检索XML数据时，uitableview的numberOfRowsInSection返回类型是什么? [英] What will be the numberOfRowsInSection return type for uitableview when XML data is retrieved?

问题描述

1. 我有一个名为records的NSMutableArray和一个NSArray.

现在，我要使用TBXML parser检索XML属性及其值，并将属性值插入NSArray.

Now I am retrieving an XML attribute and its value, using TBXML parser and inserting the attribute value in the NSArray.

此NSArray是records的对象.

当我想在表视图单元格中显示XML数据的值时，numerberOfRowsInSection是什么?

What will be the numerberOfRowsInSection when I want to display the value of XML data in tableview cell?

这是我的数据检索过程....

This is my data retrieving procedure....

[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]];

我的XML数据是......

And my XML data are....

<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>

我能够检索UITableviewCell中的数据，但是它显示NSArray的前两个检索到的数据，因为records数组中的行数为2.但是我要设置numberOfRowsInsection将根据NSArray检索到的属性值的总数.

I am being able to retrieve data in UITableviewCell, but it's displaying first two retrieved data of the NSArray because the number of rows are two in records array. but i want to set the numberOfRowsInsection will be according to the total number of attribute value retrieved by NSArray.

我遇到了问题，我知道问题在这里:

I have got the problem and I know the problem is here:

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

我该如何解决?
