从的.plist文件中加载一个NSArray [英] Loading an NSArray from a .plist file

问题描述

好了，我知道这个问题似乎真的基本的，但我不能在任何地方找到一个解决我的问题 -

OK, so I know this question seems really basic, but I can't find a solution to my problem anywhere -

我有我的项目名为感受内的.plist文件。我的plist文件内容如下：

I have a .plist file within my project entitled 'feelings'. My plist file reads:

<plist version="1.0">
<dict>
    <key>feelings</key>
    <array>
        <string>Happy</string>
        <string>Sad</string>
    </array>
</dict>
</plist>

在根据.m文件 - （无效）viewDidLoad中;我想用下面的code检索plist中的内容：

In the .m file under -(void)ViewDidLoad; I am trying to retrieve the contents of the plist using the following code:

NSString *path = [[NSBundle mainBundle] pathForResource:@"feelings" ofType:@"plist"];
NSArray *tempArray = [[NSArray alloc] initWithContentsOfFile:path];

self.feelingsArray = tempArray;
[tempArray release]; 

不过，我似乎没有被加载从文件的.plist阵列和执行以下code：

However I don't seem to be loading the array from the .plist file and executing the following code:

NSLog(@"feelings: %@", feelings); 

收益（空）

任何人都可以找出我要去哪里错了吗？这一切似乎没什么问题，从我所工作过的。

Can anyone figure out where I'm going wrong? It all seems fine to me, from what I've worked on before.

推荐答案

plist文件的顶层是一本字典，而不是一个数组。您应该使用的NSDictionary 而不是的NSArray ：

Your top-level of the plist file is a dictionary, not an array. You should use NSDictionary instead of NSArray:

NSDictionary *tempDict = [[NSDictionary alloc] initWithContentsOfFile:path];
self.feelingsArray = [tempDict objectForKey:@"feelings"];
[tempDict release];
