NSDictionary dictionaryWithContentsOfFile不会按顺序加载数据 [英] NSDictionary dictionaryWithContentsOfFile doesnt load the data in order

问题描述

我正在尝试将plist中的某些数据加载到数组中

I am trying to load some data from a plist into an array

NSDictionary* mydictionary = [ NSDictionary dictionaryWithContentsOfFile:[ [ [ NSBundle      mainBundle] bundlePath ] stringByAppendingPathComponent:@"MyLevels.plist" ] ];

NSMutableArray *panelNames1;                                                         
panelNames1 = [[NSMutableArray alloc] init];

for (id theKey in mydictionary) {        
    [panelNames1 addObject:[mydictionary objectForKey:theKey]]; 
}

但是它似乎不以与MyLevels.plist相同的顺序输出到数组中.

But it does not seem to output in the same order as the MyLevels.plist into the array.

MyLevels.plist看起来像这样: [键:1值:1] [键:2值:两个] [关键:3个值:三个] [关键:4值:四个] [键:5值:5]

MyLevels.plist looks likes this: [Key:1 Value: One] [Key:2 Value: Two] [Key:3 Value: Three] [Key:4 Value: Four] [Key:5 Value: Five]

但是它按以下顺序读取:三，一，四，二，五

But it reads it in this order: Three, One, Four, Two, Five

知道为什么吗? 甚至还有另一种执行for循环的方式也可能是正确的顺序.

Any idea why?? Or even another way of doing the for loop maybe so it is in the correct order.

谢谢

推荐答案

NSDictionary对象不保留顺序.您不应该期望键的读取顺序与枚举顺序相同.

NSDictionary objects do not preserve ordering. You should not expect to have keys enumerated in the same order in which they were read.
