Question

我设法将以下数据（乘以数百）导出到NSDictionary中。我现在需要构建一种方法将这些数据放入Tinder风格的应用程序中。任何人都可以建议我如何让我的应用程序针对各种索引针对密钥“标题”提取数据。目前，它提取了45条包含该标题的数据记录，因为我的数据集中有45个密钥。

你应该有一系列字典正确吗？

若是，这应该有效：

NSInteger index = 0; //You can set this to the current page of your scroll view
NSArray * items = /* YOUR ARRAY OF DICTIONARIES */;
NSDictionary * dict = [items objectAtIndex:index];
NSString * title = [dict objectForKey:@"Title"];

您可能还考虑创建NSObject的子类并在字典的解析器中构建，以便您可以访问具有强类型的变量。
