Question

当我提出简单申请列入以下名单时:

http://iosdevelopertips.com/data-file- management/reading-a-plist-into-an-nsarray.html

当我去掉时。我正在着手处理我的候选人名单。但当我使用以下声明时:

// Build the array from the plist  
NSMutableArray *array2 = [[NSMutableArray alloc] initWithContentsOfFile:path];

我在阵列中没有任何价值。问题是什么?

Answer 1

Here is the final solution that i got for plist....

When u are creating your plist file with first element as Array.. then its XML Contents will be as below:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Root</key>
    <array>
        <string>Firecracker</string>
        <string>Lemon Drop</string>
        <string>Mojito</string>
    </array>
</dict>
</plist>

Here you are having unnecessary tag instead of which we should have as your root element must be Array... because u are taking in NSMutableArray object...

so your plist file must be like this

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <array>
        <string>Firecracker</string>
        <string>Lemon Drop</string>
        <string>Mojito</string>
    </array>
</plist>

i have checked that its working fine....

The problem could be

The file doesn t exist at specified path, you get nil in array2.
The file exists but it cannot be read correctly, due to some format corruption, and you get nil in array2 too.
The file exists and its format is correct, but there are no values in, you get an empty array.

在使用<代码>NSString *path = [[NSBundle mainBundle] pathForResource:@“DrinkArray” ofType:@“plist”]; 假设你在你的 app子内有一个名为“DrinkArray”的正确编造的候选人名单(Array.plist)。你们的档案也抄录在旁边(Xcode中,点击你的项目,然后打造阶段,你的文件应登在Rod Bundle Ressources上)。

我猜测你将<代码>nil作为查阅档案的途径,因此,见array 2。 ry弄你的道路,检查。

Answer 3

我认为,你可以尝试这样的事情:

    NSMutableDictionary *dict = [[NSMutableDictionary alloc] initWithContentsOfFile:path];
    NSMutableArray *array = [dict objectForKey:@"Root"];

    // Show the string values  
    for (NSString *str in array)
    {
        NSLog(@"--%@", str);
    }
