将 Plist (NSString) 解析为 NSDictionary [英] Parse Plist (NSString) into NSDictionary

问题描述

所以我有一个 plist 结构的字符串，它是动态获取的(不是来自文件系统).我将如何将此字符串转换为 NSDictionary.

So I have a plist structured string, that get dynamically (not from the file system). How would I convert this string to a NSDictionary.

我尝试将其转换为 NSData，然后使用 NSPropertyListSerialization 转换为 NSDictionary，但是当我尝试访问 NSDictionary 时，它返回[NSCFString objectAtIndex:]: unrecognized selector sent to instance 0x100539f40"，这表明我的字典没有成功已创建.

I've tried converting it NSData and then to a NSDictionary with NSPropertyListSerialization, but it returns "[NSCFString objectAtIndex:]: unrecognized selector sent to instance 0x100539f40" when I attempt to access the NSDictionary, showing that my Dictionary was not successfully created.

NSString 示例(即 plist 数据):

Example of the NSString (that is the plist data):

<?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>Key1</key> 
 <dict> 
  <key>Test1</key> 
  <false/> 
  <key>Key2</key> 
  <string>Value2</string> 
  <key>Key3</key> 
  <string>value3</string> 
 </dict> 
</dict> 
</plist> 

谢谢！

推荐答案

参见 序列化属性列表

NSData* plistData = [source dataUsingEncoding:NSUTF8StringEncoding];
NSString *error;
NSPropertyListFormat format;
NSDictionary* plist = [NSPropertyListSerialization propertyListWithData:plistData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error];
NSLog( @"plist is %@", plist );
if(!plist){
    NSLog(@"Error: %@",error);
    [error release];
}
