ios - 如何以相同的方式更改 NSMutablearray 的顺序另一个可变数组被更改

Question

我有三个数组。它们是姓名、生日 和剩余 天数，如下所示:

    name                         birthdate                 remaining 

    "Abhi Shah",                 "01/14",                  300
    "Akash Parikh",              "12/09/1989",             264
    "Anand Kapadiya",            "12/01",                  256
    "Annabella Faith Perez",     "03/02",                  347
    "Aysu Can",                  "04/14/1992",             25
    "Chirag Pandya"              "10/07/1987"              201

我想将剩余天数组重新排列成升序，但同时 name 和 birthdate 也应该以同样的方式重新排序。

请看下面这个例子:

    name                         birthdate                 remaining 

    "Aysu Can",                  "04/14/1992",             25
    "Chirag Pandya"              "10/07/1987"              201
    "etc..."

使用NSMutableDictionary将数据存储到NSMutableArray

NSMutableArray *array=[[NSMutableArray alloc]init];
 for (int i=0; i<totalRows; i++)
 {
        NSMutableDictionary *dic=[[NSMutableDictionary alloc]init];
        [dic setValue:[array_1 objectAtIndex:i] forKey:@"names"];
        [dic setValue:[array_2 objectAtIndex:i] forKey:@"birthdate "];
        [dic setValue:[array_3 objectAtIndex:i] forKey:@"remanning"];
        [array addObject:dic];
        [dic release];
 }

在你安排名称数组后，使用搜索选项使用名称而不是使用索引和使用NSPredicate 搜索NSMutableArray

中的数据

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"names matches[cd] %@", name];
 NSArray *result = [array filteredArrayUsingPredicate:predicate];
 NSMutableDictionary *dict = [[[result objectAtIndex:0] mutableCopy] autorelease];
 NSLog(@"%@",dict);// result
