Question

我想按时间对数组进行排序。但问题是时间是在另一个数组（数组的子数组）中的Form UNIX时间戳中。

这是格式。请任何人帮我分类。

某些数组有时间戳，某些数组没有时间戳

这对我来说非常复杂。任何人都可以帮助我感谢

Answer 1

您需要指定一个自定义比较器块，如下所示（您需要根据数据结构调整索引）：

NSArray *array = @[@[@"a", @456], @[@"b", @123], @[@"c", @""]];

NSArray *sorted = [array sortedArrayUsingComparator:^NSComparisonResult(NSArray *a, NSArray *b) {
  if ([a.lastObject isKindOfClass:[NSNumber class]] &&
      [b.lastObject isKindOfClass:[NSNumber class]]) {
    return [a.lastObject compare:b.lastObject];
  }
  return NSOrderedAscending;
}];

NSLog(@"%@", sorted);

如果您希望非时间戳记录显示在带时间戳的记录之前，则可以将NSOrderedAscending更改为NSOrderedDescending。

此外，我建议您避免将数据存储在NSArray的{{1}}中，并创建一个正确的DTO（可以定义它自己的排序功能，如果需要）你的物品。
