availableStock>
    <lowStock>0.0</lowStock>
    <image>5e928bbae358c93caedf6115fa7d178b.jpg</image>
    <quantityOrderMax>20.0</quantityOrderMax>
    <dateCreated>2011-10-06T16:08:45</dateCreated>
</ProductData>
<ProductData HASH="409555632">
    <id>2</id>
    <productNumber>d8287e2e51</productNumber>
    <name>Product 2</name>
    <seoTitle>product-2</seoTitle>
    <description>
    <p>Lorem ipsum dolor sit amet, consectetue...</p>
    </description>
    <viewCount>0</viewCount>
    <availableStock>100.0</availableStock>
    <image>8bbd8dfff3cdd28285d07810a4fe7c32.jpg</image>
    <quantityOrderMin>1.0</quantityOrderMin>
    <dateCreated>2011-10-06T16:08:45</dateCreated>
</ProductData>

Puedo recuperar datos en UITableviewCell, pero está mostrando los dos primeros datos recuperados del NSArray Porque el número de filas es dos en records formación. Pero quiero establecer el número de INSECCIÓN NumberOfRowS de según el número total de valor de atributo recuperado por NSArray.

Tengo el problema y sé que el problema está aquí:

  - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
        NSLog(@"The number of row in the object array:  %d ",[records count]);
        return [records count];
    }

¿Cómo puedo arreglarlo?

Answer 2

Hay dos formas de abordar este problema.

1. La forma correcta sería echar un vistazo a Este tutorial tbxml con respecto al análisis. Esto muestra qué hacer para analizar cada uno de los atributos de cada uno ProductData entrada de elemento.

2. El método de la fuerza bruta (que no es que haría) sería analizar su matriz de "registros", que se ve así:

   @"<id>1</id>",@"<productNumber>a91cc0f4c7</productNumber>",@"<name>Product 1</name>",@"<seoTitle>product-1</seoTitle>",@"<viewCount>0</viewCount>",
   @"<availableStock>100.0</availableStock>",@"<lowStock>0.0</lowStock>",@"<image>5e928bbae358c93caedf6115fa7d178b.jpg</image>",
   @"<basePrice>10.0</basePrice>",@"<costPrice>0.0</costPrice>",@"<height>1.0</height>",@"<width>1.0</width>",@"<depth>1.0</depth>",@"<weight>2.0</weight>"
   

   y así sucesivamente a través de esta enumeración rápida

   for(NSString * elementText in records)
   {
       NSLog( @"%@", elementText );
       // and search for "<" and ">" and strip out the name and the value using
       // substring
   }
