Parse Plist（NSString）into NSDictionary [英] Parse Plist (NSString) into NSDictionary

问题描述

所以我有一个plist结构化的字符串，动态（不是从文件系统）。

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

我试过将其转换为NSData，然后转换为NSDictionary与NSPropertyListSerialization，但它返回[NSCFString objectAtIndex：]：

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的示例（即plist数据）。这是一个非法的选择器发送到实例0x100539f40当我尝试访问NSDictionary时， ：

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！

Thanks!

推荐答案

请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];
}
