我的NSMutableArray名为records，NSArray。
现在，我正在使用TBXML parser检索XML属性及其值，并在NSArray中插入属性值。
此NSArray是records的对象。
当我想在tableview单元格中显示XML数据的值时，numerberOfRowsInSection会是什么？
这是我的数据检索程序......
[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....
<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>
我能够在UITableviewCell中检索数据，但它显示NSArray的前两个检索数据，因为records数组中的行数为2。但我想根据NSArray检索的属性值总数设置numberOfRowsInsection。
我遇到了问题，我知道问题在这里：
- (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？

有两种方法可以解决这个问题。
正确的方法是查看有关解析的this TBXML tutorial。这将向您展示如何解析每个ProductData元素条目中的每个属性。
蛮力方法（我不会这样做）将解析你的“记录”数组，如下所示：
@"<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>"
等等
for(NSString * elementText in records)
{
NSLog( @"%@", elementText );
// and search for "<" and ">" and strip out the name and the value using
// substring
}
