我正在开发一个用于狮子的应用程序，我要做的是打开.WebC存档文件，修改DOM的代码段，然后将修改后的DOM写入同一个文件。
这是我到目前为止的代码。它打开webarchive，修改它，然后将其保存回文件。
NSString *archivePath = @"/Users/tigger/Library/Mail/V2/MailData/Signatures/1216DD8D-C7E2-4DE1-9FCD-0A9A3412C788.webarchive";
NSData *plistData = [NSData dataWithContentsOfFile:archivePath];
NSString *error;
NSPropertyListFormat format;
NSMutableDictionary *plist;
plist = (NSMutableDictionary *)[NSPropertyListSerialization propertyListFromData:plistData
mutabilityOption:NSPropertyListMutableContainersAndLeaves
format:&format
errorDescription:&error];
if(!plist){
printf("no plist");
[error release];
}else{
NSString *s = [NSString stringWithUTF8String:[[[plist objectForKey:@"WebMainResource"] objectForKey:@"WebResourceData"] bytes]];
NSString *new = [s stringByReplacingOccurrencesOfString:@"</body>" withString:@"hey there!</body>"];
[[plist objectForKey:@"WebMainResource"] setObject:new forKey:@"WebResourceData"];
printf("Archive: %s", [[plist description] UTF8String]);
NSData *data = [NSPropertyListSerialization dataFromPropertyList:plist format:NSPropertyListBinaryFormat_v1_0 errorDescription:nil];
[data writeToURL:[NSURL fileURLWithPath:@"/Users/tigger/Library/Mail/V2/MailData/Signatures/test.webarchive"] atomically:YES];
}
问题是生成的webarchive无效。原来是这样的：
bplist00—_WebMainResource’
_WebResourceTextEncodingName_WebResourceFrameName^WebResourceURL_WebResourceData_WebResourceMIMETypeUUTF-8PUdata:O<span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Dan Shipper</div><div>[email protected]</div><div><br></div></body></span><br class="Apple-interchange-newline">Ytext/html(F]l~îöõ°™

生成的webarchive如下所示：
bplist00—_WebMainResource’
^WebResourceURL_WebResourceFrameName_WebResourceMIMEType_WebResourceData_WebResourceTextEncodingNameUdata:PYtext/html_<span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Dan Shipper</div><div>[email protected]</div><div><br></div>hey there!</body></span><br class="Apple-interchange-newline">UUTF-8(7Ndvîöõ•∏

有人知道为什么它是无效的或者如何修复它吗？非常感谢你的帮助！
我还尝试使用Trtutul转换命令来生成WebStudio，但它不起作用，因为在我原来的HTML文件中，我有这样的图像：
<img src="http://www.domainpolish.com/images/crowd.png">
但当我使用textutil时，它会下载图像并保存如下：
<img src"file:///1.png">
即使我不想下载或更改url。我使用了noload、nostore和baseurl选项，但都没有用。
编辑：修好了！所以问题是，当我替换HTML时，我把它插入NSCORT，而不是NStase:
NSString *s = [NSString stringWithUTF8String:[[[plist objectForKey:@"WebMainResource"] objectForKey:@"WebResourceData"] bytes]];
NSString *new = [s stringByReplacingOccurrencesOfString:@"</body>" withString:@"hi there!</body>"];
NSData *sourceData = [new dataUsingEncoding:NSUTF8StringEncoding];
[[plist objectForKey:@"WebMainResource"] setObject:sourceData forKey:@"WebResourceData"];
最佳答案
更新：我只是重新阅读了问题并看到了解决方案…
您正在用此行中的错误对象替换主资源数据：
[[plist objectForKey:@"WebMainResource"] setObject:new forKey:@"WebResourceData"];
new是一个NSString对象：在替换之后，您应该将字符串内容转换为二进制数据。
[[plist objectForKey:@"WebMainResource"] setObject:[new dataUsingEncoding:NSUTF8StringEncoding] forKey:@"WebResourceData"];
