我假设您有一个二维数组，并且由于我不知道数组中的对象看起来像我采用的是id类型，方法valueForKey:

I assume you have a 2-dimensional array and since I don't know how your objects within the array look like I take the id type and the method valueForKey:

 NSMutableArray *tmp = [[NSMutableArray alloc] init];
 for(NSArray *dim1Array in yourMultidimensionalArray)
 {
    for(id obj in dim1Array)
    {
       if([[obj valueForKey:@"name"] isEqualToString:@"Hello"])
       {
          [tmp addObject:dim1Array];
          break; // I assume you only want to add it once
       }
    }
 }
