ios - UITableView 中的 NSDictionary - 使用索引路径

Question

我正在尝试使用 NSDictionary 中的数据填充我的 UITable View 。如果我能够像 cellForRowAtIndexPath 中给出的那样使用 indexPath 访问数据，那就太好了。

{
"December 2012" =     (
    "2012-12-08 13:56:53 +0000"
);
"July 2013" =     (
    "2013-07-17 12:54:22 +0000"
);
"June 2013" =     (
    "2013-06-17 12:29:57 +0000",
    "2013-06-20 12:02:17 +0000",
    "2013-06-21 11:55:58 +0000",
    "2013-06-21 12:16:59 +0000",
    "2013-06-25 12:59:39 +0000",
    "2013-06-25 13:01:10 +0000",
    "2013-06-25 13:02:22 +0000",
    "2013-06-26 12:24:28 +0000",
    "2013-06-27 12:29:00 +0000"
);
"May 2013" =     (
    "2013-05-23 12:54:35 +0000"
);

2013-06-28 08:49:49.948 [4714:c07] <NSIndexPath 0x747b840> 2 indexes [0, 0]
2013-06-28 08:49:49.950 [4714:c07] <NSIndexPath 0x8563750> 2 indexes [1, 0]

2013-06-28 08:49:49.954 [4714:c07] <NSIndexPath 0x7489550> 2 indexes [2, 3]
2013-06-28 08:49:49.955 [4714:c07] <NSIndexPath 0x818ddc0> 2 indexes [2, 4]
2013-06-28 08:50:10.298 [4714:c07] <NSIndexPath 0x955f6c0> 2 indexes [2, 5]
2013-06-28 08:50:10.330 [4714:c07] <NSIndexPath 0x8360750> 2 indexes [2, 6]
2013-06-28 08:50:10.346 [4714:c07] <NSIndexPath 0x85739e0> 2 indexes [2, 7]
2013-06-28 08:50:10.363 [4714:c07] <NSIndexPath 0x9560690> 2 indexes [2, 8]
2013-06-28 08:50:10.380 [4714:c07] <NSIndexPath 0x9065b00> 2 indexes [3, 0]
2013-06-28 08:50:10.998 [4714:c07] <NSIndexPath 0x9660f70> 2 indexes [2, 2]

上面你会看到我的字典的布局，下面是相应的索引路径。我获取数据的最佳方法是什么？我应该使用 NSDictionary 以外的东西吗？

Answer 1

就像@wain 和@pgd 说的。取一个可变数组，然后添加从字典中获取的每个数组。

例如:

  displayArray = [[NSMutableArray alloc]init]; // 

  NSArray *keys = [MyDict allKeys];  // Getting all key from you dictionary

  for (id key in MyDict) {
    NSArray *anArray = [dict objectForKey:key];

    [displayArray addObject:anArray]
}

显示时使用节号获取数组。

   NSArray * array = [displayArray  objectAtIndex:indexPath.section]

希望这会有所帮助。
