我知道它很愚蠢，但我如何将此数组重新创建为 plist 列表

    candyArray = [NSArray arrayWithObjects:
              [Candy candyOfCategory:@"chocolate" name:@"chocolate bar"],
              [Candy candyOfCategory:@"chocolate" name:@"chocolate chip"],
              [Candy candyOfCategory:@"chocolate" name:@"dark chocolate"],
              [Candy candyOfCategory:@"hard" name:@"lollipop"],
              [Candy candyOfCategory:@"hard" name:@"candy cane"],
              [Candy candyOfCategory:@"hard" name:@"jaw breaker"],
              [Candy candyOfCategory:@"other" name:@"caramel"],
              [Candy candyOfCategory:@"other" name:@"sour chew"],
              [Candy candyOfCategory:@"other" name:@"peanut butter cup"],
              [Candy candyOfCategory:@"other" name:@"gummi bear"], nil];

感谢任何人的帮助！

Try like this but before that include your array and then follow below:-

NSFileManager *fileManager =[NSFileManager defaultManager];
  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDesktopDirectory, NSUserDomainMask,YES);
        NSString *desktopDirectory = [paths objectAtIndex:0];
          NSString *path = [desktopDirectory stringByAppendingPathComponent:@"yourfile.plist"];
         NSMutableDictionary *mut=[NSMutableDictionary dictionary];

     [mut setObject:candyArray forKey:@"yourKey"];
      If ([mut writeToFile:path automatically:YES])
       {
       NSLog(@"file created");
        }

安迪，

侯赛因的答案很接近，但在归档自定义类型时会失败。

简单的回答。由于您使用自定义类（Candy），因此您必须采用 NSCoding 协议。实现以下任务 initWithCoder、encodeWithCoder 和默认存档器将负责其余的工作。如果您想以其他格式（二进制等）存档，请参考 NSData 和 NSCoder (NSKeyedArchiver)。JSON 也是另一个不错的精益选择。

如果这太麻烦了，请放弃自定义对象并将原语嵌套在数组或字典中。这对于复杂的自定义类型是不鼓励的，并且会产生技术债务，但对于简单的结构是鼓励的。想分享 Apple 的最佳实践。

支持的 plist 类型 (iOS)

NSString、NSNumber、NSDate、NSData、NSArray、NSDictionary
