Question

我创建了一个plist文件，其中包含一个包含另外四个数组的数组。每个数组包含四个字典。我已经尝试过很多从plist文件中读取数据。但无法获取数据。我的plist文件的代码在这里

<plist version="1.0">

            <string>www.google.com</string>
        </dict>
    </array>
    </array>
 </dict>
</plist>

用于从这个plist中读取的代码是

    NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
// get documents path
NSString *documentsPath = [paths objectAtIndex:0];
// get the path to our Data/plist file
NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"Data.plist"];

// check to see if Data.plist exists in documents
if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath]) 
{
    // if not in documents, get property list from main bundle
    plistPath = [[NSBundle mainBundle] pathForResource:@"Data" ofType:@"plist"];
}

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

数组为空。

Answer 1

你的plist包含一个包含数组的字典，该数组包含四个数组，并且这四个数组包含字典。

<plist version="1.0">
<dict>
<key>Root</key>

这些行指定plist是字典而不是数组。

编辑

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

为什么您在temp使用dict

Answer 2

您错过了关闭</dict>和</plist>代码。

Answer 3

您是否尝试过这样的代码：

NSString *path = [[NSBundle mainBundle] pathForResource:@”your_Plist_name” ofType:@”plist”];
NSMutableDictionary *saved = [[NSMutableDictionary alloc] initWithContentsOfFile: path]; 
NSArray *arr = [saved objectForKey:@"root"];

for(int i =0;i<4;i++)
{
  NSArray *next = [arr objectAtIndex:i];
    for(int j=0;j<4;j++)
    {
        NSDictionary *dict = [next objectAtIndex:j];

        NSString *value = [dict objectForKey:@"imagename"];
    }
}

尝试使用此代码并检查它是否适合您。
