我有一个tableview
,我填充JSON
,但它的价值是我的两倍。我只有2个对象,但它在tableview
中放了4个。有人可以告诉我我做错了什么以及为什么我只有2个时列出4个对象?我检查了计数和数据模型,它们都只显示了两个项目。
这是我的代码:

答案 0 :(得分:1)
我相信这就是为什么......
- (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;
}
将其改为此。
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
您正在为rootList中的每个对象添加一个部分,然后在每个部分中添加所有rootlist。所以只返回一个部分是最简单的。
