将带有 NSAttributed 字符串的字典保存到 PList 或 NSUserDefaults 中
我有一个带有 NSAttributtedString 的字典
{
9 = {
9x0 = {
UserID = 123;
formattedMessage = "Hi... How are you ?{\n CTForegroundColor = \"<CGColor 0x601e460> [<CGColorSpace 0x6010020> (kCGColorSpaceDeviceGray)] ( 0 1 )\";\n NSFont = \"CTFont <name: Cochin-BoldItalic, size: 17.000000, matrix: 0x0>\\nCTFontDescriptor <attributes: <CFBasicHash 0x6070640 [0x11f8400]>{type = mutable dict, count = 1,\\nentries =>\\n\\t1 : <CFString 0xf4d5c4 [0x11f8400]>{contents = \\\"NSFontNameAttribute\\\"} = <CFString 0x60707f0 [0x11f8400]>{contents = \\\"Cochin-BoldItalic\\\"}\\n}\\n>\";\n}";
isDeleted = 0;
isEdited = 0;
lastModifiedDate = "2011-10-19 17:27:38 +0000";
message = "Hi... How are you ?";
};
};
}
我尝试将此字典保存为文档文件夹中的 Plist 还有， 将字典保存在 NSUserDefaults 中。 两者都不起作用。 如果删除字典中的属性字符串，这两种方法都有效。
用于保存到文档文件夹中的 Plist 的代码：
NSString *aDocumentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *aFilePath = [NSString stringWithFormat:@"%@/ChatHistory.plist",aDocumentsDirectory];
BOOL aStatus = [aDictionary writeToFile:aFilePath atomically:YES];
用于在 NSUserDefaults 中保存字典的代码：
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:aDictionary forKey:@"ChatHistory"];
有人请帮忙。我错过了什么吗？
I've a Dictionary with an NSAttributtedString
{
9 = {
9x0 = {
UserID = 123;
formattedMessage = "Hi... How are you ?{\n CTForegroundColor = \"<CGColor 0x601e460> [<CGColorSpace 0x6010020> (kCGColorSpaceDeviceGray)] ( 0 1 )\";\n NSFont = \"CTFont <name: Cochin-BoldItalic, size: 17.000000, matrix: 0x0>\\nCTFontDescriptor <attributes: <CFBasicHash 0x6070640 [0x11f8400]>{type = mutable dict, count = 1,\\nentries =>\\n\\t1 : <CFString 0xf4d5c4 [0x11f8400]>{contents = \\\"NSFontNameAttribute\\\"} = <CFString 0x60707f0 [0x11f8400]>{contents = \\\"Cochin-BoldItalic\\\"}\\n}\\n>\";\n}";
isDeleted = 0;
isEdited = 0;
lastModifiedDate = "2011-10-19 17:27:38 +0000";
message = "Hi... How are you ?";
};
};
}
I tried Saving this Dictionary as a Plist in the Documents folder
and also,
save the dictionary in NSUserDefaults.
Neither of it worked.
Both methods work if the attributed string in the dictionary is removed.
Code used to save to Plist in Documents folder :
NSString *aDocumentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *aFilePath = [NSString stringWithFormat:@"%@/ChatHistory.plist",aDocumentsDirectory];
BOOL aStatus = [aDictionary writeToFile:aFilePath atomically:YES];
Code used to save Dictionary in NSUserDefaults :
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:aDictionary forKey:@"ChatHistory"];
Someone please help. Am I missing something ?
