根据按钮单击字母或数字顺序对UITableView进行排序

我已经为四个标签定制了uitableview单元格，并且还为每个标签保存了数据。 label1包含对象的名称，标签2包含价格标签3，标签4包含其他数据。现在有两个按钮，第一个按钮点击我想按照对象名称的字母顺序对表格进行排序，第二个按钮点击我想根据价格排序..请指导我如何做到这一点..这是我的代码。。根据按钮单击字母或数字顺序对UITableView进行排序

if(btn.tag == 500) 
{ 
    aSortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"OrderDate" ascending:YES]; 
} 
if(btn.tag == 501) 
{ 
    aSortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"CustomerGuid" ascending:YES];  
} 
if (searching) { 
    [temp_details sortUsingDescriptors:[NSArray arrayWithObject:aSortDescriptor]]; 
} 
else{ 
    [orders sortUsingDescriptors:[NSArray arrayWithObject:aSortDescriptor]]; 
} 
[self.tableView reloadData];

@克里希纳..什么是initwithkey意味着排序字符串：我已阅读文档，但不明白..请你详细说明一下。谢谢 – NoviceDeveloper 2012-02-15 06:01:20

那些字典里面的关键字，我将它设置到tableview标签中，这样排序字典，我重新载入表格 – 2012-02-15 06:13:08

所以我必须在我的应用中使用字典吗？我还没有使用任何字典。 – NoviceDeveloper 2012-02-15 06:18:48

你可以看到关于以下方法的NSArray类的引用。

排序

sortedArrayHint 
sortedArrayUsingFunction:context: 
sortedArrayUsingFunction:context:hint: 
sortedArrayUsingDescriptors: 
sortedArrayUsingSelector: 
sortedArrayUsingComparator: 
sortedArrayWithOptions:usingComparator:

至于你的问题，你可以通过

[strings sortedArrayUsingSelector:@selector(compare:)]
