TableView中的更多单元格

Question

我有一个tableview，我使用的是JSON，但它使我拥有的值翻倍。我只有2个对象，但它在tableview中放4个。有人可以告诉我我做错了什么，以及为什么当只有2个时列出4个对象？我检查了计数和数据模型，它们都只显示2个项目。

这里是我的代码：

我相信这是为什么...

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
{ 
rootList =[[GlobalData sharedData].mRootBeers getRootBeers]; 
NSLog(@"RootList: %@", rootList); 
// Return the number of sections. 
NSLog(@"RootList count: %i", rootList.count); 
return rootList.count; 
} 

改变它这一点。

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

要添加部分在rootList每个对象，然后将所有rootlist的每个部分。所以只返回一个部分是最简单的。
